I'm planning on building a solar water heater for my Intex 15' AG pool. Most of what I've read recommends using black pipe as black will absorb heat better. But I keep thinking of my solar shower, which is clear on top with a black background and does get water very hot. With that in mind I'm wondering about clear tubing, spray painted black on the back and placed on a black background.
Has anyone done this or does anyone have any thoughts about which way would work better?
Thanks, Gomez
