I am currently building a 40x80 pole building and am considering floor heat. I live in Indiana and we have cold winters here. I am planning on storing hot rod/collector cars in this building and will occasionally work in the building. The contractor is going to start bringing in the fill to get the floor up to grade in a few days ,so I need to decide on the heat soon. Can someone here help me spec out a system or lead me in the right direction. The building will be insulated and finished on the inside. The ceiling height will be 12 foot. Thanks in advance. I promise some pics in the gallery section soon.
