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.

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.

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.

Today we write about energy-efficient devices that work in a smart home.;;https://salus-controls.eu/2022/05/19/smart-solutions-for-your-home/;;Smart solutions for your home;;

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.

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.

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.

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.

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.

Why should you decide to do it? ;;https://salus-controls.eu/2022/03/30/what-type-of-heating-to-choose-for-the-bathroom/;;What type of heating to choose for the bathroom?;;

Choosing the type of heating for the bathroom is crucial for the comfort of the household. What kind of installation should you decide on: a modern underfloor heating system or a traditional radiator? After all, both a warm floor and a hot radiator are very useful solutions in any bathroom. Many of us, therefore, decide on a mixed installation. How to effectively combine these two heating systems in a small room? It doesn't have to be difficult, as long as we approach the topic wisely. Heating for the bathroom cannot be a coincidence.

Bathroom is a special place in every home. We value privacy, we want to feel safe, cozy, and above all - free. When arranging "home spa space", we also want it to be functional and adapted to intimate circumstances. In the bathroom, we often stay naked, barefoot, regenerate strength. That is why it is so important that we are simply warm.

Heating for the bathroom in a house with underfloor heating

When choosing the ideal heating for the bathroom, we often want to be able to heat the bathroom and use a ladder radiator as a laundry dryer. Underfloor heating, although it provides warmth at the feet, does not give us this opportunity. How to combine underfloor heating with radiator heating in the bathroom, if our house is entirely based on the UFH?

The first method

The easiest way to do this is to connect a ladder radiator to the underfloor heating system. It can be done by creating an additional loop and connecting it to the UFH manifold. It can be the most intuitive and simplest way to connect the radiator and underfloor heating in a small room. Unfortunately, as for the simplest method, it is not ideal. The disadvantage of this solution is constantly low radiator temperature which results from low supply temperatures. Remember that underfloor heating is a low-temperature heating system.

The floor temperature should not exceed 28ºC in living rooms and 35ºC in corridors or in bathrooms. What is the conclusion? When the heating medium from the UFH system flows into the radiator, the radiator will be at most warm, if not less. So it won't heat the bathroom during a bath. It won't play the role of a dryer for laundry - and that's what we care about. For this reason, UFH is useful as basic heating only in buildings with decent thermal insulation.

The second method

The second, more sensible solution, is to mount a heater to the radiator connected to the underfloor. However, do not do it in a random place! For safety reasons, the heater must be far away from the sink, bathtub, bidet, etc. When you start the heater, you have to cut off the radiator from the UFH system.

Otherwise the heat produced by the heater will flow from the radiator to other parts of the installation. So to speak, it will "melt into the floor". When we cut off the radiator from the underfloor system, the heat will stay in the bathroom and in the ladder radiator. With this solution, do not forget to reduce the excess pressure that will naturally arise when heating water. Therefore, do not close the second shut-off valve. Heating for the bathroom must be planned in accordance with all safety requirements.

However, if we do not have the opportunity to install a traditional heater in our bathroom, we can choose an electric heater. It has a lot of advantages. It is easy to operate and without difficulty adjust the power of work.

This will allow us to set a higher supply temperature at the necessary time and avoid "combining" in the water installation. The predictable disadvantage of this method is ... price. Operating an electric heater is not one of the cheapest. For this reason, it is necessary to invest in a heating control system. A wisely chosen temperature thermostat will allow you to maintain thermal comfort with minimal consumption of heating energy. Remember that an electric heater should be placed away from any sources of humidity.

Third method

The most effective (and most time-consuming) is to create separate heating circuits, which will work independently of each other. That is: a separate circuit for a radiator, a separate circuit for the underfloor heating. Thanks to that, low supply temperature of the underfloor circuit is not a problem at all. The radiator supply temperature will be independent from it.

Heating for a bathroom in a house with radiator heating

Let's imagine.

