Claims

[Scope of utility model registration request]

Depending on the temperature difference before and after heating by the bath burner 2 heating the remaining hot water, the heating time, and the thermal efficiency, the temperature of the bathtub 1
When calculating the amount of hot water remaining within 0 and dropping hot water into the bathtub 10 in an amount obtained by subtracting the amount of hot water from a predetermined amount set in advance, prior to calculating the amount of remaining hot water, the power switch 31 is turned on multiple times. Only once in
A certain amount of water counted by the water supply flow rate sensor 14 is passed from the hot water supply circuit 22 to the bath heat exchanger 1, heated by the bath burner 2, and the temperature difference between before and after the bath heat exchanger 1 is detected. A fully automatic water heater with additional heating, characterized by calculating thermal efficiency and correcting the thermal efficiency at the time of calculating the amount of remaining hot water.
