solar water heater description
1. All machine mental parts is stainless steel and galvanized steel
2. Inner tank: Ø360mm/SUS304-2B/0.41mm. Outer tank: Ø460mm/Galvanized steel/0.32mm
3. It use 50mm of high density polyurethane foam for insulation layer. Heat preservation: 72hours
4. Vacuum tube: 58x1800mm 1.6mm or 2.2mmthickness ALN-SS-CU coating
5. Copper Coil: Ø12mm with thickness 0.8mm
6. The bracket is in line with structural mechanics, very stable and solidly build. Dual-purpose for both flat and inclined roof.
7. Output water temperature is stable, so it is very comfortable and safe to use
8. Easy to operate, reliable to use and intelligent to work
solar water heater advantages
1. Heat exchanger connecting with city water directly to get high pressure hot water;
2. Hot water from heat exchanger is instant and clean;
3. No need to install heater on roof top for pressure hot water outlet;

Working principle:
The vacuunm tubes with heat pipe absorb solar energy and transfer heat into the tank.But the water in the tank is not to use,the tank just as a storage tank,one copper coil is installed in the tank as the heat exchanger.When water flows into the copper coil,it absorbs the hat of the water in the tank via coper coil.
