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.
