Anyone have any knowledge or opinions on the effectiveness of solar heater
panles for swimming pools? I have a 24' round pool that tneds to get no
higher than 78F during the hottest points of the summer. Lots of big old
miserable trees shade the back yard during the time that the solar cover is
on. Will one of these solar heater panels make any appreciable difference
for my pool? Or are they a gimmick? I'd kind of like to be able to get it 5
degrees warmer than it is. Any ideas would be appreciated. Thanks.
