200L Compact Non Pressurized Vacuum Tube Solar Water Heater Stainless Steel Bracket
How non-pressurized solar water heater works?
1. Non-pressurized 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.
2. As the specific gravity of hot water and cold water are different, cold water goes downward and hot water goes upward.
3. 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.
4. Through this circulation, the cold water in the water tank will be gradually heated.
Working principle:
Larger proportion of hot water than cold water, cold water flows downward and hot water goes upward
Water will be heated continuously between water tank and vacuum tube
Hot water always floats on cold water
Hot water flows to water tank from vacuum tubes
Proportion cold water flows to vacuum tubes from water tank
