Evacuated tubes are the absorber of the solar water heater. They absorb solar energy converting It into heat for use in water heating. Evacuated tubes have already been used for years in Germany, Canada, Chin and UK. There are several types of evacuated tubes in use in the solar industry. At Sunlit, we use the "Twin-Glass Tube" technology. This type of tube is chosen for its reliability and better performance.
