Compact Non-pressure Solar Water Heater
Working principle:
The non-pressure thermosiphon systems rely on the nature circulation of the water between solar tubes and the water tank. Thermosiphon systems work on principal of difference between hot water and cold water. When water in vacuum tubes is heating, it become lighter and rise, cold water coming down at the same time to make the circulation between tubes and tank.
