We are in the planning stages of building a new firehouse. We haven't settled on an exact size yet; looks like it could be either 60x125x16 or 80x100x16. What can you tell me about 1. Floor heat 2. Tube heat 3. Other options. We need the most economical to install AND operate, and of course, the most trouble free! Any suggestions? Can you tell me about your experience with the heating you are using?
