I need some professional HVAC help. I'm in the process of designing a workshop at my home. Primarily it will be used for woodworking but occasionally I will work on my vehicles, lawnmower etc. I am planning to put a finishing room for wood finishing within it. What kind of heating system would be recommended. I believe in the floor radiant would minimize dust transition into the finishing room but I have been unable to determine the operating cost of in the floor radiant versus say gas-forced-air. I realize that the initial cost would be higher. Any recommendatons based on professional experience?
