Since the water does not circulate in the circulation line 60, it can be determined from the water flow detection signal Dw2 of the water flow sensor 62. In this case, the mode does not shift to the reheating mode.

After raising the water level above the circulation port 54 by supplying the water amount, the operations of the steps (a) to (h) are performed, but the water amount corresponding to 1/2 of the set appropriate water level hwo of the bathtub 20 is reduced.
