So I have looked a little into Solar water heaters. I understand that they are good for letting you swim a few extra months out of the year if you use a solar cover on your pool. in OKC that would be April and Oct. Also thinking of using it as a supplement for my hottub in the winter. I have a roof that fases south.
Question is this. How durrable are these to 1" hail stones? we replace roofs here in OKC about every 15 years or so due to heavy hail. Anyone have any experience with these and midwest style golfball sized hail? Would consider getting one but not to replace it every 10 years.
