PROBLEM TO BE SOLVED: To provide a hot water storage type hot water system capable of performing water quality improving operation while assuring a state of high operation merits.SOLUTION: This invention relates to a hot water storage type hot water system operated in such a way that an operation control device performs an operation plan processing for feeding out a time-series output plan value of both heat and electricity supply device for supplying electrical power to an electrical power demand part and supplying heat to a heat demand part, feeding out a plurality of estimated operation merit values when the output plan value of the heat-electricity supply device fed out by the operation plan processing is changed on the basis of assumption that the heat-electricity supply device and a water temperature adjustment device are operated to perform water quality improving operation under an imaginary operating state in the future imaginary performing time upon satisfying water quality reduction condition while imaginary performing time and imaginary operating state being made different, and then, the imaginary performing time and the imaginary operating state where operation merit values can be assumed high are determined as the planned performing time and the planned operating state in water quality improving operation.SELECTED DRAWING: Figure 2 |
