Who will benefit from fan coils? Before us summer time - the hottest months of the year. Given the current climate situation - in the summer months temperatures in Europe are almost tropical. Some of you would certainly like to air condition your interiors with a single, universal device. Air-conditioning means maintaining appropriate air temperature conditions. It is regardless of the weather and season (which means in practice: controlling heating or cooling systems). In such a situation it is worth to consider and   install a fan coil units.

This article answers the questions about fan coils:

Firstly, what are fan coils units?

Secondly, what are their advantages?

Thirdly, what types of fan coil units are there?

Finally - how to increase the effectiveness of their work?

What are fan coils units?

Fan coil units are heating and cooling devices whose task is to maintain the optimum temperature in the room. How do they work? Simply put, on the principle of heat exchange with the environment through fans. This is a practical, common solution used in public buildings. Fan coil heats, cools or heats and cools the interior. Heating and cooling medium here is water.

Fan coil units are generally used in large buildings (office buildings, auditoriums, cinema halls). But there is no objection to install them in private homes for the convenience of the householder. The condition is to have a hydraulically prepared cooling system.

Advantages of using fan coil units

- low thermal inertia allows quick adjustment of air temperature to current needs

- versatility (heating and cooling) and simple operation

- thermal comfort all year round

- space saving thanks to small dimensions

- air cleaning and filtering - its high quality thanks to ionization filters

- beneficial microclimate to the people with allergies

- eco-friendly: unlike an air conditioner, a fan coil heats and cools the air using water medium not freons. They are chemical compounds whose emission to the atmosphere causes damage to the ozone layer

What types of fan coil units are there?

Fan coil units: division by construction

  1. Two-pipe and four-pipe

2. Fan or induction-based operation

A two-pipe fan coil has only one heat/cool exchanger. So, it either heats or cools (requires switching from cooling to heating and from heating to cooling).

A four-pipe fan coil is a unit with two exchangers, which can operate both modes simultaneously.

The commonly used fan coils use fans for their work (to force air circulation). On the other hand, induction-based devices don’t have a fan, but uses the power of induction of external air. The air is sucked in, directed to the exchanger, heated/cooled and then blown out into the room.

Fan coil units: division according to the installation method

  1. Underfloor-installed: built up in special housing inside the floor

2. Ceiling-installed: depending on the variant, mounted horizontally or vertically

3. Cassette-installed: the most popular variant, mounted in the suspended ceiling

4. Wall-mounted: designed to be placed on the wall

To sum up, most fan coil units available on the market provide: simple installation. Also -, easy access and economical, efficient operation in spaces. However, their functionality can be multiplied.

Fan coil units can work even more efficiently

How? By using modern, automatic control. Properly selected control system can avoid overheating or overcooling of the interior.

SALUS Controls offers multifunctional, room controller designed to control two-pipe or four-pipe fan coil units: FC600 device.

Why FC600?

Fan coil units users can experience increased thermal comfort due to the accuracy of control offered by the FC600 controller. The device is equipped with TPI control algorithm. It controls fans and valves in very precise way. In order to reach and maintain the desired temperature setpoint in the room. In a two-pipe system, V1 output controls heating and cooling, in a four-pipe system, V1 output controls heating and  V2 output controls cooling.

Our FC600 controller will successfully control trench heaters or water heaters with built-in fans. Multiple settings and configurations (FC600 operates according to time/temperature schedules) allow it to be used in many types of interiors. The main benefit is improved temperature control and continuous monitoring of heating/cooling parameters - also via the Internet. In order to control FC600 from mobile devices or web browsers (Online mode) it is required to have  Internet connection and UGE600 Internet gateway available from SALUS Controls offer. Online mode provides immediate access to the latest device updates (updates are made automatically).

Owners, investors and installers of smart home systems know that this purchase is an important investment. It improves the comfort of life. You want to know what kind of expenditure you have to take into account. And here we disclose right away that there is no single answer to this question. It all depends on the property and the needs and expectations of its users. Our system configurator will help with this case.

You will learn from the text:
• what is SALUS Controls system configurator and what is it used for?
• what does the cost of system installation depend on?

Smart Home is more than convenience

Comfort is not limited only to remote shut off the iron or turn on a lamp. Smart home control means:

a. optimal heating control: the ideal temperature in every room
b. home economics: lower expenses for energy consumption
c. control of appliances such as roller blinds, lighting, garden sprinklers
d. security of property: alarm sensors, SMS notifications
e. environmental protection: lower emission of pollutants
f. everyday comfort and convenience

Intelligent home today is associated with modernity, energy efficiency, safety, control of expenses. The scenarios of dependencies between devices working in the system are almost limitless. However, the question of creating a system and its price remains open. That is why SALUS Controls technical specialists have created a system configurator.

System Configurator - what is it?

SALUS configurator is a user-friendly selection tool. It helps installer/user to assemble products and create a system best suited to the needs of household members. We have architecturally different houses/apartments, different types of heating systems. The rhythm of life of each of us is also different. So there is no universal system. Such which pre-programmed settings will meet the expectations of all. That's why control elements of intelligent house have to be chosen individually. "Made to measure", like clothes at the tailor's.

Select the products for your type of heating in configurator

SALUS configurator was created based on our experts' experience gained from talking to customers calling the Technical Support Hotline. Knowing what their most common questions and problems are, we created a tool. It can be called "virtual version of an advisor". You can use it at any time, working at your own pace. Or choosing different product combinations and calculating control options and costs in real time.

Selection of type of heating in configurator

Using SALUS Controls configurator in the "user" option consists in answering a few basic questions.

They are about the technical conditions of the building (type of installation, floor space, number of radiators, etc.). This information is crucial for the selection of control devices. In the "installer" option, the questions are of a more technical nature. For example we ask about the number of manifolds -which corresponds to the number of wiring centres needed. Or about the number of loops connected to the manifold.

After providing the answer, the configurator indicates the list and the number of products needed; the available variants from which you can choose the right one in terms of function, price, design.

Finally, the configurator proposes optional products, i.e. those that may be necessary during the installation. They can be temperature sensor, protective head cover, 16A relay module, additional ZigBee network amplifier. In this way an outline cost calculation is created.

Smart home - how much does it cost to implement a system?

Where to start?

At the beginning you need to know whether you care about controlling heating via the Internet. On the one hand, this option requires an additional fee. On the other hand though - incomparably increases the convenience and functionality of the entire system. Then you need to specify what type of heating you want to control: radiator, floor, electric. If mixed heating is involved, you need to take into account the products needed for both types (floor and radiator). Smart Home accessories are an additional cost.

Characteristics of a sample house

Basic building of which we will indicatively show the operation of our configurator, is one-storey with a usable attic. Downstairs, there is an underfloor-heated living room with a kitchen and a bathroom. In the attic there are three radiator-heated bedrooms, each with one radiator. Altogether there are five rooms. The bathroom has one window. Let's assume that the residents have decided to control their home via the Internet, using selected SALUS Smart Home accessories. What products did the configurator indicate? What will the household gain thanks to them?

Explore the possibilities: how does the configurator work?

Let's divide home control areas into four categories:
1. Heating control
2. Control of lighting and roller shutters
3. Example OneTouch rules
4. Fault detection

Heating control

For control heating in such a designed house via the Internet, you need to have temperature thermostats. Modern Quantum SQ610RF with a built-in humidity sensor and Warm Floor function it is a good proposition. Optimal control of the heating is achieved by regulating the temperature in each room. Then you always need as many thermostats as many rooms. A surface-heated downstairs requires a wiring centre and actuators (e.g. self-regulating actuator THB). To control three radiators in bedrooms, you need to buy three wireless thermostatic heads. And of course the "heart" of the system, without which there is no way to manage your home online - the Internet gateway UGE600.

