You know the fall air is getting crisp when the questions about heating the shop come out.
IDAGS on some garage heating options, with the nod seeming to go to the Hot Dawg and Reznor units. While installing my new water heater today with the help of my next-door neighbor (a plumber/HVAC guy), I asked him if he knew anything about these particular models. He didn't, and I explained how the Reznor model I was looking at uses outside air for combustion. I'm not so worried about exploding dust as I am about the precat lacquer I intend to spray. He said that any 90% efficient furnace uses outside air for combustion and that the combustion chamber is completely sealed. He could get me a great deal on a small Carrier unit (by small he means only 80K BTU...I've got him looking for something in the 45K range). Does anyone know of a reason I couldn't use a setup like this? I suspect the size will be somewhat larger than a Reznor, but I can live with that.
