Thought someone might find this interesting. My home brew solar pool heater. The coils are made from 100 foot rolls of 1/2 inch poly tubing from Home Depot Irrigation dept. The frames are 2x2 aluminum extrusion scraps I had. I think it will stack up against any professionally made system of equal size. Cost about $300.
