Heating without batteries only due to underfloor heating (real feedback from the owner with expenses)
Many do not want to spoil the view with heating batteries, pipes running along the perimeter of the rooms. Therefore, they decide to heat the house with the help of modern technologies - only due to the warm floor. Underfloor heating was originally intended for underfloor heating. Can a warm floor be used as the only source of heat or not?
Everything is possible, but there are many factors to consider. Many builders are now convincing customers to save on radiators and make heating using underfloor heating.
The more thoughtfully the house is insulated, the less heat loss and the more likely it is that the warm floor will replace radiators.
According to SP 60. 13330.2012 and p. 6.5.12, the floor surface temperature should be 31 g. if the premises are used for temporary stay of people (bathroom, corridor, pantry, etc.). And 26 degrees for permanent residence rooms.
From the point of view of comfort, the optimum floor temperature for the feet should be no higher than 31 degrees. Consider what kind of coverage will be. Parquet / laminate manufacturers warn that the surface of their finishing material should not be heated more than 27 degrees in order not to dry out.
Therefore, if you do not have parquet or laminate, then the floor (according to European standards) can be heated up to 29 grams. for residential premises.
Ceramic tiles tolerate heat / cold well.
It is environmentally friendly and most suitable for a warm floor. Keep in mind that a matte, uneven surface of a tile gives off less heat (by 30%) than a smooth one. Modern self-leveling floors are also good.
If you lay 3cm penoplex. for underfloor heating, you can save 40% more heat.
It is not necessary to attach the penoplex to the base. It will still be zipped. According to many reviews, such insulation combined with a warm floor is an ideal solution. The screed is no more than 7 cm so that the floors warm up well.
Do not forget about the thickness of the floor heating cake. There will be problems with interior doors. If, according to the standard, the openings are 210-215 cm. from the floor, then after installing the warm floor, the height of the doorway decreases and becomes about 2 m. Solution: increase the height of the opening (hammer the wall) or change (trim) the doors themselves.
There is another common mistake for a multi-storey building. This is a staircase. When the height of the warm floor is not taken into account. The first step (height) may be less.
Review from Alexander
A two-storey house from a gas block (30 cm.). House area 100 sq. m. The second floor is not heated (heating is provided by the first floor).
On the ceiling of the second floor - 25 cm mineral wool. Heating - electric boiler. Very comfortable even for the bedroom. Consumption - 2800 kW per month. The floor temperature on the first floor is 30 degrees. The windows do not fog up, there is no condensation. If you insulate the walls of the house with 10 cm mineral wool, then this method will help to save well on heating.
