Pressurized Solar Water Heating System
Evacuated tube technology delivers significantly better performance than traditional absorbers in the market today. Their advanced design incorporates tubes that consist of 2 layers of borosilicate glass with a vacuum layer between them. This vacuum acts like a thermos flask, retaining up to 97% of the thermal energy, resulting in increased efficiency. The sun’s thermal energy is then transferred to the manifold via the heat pipe located inside each tube.

The small amount of evaporative liquid in each tube is super heated by the sun’s energy and forms a vapour. The vapor rises to the top of each pipe; this heat is then transferred to the water flowing through the manifold. The heated water is then returned to the tank. The cylindrical design of the tubes ensures effective collection of the sun’s thermal energy throughout the day.
