The Priciples:
The series Compact solar water heater for residential use with hot water storage tank employ the natural convection phenomenon called
"thermosyiphon" which results in hot water being lighter than cold water.
The water heated in the tubes rises through the solar collector to enter the strong tank, while the cold water at the bottom of the tank folws into the tubes creating continuous circulation. The continue as long as the sun is heating the collector.

Features:
It is a solar domestic water system comprising all-glass evacuated tubular collector with water-in-glass manifold.
It is non-pressuried system. It has airvent connected to the air in the tank. The pressure is less than 1MPa.