The basic heating system in our house is radiator heating. During the construction of the house, we did not plan to use a water underfloor in the bathroom.

.The problem of not having a laundry dryer is eliminated. We have a ladder radiator and room radiators in a package. High supply temperature of radiators will easily allow you to heat up the bathroom and the whole house according to the needs of even the biggest snowbird. But you will not benefit from the comfort of a warm underfloor, which for many people is priceless.

We quickly get used to good solutions. If we try it, heating the floor will most likely become a matter of course for us. What is important, a warm floor in the bathroom also has a hygienic function; the floor dries faster, does not accumulate dirt, no stains form on tiles and no fungus develops. If we want to enjoy a warm floor in an apartment with radiator heating but we are not planning a general renovation, we are not without a solution.

In such a situation it is worth considering the use of electric heating mats. A great advantage of this option is the possibility to quickly heat up the floor to a pleasant "warmth at your feet". Even outside the heating season, i.e. when the central heating is not working. We will appreciate this pleasant experience both in early spring and late autumn, when the heat from the floor spreads over our body after a bath. However, in order to minimize the operating costs of heating mats, you need to think about a thermostat with a precise control algorithm, which will ensure not only lower bills, but also greater comfort of the "home spa".

We hope that the answer to the question "What type of heating to choose for the bathroom??" is now much easier.

Traditional head vs intelligent head

Thermostatic heads (sometimes confusingly called thermostats) are used to control radiator heating. They allow individual control of temperature in interiors and help to maintain it at a level suitable for household members. Simply put, the job of the heads is to manage the flow; admitting and shutting off the heating element (hot water) for room heaters. They are mounted on a valve insert.

A traditional manual heating head - that is a head on which you manually set the heating levels, usually marked with numbers from 0 (⁕) to 5 - regulates the amount of heat supplied to the room (to the radiator in the room) in an approximate way. The scheme is usually as follows: when you leave the house and want to save on consumption, set the head to level 0. When you need to warm up a cooled room, for a short time set 5. During everyday use, we usually choose 3, on colder days, 4. When you want to quickly cool down a strongly heated room, turn the head e.g. to level 2.

This, of course, does not allow for precise control, nor does it ensure complete comfort or high savings. Overheating and overcooling are elements that need to be accepted. A much more precise and economical solution is a modern, INTELLIGENT ELECTRONIC THERMOSTATIC RADIATOR HEAD which regulates the amount of heat supplied so that the rooms are not overheated or cooled down. This allows you to avoid expensive heat losses and maintain a comfortable temperature in your home.

The electronic radiator head owes its accuracy to the modulation method. This means that the valve can be gradually closed or opened, depending on the correlation between the current room temperature constantly measured by the thermostat and the temperature set by the household members.

Intelligent electronic thermostatic radiator heads by SALUS Controls

SALUS Controls company offers electronic radiator heads with two sizes of thread:

- TRV28RFM (M28 x 1.5)

- TRV10RFM (M30 x 1.5)

as well as the model:

- TRV10RAM with allen key mounting (mounting on Danfoss RA valve)

The devices are compatible with the majority of thermostatic valves available on the market, however, before mounting, it is necessary to check whether the valve is suitable for use with the chosen TRV radiator head. When choosing a product for a radiator already equipped with a valve, always check the thread dimensions. If there are discrepancies in dimensions, please contact us or your installer to discuss the possibility of replacing the valve with one that works with the radiator head.

A great advantage of SALUS Controls intelligent radiator heads is pairing them with room thermostats. This allows you to set heating schedules that adjust the temperature to the time of day and the rhythm of life of residents. In addition, the operation of the device is much easier here - you do not have to manually set the operating modes on a small-sized radiator head.

Intelligent thermostatic radiator heads are therefore great replacements for manual devices - they automate the control of radiator heating and optimize the operation of the installation. However, it is important to note that in order to work properly, they must be correctly synchronized with the wireless temperature thermostat using the CO10RF coordinating unit or the UGE600 gateway (products sold separately).

