Hi Mark. I tried to send you a PM but i see PM's arent working on the Forum. I have a quick question regarding your Solar heat installation : In your writeup, you said you used a reflective backdrop for the Collector ... and im wondering why you didnt use something that was flat black in order to make the surface hotter ? Can u please explain the rationale behind this. Thanks, David.
