Background

The solar water heater mainly comprises a water tank and a row of evacuated solar collector tubes arranged at the bottom of the water tank, under the irradiation of sunlight, water in the evacuated solar collector tubes is heated and then flows back into the water tank, and cold water in the water tank sinks into the evacuated solar collector tubes, so that microcirculation is generated between the evacuated solar collector tubes and the water tank, and hot water is finally formed in the water tank. However, in cold places and in winter, because the pipe diameter of the heat collecting vacuum pipe is thin, water inside the heat collecting vacuum pipe is often frozen, and therefore the cyclic heating of the solar water heater is affected. However, the electric heating tube needs to heat the whole water tank, and it takes a long time to heat the whole water tank to the required temperature, which consumes a large amount of electric energy, and if the amount of hot water used each time is not large, for example, washing dishes, faces, hands, etc., it takes a long time to heat the whole water tank.
