Solar water heating system details
Model: QAL-CG-25

How solar water heating systemworks,

1. Solar water heating system 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 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 becaomes 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 solar water heating system tank will be gradually heated.
Solar water heating system features

1. Cheap and reliable solution, Simple structure, Easy installation
2. High efficiency
3. Withstands water pressure no more than 0.1MPa
4. Operated without any power supplying
5. Electric heater can be used as back up in rainy days
6. Hot water can be used directly, or can be used as a pre-heated
