Special designed for the separate pressurized solar heating systems. It's easy to combine with existing water heating systems. This solar collector is of excellent figure, reliable performance, low maintenance, convenient replacement. One or several glass tubes broken will not affect the operation of the whole system.

Working Principle:
The vacuum tubes absorb the solar energy and transfer into the heat energy, then pass it to the U pipes. U pipes conduct the heat to the water.. The circulation pump makes water circulate every now and then. And Each time the water circulates through the header pipe, the temperatures is raised by 5-10 degree. There is no water in the vacuum tube, so the tube will not break in the winter. It can be still operate in the event of occasional tube breakages.
