Having a new 16×28 ingound put in soon, and im thinking about adding solar heat. My roof which is 2 stories high gets full sun 80% of the day. Im curious if im being too optimistic thinking I could gain atleast a month before and after a non heated pool? E/l is ridiculously expensive here, so I wont go near a heatpump, and gas is not an option. Thoughts? Anyone here in notheast with this setup? Thanks
