Hello all,
I've made an attempt to seal up my old house pretty well, but it's nowhere near the point that my furnace requires a combustion air source. (To be honest, though, I've actually never tried turning on the bathroom fan, the dryer, the water heater and the furnace to see if I have any back draft).
I've been thinking that maybe it wouldn't hurt, though, to provide one anyways. My furnace is only 80% efficient, although it is relatively new. My thinking is that furnace will pull air directly from outside instead of pulling the cold air in through the living space.
I figure that the outside colder air would have more oxygen (thus more efficient) and the savings from not heating cold air infiltrating through the cracks would also be beneficial.
I would like to put in maybe a 2 or three in PVC pipe to the outdoors, but I'm concerned that this would be able permanent source for drafts when the furnace isn't on. How could I shut it off when not needed?
Thanks,
Jason
