PROBLEM TO BE SOLVED: To provide a hot water supply system capable of keeping the temperature of a storage battery within an appropriate temperature range at any time of the year by efficiently using cold generated by the hot water supply system.SOLUTION: A hot water supply system 100 includes: a refrigerant circuit 20; a hot water storage tank 35; a storage battery 71; a temperature adjustment circuit 40; and a temperature adjustment jacket 48. The refrigerant circuit 20 includes: a water heat exchanger 22 radiating heat from refrigerant; and an air heat exchanger 24 heating the refrigerant. Unheated water is supplied to the hot water storage tank 35 from below, and the hot water storage tank 35 stores hot water heated by the refrigerant circuit 20 above. The storage battery 71 stores electricity used by at least the refrigerant circuit 20. The temperature adjustment circuit 40 circulates water that exchanges heat with the refrigerant of the refrigerant circuit 20 circulating halfway from the water heat exchanger 22 toward an outlet of the air heat exchanger 24. The temperature adjustment jacket 48 adjusts a temperature of the storage battery 71 in the temperature adjustment circuit 40. |
