Delta Sun Stainless Steel SWH

HOW DOES THE NON-PRESSURE SYSTEM WORK?

The non-pressure gravity feed complete system consists of a vacuum glass tube collector, an insulated storage tank, feedertank anda stand. The evacuated glass tube are filled with water and exposed to the sun. Thus heating up the water in the glass tubes. As the specific gravity of cold water is heavier than hot water, the hot water in the glass tubes starts to rise in the insulated water tank and the cold water in the tank sinkinto the glass tubes. As this cycle is repeated, water in the solar water heatergets heated. This process is known as thermo siphonand is based on natural convection.
