Thermosyphon system(ALT)

 

Thermosyphon 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.

NOTE:Absorber area is the part of the collector that actively absorbs the light rays. For solar tubes this is defined as the cross-sectional area of the inner tube (selective coated) measured using the outside diameter. (Eg. 0.047 x 1.72m = 0.08m2)
