In a control unit of a hot-water supply system, a boiling time period is estimated based on a hot-water amount stored in a tank at a time of 23:00, a boiling start time is adjusted so that boiling operation is finished at a time immediately before 7:00. For example, when the hot water amount stored
In a control unit of a hot-water supply system, a boiling time period is estimated based on a hot-water amount stored in a tank at a time of 23:00, a boiling start time is adjusted so that boiling operation is finished at a time immediately before 7:00. For example, when the hot water amount stored in the tank is smaller at the time of 23:00, the boiling time period is made longer and the boiling start time is made earlier. On the other hand, when the hot water amount stored in the tank is larger at the time of 23:00, the boiling time period is made shorter and the boiling start time is made later.
