I don't have the room in the yard or the roof for the 4 solar heating mats 4 - 2X20 for a 16 X 32 15,000 gal IG would need. SOOO my thought is how about laying them on top of the solar cover to provide buoyancy and using 2 returns and some flex to provide the flow, the ends could flow right off or be controlled several different ways and and tie it all together so I can roll it up on the reel when we use the pool. During the day in full sunlight warm the pool. Looking for reasons as to why this wont work.
