I have a 18' x 54" Sharkline pool and would like to have a better solar heater. I currently have one of the GAME dome and I think it does help some but would like more heat. I can put more of the GAME heaters in series, or would a panel be a better option?
I do have a south facing garage roof just a few feet from the pool that I could mount on. My pump is a 40GPM Hayward.
