<P>PROBLEM TO BE SOLVED: To provide a water heater which can prevent supply of hot water set high exceeding a general hot water supply set temperature during general hot water supply when the set temperature of bath hot water is higher than the set temperature of the general hot water supply. <P>SOLUTION: In the water heater 1 serving as a heat exchanger where heat exchanger 50 for hot water supply is used for both general hot water supply and bath hot water supply, a controller 100 controls a hot water supply circulation pump 44 so that a hot water temperature after heat exchange at the hot water supplying heat exchanger 50 becomes a temperature corresponding to a general hot water supply set temperature, when it detects general hot water supply during bath hot water supply, in a case when the bath hot water set temperature is higher than the general hot water supplying set temperature, and controls the opening degree of a flow regulating valve 32 in a close direction when both of the bath hot water supply and the general hot water supply are simultaneously carried out. <P>COPYRIGHT: (C)2012,JPO&INPIT |
