Bob---I had a look at the solar water heaters. They are approx 3'x12' and flexible, kind of like big rubber mats. They link together...I know you can run your water main through them to preheat the water before it goes into the water heater. I've heard of people setting soft copper tubing in a basement concrete floor and having a solar pump circulate the water from the roof through the floor--really puts some heat in the house in the winter. There are 4 of them if you want them but he won't store them forever..
