Abstract (en)
[origin: EP2685177A1] Energy efficiency is improved. A heat pump water heater 1 includes: a heat pump unit 2 including a refrigerant circuit 3 in which a refrigerant condensing in a condenser 22 circulates; and a hot water storage tank 5 which stores hot water heated in the condenser 22. An operation mode is selectable from a circulation heating mode in which heated hot water is supplied to the hot water storage tank at a first flow rate, and a non-circulation heating mode in which heated hot water is supplied to a top portion of the hot water storage tank 5 at a second flow rate lower than the first flow rate. The operation mode is switched between the circulation heating mode and the non-circulation heating mode based on the temperature of the refrigerant supplied to the condenser 22.
