In addition, the floor space in the room is from to tens of square meters, while the heat-transfer surface area of other heating appliances (radiators, convectors, etc.) at best is a value close to a square meter. Thanks This “warm floor” work with a very small temperature drop Dt, ranging from a few degrees in the room with the steady thermal conditions up to ten to fifteen degrees in the regime of forced heating. The Spurs can provide more clarity in the matter. In as a structural element heating device called a “warm floor” is used of the floor construction, which is very effective in terms of material savings, and most importantly – places in the interior. “Warm floor “in this sense resemble the famous Cheshire Cat – himself not only his smile.
The following physical principle of the “warm floor” is that the warmest air is at the bottom, and the most cold – at the top. The distribution of air temperatures at altitude, typical of systems “warm floor” is shown in Fig. right. Here comes into physiology. The fact that only part of the body constantly gives off heat by heat – is the surface feet, so your feet touch heated to a physiologically comfortable temperature 25-28 C (higher temperatures are undesirable for several reasons) immediately causes physiological comfort, and relatively cool air at head level – a feeling of freshness. Virtually none of the thermal devices common today does not create a comfort level that is comparable with the systems of “warm floor”.
