温水からの温水タンク４への加温は停止される。The hot water in the hot water tank 4 with a heat-retaining structure is kept at a predetermined temperature (for example, 3
8°C) or lower and the heating sensor 4 detects 40°C or higher, the heating pumps 12 to 12 are activated to supply surplus hot water to the heat exchanger 13 in the hot water tank 4. The hot water in the hot water tank 4 is heated to 38°C. When the hot water sensor 6 detects that the hot water in the hot water tank 4 has reached 38°C, the heating pump 12 is stopped, and heating of the hot water tank 4 from the surplus hot water is stopped.
