Abstract

PURPOSE:To improve follow-up property to the reduction in set temp. by a method wherein when actual hot water temp. is sufficiently higher than the set temp. at the change time of the set temp. for hot water supply, a circulation pump is driven to circulate the hot water and the circulation amount is larger than that at insulating operation with the OFF condition of a heater. CONSTITUTION:When set temp. for hot water supply is sufficiently reduced in an insulation mode and the hot water temp. is higher than a new set temp. by a constant temp. beta, e.g. 5 deg.C, a circulation pump 51 is ON with the OFF condition of an electric heater 53 and a control valve 5 for the water amount is widely opened. Thereby, a large amount of hot water is circulated to reduce the hot water temp. by the use of heat radiation during circulation. This opera tion is continued until the hot water temp. becomes lower than the set temp. + the constant temp. beta. By this constitution the follow-up property of the hot water supply temp. can be improved even though the set temp. is sufficiently reduced.
