Product Description

Compact non pressure solar water heater relies on the nature circulation of the water between solar tubes

and the water tank. Thermosyphon systems work on principal of heat rising. The water enters in 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 during 3 days without heat loss.
