I am planning to install (DIY) solar collectors on a south facing low pitch shingled roof above our inground pool. The roof is 23 x 13. Pool is 18 x 34 kidney shaped vinyl liner. Approx 600 sq ft of surface area. I have a 175K BTU natural gas heater and would like to use the solar to supplement. The roof gets full sun and unfortunately the pool does not. Goal is to increase temp during regular swim season and not necessarily extend our season. I inquired with powermat (Hot Sun Industries) and have also seen several vendors on ebay and the internet pool suppliers. Powermat recommended eleven 2 x 12 collectors. Any help from members who have gone this route would be appreciated. I do plan to install this system myself. Some questions that I would like help on are.......
1) Which brand collector?
2) Recommended supplier or dealer for the DIY'r?
