This is my first post and thanks in advance to all of those so willing to share their knowledge and experience. I look forward to the day when I can contribute more to the forum. I couldn't find my specific question in my forum searches, so I hope I'm correct in starting a new topic rather than attaching to one of the earlier solar threads.
We just moved into a Tucson home with 9,000 gal inground pool, our first pool experience. The existing solar panels are deteriorated, leaking and poorly installed (roof leaks) so we are re-finishing our flat roof and installing new collectors. We're trying to evaluate collector panels (heliocol) vs the spiral/coil type like those manufactured by SolarTech. There's about a $1,500 price difference with heliocol panels more expensive. We've heard the spiral/coil collectors dismissed as "garden hose on the roof" but in my experience the simpler designs are often the best. Does anyone have experience with either collector type that can help our decision?
