Another quick note....there's a recent thread on placing your boiler in the garage. I debated this myself quite a bit...and everyone has a different take. But ask yourself carefully how you feel about a roaring fire in your garage in the event of a mishap....like gasoline spill, sawdust in the air, etc. Many codes forbid this apparently, yet around me I know many people who heat their garage with an old, inefficient wood stove/furnance. Sure would be nice to walk out in the skivvies to tend the beast, but I know for me, I'd be constantly concerned, so mine is in its own dedicated building. Even better, would be nice to know all the lost heat went into the garage. But when the kid is working on the minibike and the gas line is accidently disconnected and the tank dumps on the floor.... Now I'm personally a bit anal on the subject, as I had a brother die in a house fire 35 years ago when just the above happened, albeit with slightly different circumstances. Culprit there was a gas fired hot water heater...that ignited the gasoline as it ran towards the floor drain by the hot water heater. Personally, I hate natural gas.....yet about 5 billion people on Earth use it everyday. And if they ever drill for marcellus shale gas on my property, perhaps I can actually retire someday....
