120L Solar Water Heaters Working Principle:
Thermosyphon solar water heater(compact non-pressure solar water heater) relies on the natural circulation of water between the collector and the tank or heat exchanger. As water in the vacuum tubes is heated it rises naturally into the tank, while cooler water in the tank flows down to the bottom of the vacuum tubes, causing circulation throughout the system.
