PROBLEM TO BE SOLVED: To provide a hybrid hot water supply system capable of performing appropriate hot water supply even in a prescribed situation in which hysteresis control becomes unstable.SOLUTION: A hybrid hot water supply system of this invention includes priority operation selection means which has a first mode in which hot water is supplied from a first water heater and a second mode in which hot water is supplied from a second water heater and which selects one of these. The hybrid hot water supply system is configured in such a manner that, every time power is supplied to a controller according to a re-operation of the system, it becomes possible to perform hysteresis control with the first mode being a start point by preferentially operating the first mode temporarily, so that stable hot water supply control can be performed based on the hot water temperature in a hot water storage tank. |
