Zusammenfassung:	PROBLEM TO BE SOLVED: To easily and securely remove a scale adhered to the inside of a water heat exchanger of a refrigerant-water heat exchanger. SOLUTION: In this cleaning method, to remove the scale on the water heat exchanger 14B of the refrigerant-water heat exchanger 14 of a heat pump water heater for performing heat exchange between a refrigerant heated by a heat pump cycle X and water in a hot water storage tank 22 by the refrigerant-water heat exchanger 14, a washing machine 45 is connected to a heat pump unit 11 and slightly acidic washing water is circulated and supplied to the water heat exchanger 14B.
