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 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 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
