The working principle of unpressurized solar water heater:

Non-pressurized solar water heater of all glass evacuated tube collector integrated with storage tank are ideal for use in home and other appliance where cheap. Reliable hot water supply is required.They are simple economical and practical.
As the specific gravities of hot water and cold water are different. Cold water goes downwards and hot water goes upward.
When the cold water in the evacuated tube is heated. it becomes lighter and goes to the water tank .while cold water in the tank goes to the evacuated tubes.
Through this circulation .the cold water in the tank will be gradually heated.
