Our local fire dept is deciding to try to build a new fire hall. We have some blueprints of another departments from when they built their hall. The blueprints show a tube type radient heat that hangs from the ceiling. I have been around these some and like the job they do. I also have been impressed with the in floor radient heat. Which one is more efficient to run? This is located in northern NE where the temps usually don't get much below -10 to -15, however I have seen it at -25 but that is pretty uncommon. We are probably going to use propane to heat, and we don't get a lot of calls so the doors would not be opened much in the winter anyways.
