PROBLEM TO BE SOLVED: To provide a hot water supply system capable of leveling a power load by suppressing power consumption in a time zone early in the morning.SOLUTION: A hot water supply system 100 includes: a hot water supply device 110 performing boiling operation by using at least system power 130; and a hot water supply ECU 113 performing the boiling operation using the system power 130 by controlling the hot water supply device 110 during a predetermined time zone during which an electricity rate of the system power 130 is not expensive than that of the other time zone. As a result of determination using a predetermined command signal, various information related to sun light obtained from the outside, or various past result information stored therein, the hot water supply ECU 113 hastens the end time of the boiling operation performed in the predetermined time zone by a predetermined time when an early ending condition is met. |
