As a result, on one hand, the discharged cold water is directly discharged to cause waste of water resources; on the other hand, after each hot water use is finished, the hot water remained in the conveying pipeline gradually dissipates heat and cools, so that unnecessary energy loss is caused.
In order to solve the problems, the Chinese patent represented by the application number 201711260282.9 provides a technical scheme of adding a circulating water return pipe in a water supply system, and the circulating water pump is used for keeping hot water circulation in a connecting pipeline, so that instant heating is realized, and water resource waste caused by cold water discharge is avoided. However, such a solution brings problems in that: 1) The additional configuration of the return water pipe is needed, so that the cost and the pipeline installation difficulty are increased; 2) The problem of energy loss of the retained hot water in the connecting pipeline after the hot water is used cannot be solved; 3) The water heater is only suitable for supplying hot water with one water heater connected with one faucet, and is not suitable for a hot water supply system with one water heater connected with a plurality of faucets.