Choosing number of actuators

Control of lighting and roller shutters

If you want to create functional OneTouch rules for lighting and roller shutters, to the cost of the system should be added accessories (selection of devices depending on the rules):

1. Smart Relay (SR600)
2. Roller Shutter (RS600)
3. Smart Plug (SPE600)

Choosing devices for underfloor heating

How do these products work? Smart Plug, as an extension of the electrical outlet, controls the devices plugged into it. Smart Relay allows to control a receiver with a load power up to 16A. Roller Shutter controls drives of window roller blinds and lighting (230V AC). Thanks to these small devices, you can adjust the moment of switching on or off the lights in selected rooms or make lamp operation dependent on other actions, e.g. entering a room, closing a window, starting a fan, etc. You can also use them to simulate the presence of household members when the house is empty. The final cost depends on how many roller shutters/devices in your house you want to control.

What OneTouch rules can you create?

In SALUS Smart Home application you will program dependencies - scenarios of devices' work. For example:

  1. At sunset, a lamp will turn on in the hallway, and at sunrise - it will turn off.
  2. In the morning, the roller blinds in bedrooms will open to 30%, after an hour to 60%, and after another to 100%.
  3. While the window is open, the heating in the bathroom will turn off.
  4. At 8pm, the temperature will drop from 22 ℃ to 20 ℃, but the bathroom floor will remain comfortably warm until 11pm.
  5. When you press the OneTouch rule activator mounted at the exit door, the set temperature in all rooms will drop to 18 ℃, the blinds will close in the living room and dining room, and the lights will turn off.

To implement these scenarios in our example home - in addition to the Internet gateway, application (free) and temperature thermostats - we need: a minimum of five Roller Shutters for automatic operation of roller shutters, an opening sensor for the bathroom, a button that activates the rule when leaving the house, smart plugs, the number of which depends on the number of lamps that are to turn off when leaving. So let's assume that you need two Smart Plugs and a Smart Relay.

You can think about all this in no hurry. After making a decision enter it into the fields of the configurator.

Fault detection

Sensors detecting home faults are part of the SALUS Smart Home series. It means that they require a gateway and an application to work. Depending on which, where and how many sensors we want to install, the following amounts must be multiplied:

Choosing quantity of PS600 Temperature Sensor in configurator

How do these devices work? A smoke sensor detects smoke. A flood sensor detects water on surfaces or contacts. An opening sensor indicates which windows/doors have been opened and allows the heating to be turned off for ventilation. The devices in the system allow you to receive SMS messages about an event.


The offer is rich, but do you have to be rich to take advantage of it? SALUS Controls offers customers not only exclusive premium lines, but also good for start, standard variants of products. They work well and at the same time will be friendly for your wallet.

Use our configurator and check, which solutions best suit your needs. Data entered into the configurator will help you find out how many and which devices you will need to control your home. Also it will create a rough estimate of the entire project.

What is important, the amounts will be approximate - calculated based on net list prices. Remember that our distributors will certainly offer you a favorable discount.

In case of any doubts, our well-trained installers and SALUS Controls technical team will be happy to advise you.

Why don't you choose a heating control system?

A heating control system is needed in every place where people live and work. Thanks to it, the heating system does not waste heat energy, and the right temperature improves well-being and supports our biological rhythm - improves concentration, quality of rest, sleep. We have written about this many times. However, still not everyone decides to install a control system. Today we try to answer the question of what stands in the way of this decision. Why do some of us not control the heating in our home? We present the 4 most common concerns and explain why they are wrong.

Concern 1: "What do I actually need it for?"

Modern heating controls - both radiator and underfloor heating - are wrongly associated with luxury. Something that comes in handy, but is not so useful as to be essential. So much for the efficient intake of heating fuel provided by a heating control system, this is no luxury. Here, it's really about something more than convenience and thermal comfort - which we are willing to sacrifice, especially now, in tough economic times.

Temperature thermostats are not a luxury good, but a utility good.

They were created to consciously consume the heating medium throughout the winter season. Accurate control algorithms and well-thought-out schedules allow us to adjust the temperature to how we live and prevent energy waste. We use only as much energy as we need to.

But this only happens with devices that constantly control this process. Further conclusions follow: if our installation uses less heating fuel, we pay lower energy bills.

What about zone control?

Then there's ZONE CONTROL, which we sometimes don't consider at all, thinking it's unnecessary ("Why do we need a thermostat in every room?"). It seems to us that if we buy one thermostat and install it where we are most often, it is enough to control the heating. However, this is a dead end, because then we will have the optimal temperature only in this one room - in the other rooms it will be random. So what if, for example, the living room will be pleasantly warm (because the thermostat will make sure the comfortable temperature there), if the rooms of other household members will be cold? In the end, it will force us to raise the heating parameters, so there is no way to save money.

What's worse, in such a situation, the main room - the one with the thermostat and the one where it was supposed to be perfectly warm - will be overheated. Only thermostats working in each room separately will actually allow us to adjust the temperature to our expectations - no matter what kind of heating we have, what kind of heat source. The intake of the heating medium will be economical and ecological. And then we will pay lower bills. And this is what a heating control system is needed for.

Concern 2: "Too expensive."

Since the heating control system is associated with luxury, the concern of the unconvinced may be its price. Because, as we all know, you have to pay a lot for luxury. So the idea that the control system is expensive may hold us back from buying it. This thought discourages us from doing the calculations and checking "how expensive". Maybe not as expensive as we thought after all?

We treat the investment in advance as an expense and not as an investment in saving money. And that is exactly what it is - an investment in saving money and energy, as we wrote above. So if we look at this one-off cost as something that will pay off and pay off in lower heating energy consumption, the price will no longer be a scaring. It will be a contribution to a 'cheaper tomorrow'. After all, it is a well-known fact that you have to invest to gain.

In addition to all this, the product range is rich. Among SALUS Controls thermostats you can find models at really affordable prices. After all, ZONE CONTROL does not require the purchase of the most expensive thermostats at once.

Yes, they will work if you want the latest solutions with many features, such as an integrated humidity sensor or a comfortably warm floor option (with underfloor heating).

Such thermostats offer the possibility of expanding the smart home system and creating scenarios of device dependencies (tap to run), which is a great help in running a household. However, if you do not care about such advanced functions or controlling your heating via the Internet, there are cheaper products to choose from. Cheaper, but still proven and effective.

Concern 3: "Too much trouble, difficult to manage".

The very name "heating control system" sounds like something complicated, something you have to learn, something you have to know how to handle - so that it works as it should, and so that you don't break anything. This can be a discouraging factor, because technology sometimes scares us. Especially if you feel that once you have brought it under your roof, you are left alone with it. Not everyone feels like reading long instructions and then figuring out everything by trial and error anyway. And there is some validity in this concern - home automation requires a certain amount of knowledge. But, if you choose well, it's not a barrier.

Many brands - such as ours - take great care to ensure that the customer is not left alone with the technology after purchase. SALUS Controls offers continuous and free assistance in the installation and then in the operation of the devices. It can be used by installers as well as individual customers. At the same time, permanent assistance is one that lasts for the entire life of the heating control system.

Thanks to the experience and knowledge of our installers, even at the installation stage of the system, the customer has the chance to ask questions and clear up any doubts. The installers explain everything in detail. They support the customer not only during installation, but also during start-up and operation.

Finally, we try to ensure that the user manuals for our products are not big books, in which it is difficult to find the information needed. Our abbreviated manuals are specific information that the customer needs to know in order to operate the purchased equipment correctly. Everything is described and supported by clear diagrams. On our YouTube channel, we regularly post instructional videos in which we show, step by step, the process of pairing drivers and implementing the system. So there should be no fear of handling our equipment. The customer is never left alone with the technology we create.

Concern 4: "A heating control system is an idea that is only good for new houses".

