Warm floor is comfort and convenience, feet are warm, head is cold. Most of the owners of these communications will attest to this. Except for a small number of people who have their own point of view on this issue. If funds are available, why not make this dream come true. The main thing is to find a competent specialist.
Such proposals were received by me, but naturally I refused, because I understand what problems the owners of this convenience in an apartment building can face.
Let's start in order, the main request is to make a warm floor in the bathroom, namely in the toilet and bath. This is done so that "wet" and "dark" places are dry and warm. There were requests to install TP in the kitchen, when the entire floor was made with tiles, and where the tiles are, the floor is always "cold" and unpleasant to the touch.
Look at the picture:
You see the schematic movement of hot water in pipes, from the fact that there is a circulation, we always have hot water and a heated heated towel rail performs its function. But what happens when Avito plumbers make your neighbors' dream of warm water floors come true, consider the scheme:
Usually, three shut-off taps are cut into the hot water riser. One for the central riser, two for the underfloor heating outlet tees. The TP pipes have a smaller cross-section than the diameter of the DHW circulation riser pipes. In addition, the length of the transformer substation can be up to 80 meters long. Now imagine what kind of hydraulic resistance this entire system has. And in order to push this mass, a shut-off valve is installed on the riser, which forces the flow to go along a long path with great resistance. What we come to:
Due to the wishes of one of the tenant, we get an imbalance in the DHW in the calculated system. The circulation of water in the riser becomes slower, which makes heated towel rails work poorly or do not work at all. The neighbors on the riser receive hot water that does not meet the standards or a little warm, but you still have to pay according to the meter as if it was very hot.
In addition, some craftsmen manage to connect the warm floor to the central heating system. Forcing, for the above reasons, to freeze the rest of the neighbors in the riser. So, if you just itch to have a warm floor in an apartment building, then do it with the help of special mats or wires, using a heat source from electricity coming through your meter.
