The preheating circulation system consists of circulating water pump, intelligent control system, water pipe fittings, power supply, shell and other components. Before using hot water, the backwater preheater automatically starts to work, the cold water in the hot water pipeline circulates to the water heater for heating, and the hot water flows into the pipeline to ensure the comfort of users in using hot water (hot water standard for five-star hotels).
