The function of integrated water heater recovery tray is a water inlet structure of electric water heater with heat energy recovery function.

since both the water storage type and the quick-heating type electric water heaters are used with hot water and cold water at the same time, the cold water entering the hot water tank often takes a long heating time and consumes a large amount of electricity, which is inconvenient to use. However, after the warm water is showered on the ground after bathing, the heat is wasted, which is not energy-saving and environment-friendly. Therefore, the recovery tray is a combination of the two, and a structure that can preheat the cold water in the tap water pipe by using the waste heat of warm water is designed. Therefore, an integrated heat energy is provided.
