solar evacuated tube

Thermosyphon solar water heater relies on the natural circulation of water between the collector and the tank or heat exchanger. As water in the vacuum tubes is heated it rises naturally into the tank, while cooler water in the tank flows down to the bottom of the vacuum tubes, causing circulation throughout the system to heat the water

Working principle:

BAOGUANG solar evacuated tube assimilate the multiple coatings with spattering deposition technilogy,made from borosilicate 3.3 glass,The CU/SS-AL-ALN gradual change selective complex coating makes evacuated tubes have excellent performance of absorptance and law reflection rate.
