Blueclean flat plate non pressurized solar water heater is a kind of thermosyphon solar water heating system to transfer heat from collector to water inside tank. The collectors are coated with a heat-absorbent surface which absorbs the sun rays and heats the fluid in the collector. As the fluid heated, it?rises to top of the collector panel?and flows into the tank, while the cooler fluid in the tank flows to the bottom of the collector panel, then the process repeats and causes the circulation in the system.
