Detailed Product Description

Specifications:

Solar collectors are always connected with existing heating supply device, which
is most important part of solar water heating system. The selective coating on the
inner cover of the evacuated tubes converts solar energy into heat energy andtransfers heat to the heat pipes. The heat then passes through the heat exchanger.
