All Glass Three Target Vacuum Tube Solar
Vacuum tube solar specification
Vacuum tube solar working principle
After installation and check the heating collector system correctly, cold water is filled in the water tank. Due to gravity, cold water flowed into the vacuum tubes, absorbing the heat (which the temp. might reach 250 degree centigrade). Cold water changes into hot water and goes back to the water tank.
