Can a geothermal heating system still work in climates with frozen soil part of the year?
Absolutely! That is the exact environment where we are thriving in. Winters in the Gallatin Valley are very harsh, and the soil is probably frozen for over half of the year. But because the ground loops are installed below the freeze line (usually 4-8 feet in depth, depending on soil type), the changing temperatures above ground do not effect the heating capabilities.
