pressurized solar water heater Decription:..
Working Principle:
Pre-heated solar water heater also relies on the natural circulation of water between the collector and the tank (that is tubes absorb solar energy, and heats the water inside the tube, hot water rises, cold water flows down).
It differs from compact non-pressurized solar water heater because it gets a copper coil inside the inner tank. The hot water rises from the tube into the tank, and heats the copper coil and finaly heats the water inside the copper coil. Therefore the water tank is just as heat storage tank. So the hot water we use is actually from the copper coil, it'is more clean, and even drinkable(as the copper can purify the water. ).
Specifications:
1)inner tank: Stainless steel(SUS304/2B) with 0.5mm thickness
2)Outer tank: Galvanized steel alloy with 0.4mm thickness
3)Tank capacity: 150L/200L/250L/300L
4)Vacuum tube: ¢ 58mm/1800mm;
5)Copper coil: : ¢ 12mm/thickness 0.8mm
6)heat insulation layer: Polyurethane with 50mm thickness
7)Certificates: CE, ISO9001(2000), CCC, SGS
8)Warranty: 5 years for full system.
