Let's consider a fairly simple method of installing heated floors in a bathhouse with heating from a sauna stove, that is, an additional source of thermal energy is not required for this purpose. The stove was also built without great expense, since ordinary inexpensive red bricks were used for this, painted on the outside for beauty with impregnation for bathhouse floors.
Warm floors in the bathhouse are easy
The beginning of the floor heating system in question in the bathhouse is an ordinary electric plastic fan installed in the dressing room, on the side near the wall and at some distance from the front of the stove.
We put a metal corrugation on the outlet pipe of the fan, which we give the necessary bends for connection with a metal pipe with a diameter of 108 mm, located behind the wall of the dressing room.
This pipe is first welded along the stove itself to the middle under the stones, then it runs transversely through the entire stove and then drops below the floor level, ending with a 90-degree bend.When lighting and heating a sauna stove, the air pumped by the fan warms up in the pipe from the heat of the stove and spreads between the soil or concrete screed and the floor boards.
The floors warm up in 30 minutes and standing or walking on them is very pleasant and comfortable. Moreover, even in frosts down to -37 degrees Celsius, the heating time of the floors does not increase. Since the floors in a regular bathhouse are made to flow through, warm air penetrates into the bathhouse from under the floors through all the cracks between the boards.
Among the advantages of this method of heating the floors in the bathhouse, it should be noted, in addition to the warm floor, that they are always dry due to the influence of hot air coming from the pipe after heating in the stove. Therefore, the possibility of mold, fungi, wood rotting, etc. is completely excluded.
It is absolutely important to turn on the fan when starting to light the stove. If this is not done for any reason, then reverse draft begins to form. Cold air from under the floor of the bathhouse is drawn into the pipe and, passing through the stove, heats up and is blown out into the fan. Usually this device is made of plastic and therefore a hot air stream can melt it.
It is advisable to choose a pipe for heating the air flow with thick walls so that it lasts as long as possible. A sign that this pipe has burned out will be the smoke that comes from under the floor after the sauna stove is lit.
