Wonder if this has ever been tried. It's for next year's season.
I had solar covers for many years. I found they gathered and retained heat very well. I now have an auto-cover which is wonderful for keeping the pool clean and convenient to open and close but worthless at retaining heat.
I was thinking of having a solar cover floating on the water, coming off of a reel that would be at the opposite end of the pool than the auto-cover. The loose ends of the solar cover would have to be "tethered" with easy disconnects to both ends of the pool.
So, would a solid auto cover slide over a solar cover? I'm thinking it would put a lot more drag in the system that it wouldn't be practical and it would over-stress the auto cover system. Anyone have any pros or cons?
