I have no idea what the weather is like in NC where you are going but here in ND it can get cold. I put AL-PEX floor heat in when I re-poured the shop floor. It has considerable advantages over any kind of forced air. Since the heat comes from the floor there are no cold spots, with an air temperature of 60 degrees and a long sleeve shirt it is comfortable, and when you open an overhead door, all your heat doesn't escape.
