Working principle:

The vacuum tubes absorb the solar energy, thermal energy is transferred to the water tank through the superconducting heat pipe and heats the water in the hot water storage tank. When use hot water, open the hot water valve, hot water outflow under water pressure.

1. Inlet & Outlet: 3/4 inch    

2. Inner tank material: SUS304-2B Thickness: 1.2mm
3. Outer tank material: SUS or galvanized steel

1. Overcome the defects of non-pressure of ordinary solar water heater.

2. Resolve the phenomenon that water temperature is not stable caused by the un-match between  the natural pressure and cold water pressure changes of the non-pressurized solar water heater.

3.Overcome the problem of lower installation location and not enough water pressure;
