Anyone hear of this and know of it's reputation?
It's a solar heating system that you install in your pool deck. You pour the concrete right over it. I thought it would have a good chance of cracking when the concrete cracks, but the website says that it will actually make your concrete stronger and less likely to crack. It also says that they haven't had to make a single repair since they started in 1982.
I wonder how well it can actually collect the sunlight though with a layer of concrete over it. But maybe?!?!
