Unless that well were connected to a spring it would not be enough for geo thermal.

I actually have Geo Thermal installed in my house using vertical wells.
I have a 1500 sq foot ranch style house. I have a 3 ton unit and it required 3 wells 175 feet deep and the wells were only about 4 inches in diameter. The tubing goes straight down, through a U fitting in the bottom and straight back up.
I live in Iowa, we can see 20 below in the winter and 100 and humid in the summer, my system was installed in 2005 and works just fine.
