<P>PROBLEM TO BE SOLVED: To provide a heat pump hot water supply device capable of improving heating efficiency in a heat pump and hot water storage efficiency in a hot water storage tank by discharging intermediate temperature water in the hot-water-storage tank as much as possible. <P>SOLUTION: In the heat pump hot water supply equipment including a heat pump heating means 21 to heat hot water in the hot water storage tank 1 and a boiling-up control means 32 which initiates boiling up of the hot water in the hot water storage tank 1 by the heat pump heating means 21 in a predetermined time zone and stops boiling-up when hot water flowing into the heat pump heating means 21 exceeds a predetermined boiling-up termination decision temperature, a decision means 33 is prepared to decide whether the intermediate temperature water is fully discharged from the hot water storage tank 1, and when it is decided that the decision means 33 can not decide a fully discharge of the intermediate temperature water, the boiling-up control means 32 is forced to lower a termination decision temperature for bubbling. <P>COPYRIGHT: (C)2012,JPO&INPIT |
