Features:
This type is a compact non-pressurized system. It is the natural circulation system that works on a light absorption principle. The solar collector converts solar energy into thermal energy, then heat the water step by step. The temperature within the cylinder allows the natural water circulation to operate, transferring the heat water to the top of cylinder and heating the cold water at the bottom at the same time.
How non-pressure solar water heater works1. 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. 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 water tank will be gradually heated