TRV radiator head paired with SALUS Smart Home series temperature thermostats provides a sense of warmth throughout the room, not just by the radiator. What is important, one thermostat can be paired with as many as 6 heads in the same heating zone (i.e. in one room), which allows for ideal heating of a really large area (e.g. living room combined with kitchen).

In SALUS Smart Home system the TRV head can work in the following modes:

You only need to decide on one ZigBee network coordinator (either CO10RF or UGE600).

Additional features of the TRV

Anti-freeze protection

Anti-freeze mode is typically used during long absences from home (trips). The antifreeze protection temperature value is set directly on the thermostat. The function is activated when the room temperature drops below the value set on the thermostat. Recall: the device maintains the set temperature value provided that it communicates with the thermostat.

Open window function

The TRV checks the rate of temperature drop in the room in which it is installed. If the drop is fast, the device assumes that a window has been opened and closes, cutting off the heating medium supply, while a normal thermostatic head would open to make the radiator warmer. This function is active provided that the head communicates correctly with the thermostat, is in automatic mode, and the batteries are not discharged.

Limescale protection

Do not leave the valve idle for a long time as this can cause limescale build up on it. SALUS Controls TRV heads have a limescale protection function. They are activated automatically once every 14 days - if no valve movement is detected during that time. The protection works if the radiator head is in automatic or manual mode.

Your benefits from purchasing SALUS Controls thermostatic radiator heads

- saving money (e.g. by automatically lowering the temperature at certain times on selected radiators)

- ease of installation: the radiator head automatically adjusts to the valve insert

- safety of use: the product has a button lock

- convenience: no need to adjust the temperature manually

- thermal comfort at home

TIP: to have the best control over the interaction between the thermostat and the heating device in the system with TRV heads, we also recommend using the RX10RF control module, which forces the heat source

to start depending on the heat demand signal sent by the thermostat. We encourage you to watch videos on our YouTube channel instructing how to install a TRV radiator head.

Check what you are breathing.;;https://salus-controls.eu/2022/03/01/composition-of-inhaled-and-exhaled-air/;;Composition of inhaled and exhaled air;;

For us to feel good, the air we breathe must have the proper composition. The components of air are crucial to respiratory health. Unfortunately, air pollution is one of the biggest civilization plagues we have to face. Remember that even low concentrations of inhalant pollutants can reduce the quality and length of our lives.

What is air?

In short, air is the mixture of gases and aerosols that forms the Earth's atmosphere. This has changed over the centuries, but currently the concentration of air elements remains relatively constant. In the atmospheric air we can distinguish between solid particles and those whose presence varies depending on weather, environmental and civilization factors. We are talking for example about water vapour, carbon dioxide as well as the infamous sulphur dioxide (SO2) which is a suffocating and highly toxic gas. Its concentration depends on geographical location, industrial development, season of the year. It is hard not to mention here that the main source of SO2 emission into the atmosphere is the burning of fossil fuels.

Composition of air

Pure atmospheric air contains elements such as nitrogen, oxygen, argon and carbon dioxide. The most important gas is, of course, oxygen, which is involved in all physiological processes in the human body. Of course, it's not just us humans who need cellular respiration. Without oxygen, animals and plants would not survive either. In the air, we also find further chemical compounds: hydrogen, neon, helium, methane, krypton, xenon, ozone, iodine, mineral and organic suspended solids, such as plant spores, as well as poisonous gases and dusts.

What shouldn't be in our air?

The matter seems clear, but let's list those components of the air that threaten our health. These are mainly industrial, economic and mineral pollution (dust, soot), and harmful products of oxidation of various combustible materials. Fuel combustion is the primary source of atmospheric contamination. As a result, we inhale:

Fine dusts are very dangerous and equally insidious. They have such a small particle size that the human eye is not able to see it (diameter less than 2.5 micrometers). Therefore it is worth remembering that the average annual concentration of fine dust is 10 μg/m3 (micrograms per cubic meter). Let's be careful during grilling season too! It's hard to defend ourselves against harmful air constituents - after all, we won't hold our breath. However, it's always a good idea to invest in home dust sensors, but also check the automatic measurement data available on many websites. They give you the current composition of the air, updated every hour.

