With the continuous improvement of living standard and energy-saving and environment-friendly requirements, the application of a centralized (semi-centralized) hot water supply system is more and more common. By replacing the distributed hot water supply mode of an electric water heater using pure electric energy as a heat source, the application places of the concentrated semi-concentrated hot water supply system are gradually popularized to apartments and residences from traditional important public buildings, hotels, high-grade office buildings and the like. Therefore, the improvement of the energy-saving and water-saving efficiency of the centralized (semi-centralized) hot water supply system has extremely important significance for energy conservation and emission reduction of the country.

The operation principle is that the hot water in the main water tank 200 is delivered to each user side water using equipment 500 through a hot water delivery pipe 400 by a hot water pump 300; in order to ensure that the water temperature of the user side water using equipment 500 meets the design requirement of the specification at any time, the circulating pipe 600 is arranged to form a circulating pipe network, so that hot water can continuously circulate through the main water tank 200 to supplement the lost heat. However, in order to ensure that the temperature of the supplied hot water meets the design requirements of the specification at any time, the hot water needs to be circulated in the circulation pipe network for a long time without interruption, so that the operation energy consumption of the hot water pump 300 is increased; in addition, the external surface area of the circulating pipe network is large, so that the circulating pipe network generates a large amount of heat loss. In order to reduce the loss of thermal energy and electric energy generated by hot water circulation, some users adopt management measures for limiting the use in peak time, but the management measures can cause serious inconvenience of water use.
As shown in fig. 2, in part of small and medium-sized hot water supply projects, particularly reconstruction projects, the construction cost is reduced, the engineering construction is convenient, the circulating pipe 600 is eliminated, and the circulating pipe network is simplified. The operation principle is as follows: the hot water in the header tank 200 is supplied to each customer-side water using device 500 through a water supply pipe 400 by a hot water pump 300. However, in order to ensure the hot water supply, when the user uses the hot water intermittently, the cold water in the water supply pipe section between the heat source and the hot water equipment is often discharged, which causes waste of water and heat.
In view of the above, the applicant has made an intensive study on the above-mentioned defects in the prior art, and has made this invention.
