Stainless steel pressurized solar water heater

The system is pressurized. Keep a constant temperature of water in the tank.

Specification:

1.inner tank: SUS 304-2B food grade stainless steel 1.2mm--1.5mm;

2.outer tank: SUS 304-BA stainless steel 0.31mm--0.41mm;

3.Bracket: Galvanized steel with powder painting 1.2mm--1.5mm;

4.Heat insulation layer: polyurethane,can keep the water temperature last for 72 hours 

5.vaccum tube: high borosilicate 3.3 ; coating:ALN/ALN-SSCU

Working Principle:The pressurized water tank has no exhaust hole, therefore, it must bear the pressure came from tap water and hot water. When use, the hot water comes out because of water pressure. Vacuum tube absorbs solar energy, and conductive copper pipe transfers the heat into the pressurized water tank. In this case, the water inside the tank becomes hot. No water in the heat pipe makes the whole system could bear pressure.
