The wide distribution systems radiant panel heating in floor heating in wet areas, allows to increase comfort. Part of the thermal energy will increase the rate of evaporation from wetted surfaces. The article describes mathematical model and algorithm of calculation of the temperature field of the surface subject to evaporation. In the paper numerical experiment to analyze the efficiency of the distribution system temperature floor heating in wet areas.
