For the cost, and the actual impact of lost heat……..go with Liquid Solar Cover. Avg size pool uses 1 qt/mo, maybe less. Have compared results of heat loss with typical bubble-type solar cover and difference is negligible. Not even close to worth the hassle of dealing with on/off of the cover, plus storage. And there are a lot of better things to spend $4K on around your pool/patio than an in-ground roller storage set up……certainly be worth a try before investing that kind of money!
