Abstract (en)

[origin: EP2921789A1] Information that is obtained from the side of a hot-water storage tank is correctly conveyed to the side of a heat source device. A hot-water supply system 1 includes a heat source device 3; a hot-water-stored-amount detecting unit 21 that detects the amount of hot water stored in a hot-water storage tank 20; an electrical valve 9 that adjusts the flow level of heated hot water supplied from the heat source device 3 to the hot-water storage tank 20; a control unit 30 that is provided in the heat source device 3 and that controls the heat source device 3 based on information about the amount of stored hot water detected by the hot-water-stored-amount detecting unit 21 and a degree-of-opening signal of the electrical valve 9.
