Heat transfer through cement Answered
I have a garage on top of garage because my land is on a hill. The lower garage is all concrete all the way around including the ceiling. The floor in the upper garage is the cement from the roof of the lower garage. I want to heat the upper garage, but I know the floor will always be really cold because it is cement and the lower garage is not heated. The lower garage does stay quite a bit warmer than outside temps.
My question is this, If I heat the lower shop, will the floor in the upper garage and the upper garage that is insulated be warm as well? Or am I better off just heating the upper shop and having a cold floor? I spend a lot of time in the garage and would like it comfortable when I am in there.
