Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a hot water supply system that does not lower a coefficient of performance of a heat pump unit.SOLUTION: A heat pump water heater system includes: a hot water tank 1 to the upper part and the lower part of which a circulation flow channel 11 is connected; a heat pump unit 2 for heating hot water flowing in the circulation flow channel 11 by a condenser 22; a solar heat collecting unit 3 having a heat collector 31 for collecting solar heat, and a plurality of radiators 32a to 32c disposed in the hot water tank; and a control means for deciding a destination of a heat medium out of the radiators 32a to 32c based in a relative relation of a temperature of the hot water in the hot water tank 1 and a temperature of the heat medium sent to the radiators.
