Flat panel solar water heater with 2 flat panel solar collector,there are water inside the panel.

Flat panel solar water heater

Working Principle:
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. Flat panel absorbs solar energy, and conductive copper pipe transfers 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 could bear pressure.
