I'm building a new shop/building this summer. I need some input on heating. I live in central South Dakota, so let's just say the winters can be cold, long, and did I mention cold? I really really want to go in-floor heat but have no idea how to do it or the costs, and besides that, since I'm only 20 years old my up front costs are already pretty high, but if I'm going to do it, I'm going to do it right! The shop part is 72'x67' with 18' sides. Any advice is greatly appreciated.
