Well we're going to do it.....We have made the decision to have a Solar Furnace installed on our house at the end of the month.
We live in the upper midwest we have about a 6 month heating season.
It will be installed on the south end of our house. We have had our house evaluated for solar exposure and it is 85%.
We get a lot of cloudless sunny days in the winter. I'm hoping we get nice warm air blown into the house.
I learned from Steven Harris this may be the best way to utilize solar.
We live in a typical suburban neighborhood. I wonder what the neighbors will think? The furnace will be about 8 feet square. The ducting will exhaust into our lower living space in about the center of the house.
I'll take photos of the install and pass along my observations.....
