Every added baffle reduces the draft by some degree. if you have plenty of reserve draft this may not be a concern, but if draft is even occasionally minimal, it is a very serious concern.

yep, every install is it's own beast.
BTW Larry, have you gotten any closer to a decision about a new heat appliance ?

HA !! exactly, and just the reason I don't have one any more. with my draft and the baro in the living space I was pulling more air into the house thru leaks and up the flue than I was heating.hotblast1357 wrote:I can suck a cat through my baro lol

I was considering a fresh air intake that way its not pulling so much through the house

if the install in your avatar is still accurate and your unit is in the basement, you could consider putting a dryer tail thru the box plate with the usual outlet ( with flap )on the inside. screen the tube on the outside to keep bugs out.
this way the negative pressure of the stove draw will control how much air can come in AND it will come in and mix with the rest of the warmer air and not have much impact on comfort levels.

That's what I was thinking of, just running it between my floor joices over to the top of the stove, I am just trying to weigh the pros and cons of it and if it would make a big difference or not

depends, are you using forced air for heat distribution ?
is so, since your air make up would be down stairs you might create a full positive pressure condition upstairs and shut down pretty much all infiltration up there.

I have a full cold air return so I don't think that would happen

kind of, except to my thinking................. since you would be getting most of the air that goes up the chimney from outside / downstairs, the circulation system would be doing just that, circulating at a pretty much constant pressure, thus less infiltration.
maybe ? maybe not.

Less infiltration upstairs would be better wouldn't it?

well yes. for alot of us if we could close up or cancel out more or all of our infiltration sources we would use less coal, save more money, be mo beta .
the issue is, will the approach we are discussing actually accomplish what we hope ?

I'm at average 50 lbs a day so anything less be awesome! I already consider 50 a day to be efficient

Haha... here we are with the air infiltration dilemma again lol.. interesting issue and its fun to think about all the physics going on with it.
Personally, I don't believe in a dedicated combustion air source and I'll explain. Your home like the chimney has its own stack effect happening. This stack effect in the house creates a neutral pressure plane. This plane under normal conditions resides horizontally somewhere in the middle of the house. Its where pressure in the house equals the pressure outside. Above the plane, there is positive pressure pushing your home's heated air outside thru every nook and cranny, crack and gap that it can find. Below the plane is negative pressure causing cold air is entering the same way.
By adding another air source, the pressure plane adjusts to a lower position in the house. This increases the positive pressure at top of the house. Since pressure dictates volume flow, it forces more of your heated home's air out at the top. This effectively creates a faster turnover of your home's air.
I believe that a dedicated air source is only needed if your chimney is drafting poorly.
But that's my own view of the whole can of worms..
