If so please post some pics!
Can you use pex in place of copper or SS tubing?I really want to make one of these for my pool. Living in New England really only gives you 2 months at the most. You end up doing all the work and spending all the $ for 2 months! There are 2 companies i found that make these. The main thing is the coils have to be S.S. not copper. The chlorine will affect the cooper and turn pool green. If you have a 20x40 pool you need like 120 feet of coils inside heater. 120 ft of S.S. tubing is not cheap.
