What’s…Vacuum Tube Collectortype Solar Water Heaters works efficiently in cold climates or in 70 Deg. Hot water outlet applications? The construction of the collector tube is similar to a thermos flask, piece in that it comprises of two borosilicate glass tubes, one sealed inside the other. The outside of the inner glass tube is coated with a solar selector surface (Al-N/Al) & the space between the two tubes is evacuated & maintained at a high vacuum. This Vacuum created inside the high strength borosilicate glass tube act as an insulator supporting heat loss & enhanced performance.
The use of 3.3 borosilicate glass makes this vacuum tube highly resistant to chemical & thermal shock.
They are designed to suit hard water heating. There is no bonding of scales on smooth surface of glass tube. Cleaning of collector is very easy.
