ある。 Next, when hot water is used at the hot water tap 25 during automatic bath operation, when water flow is detected by the water flow switch 27, the three-way valve 17 is switched to open to the bypass pipe 16 side. At the same time, the hot water supply side is controlled to reach the set temperature used by the hot water tap 25. On the other hand, since water is supplied to the hopper 15, the temperature of the water drops. This is detected by the temperature sensor 18, and the gas solenoid valve 24 is opened to heat the bathtub heat exchanger 3. When the hot water supply is finished, the water flow switch 27 detects it.
Three-way valve 1 so that hot water can be dropped from heat exchanger 2 again.
Switch 7. When the temperature sensor 18 detects that hot water is supplied from the hopper 15, it closes the gas solenoid valve 24 and continues automatic bath operation. The water flow switch 13 is used to detect water flow after the circulation pump 12 is driven when reheating the bath, and is used to prevent dry heating.
