Regular water heater:

water heater relies on the natural circulation of water between the collector and the tank. As water in the vacuum tubes is heated, it rises naturally into the tank, while cooler water in the tank flows down to the bottom of the vacuum tubes, .As this circulation works throughout the whole system constantly, so we get the hot water.

I.The Necessary part of the water tank:

It works as the heat reserve tank, which require high quality of inner tank and preservation material;

II. The Necessary part of solar vacuumTube:

Evacuated tubes are the absorber of the solar water heater. which absorbs

solar energy and convert it into heat then transfor the heat into water for use in water heating.It is the most improtant part of the solar water heater.

It consists of two borosilicate glass. the inner tube is coated with a sputtered solar selective coating (Al-N/Al) or (Al-N/AL/SS/CU), this coated inner tube is closed at one end and sealed at the other end to the outer tube.

the annular space between the outer tube and inner tube is evacuated to virtualy eliminate heat loss by conduction and convection. And the outer tube is transparent allowing light rays to pass through with minimal reflection.This "evacuation" of the gasses forms a vacuum, which is an important factor in the performance of the evacuated tubes.

III.The parameter of whole system:

VI. Optional parts:

A controller----show water level, temparature for the conveince of cold water supply

Water auot filling tank(assistant tank): it used to supply the cold water automatically. When the water tank reduces to a certain level, the assitant tank will supply the cold water automatically untill the water tank is full. The angel of bracket is decided according to your latitude.Its performance is stable ,reliable and easy installation.It adopts scientific structure to reach the best performance.The system can be perfectly integrated with architecture.The system can endure the maximum pressure up to 0.2 Mpa.

An electric heater: when without sunshine ,etc: in rain days and winter days,use for heating water.
