Features:

1) Pressurized tank, working pressure 6 bar, Max resistance 12 bar.

2) Reliable and efficient twin-glass solar tubes

3) Copper heat pipes for rapid heat transfer ,No water through the tube, So it can good working in winter without freeze.

4) Easy plug-in installation.

5) Free maintenance.

6) Stable solar conversion during the day.

7) Ideal for home applications.

How it works:

1) Connect with tap water piping directly. Water is feed automatically by the water pressure. The vacuum tubes absorb the sun energy and transfer the heat to the tank via the copper heat pipe and the water temperature of tank is gradually heated.

2) If the water is expand and pressure rise to more than 6 bar. The PT valve will release automatically.

3) The electric heater can be operated for backup heating.
