[0074] The water heated by the instant heating subunit enters the heat storage subunit or the water outlet subunit 200. The hot water in the heat storage subunit is used to exchange heat with the normal temperature water input into the heat exchange subunit. The water that has been heated through heat exchange in the heat exchange subunit enters the water outlet subunit 200 or enters the instant heating subunit. The water inlet subunit 800 is connected to the heat exchange subunit, the heat storage subunit, the instant heating subunit, and the water outlet subunit 200 through pipelines.

When the circulating hot water exchange path is working, the third control valve 13 is in the closed state, so that the first pumping component 43 pumps the water (hot water) in the heat storage tank from the heat storage tank to the first end of the second pipe of the heat exchanger 32. The heat in the hot water is exchanged to the first pipe of the heat exchanger 32 and then cools down, and then flows back to the heat storage tank from the second end of the second pipe of the heat exchanger 32.

[0089] The heat carried by the second pipe of the heat exchanger 32 is exchanged to the first pipe of the heat exchanger 32 to increase the temperature of the water flowing through the first pipe of the heat exchanger 32, thus realizing heat exchange.
