Compact pressuirzed solar water heater working principle:

1.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.

2.Vacuum tube absorbs solar energy, and conductive copper pipe transfers the heat into the pressure solar water heater tank. In this case, the water inside the tank becomes hot

3.No water in the heat pipe makes the whole system could bear pressure





Pressure solar water heater features

1.Adopts the best conduction performance metal- heat pipe (copper) 
2.Can be used all year round in the cold climate
3.High efficiency, rapid warming. Heat pipe in vacuum tube could transfer hot energy to cold water in pressurized water tank rapidly
4.The whole pressure of the system is up to 1.5kg/M2, the inlet could connect the tap water directly, the max pressure can be 0.6Mpa 
5.No water in the tube, one tube broken don't influence the system working 
6.The design for inner tank is reasonable and scientific, which could hold 100, 000 times fatigue test without any damage
7.Dual-purpose brackets for both flat and inclined roof 

8.The system is pressurized,it keep a constant temperature of water in the tank, avoid the problem came from water level controller malfunction which could cause water flow out