It is also a myth that a heating control system is only for new buildings. This is not true.

Of course, the installation of 230 V appliances does indeed require the routing of cables, which often involves renovation work, forging of walls, etc. Therefore, it is much easier to plan it during the construction phase of a building or premises. The more extensive the system, the more thoughtful the installation work should be. However, this is not the rule.

If you decide on a heating control system made entirely or mostly of wireless products, annoying renovation work is out of the question. Of course, signal strength is important for the smooth operation of the system. Therefore, it is worth knowing that in the SALUS Smart Home system, each 230 V device strengthens the wireless signal, in a way becoming a repeater. This allows you to build a solid network of home devices.

So, a heating control system can be successfully installed in any building/apartment - including one that we have lived in for a long time.

Are we sure we know the possibilities?

There is another reason why we do not always control our heating system. This reason is the fact that we are not aware of how good a heating control system we can create for ourselves. And not necessarily in houses, but also in flats. People simply don't know that they can do this and how much they can gain by, for example, already owning a 2-3 room flat. And they can gain the same things as homeowners - comfort and savings.

What does it take to create a functional and economical system in a flat?

You will need intelligent TRV thermostatic heads mounted at the radiators (radiator heating), room thermostats and - for example - opening sensors to place at the windows. With these devices, you will gain control over the consumption of heating fuel:

Examples of such rules for flats can be multiplied, depending on the needs. And your imagination.

But is underfloor to the only option? Check out the variants of surface heating.;;https://salus-controls.eu/2022/10/28/is-surface-heating-just-an-underfloor-heating/;;Is surface heating just an underfloor heating?;;

In the modern building industry, surface heating replaces standard radiators. In the case of underfloor heating, the wires hidden in the floor distribute heat evenly over all heating zones in the building, working at low supply temperatures. This allows you to heat the house economically and ecologically. However, what types of surface heating do we have to choose at all? For sure, it's not just the underfloor heating.

Low-temperature surface heating – how it works?

Surface heating is a type of heating system in which the entire room is heated by invisible to the eye pipes with spiral or meandering arrangement. They are concealed in the floor, but can also be installed in the ceiling or wall. The heat source (heating factor) can be: water, air or electricity. Obviously, this type of heating has a much larger surface area than radiators and gives off heat to the entire heating surface. It works on the principle of radiation, in much lesser degree of convection. As a result, it heats evenly and slowly - it also loses heat slowly. To maintain a comfortable temperature (about 22-23°C) in the room (in the heating zone), surface heating needs a low supply temperature (up to 30°C), which is not only environmentally friendly, but also economical.

Why is it like that? It's pure physics. If we want to reduce the thermal parameter of the supply, we have to increase the heating surface. And this is what happens in surface heating.

What is most important, the low supply temperature of the surface heating works well with eco-friendly heat pumps, which are becoming increasingly popular among forward-thinking investors.

The advantages of surface heating have been discussed many times (e.g. here). To summarize them, you need to know that – in comparison with radiator heating – surface heating is more efficient and healthier. It is also more comfortable for householders, because with lower supply temperatures and gradual heat distribution, the house is never overheated. Warm air does not "hit in the face " as it happens in the case of radiators, that "throw out" the hot air that is floating to the ceiling. The result is that, the radiator distributes heat very unevenly – the further away we are from the radiator, the colder it is for us, and sitting by the radiator we can hardly bear the heat. Another issue is the air quality. Surface heating does not dry the air, and radiators do. Very much. Radiators also collect dust in the recesses on their surface. They cause movement of air; they carry pollutants, forcing us to inhale them.

If you are interested in surface heating, let's take a quick look at the possibilities.

Types of surface heating

Heating loops hidden in the floor

In the case of underfloor heating - the most popular version of surface heating - the manifold distributes the heating factor (e.g., water) through pipes or heating tubes, hidden in the floor. This is added comfort of stepping on a pleasantly warm floor, although in practice it comes down to the fact that - except the bathroom, where the floor is actually perceptibly warm - in other rooms it is not simply unpleasantly cold. The most outstanding is that what the floor is covered in. The best heat conductors are ceramic tiles, laminated panels, waterproof vinyl, resin flooring, wood (so materials with low thermal resistance). Underfloor heating is the most efficient and unquestionably the most popular version of surface heating - it brings thermal comfort at the lowest supply temperatures.

Heating elements hidden in the ceiling

With ceiling heating (installation behind e.g. a false ceiling), the heat radiates evenly from the ceiling to the structural components of the building and to the objects in the interior. We feel the heat at head level, not leg-height. In this case, we will not benefit from the comfort of a warm floor. For many builders, this is a disadvantage, but there are also advantages: there is no risk of covering the heating surface with a carpet or disturbing the installation when hanging cupboards or decorations (as with wall heating, for example, which we will discuss in a moment). On the other hand, we must take care of the insulation of the building. The supply temperature for ceiling heating is usually higher than for underfloor heating, because the heat does not fall to the ground. To ensure that the heating effect is satisfactory, supply temperature needs to be increased.

Heating loops hidden in the wall

Wall heating is the least common form of surface heating. Heating elements are permanently built-in in the walls and emit heat through them, warming the interior. As with underfloor and ceiling heating, the heat spreads gradually without overheating or raising dust. There are no additional layers here to reduce efficiency (e.g. panels, carpets). However, you should be aware that with this solution, the usable area of the room is reduced - it becomes smaller by the thickness of the installation built into the wall (this is especially noticeable with air heating). With this type of surface heating, it is also necessary to set a higher flow temperature than with underfloor heating (up to 45℃). However, it is still economical and low enough not to cause damage or burns in the event of possible contact.

Water, air or electric surface heating?

Where to install the heating elements is one thing, but the heating factor you ultimately decide on - water, air or electricity - is crucial. The running costs of the surface heating, and therefore of the entire house, will depend on this important choice.

The water heating system heat the building through plastic or metal pipes through which hot water flows. The installation is insulated and protected against leaks or moisture. This is important to prevent corrosion, rusting or rotting of the heating elements.

Air heating system is characterised by the fact that there are special channels in the ground or wall in which heated air circulates - it is set in motion by an internal fan.

Electric surface heating is based entirely on heat conducted through heating cables or foils. Its main advantage is the ease and 'cleanliness' of installation and convenient operation, while the obvious disadvantage is the price of the heating fuel. Electricity is expensive, especially with such increased use.

Or maybe capillary tube mats?

They are still a kind of market "innovation", which is why it is worth mentioning that they exist and represent an interesting variant, or rather alternative, to the installation of surface heating. These are the so-called capillary tube mats, i.e. light and thin chains of polypropylene tubes through which the heating factor (water) flows. They are installed with screws into the surface (floor, wall, ceiling) before plastering. The capillaries are flexible and can be formed, which means that they can be placed on architectural elements of different shapes and cross-sections - e.g. on a semi-circular wall, a suspended ceiling, in the attic (bevels). Capillary tube mats are not only lightweight, they also operate quietly (quieter than surface heating) and do not actually reduce the usable area of the room.

When choosing capillary mats, it is important to remember to install them in walls for which we have no long-term decorating or renovation plans. Accidentally drilling through the plastic tubes (e.g. when hanging a painting) can cause damage and expose us to unnecessary repair and renovation costs. Such a wall cannot be covered by a large piece of furniture - then the operation of the mats misses the point. However, these are limitations which equally apply to wall-mounted surface heating.

At the moment, the biggest disadvantage of capillary tube mats is the high installation price. When buying them, pay attention to the quality of the materials used and the solidity of the welds.

Surface heating - what is the purpose of temperature control?

