<P>PROBLEM TO BE SOLVED: To provide a method of determining an optimum boiling-up set temperature in a heat pump storage type hot water supplying/heating device executing 24-hour heating. <P>SOLUTION: In this heat pump storage type hot water supplying/heating device which includes a hot water storage tank 1 for storing hot water/water, a heat pump type heating means 4 for heating hot water/water in the hot water storage tank 1, and a heating circuit 15 performing a heating operation by applying the hot water/water in the hot water storage tank 1 as a heat source, and in which the hot water/water in the hot water storage tank 1 is boiled up by operating the heat pump type heating means 4 in a late-night time zone, and the hot water/water in the hot water storage tank 1 is reheated by operating the heat pump type heating means 4 when a heat accumulation amount in the hot water storage tank 1 becomes insufficient in a daytime zone, in a case when the hot water storage tank 1 is not kept in an approximately full state at the termination of the late-night time zone, the next boiling-up set temperature is lowered, and in a case when a time of the reheating operation in the daytime zone is more than a prescribed time, the next boiling-up set temperature is raised. <P>COPYRIGHT: (C)2011,JPO&INPIT |