Composition of inhaled and exhaled air

The percentage composition of gases in inhaled air looks like this: 78% nitrogen, 21% oxygen, 0.04% carbon dioxide, and 1% other gases. The percentage distribution of elements in exhaled air is already slightly different as the value of carbon dioxide increases: 78% nitrogen, 17% oxygen, as much as 4% carbon dioxide, and 1% of the other gases. Let us recall that the air we breathe every day is full of pathological substances, i.e. substances that should not be there. These are mainly pollutants, originating from human activity: chimneys, car exhausts, factories (see above). Dusts and harmful gases spread destruction in the tissues of living organisms. What is important, toxic substances from the outside are also transmitted indoors, so in fact it is impossible to protect against them 100%. When we inhale smog and exhaust fumes, we damage the respiratory system (especially the lungs and bronchi), the circulatory system (heart, arteries), and the nervous system (cells, brain).

Contaminated air leads to the formation of cancer, hypertension, conjunctivitis, asthma and other serious disorders. It also has a disastrous effect on the health of pregnant women, on foetal development (birth defects). Therefore, air quality is not a topic for ecologists, but an important issue for each of us. It is a matter of life and death.

How to check the air composition?

For this purpose, specialized room and outdoor measuring devices are used. The usefulness of these devices is enormous because it gives a lot of knowledge about what air components and in what amounts get into our lungs.

An interesting ecological action is also the campaign of the Polish Smog Alert under the slogan: See what you are breathing. It consists in the fact that selected towns - the most threatened by the influence of smog - will appear so called artificial lungs. It is a mobile two-meter installation, which travels around the country. It indicates the level of air pollution in the most illustrative way - mobile lungs change color over time. At first they are white, after a few days they become gray, graphite, even black. The lungs are made of translucent material. Back fans pass air through them, imitating human breathing. Through this demonstration, viewers see how polluted their towns and villages are.

What can be done to improve the quality and composition of the air we breathe?

Lighting dimmer is one of the most popular devices working in a smart home. Allows you to adjust the brightness of the room to the time of day and what mood we want to create at the moment. Thanks to it, the house becomes universal, better suited to the user's needs. Dimmers have a cost-saving function, they also allow to regenerate tired eyesight.

How does a light dimmer work?

Modern light dimmers are devices that work with advanced electronics. It is a new version of this type of product, created with the use of modern technologies. In the past, dimmers were potentiometers operated by a knob. With their help, we could manually adjust the parameters of the electricity supplying the bulb. We can still buy many dimmers of this type but modern models are ahead of them in terms of precision of operation and convenience of use (we do it remotely). In modern dimmers, the role of a potentiometer is taken over by so-called printed circuits, i.e. specially prepared boards on which a pattern of tracks is applied to form an electronic circuit. These boards are the heart of the device.

New solutions for light control are constantly appearing on the market. They use for example radio waves or infrared. Dimmers can cooperate with other elements of the intelligent house (e.g. air conditioning, heating). Remember, however, that with a dimmer light rarely achieves 100% of its power. It all depends on what kind of dimmer you decide on (its parameters), but most often it will be around 80-90% of the bulb's power. If we need a lot of light to work, let's install a fluorescent lamp of the highest possible power. When the situation requires it, we will achieve the necessary brightness in the room.

Types of dimmers

Light switches with adjustable intensity can be divided into three main types:

Remote: control via remote control or mobile app (also via the internet)

Touch: dimming and brightening by touching the panel for a long time

Manual: traditional potentiometer principle (knob, dial)

When is a light dimmer useful?

