Common sense would tell me that solar would be the way to go for heating my pool, but I would like some input. My pool is approx. 15000 gal Inground,plaster. It is custom shaped with a beach area and spa recessed in the beach area. So any cover would have to be custom made. I live in central fl. But can't handle the cooler water temps. Anymore. I have a gas heater for the spa and pool but have not used it for the pool being I know it would be expensive. So is solar the way to go or what? And which solar is best for the money? Thanks for any input. Todd
