Geothermal vs spray foam insulation
My wife and I are in the beginning stages of working with our home designer on our house plans. We have been discussing the use of some newer methods to insulate, heat and cool the home. I am not sure the up front cost of using both spray foam insulation and a geothermal heating/cooling system makes sense. I am not sure I could recoup both of the extra upfront costs and may choose one over the other.
Has anyone used these systems in a new home? If so which one do you think we would get the most return for our investment on?
