On the other hand, the third preset temperature T 3 Less than a first predetermined temperature T 1 So that the water temperature in the heating water outlet pipe 111 is less than the third preset temperature T 3 In this case, the water in the heating water outlet pipe 111 is heated by the constant temperature water in the water tank 140.
Third predetermined temperature T 3 Greater than a second predetermined temperature T 2 And after the heating furnace 10 stops operating in the heating mode, the water temperature of the heating water outlet pipe 111 can be reduced to be lower than the third preset temperature T 3 Second predetermined temperature T 2 And the temperature of the water in the heating water outlet pipe 111 is lowered to be lower than a second preset temperature T 2 In this case, the step of controlling the heating water outlet pipe 111 to be switched from the first state to the second state is performed, and the hot water for heating the user can be heated by using the warm water in the water tank 140.
