Abstract (en)

In a case where a stored hot water temperature target value and a stored hot water amount target value for a next day and afterwards are changed depending on use result data, if it is determined that a minimum heat storage amount is excessive from the use result data, the stored hot water temperature target value is decreased with priority, and if the stored hot water temperature target value reaches a lower limit value, the stored hot water amount target value is decreased. If it is determined that the minimum heat storage amount is insufficient from the use result data, the stored hot water amount target value is increased with priority, and if the stored hot water amount target value reaches an upper limit value, the stored hot water temperature target value is increased. Thus, energy saving can be achieved.
