Will the water in the vacuum tube of the solar water heater and the water in the tank be recycled? Otherwise, the water in the vacuum tube will not become stagnant water?There is no circulating water in the vacuum tube, it is not easy to scale?
Under the action of gravity, the cold water will flow into the vacuum tube. The water temperature in the tank rises gradually. And that。
As the proportion of hot water is smaller than that of cold water, hot water rises to the tank,
The water is circulating, the vacuum tube absorbs the heat, and the heat is directly transferred to the water supply
