If a hot water supply operation is performed during the daytime by taking a lifestyle pattern of using a large amount of hot water during 0:00, the control for storing hot water during the morning time period is performed. It is possible to make it difficult for the hot water operation to occur. Also, if you take a life pattern in which no hot water operation is performed during the daytime,
Since the second predetermined amount β2 converges to a small value, the stored hot water is not wasted, and the electricity cost can be reduced. Since the second predetermined amount β2 is updated every day, it is possible to make the hot water supply operation follow the usage pattern of the user.
