節する。The operation of the other embodiment shown in FIGS. 4 and 5 will be described. When there is an instruction to fill the bathtub 5, the control device 13 drives the opening / closing valve 10 to open and the hot water heated by the hot water supply side heat exchanger 2 is supplied from the two filling tubes 4 a and 4 b of the filling tube 4. The water is supplied to the bathtub 5 via the going pipe 5a and the return pipe 5b. The combustion control unit 17 adjusts the opening of the proportional valve 9 so that the difference between the hot water supply temperature Th and the set temperature Ts becomes zero during filling.
