Because the first living water branch section 101 is communicated with the first heat exchange water branch section 201, the loss in the heat exchange water pipeline can be supplemented at any time, and the first living water branch section is not connected with the living water inlet 6 through the pipeline any more, so that the structure is simple. When the temperature of the domestic hot water required in winter is high, the hot water in the heat exchange water pipeline directly flows to the domestic water outlet 20 through the first valve 221, so that the domestic hot water with high temperature can be provided for use. When the temperature of the domestic hot water required in summer is lower, the first valve 221 is switched to the fifth position where the heat exchange water supply section 202 is communicated with the second heat exchange water branch section 203, the domestic water flows out after exchanging heat with the heat exchange water pipeline in the plate type heat exchanger, and the temperature of the hot water flowing out from the domestic water outlet 20 is lower.
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While still being apparent from variations or modifications that may be made by those skilled in the art are within the scope of the invention.
