PRODUCT STRUCTURE

WORKING PRINCIPLE

Solar Vacuum Tubes are the absorber of the solar water heater. They absorb solar energy converting it into heat energy for use in water heating. The hot water rise to water tank and the cool water fall to the bottom of the vacuum tube.

As the gravity theory, the hot water and cool water are continuously circulation in the vacuum tube and water tank.
