Vacuum Tubes Solar Water Heater

Evacuated Tube Collector (ETC) acts as an absorber in the solar water heater. Each evacuated tube consists of two glass tubes having vacuum in between which is an excellent insulator. The incident solar radiation falling on the tube passes through the outer transparent tube and strikes the outer of inner tube. It absorbs heat energy and then passes to the cold water flowing in the tube. An evacuated tube technology based solar water heating system is most energy efficient and cost effective. Suitable for domestic use. Polyurethane insulation water tank for hot water storage up to 72 hours. Stainless Steel inner tank for longer system life. Triple layer coated vacuum tubes for higher efficiency.
