8,we could product for customer'special need

It has 15years long life span ,and the vacuum tubes can work individually,

so if the only one of them can't work,it won't influence on the others.

The spare parts can be changed freely .it is suitable for the many resident

buildings.

Working principle:1,The high quality vacuum tubes ansorb the solar ultraviolet ray;then heat the cold water in the vacuum tube2,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 circulatingcontinuously.3,The electromagnetism or ball valve can perform 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 tank ,if the water is full,it will close the valve automatically
