Working principle

1.The high quallity vacuum tubes absorb the solar ultraviolet ray,then heat the cold water  in the vacuum tube.

2.The hot water rise in the top of the water tank,and the cold water sink to bottom then heat by solar collector .So the whole system is always circulating continuously.

3.The electromagnetism or ball valve can perform if the water supply automatically,the water in the tank  is not sufficient ,the electromagnetism valve will open its valve ,the tap water flow in the water tank,if the water is full,it will close the valve automatically
