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:
Sun's ray will be collected by absorbers, then radiation can be transformed into heat energy by selective absorbing film. Heat pipes conduct the heat from the tube up to the header pipe. 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.
