High Efficiency Vacuum Tube Solar Water Heater Evacuated Tube Collector 

200L 316 Stainless Steel Thermosyphon Non Pressurized Vacuum Tube Solar Water Boiler High Efficiency

Working principle:

Non-pressure solar water heater of all glass evacuated tube collector integrated with storage tank, are ideal for use in houses and other applications where cheap, reliable hot water supply is required.
They are simple, economic and practical.
As the specific gravity of hot water and cold water are different, cold water goes downward and hot water goes upward.
When cold water in evacuated tubes is heated, it becomes lighter and goes to the water tank.

While cold water in the tank goes down to the evacuated tubes
Through this circulation, the cold water in the water tank will be gradually heated.
