We start our calculations from probable heat loss in a particular building or room. In the modern well-insulated building heat losses do not exceed 6 watts per sq.ft of space. In the buildings with mediocre insulation it comes to 8 watts. In the poorly insulated buildings and premises the volume of heat losses comes to 10 watts. Thus, in order to compensate for heat loss in buildings with mediocre insulation the coating with the capacity of 8000 watts is needed for the area of 1000 sq.ft. When using Carbontec® heating material with the capacity of 251 W, the consumption rate will constitute 340 sq.ft of the material.