Each room in a building has an individual need for heat. Rooms may lose it at different rates, but they also have different functions, so they should have different temperatures. This is why it is important to introduce zone control, which involves installing thermostats separately for each heating zone. Then each room will have its own set temperature. Of course, with air heating (radiators) this is also important and necessary, but underfloor heating in particular needs precise control. This is because of what we essentially consider to be the advantage of this installation - it is slow to heat up and slow to give off heat. With this operating mechanism, the heating schedule must be logically thought out, planned in advance and monitored by controllers.

Manually, we are unable to operate the surface heating comfortably and efficiently.

Choose heating control;;

Energy fuel prices will continue to rise. It's hard to predict at what level they will be in the coming heating season, as well as in the following ones. Energy conservation awaits each of us. How to reduce energy expenses on your own, without losing comfort? Prudent use of heating fuel is the first thing that comes to mind, but improving CH efficiency will pay off more.

Discounts or subsidies will not stop rising inflation. They will only postpone its unpleasant effects. If we're in the mood for it, we can joke that it will be cheapest to light a fire and rely on the traditional way of heating the house. Only that jokes, while they certainly help to endure reality, will not translate into energy savings. Let's rethink our steps during this difficult time.

Replacing the installation with a more economical one is not the only option to pay less. However, not everyone can afford such an investment, while everyone wants to do something to reduce the expense of heating the house. Besides, even if we decide to upgrade the entire CH, we still have a chance to increase savings. It is given by installing the right control system for the heating system - any kind.

Why does temperature control save heating energy?

It doesn't matter whether we heat the building with a solid fuel boiler, liquid fuel boiler, electric boiler, gas boiler. Or maybe we heat the house with an ecological heat pump? It doesn't matter either. What matters is primarily the way of the installation consumes the heating fuel we pay for. This way can be wasteful if we do not use controllers for heating. Investing in them will definitely be cheaper than replacing the installation, and will bring the desired results. That's because automating energy consumption is low-carbon and energy-efficient. It protects the environment and - which is now hugely important - reduces bills.

Installation of the control system is not complicated or hard. Well-known brands, such as SALUS Controls, offer free support during the selection, installation and subsequent use of control products. Saving energy is easier than it seems.

The heat source (boiler, heat pump), controlled by heating automation, produces only as much heat as it really needs to maintain the temperature we set. There is no overheating of the interiors or cooling them, after which even more energy is needed to restore a comfortable temperature for us. Of course, room thermostats do not affect the price of heating fuel, but they help to manage its intake. As a result, heating costs are reduced no matter what type of fuel we heat the house with.

Zone control and energy savings

If the heating of a building is based on measurements coming from only one room, such as the living room, where the thermostat has been installed, the temperature in the other rooms will be random. This is neither efficient nor, of course, comfortable. Someone will always be either too cold or too hot. Zone control allows you to easily manage the heat of each room separately.

Investment in one thermostat seems to be a smaller expense than the one-time purchase of several temperature thermostats - needed for zone control. However, this is a that simple, since such a calculation is about the initial expense, not energy savings. Over the course of the building's operation, zone control will save on energy consumption, which will increase the savings from buying just one thermostat, installed in the most frequently used room.

Control automation by SALUS Controls

SALUS Controls offers energy-saving devices for temperature control in buildings using any type of heating: radiator, underfloor, electric, fan coil. There is a choice of modern thermostats operating by wire, wireless, via the Internet - the SALUS Smart Home system.

It is worth taking a closer look at the devices that support daily energy savings, because temperature control helps optimize the operation of the heating system not only in private homes, but also in commercial premises, workplaces, offices or hotels.

Energy saving vs. controllers - how does it work in practice?

With zone control, that is, installing a temperature thermostat separately in each room, we can reduce the heat by a few degrees in places where we are less often present (such as the hallway). The same, when no one is at home. A few days or even hours a day of economical temperature will make a difference when paying bills later.

According to experts, lowering the temperature in homes by 1℃ saves 6-7% on energy bills. If we translate this over the entire heating season, the numbers starting to be major. Consciously lowering the temperature - without sacrificing comfort on a daily basis - will save concrete amount of money.

Energy price increases - pay less with heating automation

In the coming months and even years, the heating industry will not escape severe increases. Market analysts also warn of rising electricity prices. As we mentioned at the beginning, the cost of operating buildings will rise. We can’t escape this change. To feel them less „painful”, we need to save energy on our own. Temperature control is no longer a luxury, but a necessity.

Less heating fuel is consumed by maintaining a constant temperature in the building. During the absence of household members, the building should have an economic (lower) temperature. The installation should not be turned off completely, as this will cause the interiors to cool down, which will have to be reheated. Meanwhile, the installation uses more energy to heat cold interiors than to maintain an economic temperature in them. That's why it's worth relying on heating automation.

SALUS Smart Home and energy saving

Reasonable consumption of heating fuel goes hand in hand with technological trends. Therefore, the modern smart home is no longer just a matter of convenience and comfort - although, no doubt, this is an advantage. SALUS Smart Home is more than convenience. It is an energy-saving potential that must be used.

How do smart home solutions help save energy?

When we hear "smart home solutions," our first thought is voice-activating a playlist of our favorite songs or turning on a light at the clap of a hand. And that's right - home automation provides convenience, creates a cozy atmosphere. It is compared to technological magic. But a smart home can do so much more. Especially in difficult economic times, when energy saving is precious. And here too, you can put your trust in technology. Savings begin at home.

Do smart solutions help save energy if they are expensive? Are they really expensive?

High price is an effective " repellent " of any service, goods, industry. All more so if we do not want to spend, but we want to save. Smart home is associated with something expensive and exclusive. With something that only a few can afford. With something that will not help to keep money in the household budget. However, such thinking is wrong. Smart home solutions are not just gadgets in luxury properties. Of course, they improve the daily comfort of homeowners, but a large part of smart solutions are devices that thoughtfully improve the operation of home installations. And if the home installations work optimally, they consume less energy and create financial reserves. It usually doesn't take long for that to happen.

Remember that energy is a regular (and growing) expense, and the equipment that determines its consumption is a one-time expense. Since energy costs a lot, it is necessary to manage its consumption wisely. If we do not take care of it, we will waste it unnecessarily and pay even more. Why should I waste energy? - someone will ask. And probably few of us consciously do it. Unfortunately, it does not always depend on the responsibility and self-discipline of the householder. Without the support of controllers it is impossible to avoid wasting energy. We ourselves are not able to set the consumption in such a way that some of the energy "sucked in" by the household installations is not unused. We pay in vain. Therefore, saving energy in every home should be a priority.

Which smart solutions will work for you?

On the market we can find many more or less technologically advanced devices that help save energy: intelligent heating systems, lighting, security systems. We have many smart solutions to choose. So the question is - which ones to skip with no regrets, and which ones to be interested in.

Wiring centres, actuators, thermostats, TRV radiator heads

Heating controls are one of the most important categories of smart solutions for energy efficiency. In our geographical zone, we have to heat our homes for about 8 months a year. The winter season starts in early autumn and ends in late spring. Heating expenses drive gigantic costs. To keep them in control and save energy, we need modern technologies. Maybe not all smart solutions are as spectacular as chatting with a voice assistant, but we need them badly.

A well-designed wiring centre for surface heating (e.g. for underfloor heating) will be an ideal example here. It allows to control the distribution of the heating medium to individual loops by means of thermoelectric actuators (actuators open/close the flow). And how do the wiring centre and actuators (or the heating unit itself) "know" how to distribute the heating medium to maintain the temperature? Thanks to the room themostat. At the right moment, the temperature thermostat sends a signal to heat or stop heating. This is caused by continuous measurement of the room temperature and comparing it (according to an established algorithm) with the set temperature. Similarly, in the case of the TRV radiator head - although it is already a part of the radiator installation - which, in cooperation with the thermostat, distributes heat to radiators.

