Sunstar high pressure stand alone model is a new type of solar water heater which adopts advanced heat pipe and all glass vacuum tube Technology. 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. The available size of the tank ranges from 150L to 250L.

Features:

Pressurized solar water heaters with extra inner storage tank as heat exchanger, heat exchanging takes place in advance and continuously whenever temperature difference exists (between two sides, i.e. inside and outside the heat exchanging inner tank) and plenty of ready hot water is stored in the extra heat exchanging inner tank.

1) Excellent hot water output performance
2) Large flow rate (3/4" interface)
3) There is no water hammer and no vibration when output is shutting down
4) Working pressure: 0.6MPa
5) Test pressure: 1.5MPa
6) Low pressure jacket configuration eliminates worry of over heating which normally happened to pressurized systems
