Claims

[Scope of utility model registration request]

a bath circulation circuit 9 connecting a bath heat exchanger 1 heated by a bath burner 2 and a bathtub 8;
The bath circulation circuit 9 and the hot water supply circuit 20 are equipped with a hot water supply circuit 20 that supplies hot water from a hot water tap 18 provided at an appropriate location via a hot water heat exchanger 10 heated by a hot water supply burner 11. It communicates with the hot water supply circuit 2 through a hot water filling circuit 21 equipped with a solenoid valve 23, a vacuum breaker 24, and check valves 22, 25.
0 directly to set amount of hot water at set temperature to bathtub 8
In a device that performs automatic hot water filling by pouring hot water into the water, the hot water supply circuit 20 or the hot water filling circuit 21 is provided with a flow rate sensor 12 that detects the amount of hot water poured, and the actual measured flow rate detected by this flow rate sensor 12 is provided. This fully automatic water heater with reheating is equipped with a display means 31 that calculates the set amount of hot water and the set amount of hot water and displays the remaining time until the completion of hot water filling.
