In Japan, a large quantity of energy is consumed in taking a bath. In this paper, compound system for hot water supplying system of residential use, which consists of heat exchangers, solar panel and a heat storage tank, are proposed to reduce thermal energy supplied by auxiliary heat source. Concerning the proposed hot water supplying system, solar heat collected, recovering heat from the exhaust heat from bath use and thermal energy supplied by auxiliary heat source were calculated by using standard climate data in Tokyo. From the calculated results, it was shown that the proposed system of 3m^2 of solar panel, 200 l of heat storage tank and the system of supplying the hot water in the heat storage tank directly for bath use reduces about 80% of the thermal energy supplied by auxiliary heat source compared with a conventional system.
