PROBLEM TO BE SOLVED: To connect a hot-water supply control device 4 with a communication line 16 to a system control unit 15 which manages a battery device 6 and a photovoltaic unit 8 to improve total energy efficiency, and to prevent the hot-water shortage of a hot-water supply device 5.SOLUTION: A hot-water supply control system includes a hot-water storing tank 2 which stores hot-water boiled by a heat source machine 1 and a hot-water supply control device 4 which controls the heat source machine 1, and for example, a system control unit 15 serving as a center of an energy management system which controls a battery device 6 to be charged by a commercial power supply. The hot-water supply control device 4 is controlled by the system control unit 15, and the boiling of the hot-water in the hot-water storing tank 2 using the heat source machine 1 by means of the hot-water control device 4 is made to coexist while distinguishing a boiling operation by the instruction of the system control unit 15 from the boiling operation by the autonomous instruction of the hot-water control device 4 itself. Thereby, total energy efficiency can be improved and the hot-water shortage or the like of a hot-water supply device 5 can be prevented. |
