The invention discloses A
water circulation system for a
water heater, wherein a circulating water inlet is provided at the lower end of the
water heater, and a circulating
water pipe is provided between the water outlet of the
water heater and the circulating water inlet, and the circulating
water pipe is divided into successively connected outlet
pipe sections, circulation
pipe sections, pressure The
pipe section and the water inlet pipe section, in which the
insulation layer is set on the outer circumference of the water outlet pipe section, the circulation pipe section and the water inlet pipe section, and there is a
height difference between the two ends of the
pressure pipe section. When hot water is not used, the water outlet pipe section Under the action of gravity, the water flows back to the water tank of the water heater along the circulation pipe section, the
pressure pipe section and the water inlet pipe section, so that it can be heated together with the water in the water heater tank and then output, so as to ensure that the water in the
water circulation pipe will not be wasted. , save
water resources, and can ensure that the output is always hot water. In the process of
water circulation, the heat loss of water is small, which saves a lot of energy. The water circulation
system of the water heater has a simple structure and is convenient to use.
