Underfloor heating is a system for heating air in a room, in which the heating element is the flooring.
Such a coating can be the only and main heating system or act as an auxiliary heating device for an apartment or a residential building.
The most popular are two types of space heating in this way:
- water heating;
- electric heating.
REFERENCE! The coolant in the water system is water, antifreeze or a similar solution. In electrical systems, the air is heated by the operation of connected infrared film, carbon rods, or similar electrical equipment.

The characteristic feature of a warm surface is that heated air rises from below. Thus, at the level of a person's feet, the air warming rate is slightly higher than with a conventional heating system.

This approach to space heating ensures a comfortable stay for people in him. Moreover, at the same time the optimal level of air humidity is maintained.
Temperature standards in living quarters
To ensure the most comfortable thermal conditions in your home, you should know what air temperature is optimal for human life. And also how to properly adjust it in case of using the "warm floor" system.
So, for a comfortable stay in the room, it is enough to warm up the air to 22-24 ° С. Wherein coating heating rate should be slightly higher and vary within from 26 to 35 ° С. Exactly these parameters are set in the building codes and regulations.
A more accurate indicator of the heating of the coating, which will mean the optimal level of heat in your home, depends on the following factors.
- Whether people are constantly in a particular room.
IMPORTANT! A bathroom or a toilet requires a floor temperature several degrees higher than in the living room.
- From the type of coverage.
- From the heat loss of a particular building.

What should be the temperature of the water floor under the tiles
As for the water-heated floor, it is obvious that the temperature of the water or other medium in the pipes should be significantly higher than the coating itself. This will help ensure sufficient heating of the indoor air.
IMPORTANT! The optimum temperature of the water coming from the boiler should vary between 30 and 55 ° C. In this case, more accurate indicators are calculated individually, depending on the characteristics of the room.
Experts note that in a large number of cases, it will be enough to heat the water in pipes up to 40 ° С.
REFERENCE! The temperature of the surface covered with tiles or tiles should be 26 ° C. This is exactly the indicator recorded in the European standard.
Ways to adjust the temperature of the water floor
There are various ways to control the heating level of coatings.
- Manual;
- Individual, when separate indicators are set for different rooms;
- Comprehensive that integrates different ways throughout the entire home.
Modern technology suggests the use of thermostats, the use of which only requires setting the desired temperature in the system, and its adjustment will occur automatically.
