Features:

1) Closed loop with copper coil for pressure, working pressure 6 bar, Max resistance 12 bar.

2) Reliable and efficient twin-glass solar tubes

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 the copper inlet /outlet with tap water piping directly. Water is feed automatically by the water pressure. The vacuum tube absorb the sun energy and transfer the heat to the tank .Then tank water warm the water of coil in a short time.

2) Solar absorption: solar radiation is absorbed by the vacuum tubes and converted into heat.

3) Solar heat transfer: The tank water conduct the heat from within the solar tube up to the coil.
