I am trying to figure out if I might build a small addition to the house for a boiler instead of the basement. It appears to have the benefits of no wood in the house and not having to go outside to tend the fire. No pipes to bury in ground and shorter runs. But my questions are: Do I need to deal with any code restrictions in an addition situation? I am thinking that I can run a stove pipe out the addition making sure that it is 10'+ away from the house but will that give sufficient draft for the boiler? Any need to plan for fresh air for the "boiler room"? I am thinking Tarm but still looking for the $$. I noticed that EricV mentioned he has something like this. Are there others who have a house addition boiler room?