The human mind cannot replace the algorithms and technical devices that control the flow of the medium in the heating system. It is pure engineering and mathematics. Control systems are a group of smart solutions that most support energy saving. They provide optimal heat at the lowest possible cost. Not to mention that the ideal temperature improves living comfort and promotes well-being.

Small smart solutions: smart plugs and sensors

Smart plugs, or intelligent plugs (commonly called smart sockets), are small devices with huge power. They don't cost much, but they can make life more enjoyable and save energy. How do they work? Really simple. The smart plug is connected to the electrical socket. It becomes its extension with special functions. If we connect an electrical device such as a lamp to such a mounted plug - which happens most often - smart plug will turn it on or off at selected moments. Thanks to this it will not be lit when it is not needed - it will consume less power and we will save energy. Such an expanded socket will also work well in the so-called intelligent house scenarios. For example, it will allow you to control the lamp depending on the work of another device, or from sunrise, sunset or selected time. There are many more combinations. For example, you can set the light to go off when the temperature in the bedroom drops. The situation is similar with sensors - for example with a motion detector. You can create a rule that turns off the lights when there is no one in the kitchen (when the motion stops). Of course, to make it work the way we want it to, we first need to program the appropriate rules into the smart home app (such as this one). This is done only once and then the house "lives" according to our rules.

It is also worth paying attention to other sensors that will help save energy. For example a light dimmer (more here) or an opening sensor, which will signal the opening of a window and - included in the rule - enable turning off heating in a ventilated room. Why pay for heating your balcony or backyard? A flood sensor will also be useful; properly connected to the home's plumbing system, it will shut off the water supply to the bathroom after detecting a washing machine malfunction. So we can save not only on energy consumption but also on renovation costs.

Smart solutions help save energy – summary

In these difficult economic and ecological times there is also good news. For example, modern technology allows you to reduce energy consumption. Just sit down with the idea, check the possibilities and bet on smart solutions that will help control this essential daily process. Each of us lives differently, has different habits, different needs, differently organized home space. Therefore, before we decide on any purchase, we should consider which technical innovations will help us optimize energy consumption. This is important especially with installations that consume the most money (heating, lighting). Remember that control systems are an investment that will pay off for years. After all, even simple models of thermostats allow you to maintain the right temperature in rooms. Not to mention those with extensive schedules. With these, energy consumption will no longer be accidental.

Check what not to forget!;;https://salus-controls.eu/2022/06/13/heating-installation-in-the-spring-and-summer-season/;;Heating installation in the spring and summer season;;

The winter season is over. We are entering a time of rest for our heating systems. During the cold seasons, radiators and underfloor loops are running at full steam. However, they should not be forgotten during the warm months. Spring and summer are a good time to refresh buildings and heating system components in homes, schools, and workplaces.

From this text you will learn:

Renovation step by step

It is a good habit to regularly check the usage of all equipment working in your home/apartment/office. Prevention allows you to avoid unpleasant surprises like sudden failures and high costs of immediate repairs, when something is needed "right away". When it comes to the heating system, checking the efficiency of the devices which are in use for a large part of the year seems to be especially necessary.

How to do it?

Here are 4 important points that should not be overlooked.

Inspection of the installation

Periodic technical evaluation of the heating system is a matter of both heating efficiency and your safety. Irregularities can increase the operating costs, as well as threaten the health and life of residents/employees (e.g. cases of carbon monoxide poisoning). When deciding on the inspection, it is necessary to check not only the chimney (in case of solid fuel boilers) and the boiler, but the whole installation - the tightness of central heating and hot water circulation, the condition of pipes, the condition of the underfloor heating manifold.

When inspecting the condition of the chimney, it is necessary to check the patency and tightness of the chimney ducts, as well as to make sure that the smoke, fumes, and ventilation ducts are cleaned. This service can be provided only by persons with the title of a master chimney sweep or with an appropriate building license.

When inspecting a boiler, it is important to reliably assess the efficiency of its automation - motors, pump, fan, valves - and to evaluate the combustion efficiency. What is the purpose of flue gas analysis? Proper setting of boiler operating parameters. It involves measuring O2, CO, CO2, and NOx, as well as determining values such as efficiency, chimney loss, excess air factor, draught, etc. It is worth remembering that as a result of worse combustion, soot settles on the heat exchanger, which increases the consumption of heating fuel - gas, fuel oil.

According to the applicable regulations, the inspection of the heating system elements should be made once a year, which is confirmed by an appropriate protocol.

Routinely performed:

- cleaning of components - especially the combustion part

- inspection of ignition and ionization electrodes

- inspection of safety devices/sensors (chimney draught, overheating, gas outflow)

- inspection of wiring, electrical and hydraulic connections

- replacement of worn-out elements: filters, gaskets

- diagnostics of possible defects in the equipment (cavities, cracks, etc.)

- adjustment

- trial start-up (checking for possible air aeration).

It is also worth taking care the inspection of home electrical and gas installations. The inspection should include electric shock protection measurements, evaluation of electric switchboard protections, and checking ventilation in rooms where gas-powered devices are used.


Why is a review important?

Cleaning and venting radiators

Before running traditional radiator heating for the first time in the season, it is important to clean the radiators of dirt. During the summer, when they were not used, dirt formed on their surface and inside. If we do not remove it, after a few days of even not very intensive heating, an unpleasant smell of burnt dust will rise in the air. This is unhealthy for the human respiratory system and dangerous for allergy sufferers.

To wipe the radiators, use brushes with fine bristles and soft cloths that will not damage the painted surface. Internal cleaning is best done with a brush attached to a long wire with a handle. This will allow you to better reach all nooks and crannies. To get between the radiator panels more easily, you can remove the top radiator cover (the so-called grill) and the side covers.

Sometimes we hear water bubbling, hissing or whistling in radiators during the first start-up. These are signs of aeration. Water with air bubbles has accumulated inside the radiators, making it impossible to distribute heat. Therefore, vent the radiators, equalize the pressure in them and refill the water level.

Venting can be done by yourself. For this purpose you need to unscrew the valve (usually located in the upper part of the radiator) with a special key. Air will flow out of the valve, then air and water, and then water will flow out - then we are sure that the radiator has been vented. You can turn off the valve, equalize the pressure and water level in the system. The pressure will be read from the pressure gauge located on the furnace. This is usually between 1 and 2 bar. If it is lower, water should be let into the system through the valve located on the furnace. In order for the radiator heating to work effectively throughout the season, it may be necessary to repeat this operation after some time.

Why go for it?

Temperature thermostats are effective in saving energy (and money) because they prevent rooms from overheating. The optimum temperature inside the house is about 19-24 degrees Celsius (depending on individual preferences). For the thermal comfort of household members, it is good to make sure that the temperature in the rooms is not accidental and always maintained at the right level. It is also worth remembering to turn off the heating when ventilating and lower the temperature by 3-4 degrees when no one is home.

How do you make it easy?

By installing modern building automation. Thanks to SALUS Controls control devices - we are talking about e.g. Quantum SQ610 thermostat - temperature in your house will return to comfortable settings just before your family members return. Thanks to Smart Home products - we are talking about e.g. an opening sensor - heating will be automatically turned off in a ventilated room.


If you want your heating to work optimally, which means the best it can, take care to check the condition of your heated building during the spring season. If necessary, have it repaired. Especially important are:

Winter surprises not only drivers

Spring days do not encourage us to think about the cold. In June it seems that November is a long way off, so we will surely manage to take care of our heating devices. Nothing more misleading. Warmth outside the window puts our alertness to sleep and winter "surprises" us every year. Therefore, at the beginning of spring it is worth modernizing the boiler room and prepare the installation for another busy season.

