Claims

[Scope of utility model registration request]

Compressor 1, air heat exchanger 2, pressure reducing device 3. 2-way switching valve 4
, a water-refrigerant heat exchanger 5, a heat storage tank 6 for storing hot water obtained by the system, a circulation pump 7, water piping 8, and a water temperature detection thermometer 9. Operation control of a heat pump heat storage water heater characterized by forcibly operating a circulation pump for several minutes when the power is turned on and at regular intervals thereafter to ensure correct detection.
