Working principle

1. The non-pressurized solar water heater is a open loop system, water is circulating in the system, the storage tank doesn’t bear high pressure, the hot water flows out by gravity.

2.There are CU-AL-SS coating layer on the solar vacuum tubes, it absorb the solar energy and transfer into heat energy to heat the water.

3.As the specific gravities of hot water and cold water are different, 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.

5.If choose optional assistant tank, it will make up water automatically when water in storage tank is being used up. When water is full, it will stop making up water itself, no any manual operating.