During the warm months, they allow you to heat your domestic water with free solar energy. Learn more about solar water heating collectors.;;https://salus-controls.eu/2022/06/01/solar-collectors-and-home-heating-systems/;;Are solar panels for water heating a good investment?;;

The sun is an excellent source of energy not only for humans. It is also a source of heat for our homes and offices. To be able to use it, we need the right tools - solar collectors, which are designed to capture the sun's rays from the environment. We can use solar collectors to heat water or to support a basic heating system.

What are solar collectors and how do they work?

Solar collectors are devices with a structure of metal and glass plates ("mirrors") or tubes, which are mounted on the roof of a building. They absorb the energy of solar radiation and convert it into heat. This process is carried out using a heat carrier (solar-heated working medium) - water, glycol, air - which flows through the solar system. The heated working medium is led through a suitable channel to a storage tank in the boiler room, from where, after cooling, it returns to the collectors and the process repeats itself.

The resulting heat goes to domestic installations. We use solar collectors to heat domestic water (most often), to prepare a garden jacuzzi as well as to support central heating. We will point out other advantages of solar collectors in a moment, but first of all it is important to remember that they are a renewable source of thermal energy for a building (RES). They provide support for its energy balance. They simply pay for themselves.

Construction and types of solar collectors for water heating

Each solar collector consists of:

We can choose between flat-plate and tube collectors. Collectors with a flat design (flat absorber) are most popular. This is due to the good value for money. Here the absorber, which is a plate made of copper or aluminum, is covered with a dark layer that absorbs radiation (tempered glass). There are pipes attached to the top of the absorber, through which the heating medium flows. It distributes the generated heat to the solar tank. On the other hand, solar water heating collectors of tubular construction are built of parallel glass tubes, in which the absorber surrounded by vacuum is mounted (vacuum reduces heat loss). Vacuum collectors are more expensive, but, unlike flat collectors, they work efficiently even at lower temperatures.

The advantage of solar collectors is their longevity - they should be operational for at least a dozen years. For this reason, it is worth investing in a solar set made of really solid materials.

Learn about the advantages of solar collectors

Why should you opt for solar collectors for heating water? Let's list the most important benefits of their purchase:

  1. Environmentally friendly acquisition of heat needed to prepare DHW and to support heating of the building. Collectors do not produce exhaust fumes, do not poison the environment with harmful gases. We get environmentally clean heat.

2. Energy efficiency: a well-chosen solar set covers from 70 to even 100% of the demand for heat energy needed to heat domestic water (summer season). This gives real savings, as the consumption of heating fuel and energy decreases significantly on an annual basis.

3. Independence: thermal energy is renewable and free. It allows you to become independent of suppliers of traditional - non-ecological and expensive - energy sources (coal, gas). We incur the expenses only once - during installation.

4. Convenience of use: the solar system is maintenance-free, you do not need to look after it.

5. Reliability: the solar system does not actually break down - it should serve for years.

6. Versatility: solar collectors can be mounted on the roof of any building - single-family, multi-family, but also on apartment blocks.

7. Higher value of the property: a building equipped with modern collectors is worth much more on the real estate market.

Solar collectors vs. photovoltaic panels

When considering the installation of energy-efficient solutions for your house, you may ask yourself if it is better to invest in solar collectors for heating water or in photovoltaic panels? It is also often the case that these two installations are confused with each other. Wrongly, because the way the two technologies work is different. First of all, we get a different end product. As we already know, solar panels convert the energy of the sun's rays into heat, which they transfer to home heating systems. Meanwhile, photovoltaic cells from the sun's rays produce electricity (current), which we can ultimately use in many ways: to heat DHW, to heat the house (e.g. by powering an electric boiler, heat pump) or to run electrical appliances (this will save on electricity bills). Panels, unlike collectors, do not need to be mounted on the roof.

The constantly changing regulations regarding accounting for generated electricity remain a separate issue. It is difficult to predict the final development of events in this topic. But let's remember that forecasts for energy prices are increasingly pessimistic. Therefore, photovoltaics are profitable in almost every scenario. Solar collectors as well. Before making a choice, you just need to do an energy audit and think about the actual demand of your building.

What do you need to watch out for?

The basic rule is that in order to enjoy the benefits of solar collectors we need high sun exposure. If there is no sun the installation will not generate heat. For this reason, when installing, the collectors should face south. They will then absorb most radiation. Unfortunately, in our latitude, insolation can be a problem, because during the winter the solar panels do not have the best conditions for operation. The sun shines briefly, weakly and, in addition, not every day. Unreliable year-round efficiency raises doubts about whether to invest in solar collectors for heating domestic water. Consider, however, that recently summers have been hot and long. There are even tropical temperatures. Winters have mellowed. We are seeing more and more warm months, it can be cheerful from spring to late autumn. All this time we have the chance to use DHW heated by free solar energy. It may not always be hot water, but it will certainly be pleasantly warm and thus sufficient for daily needs.

Some of us are also afraid of overheating the system, that is, generating excess heat during hot, holiday trips. To avoid this, it will be crucial to match the solar set to the building and to choose the right controllers (with alarm, function to turn off the solar pump when the maximum temperature of the tank is reached, heat dump function). Controllers also increase the efficiency of the solar system - they distribute the heat from the solar collectors to get most energy from them.

Solar water heating collectors are a way to save money at home

At a time when we're looking for ways to keep money in our wallets, it is worth considering investing in a solar kit tailored to our needs. It is precisely one such way - an effective, proven one. If we can afford the one-time expense of buying and installing solar panels, rest assured that the cost will pay for itself. The sun produces energy inexhaustibly, free of charge, without any burden on nature. Each month of its use provides an environmental and economic return. Even if the efficiency of solar collectors decreases in winter, it will more than increase in spring and summer. The savings throughout the year will be evident.

We are at the beginning of August – middle of summer. In the second month of vacation, high temperatures are forecast in almost all of Poland, so many of us, if we haven't done it already, are considering buying a backyard pool. And if one opts for a hot tub, one will be able to enjoy a private spa until late autumn. Unfortunately, it is not only the temperatures that are expected to be high soon. Energy price hikes are also getting ready which will force us to save money. In this case, how to heat the water in a pool or a garden Jacuzzi, so as not to go bankrupt on this occasion? Today we point out the most popular options.

How to heat water in the pool - heating systems available on the market

In some climate zones, despite the hot summer days, evenings are sometimes cool. The weather can change from hour to hour. All this makes it difficult to maintain the optimal temperature of pool water for a long time. Optimal, that is one that will be comfortable for us on a given day. After all, no one wants to get a thermal shock from icy temperatures when entering the Jacuzzi. On the other hand waiting for the water to warm up naturally, will take days.

There are several proven systems for heating pool and Jacuzzi water. We can choose from:

We can easily figure out how to heat our pool water to a temperature that suits our needs. But knowing what the options are is one thing and deciding which option to choose is another. The question still remains, which solution will be most cost-effective? Which is the most convenient? Which will come out the cheapest?

Electric water heater

Electric heaters are the most popular option. They allow you to reach the expected temperature in the pool very quickly. Their disadvantage is the high cost of operation - with frequent use, heating the water will come out expensive. Therefore, this solution is used rather for small pools or 3-4 person hot tubs. The mechanism of operation of such heaters is simple - it is based on the work of an electric heater and resembles the heating of water in a room aquarium. The heater heats the water, which flows through the heating device, then the already warm water returns to the bathing area. The flow of water is carried out by the pool's filtration pumps. In short, the heater takes cold water from the pool and heats it. When deciding to heat water by this method, it is essential to control the efficiency of the heater, as it is prone to damage and corrosion (chlorine, calcium in the water). The advantage of heaters is easy installation and low cost of purchase. When choosing an electric heater it is worth choosing a model with an electronic panel that displays the current water temperature. This is convenient and practical. Now that we know how to heat pool water with electric heaters, let's check out other options.

