Working Principle
Compact non-pressure solar water heater relies on the natural circulation of the water between solar tubes
and the water tank. Thermosyphon systems work on the principle of heat rising. The water enters the bottom of the collector and rises to the tank as it warms. The advantage of this system is that solar heat is stored in a well-insulated tank, so hot water can be used at any time without the penalty of overnight losses. Moreover, the insulation of the tank can protect heat for 72 hours without heat loss.
