PROBLEM TO BE SOLVED: To provide a hybrid hot water supply system capable of performing hot water supply in the daytime by a hot water storage device using electric power such as a heat pump as a driving source while avoiding a peak power time zone.SOLUTION: A hot water supply device is configured in such a manner that: estimated hot water usage amount by the time zone is predicted based on the past hot water supply amount actual record information; information regarding a peak power time zone supplied by an electric power supplier is acquired; and an operation time zone of the a hot water storage device is set based on hot water storage capacity information of the hot water storage device and the estimated hot water usage amount by the time zone in such a manner that it does not overlap with the peak power time zone and hot water of the estimated hot water usage amount in the time zone is stored at the start time of each time zone; and the hot water storage device is actuated at the set operation time zone. |
