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.

Features:
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