How to heat pool water with a heat exchanger?

Heat exchangers work similarly to heaters, although their mechanism is more complex in design. This method of heating water requires connecting to a domestic central heating boiler. As a result, the warm water that circulates in the pipes of the central heating system transfers heat to the cool pool water. At the same time, there is no mixing of CO water with pool water. It is only a source of heat for the garden swimming pool. The method is easy to use and low-cost, since the heat energy comes from the boiler we use (coal, gas, electric). On the other hand, you need a lot of installation skill and the right (quite expensive) equipment to use this option. Also, the installation of a heat exchanger cannot be carried out everywhere. It is mainly used in larger, masonry pools. We already know how to heat pool water by connecting to the central heating system. So let's see how other devices handle this task.

How to heat pool water with a heat pump?

Electric heat pump is a way that we can successfully call "exclusive". It is very effective and reliable in operation. Heat pumps are increasingly used to heat residential pool water. For now, however, it is not popular, probably because of the high starting price. To start with, it is easier to buy a much cheaper electric heater. The heat pump has to be connected to the domestic water circuit. The cold "pool water" is pumped through the circulation pump to the heat pump, and then, after heating, is returned to the pool/jacuzzi.

The concern may be that the heat pump runs on electricity, which is expensive. However, it doesn't consume much of it and it provides efficient operation for years to come. The great advantage of heat pumps is that they will also heat water at low outdoor temperatures. This allows us to enjoy our garden swimming pool even in bad weather and during the cold months. Heat pumps work quietly and efficiently. They are great for larger pools.

Solar collectors

How to heat pool water with solar collectors? Solar panels capture the sun's heat and transfer it to the water that flows through the device (thanks to a pump that filters the pool water). This method is the most environmentally friendly and the cheapest in comparison to the others. This solution uses a clean renewable energy source - the sun. The installation of collectors should not cause anyone any trouble, so even a person not connected to installation industry can cope with it. The collector does not have to be installed on the roof, it can also be placed on the grass by the pool. The most important principle is that - thanks to its location - it should catch as much sunlight as possible. What’s very important - solar panels can be connected to each other through series installation. The larger the pool we have, the more solar panels we will need for optimal water heating. Wanting to efficiently control the collectors, it is worth considering the purchase of a suitable controller.

Pool heat absorbers

Absorbers work in similar way to collectors but have a simplier structure, cheaper and less complex manufacturing technology; they have no glazing, no casing. Pool water simply flows through the absorbers heated by the sun's rays. This is why they are often chosen instead of collectors. The price of pool absorbers can be up to 3 times lower than that of standard solar panels. On the other hand their efficiency is similar to that of collectors. So if you ask how to heat pool water in an efficient and economical way, pool heat absorbers will be a good answer.

With all the ways discussed, we can extend the use of the outdoor swimming pool in the garden to up to several months.

How to heat pool water using less technological "gadgets"?

Knowing how to heat the water in the pool we can count on a relaxing home spa. However, in order to enjoy it and not go bankrupt, it is equally important to skillfully maintain the achieved temperature. The longer we can keep the "pool water" warm, the less we will pay to reheat it. For this purpose, it is worth using solar film. Such a film is relatively light and malleable (in large pools it is rolled up on a "coil"). It floats freely on the surface of the pool, so it is easy to cover and uncover. Thanks to solar film we:

We can cover smaller, portable baths with foam covers so that they don't lose their precious warmth in colder days. We should also remember about the importance of keeping the water clean. This is important not only for hygienic or health reasons but also for economic reasons. Once dirty, it will be necessary to change the water in the pool or Jacuzzi. And because of that, reheating of water will also have to take place.

What else can you protect your garden pool with?

1. pool canopies

2. covers on special guides

3. pool blinds

4. safety net (spring mechanism)

5. winter cover made of non-freezing plastic

How to heat pool water without spending money?

As an interesting fact, it is worth mentioning that the ingenuity of garden pool users knows no bounds. In social media (for example on the YouTube platform) some of them show how to heat pool water practically for free. In order not to incur the cost of buying any of the heating equipment described in this article, users create their own "tips". One of them is to construct a "heater" with their own hands, by laying several garden hoses on black plastic sheeting, into which cold water from the pool is pumped. The intake of water is done with a thick plastic pipe, through a small pump connected to a rubber hose (such as from a cooler). Using a quick coupler, this hose connects to the garden hoses, which are heated by free solar energy. Thus, pleasantly warm water is returning to the pool. It flows there with the last element of this amateur "heater" - with a garden hose. On a really hot day, this unusual method makes it possible to get a temperature as much as 10℃ higher at the outlet.

Other DIY suggestions show how to create a "heater" using floor heating hoses and a circulation pump. But before deciding to build such ingenious constructions, let's check their actual effectiveness. It's a good idea to ask people who have already made something similar, go to online forums dedicated to this topic and create an overview cost estimate.

Heat pump - how to control it safely?

A heat pump is an efficient and ecological heating device. Its great advantage is that it uses thermal energy obtained from renewable sources (air, ground, ground water In addition, the heat pump emits no greenhouse gases, operates maintenance-free and consumes little energy. So it is hardly surprising that more and more people decide to heat their homes with heat pumps. There is still the issue of controlling the heat produced by it. It is believed that zone control increases its failure rate. But is this true? How to safely control a heat pump to achieve the right temperature in the rooms?

How does a heat pump work?

The device pumps heat from a lower source to an upper source, collecting electricity in the process. The bottom source is where the working medium is taken from; water, ground, or air, and this is what determines the type of pump. In air pumps, the lower source will be the air, in water pumps - groundwater, in groundwater pumps the energy is taken directly from the ground. The upper source is nothing but the heating system of the house.

A heat pump consists of:

- an exchanger that extracts heat from the environment (for example, an air source heat pump sucks in the air)

- a compressor that circulates the heat internally increases the temperature and pressure of the fluid taken from the lower source - this fluid is condensed and transferred to the...

- exchanger and expansion valve, which transfers heat to the upper source (i.e. to the home system) and closes the circuit.

In summary, a heat pump works on the principle of thermodynamic conversion. It forces the heat from the ground, water, or air into heated rooms or even into a DHW system. Such pumps can successfully power radiators, underfloor heating and fan coil units.

Zone control vs heat pump

In a simple way, zone control involves installing thermostats in each room, which allows you to adjust the temperature in your home according to your needs.

Meanwhile, a heat pump, due to its mechanism of operation, has a rather long start-up time. Therefore, it needs time to heat up the medium (e.g. air) taken from the environment.

Meanwhile, a heat pump, due to its mechanism of operation, has a rather long start-up time. Therefore, it needs time to heat up the medium (e.g. air) taken from the environment.

This has obvious disadvantages when we want to apply zone control which is comfortable for the household members. For example, if you want to heat a small room (e.g. bathroom) using the underfloor heating system, you have to switch the heat pump on and off in a short period of time. And this, of course, can cause it to fail. That's why we don't control the heat pump directly, but the water distribution from the buffer, which stores the heat it produces. This allows you to enjoy all the benefits of zone-based home control.

Benefits of heating control

Zone control of each type of heating avoids overheating conditions and reduces energy losses. As a result, you use as much heat as you actually need - neither more nor less. This saves money and protects the environment.

  1. Create warm zones: separate temperature control for each room
  2. Avoiding overheating and undercooling: temperature adapted to the function of the room
  3. Optimum energy consumption
  4. Saving heating fuel and money
  5. Protection of the environment
  6. Comfort and convenience


Zone control is necessary. However, to be efficient and safe for the heat pump, the heating system should be equipped with a proper buffer tank - the heat stored in it is distributed to heating loops. Controllers and thermostats dose the heat according to the settings of the household. This makes it possible to automate the distribution of the heating medium and maintain the selected temperature in the house. The control takes place at the level of the buffer, not the heat pump. In this case, temperature management becomes as convenient and efficient as with gas or electric heating.

