I would like to extend my swimming season. I was using SunGrabber panels on a custom built rack, but it was ugly, the panels didn't lat flat etc etc, so I took them down. I can't put anything on my roof because I have a solar electric system, so I am looking for a cleaner solution that takes up less space and found these.

(goes to Amazon)
The numbers I dug up on the interwebs state with 1 of these I can gain 5deg in 10 days (assuming 10hr@80deg). And the reviews I have seen indicate they work pretty well if you plumb them properly.
Does this sound plausable, and is it a decent increase? Anyone have any experiance or opinion on these types of solar collectors?
