Features:
1. It is non-pressurized thermosiphon solar water heater with water tank, and is economical as a natural circulation system.
2. It uses vacuum tubes, the water could be heated in tubes directly.
3. Very popular in torrid zone and warm areas.
4. The installation and maintain is very easy.
How compact non-pressurized solar water heater works?
1. All glass evacuated tubes are integrated with storage tank, it is ideal for use in houses and other applications where requires cheap, reliable hot water supply.
2. As the specific gravities 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
