Flat plate pressurized solar water heater is a device which highly efficient vacuum tube absorbs heat from sunlight and heat pipe transfers heat to the condenser end of itself. Condensor indirectly contacts with water through a copper cap and it boils water by releasing heat gained from vacuum tube.
Advantages
1) Adopts the best conduction performance metal- heat pipe (copper).
2) Start up quickly, heat pipe transfer the heat energy into the storage tank in one direction
3) No water inside the evacuated tubes, the solar water heater can still in service even with several tubes breakage
4) Can be used all year round in the cold climate
5) works with high pressure, so do thewater it produces
