I think I've decided that solar probably isn't going to work for me too well. We have a garage roof that would accomodate solar panels, but I don't think it gets enough sun when the trees are leafed out.

I would like to raise our pool temps by at least 10 degrees in the shoulder seasons. We have a propane tank that connects to our garage furnace in the winter, and that would be available to me for a heater the rest of the year.

Does anyone have any experience with above ground propane heaters? Obviously I'm looking for a decent bang for the buck.
