* Patent design, pipe-in-pipe structure makes heat transfer directly in pipe, higher efficiency than normal collectors, especially suitable for freeze area.
* The outlet pipe is now positioned at the back of the collector to allow flush installation of 2 or more collectors and keeping pipe work out of site.
* The efficiency won't drop down with time goes by. One or several tubes broken will not influence system work.
* Solar keymark certificate.
