The hot water circulation system can achieve instant heating at the end water point, and hot water can be used in about a few seconds. In order to ensure that the water point is instantly heated, it is undoubtedly necessary to keep the water temperature of the hot water supply pipe at the required temperature at all times. It mainly relies on the continuous operation of the hot water circulation pump to continuously send hot water into the water supply pipe and return the cold water to the hot water storage tank. Generally, the hot water circulation control can maintain hot water for 24 hours, but when the hot water is not needed at the water point, it is still circulated, which will cause energy waste.
