In the water heating system, the main heating element is a concrete plate. It is thermally isolated. Inside the plate, pipes for hot water circulation are mounted. But in general, the very design of the floor is such. On a cement-sand screed, which should be perfectly flat laid out a flooring with thermal insulation containing an aluminum film. The heat -insulating film is necessarily laid and along the walls. Such installation does not allow heat to go through the walls and the base of the floor. After the heat -insulating film, the pipes are installed using special fasteners and then everything is poured with a solution of cement. At the end, the tile is laid out on this surface, the carpet or parquet is laid. Such a heating system works to count the pump and distributors of the heating contours. Another equipment is equipped with a control system – servo drives, valves, thermostats.
In the system of warm floors, the water temperature should not be more than 55 ° C. Because at high temperatures, for example, 90C °, the temperature of the floor itself will reach 40-50 s °, and this is not comfortable for the legs. This temperature can cause cracks in a cement screed (especially if a cheap sand concrete was used, which is intended for other purposes), and the tile itself may lag behind. The optimum temperature for living rooms is 29 C °, and for bathrooms 33C °. The flow rate of water should be no more than 1 m // m2 . For this, boilers with a temperature supply of 90 ° C are suitable. But usually in systems with central heating the temperature of the water above 50-55 s °. For this reason, it is necessary to install three -way TERMOMOMOMICAL taps, mixing taps or special regulatory equipment.
There is an opinion that water warm floors can cause a weak pressure of water in a multi -storey building. And they suffer from this, as a rule, neighbors below the floor. But this can happen mainly in old houses and, then only where the gravitational, t, is still used. e. Summary water supply system. As a rule, this happens due to the miscalculations in the slopes and the diameter of the pipes. And one more important fact. The water floor of the warm floor is closed and circulation is carried out using the pump.
So the neighbors cannot say that they do not have enough water. But still, do not forget that before the installation of such gender in multi-storey buildings, permission from the relevant authorities should be obtained.
