Referring to fig. 3, in an embodiment, in order to improve the heating efficiency of the domestic water, a stop valve 150 may be disposed between the outlet of the first water pump 130 and the inlet of the second flow passage 112. When the heating and water heating apparatus 100 is turned on, the first water pump 130 and the stop valve 150 may be turned on first, and cold water originally remaining in the domestic water pipeline 200 may be pumped into the first flow passage 111 by the first water pump 130 to be heated, and then may flow into the domestic water pipeline 200 from the domestic water outlet 104 after being heated. When the heating and water heating apparatus 100 heats the domestic water, the first water pump 130 and the stop valve 150 may be closed, and at this time, the water flowing in from the domestic water inlet 103 may flow only into the fourth flow passage 122 of the sub heat exchanger 120 to be heated, and then may flow into the domestic water line 200 from the domestic water outlet 104 after being heated.
Further, referring to fig. 3, in order to prevent the water flowing out of the second flow passage 112 from flowing back into the fourth flow passage 122, the heating and water heating apparatus 100 includes a first valve 160, and the first valve 160 is disposed between the domestic water inlet 103 and the inlet of the fourth flow passage 122; alternatively, the first valve 160 is disposed between the domestic water outlet 104 and the outlet of the fourth flow passage 122.

When a user needs a large amount of domestic hot water provided by the heating and hot water apparatus 100 or is in a bathroom mode, the diversion control device 170 closes the first outlet end, opens the second outlet end, and prevents water flowing out of the first flow channel 111 from flowing to the heating water outlet 102, so that water in the first flow channel 111 flows into the third flow channel 121 to heat the domestic water in the fourth flow channel 122, so as to provide more domestic hot water for the user.
