When the ON signal is output, it is possible to monitor the water level in the bathtub with the water level sensor (21), so the hot water supply operation is performed immediately until the set water level is reached while determining the water level detected by the water level sensor (21). To continue. As a result, in this conventional example, depending on the presence or absence of residual water in the bathtub (1), the air is removed from the reheating circuit (2) connected to the water level sensor (21) or the bathtub (1) is connected to the water level sensor (21). The additional hot water supply can be performed.

When the falling sound disappears, the water level can be monitored. In this way, by determining the presence or absence of submersion of the bathtub side opening by the operation of the vibration noise sensor provided in the water passage (30),
It is possible to detect the presence or absence of water in the bathtub while continuing the hot water supply operation into the bathtub (1).
