Ok, on my third year of burning and I am jeaous of all you folks out there that get like a 1/4 cup of soot after cleaning your chimney. I burn about 2 cords/year in my insert, and always get about 1 gallon of the light/flaky stuff. I've been burning mainly maple, beech and some oak, and usually let it season 1 1/2 years stacked using the cross method.
 
They never say what size cup.

I have never measured it but it is probably a 34 ounce coffee can worth or so from the 21 foot liner. Three cords a year. I care less about how much as I do about composition. Always fluffy powder, aka soot.

Ok Wiseguy....why can't one edit the poll? Dang it.
For folks questioning, say a typical coffee can holds a lb of coffee.
 
I get less significantly less than a coffee can but more than a quarter cup like some post. I've always wondered how that was even possible. I have 27' worth of liner not counting the stove pipe.

Ain't seen a one pound coffee can in many years. One of the reasons these discussions always need a point of reference.
 
I think a lot depends on the setup. I got probably three or four cups out of my insulated flex liner, exterior masonry chimner, probably the same out SIL's class A setup with about 5' of pipe above the roof, and about 1/2 cup out of BIL's insulated rigid liner in an exterior masonry chimney. I've got everyone drier wood this year, though...

Kitchen measuring cups, BB. >>
 
About a 12 oz coffee can's worth after 3 yrs burning with a straight up 20ft chimney, ~2.5 cord per year, mostly softwoods.
 
I just did my pre-season flue clean last weekend and got ~ a coffee can worth (12oz) of fine soot from ~27 feet of SL300 pipe. I usually clean once mid-season as well with the same results.
 
This is a fairly typical amount of ash/creosote from when I clean the chimney.
I usually clean twice a year, in the fall and the middle of the burning season.
I use mostly pallet wood for start-up, I figure it is pretty dry. Guess I'm doing it right.:cool:

I see part of your problem for sure. We always let oak dry, after splitting, for 3 years before burning. Beech can be burned sooner but we prefer 2 years minimum. But then, we prefer 3 years or more for all of our wood.

As for the chimney, I've already posted that we've cleaned our chimney one time in the last 5 years. Checked again this fall and it was clean.....except for a spider web.
 
- I went through 2-2.5 cords last winter.
- Primarily burned Douglas Fir.
- About 20 feet straight up

This is what I got out with Sooteater back in August. This is a 2.5 gallon pail.