Its most important advantage is that we can adjust the light intensity according to the circumstances. Light intensity is nothing but the density of the light stream, which affects the sharpness and accuracy of vision. Adequate room brightness determines the functionality of the home. When working or studying we need more light.

When we want to relax, we choose toned-down, moody lighting to make our eyes feel comfortable. By using a dimmer, we can quickly create the atmosphere we need in the room. It is also a solution for minimalists and people who care about the multifunctionality of a room. We do not need different lamps to achieve different effects. All you need is one, operated by a lighting controller with a dimmer function. It is hard to deny that it is primarily convenient and economical on a daily basis.

Which light dimmer for which light source?

The technical parameters of light controllers differ depending on the type of lighting in which we want to use it. Before you decide to buy one, it is necessary to determine what kind of lamp will be operated by our dimmer (incandescent, halogen, or maybe led). This is important because a wrong choice may cost us a failure of the device. Remember also that not all bulbs can be dimmed. Such information should be placed on the packaging.

Every light dimmer available on the supermarket shelf has a specific load (watts) in which it works properly. If the bulb has less power than declared on the dimmer, the light will blink (if we will have light at all). On the other hand, if the parameters of the bulb are too high for the dimmer, the failure of the fuse may happen.

Old-type bulbs (voltage 230V) are usually perfectly compatible with light dimmers, but it is difficult to talk about the economic consumption of electricity. It is rather about the convenience of light reduction in situations that do not require "full illumination". Decorative bulbs, regardless of their type, must be dimmable to work with a device. LED bulbs must also have this function, but require modern electronic dimmers that control the current supply with the greatest accuracy. Otherwise, the diodes will lose their life prematurely. Energy-saving fluorescent lamps must be dimmable. 230V halogen lamps are compatible with a dimmer (importantly, a dimmer significantly increases the life of halogens).

RC and RL dimmer - what are these symbols?

RC - dimming by switching off on a falling edge. They work with incandescent bulbs, 230V halogens, 12V halogens, fluorescent lamps, LEDs (they dim the light up to 40%).

RL - dimming by delayed activation on the rising edge. They work with incandescent, halogen bulbs and some LEDs (they have a larger dimming range, allowing for minimal room lighting).

Light control means savings and better health

Choosing lighting with the right intensity is a great advantage.

First, dimmers give us only the light we need at a given moment. Thanks to them, we can freely light up or darken the room. Depending on what we do or how we feel. They consume a minimal amount of energy. Thanks to the fact that they allow you to dim the light, they reduce electricity consumption. As a result, we pay lower bills.
Secondly, light dimmers help protect your eyesight and improve your mood. Too little or too high an intensity of light is harmful to the eyes. It causes migraines in particularly sensitive people, distracts - simply makes them tired. The possibility of afternoon or evening light dimming has a soothing effect on the nervous system, creates a cozy atmosphere, and promotes relaxation.

The heating surface can be either the floor or the walls of the building. It ensures proper temperature distribution in the rooms. That is why surface heating is considered to be economical and comfortable. The most important feature of surface heating, including underfloor heating, is high thermal inertia. Houses in which this type of heating has been installed are characterized by a long time of warming up and cooling down. Therefore it is crucial to select an automatic control system for individual loops of underfloor heating, which will automate and optimize the operation of the whole system. An appropriate SALUS thermostat for underfloor heating ensures savings and well-being.

Advantages of underfloor heating

Underfloor heating provides the luxury of equally distributed heat in the house. At the same time, it eliminates areas of overheating and underheating, which occur in radiator heating. In floor heating, contrary to convection heating (radiators), heat is distributed by radiation.

The design of this system makes it invisible, as the structure is completely hidden on the floor. However, this is another reason why it is so important to control the underfloor with a room thermostat. These devices increase their energy efficiency and performance. A well-chosen thermostat for the underfloor heating system will regulate the temperature. It benefits translate to the environment, household budget, and health of the users.
