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.
