   My diy system uses epdm roofing rubber for a heat sink and it works very well. I am pretty sure I posted info on it on this site, maybe even with pics. It was cheap for me since I used scrap rubber left over from a job. you may also check your local scrap yard for parts. Where I live I can have anything I want out of the scrap yard. I just pay by the pound.

Excuse my ignorance but what is epdm roofing rubber? By heat sink do you mean absorber plate? If so, how do you assure good thermal contact with the piping? It seams that rubber is not a very efficient thermal conductor so it wood need to conduct the heat through the air by convection inside the collector which is not what we want from and absorber plate. Did I miss something in your post? Martin
