Maybe the wind increases the draft in the chimney?

Absolutely, the chimney never drafts when it’s at idle, goes positive for a little when it first fires up, then goes to maybe .01 when fire is fully established, but with the wind blowing like it was, draft will read .03-.06 all the time.
But... with the fan off, port door is open, so more draft would pull more air over fire and technically kill it more??

I doubt there is any affect on the fire at idle, just under power. Could be, but I'm not betting money on it.

I can see the validity in this for the case where a barometric damper is overwhelmed by the wind and can no longer hold draft to its set inches of water column, even when wide open.

I do not run a barometric dampener anymore. Took it out before this season.

It's not the wind chill that increases coal consumption...
But the pressure differential that increases the amount of infiltration...
Causing the increased need for fuel to warm the invading cold air...
Wind chill is for bare exposed skin...
So if you like to go outside naked...
It's important...
I worked outside for a bit making snow at Killington in VT...
The proper clothing, keeping fully covered and staying dry...
Did not matter what the temp was...
Or if the wind was blowing...

Over the 2 years that I kept detailed records of coal consumption vs outside temperature, the day I burned the maximum amount of coal was not on the coldest day of the season. Instead, it was a day with a bitter temperature and a stiff wind from the NW.CapeCoaler wrote: ↑Tue. Jan. 15, 2019 11:15 amIt's not the wind chill that increases coal consumption...

That was what happened in the previous house of mine...
Down by the beach...
When the wind picked up...
I could easily go thru 120# in 24 hrs...
In a 1000 sq ft cottage...
When it was 'only' 20* outside...
It could get down to 5*, still windy and eat 160#...

So I am guessing that HDD's don't account for the wind, do the HDD figures account for sun vs cloud cover?
We have the same increased coal consumption here with wind as others see. Our climate is not nearly as cold as the others here so the free standing stoker does fine 95% of the time. But I know I will need propane furnace run time to help the free standing stoker keep up in two conditions. Either with night time temps around 5* & no wind or night time temps in the teens with 15+ mph winds. When temps get down to 10* with no wind the stoker keeps up just fine.
Of course a well insulated, draft free house will perform better than a house with those issues, but even in a well insulated house the windows provide a relatively low R value area of temperature exchange.
I believe that is the issue at my house. Though it had all new fiberglass insulation in '93 and has tar paper and tyvek both on the sheathing to cut drafts, we have a lot of windows which is a lot of square footage of low R value compared to the insulated walls and ceiling. One kitchen wall alone has an 8' double pane slider equating to ~50sqft of at best R3 or 4 insulation value....lots of temp exchange there!
The flip side of all those windows is that during daylight, if it is a bright sunny day we have a lot of solar gain and the stoker will remain in idle mode even with temps in the 20's on non windy days.

My biggest problem is my windows and doors.. even though the house was built in 2017, they put cheap terrible doors and windows in.. like this window in the 2nd bedroom, the bottoms of the frames are to wide, and the window gaskets don’t even touch.

The windows & doors here were all replaced in '93. I used Andersen 400 double hung windows. The double pane seals are still performing well 25 years later. There are only two that get a baseball size area of condensation between the panes when temps drop to single digits. I've used a Pella, Andersen 200 and a couple custom manufacturers over the years in different rehab projects and these 400's have held up the best (and they were the most expensive too).
I have a flir attachment for my cell phone, I'll have to get outside for a few pic's tonight to see the contrast of wall to window heat loss. Maybe the two bad windows will show up differently on the flir too.

We're finally in line to see our first sub zero degree day here soon also. Nothing like what is shown above though. We do have this upcoming Saturday calling for 8" to 12" of snow though. The Akron Beacon Journal says snow might even hit 30" in Akron. See the current Akron Beacon Journal weather video (attached). Akron is roughly 20 miles east of me.

It’s gonna be -10 here tonight too, and we are looking at the same snow storm this weekend, possibly 2’ in some spots.
