The popularity of these heating systems is constantly growing. For example, in Sweden 90% of newly built houses equipped with a heating system with Radiant Heating, in Finland - 50%.
There are two main types of warm floor: water and electric. Air floors, because of their exotic and expensive, will not be discussed. And water, and a PEX tubing warm floor one thing in common - a low temperature heater (the temperature of the floor surface rarely exceeds 30-32 ° C), very large area. Usually the whole floor area radiates heat.
However, if the room is planned to install furniture or equipment that will not move, then the warm floor beneath them is not done. The design of such floors is as follows. First is dirt or concrete base, then - a layer of warmth and waterproofing. Insulation laid on top of concrete screed with fuel elements: pipes of hot water or electric radiant heating. You may ask: "Why do you complicate things, when you can just hang on the walls of the battery?". Answers - for comfort.
The author has personally experienced something almost heavenly bliss, which provides such a system. Being in the house where the only heating was warm floors, I was surprised that the air temperature in the room did not exceed 18-19 ° C. In the yard - minus 24 ° C, and a general sense - all the comforts. The house shed a soft, pleasant warmth. Arrogant cat was not to banish from the tiled floor, where the animal warmed after a walk down the street.
The explanation can be found on the plot of temperature distribution depending on the height of the room. Everyone knows that under the traditional heating system (radiators and convectors) heated air rises and cools down, fall down. Therefore, the ceiling is hot, at the floor level is cool, but at the height of the head temperature is somewhere around 22-24 ° C.
A different picture emerges in the room if the heat source - the floor. There is also the warm air rises to the top. But there are significant differences: the temperature of batteries or convectors high - +70 ° C, with the temperature gradient is large enough, loud and the air velocity in the resulting convective flow. Inevitably drafts, because the size of radiators or convectors are limited, and the air is heated, rises strongly over the radiator and goes elsewhere. Thus, in the room formed by a constant and steady current of air, which moves together with the dust, pet hair and other household pollution. You have not asked ourselves, where so much dust in the closet?
