Once we get some sunshine I'll let you know how it works. I'm heating a 24x40x9. i got the panels from my sister when we reroofed her house, not sure where you would buy them new. I do, however, know where you can get the click switch. And your circle of life theory, dead on the money. I think both you and Steve are trying to get me fired up all over again. Dang insurance companies.
