2.Features of non pressure system

-With triple selective coating, it has a higher heat efficiency than common vacuum tubes

-Water flows by the principle of siphon

-Cheap price but good quality

-Simple structure and easy installation                                                 

-Withstands water pressure no more than 0.1MPa  

-It is suitable for the area with enough insolation          

-Electric heater can be used as back up in rainy days


3. Non pressure solar water heater working principle

-Solar riadiation is absorbed by the selective coating of solar vacuum tube, it changes solar energy into heat energy.

-Water in vacuum tube absorbs the heat energy and becomes hot.

-As water's temperature rises up, its density decreases, so hot water floats up and cold water floats in to replace void.

-Through this circulation, the cold water in the water tank will be gradually heated.
