Pressurized solar water heater 150L Solar keymark, CE, ISO Red copper heat pipe, transfer heat quick 58-1800mm tube

1. Working principle:  

The pressurized water tank has no exhaust hole, therefore, it must bear the pressure coming from tap water and hot water. When use, the hot water comes out because of water pressure, vacuum tube absorbs solar energy, and conductive copper pipe transfer the heat into the pressurized water tank. In this case, the water inside the tank becomes hot. No water in the heat pipe makes the whole system can bear pressure.

3. Features:

   1) There is no water in the vacuum tube, so it can be working even have an tube broken.

   2) The red copper in the inner tube, the heat transfer more quickly.

   3) It is a closed loop, so the heat can be preserved for a longer time.
