Since the incoming air is cold it would just take less of it.

I think the answer to this debacle is to put a barometric damper on the pipe that is dedicated for incoming appliance use. Then it could be set to open when it needs to.

How's the beers going down? I'm ready for another.

Dueling barometric dampers. :box:

Wow, 13 pages and we're still not sure if we've saved one chunk of coal ! :D

But, I can feel that we're getting closer to an answer. Somewhere between 3 and 4 beers a lot of things start to make more sense to me. That's about when the "beer brilliance" kicks in ! :D

I don't know if I saved any coal but I know that I'm hell of a lot more comfortable with the baro in the system then Without it. :D :clap: :dancing:

But how would it effect the draft if we filled a bag with a warm fart and taped it on? :idea:

Dumping fuel into hot exhaust gas is kind of like an afterburner!!!

:surrender: I think after 13 pages we need to surrender and have somebody to write a letter to mythbusters for them come up with the definitive answer!

They took the time to experiment with pickup trucks driving around with the tailgate up and tailgate down to see the effect of fuel savings. This is right in the same ballpark.

Somewhere back a bunch of pages someone put up a study done by the Canadians in the early 60's. It concluded that an outside air source to a stove or fireplace was useless or even dangerous. Well, I just put in a direct outside air source to my metal boxed fireplace unit and the difference is notable. I could not get any heat out of this POS even with the doors open. This is with no other devices stealing air from the house. The electric heat is not using any and the Propane furnace is setting outside on a slab. The house is not that tight I can assure you. Built by a bunch of Juan Valdez types in the 70's. Now, there is no baro in this application, but it seems that draft is maintained just fine with "outside" air supplying most of the air for combustion. The doors are not airtight, but you can see the draft coming in through the holes in the side and feel the cold air moving. The pressurization of the inside air is overrated in my opinion in maintaining a draft. The stove, fire, chimney and related components make the draft work. Houses can be to tight to allow proper draft. My friend with the Chappee stove had his next door neighbors house catch on fire, AND GO OUT. It was a log cabin and they came home to a smokey charred interior, but it was still standing and the fire was out. Try to run a stove in that place without some outside air. I also know that my VF3000 performed better when I put in dedicated lines to the boiler rm rather then just trust that it would be "made up" somewhere. Why not make it easier and control the cold air infiltration and put it right where it is needed? Plus, I had excess heat in the boiler rm and could afford to pull in some cold air.
Just my thoughts after all this high/low/neutral pressure talk.

Its possible the danger is that if a fire starts near the stove, now it has plenty of oxygen supply. Would that have make a difference in your friends cabin? Maybe - Maybe not...

I agree some houses are so tight they need a dedicated air supply. The only problem is that it can't be regulated to deliver exactly what the stove uses, which would be fine in tight house. But in a not so tight house, it just makes for more additional cold air infiltration than necessary... There isn't gonna be a one size fits all solution with all the variables involved and people are gonna do what seems to work to them. Most of the conclusions in this thread are based on rules of physics, and to prove that the physics are working would require measurements that would be very difficult to obtain. So do what ya like :) Things aren't always what they seem and sometimes things that look good on paper don't work out so well in the real world.. and I totally respect that :D

I havent read all these pages but Im given my .02$. I didnt install my Baro for the thought of conservation. I installed mine because of the 90 mph winds I get at my home. The fear of the meltdown overfire and my family sleeping at home was enough to not care if Im saving coal but in the realm of safety. I could have my air damper open a good bit and say 2 hours into my 14 hr shift the wind gets a howlin can I count on my wife waking up to close the air down a touch? Id rather not play that game. I understand this application is more for a handfed appliance but its what I have.