Self-regulating actuator - why is it worth it?

A well-adjusted hydraulic heating system ensures the ideal temperature in the household rooms. It guarantees the feeling of comfort, has a positive influence on our health, and generates savings. A tool that offers a proper setting for underfloor heating system operation is THB self-regulating actuator.

What is a THB self-regulating actuator and how does it work?

The THB23030/THB2430 actuator is a modern, manifold-mounted self-regulating device for surface heating systems. Its precision is incomparable to others: by constantly measuring at the beginning and end of the heating loop, it maintains the optimum temperature difference and adapts the water flow to the building's needs.


At the supply and return of the corresponding underfloor heating loop, the THB actuator has contact sensors that measure the temperature and automatically adjust the actuator to maintain the correct supply/return temperature difference (ΔT).

Why is it important?

It is estimated that about 90% of central heating installations are not hydraulically adjusted. This means that the distribution of the heating liquid stream is incorrect - the house is unevenly heated (overheating/underheating also within one zone). This results in energy losses, higher bills and inappropriate interior microclimate, which causes worse mood of household members.

Why does this happen?

There are many reasons (more on that below), but one of the most common is carelessness at the installation stage. Due to a large number of tasks and a fast working pace which leaves little time for precision, some installers do not pay proper attention to the adjustment of the underfloor heating they are setting up. Unfortunately, this results in the future low efficiency of the heating system. The THB self-regulating actuator is the solution to this problem, because by using it, you gain ideal thermal comfort with minimal energy consumption.

Hydraulic balancing (hydraulic calibration)

Hydraulic balancing of the heating system allows an even distribution of the heat medium (heating fluid), in accordance with the building design. This eliminates unwanted overflows and underflows, which reduces heating costs. The hydraulically balanced system is based on real fluid flows. Even the longest underfloor heating loops are provided with an adequate flow rate - there is no cooling of the room. And the shortest loops are not exposed to excessive flow rates - no overheating is taking place. All loops have the right heating medium flow rate, so the system is comfortable to use and energy-efficient. Hydraulic calibration is very important in buildings that are being thermally upgraded and in low-parameter installations powered by heat pumps or condensing boilers.

Factors that disturb the hydraulic balance of a central heating system

Why are most installations poorly hydraulically balanced? This is caused by many factors that are not always up to you. The most common are:

Your benefits when purchasing a THB

First, quick installation (only 3 steps). You just need to install the actuator on the manifold, and connect the sensors and power supply.

Second, convenience and time-saving. No need to regularly check and tune the system - the actuator does it for you.

Third, easy fit; THBs can be used on manifolds with and without flow meters (rotameters). They fit the most common thread size M30x1.5. What is important, when you decide on a manifold with flow meters, you have to expect a higher price of the device, but without a guarantee that the system will always work reliably. Rotameters can be problematic; after some time of use, they wear out and stop working properly. Using THB actuators this risk disappears because you do not need flow meters at all. You can buy a cheaper manifold and ensure you have the best-regulated heating system. This is really a big economic and functional advantage.

You get efficient heating. The underfloor heating works efficiently with different loop lengths and even with changing interior design, and gives an even temperature throughout the zone.

Other advantages of THB

The effectiveness of the device has been confirmed by technical tests. The iTG Dresden[1] confirmed that the THB self-regulating actuator correctly balances an underfloor heating system. In cooperation with iTG Dresden we tested and improved our actuator.

REMEMBER: Reduction of energy consumption after hydraulic balancing is about 10 - 20 kWh/m2 per year, which means savings of around 220 EUR for a house of 100 m2. The benefits of buying an actuator are therefore measurable, not hypothetical.

Which model to choose?;;https://salus-controls.eu/2022/04/01/thermoelectric-actuator/;;Thermoelectric actuator;;

Efficient heating of buildings has become a challenge for investors. It is no longer just about keeping people warm. There is much more than that: Adjustment of the temperature to the function of the room, low consumption of heating fuel, long service life of the system and convenient operation. All of this results in money savings, environmental protection and a better quality of life. Our everyday comfort, the costs of operating the house and the ecological future of the planet depend on the heating system installed in the building. There are a lot of tasks to be performed ... Therefore, modern heating installations must work efficiently. To make it possible, they should be equipped with durable and safe elements controlling the flow of the heating medium. One of such elements is a thermoelectric actuator.

What is a thermoelectric actuator?

Thermoelectric actuator is designed to control heating installation - both underfloor and radiator. It makes it possible to open and close the flow of the heating medium (e.g. hot water) in a loop, ensuring control over the temperature in the building. It can be used both on valve inserts at the radiators and in radiator and floor manifolds. However, it should be remembered that some actuator models are suitable only for specific valve inserts (such information should be found in the instructions or product card). Thermoelectric actuators are also used to control heat in boilers and DHW controllers. In this case, external controllers should be used. Modern actuators cooperate with room thermostats (temperature thermostats) and wiring centers. To sum up, thermoelectric actuators are installed mainly to control the operation of individual heating systems.

How does a thermoelectric actuator work?

The principle of operation is not complicated. The basic function of the thermoelectric actuator is to press and release the valve stem of the heating system. Basically, it looks like this (example for NC actuators): when no control voltage is applied (so-called de-energized state), the actuator presses the valve stem - the valve is closed (the heating medium does not flow through the system, it does not heat). When the control voltage appears, the actuator releases the stem - the valve opens (the heating medium flows through the system and heats the room). This control mechanism, although simple, is crucial for efficient heating operation.

Which thermoelectric actuator to choose?

It is easy to see that the reliable operation of actuators is the key to the correct and efficient operation of the entire heating control system. When choosing thermoelectric actuators for your home (or for a client's home), you need to pay attention to several issues.

Firstly, the actuators must be compatible with the rest of the heating system. The first thing to do is to check whether they fit the valves. An important parameter here is the so-called actuator stroke (given in mm). It decides which thermostatic inserts (with which manifolds) the actuator is compatible. The larger the stroke, the greater the certainty that the device will work with a given insert. It will be able to open the insert (valve) enough to ensure the flow, and close it so that there is no flow at 100%.

Secondly, the type of actuator in terms of voltage-free state. On the market we can buy NO actuators - normally opened (when there is no voltage, the valve is open, the voltage closes the valve) or (and there are more of them) NC actuators - normally closed. Here, in the voltage-free state, the valve is closed, and the voltage opens the valve and starts heating.

Thirdly - supported voltage. Most actuators are adapted for voltage of 230V, but before buying you should check it. Some manufacturers, including SALUS Controls, also offer models powered by 24V.

Fourth, the operating power consumption: it should not exceed 5 W. It is better if it is lower.

Fifth, opening time: remember that actuators have a delayed action. The best quality devices start in less than 3 minutes.

Sixth, the status indicator. It seems to be nothing essential, but it makes a difference. Thanks to it we know whether the valve is open or closed at the moment.

And finally, seventh, additional assembly facilities. It is worth noting whether the product you are interested in has a first open function. If so, during the first assembly the device is in the open position, which enables the flow of fluid and performing a pressure test without removing the actuator. This makes installation easier.

The perfect thermoelectric actuator for your underfloor heating system

Our actuators are one of the most valued devices on the market, controlling the heating flow in the circuits of surface (floor) installation. They are durable, safe, easy to operate. They have small dimensions, consume little power (only 2W) and the first installation is facilitated by the mentioned first open function. Their other advantages are fast opening time (about 2 minutes) and 4-mm stroke. With a stroke of 4 mm, the actuator will work well with practically every thermostatic insert available in stores. SALUS Controls underfloor heating manifold actuators also have a clearly visible element indicating the status of the device; open or close.
