Just bought my pool and trying to think of things i need to look into before we have it installed.. I want a solar heater, but I really don't want to have to lay them out on the ground (panels) or try and find a way to mount to my roof of my home.. Any thoughts on the solar Arcs or Solar Pro coil looking units that sit on the ground but don't take up a ton of space and are not so noticeable they are unsightly? You can hook several together to heat up the pool more quickly depending on size but it seems everyone is going for panels and I am not sure if it's just because that is the standard or that these other types or known to be not as good? Thoughts? Suggestions?
