From the Web site of Energy Concepts, located in Hudson, Wisconsin:

One hurdle on this project was convincing the sub-division association that the solar panels would not take away from the development’s overall aesthetics and that it complied with existing covenants, which it did.

This is a custom-designed combination domestic hot water and in-floor space heating system.

The homeowners received $2,500 for the project from a Focus on Energy Hot Water Grant and another $3,500 from the Solar Space Heaitng Progam, a program of utility members of WPPI Energy.

Two 119-gallon tanks (below) hold the solar heated water until it circulates under the floors to heat the house.
