QAL integrative pressurized system is a renovate model for the solar hot water, which adopts advanced heat pipe technology, combines heat pipe solar collector with pressurized tank to form a compact model.
Solar heater features
1)Highly efficient absorber of high performance with daily average efficiency over 70%
2)Start up quickly, heat pipe transfer the heat energy into the storage tank in one direction
3)Withstand pressure of 6 Bar, can be connected directly with city water
4)No water inside the tubes, the system can still work even with several tubes breakage
5)Simple structure, easy to assembly and install
6)Can be used all year round in the very cold climate
7)Can be used together with Auxiliary electric boost
8)Long service life, can be used as long as 15 years
Solar heater working principle
1.The solar heater 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 pressurized 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.
