Solar Water Heater

We had a solar water heater installed last month. It took almost 3 days to put the system in (complete with crawling around in our tiny attic). It runs antifreeze through a solar collector on the roof. There is a pump that moves the antifreeze through a heat exchange coil in the hot water heater when it is hot enough. The system has an electric backup, but we turned it off. The system produces hot water every sunny afternoon. I only turned on the electric backup one cloudy Sunday afternoon when I did three loads of laundry and ran the dishwasher. So far it works fine running it this way, although I expect sometime this winter we may have to keep the backup system on.

I'm working on a Quilt of Valor. I've been making star blocks from one of the Nickel Quilt books by Pat Speth.
