“Solid Wood: All About Chopping, Drying and Stacking Wood — and the Soul of Wood-Burning” This best selling book by Lars Mytting highlights a passion for firewood and inspired a TV program in Norway about cutting, stacking and burning firewood. The TV program, on the topic of firewood, consisted mostly of people in parkas chatting and chopping in the woods and then eight hours of a fire burning in a fireplace. Yet no sooner had it begun, on prime time on Friday night, than the angry responses came pouring in. “We received about 60 text messages from people complaining about the stacking in the program,” said [Mr.] Mytting .... “Fifty percent complained that the bark was facing up, and the rest complained that the bark was facing down."

As someone who has cut and stacked firewood, and burned about a gazillion fires in the fireplace, I can relate to this passion. The bark goes up by the way.

Why does it go up? Because you said so?

I put mine the side, and then when it dries, I peel it off and cook it with butter, the way God intended.

The game is seasoning one's wood so that it's nice and dry (after a year or so) and burns efficiently in the stove. Some must believe that having the bark up will help the wood to repel water and dry more quickly.

I'm of the "howsoever contributes to the stability of the pile"-type stacker, though I secretly envy those sexy conical piles that one sees here and there.

It goes up because the bark keeps rain from soaking into the wood, presumably speeding the drying/seasoning process.

It's not perfect, but if the wood faces up, rain soaks straight in. The bark helps shed quite a bit of it.

I guess bark up kinda makes sense to an outside non-chopping observer: Bark protects trees, trees are rained/snowed on, therefore bark would protect chopped wood.

Bark up might be an advantage if you're going to leave it out in the rain. Otherwise, it's not important.

Also, you can get the wood drier much quicker if you split it down into pieces about 3 inches in diameter - I find that wood I cut in the spring and summer is ready to burn by the winter that way.

I think the most important factor is stacking it so that it doesn't fall down, especially on top of you. Around here the top of the pile usually has some corrugated roofing material on top- presumably this sheds water even better than bark.

And I'm so envious of these 10-20 cord stacks of wood I see in other people's yards.

Bark orientation becomes most critical in soggy climes and where the piles won't be covered. But everyone I've ever stacked with goes with bark up, for the reasons given above.

I've spent days in the woods alone with a bow saw cutting up fallen trees, where a day's labor might yield a cold week's worth of wood. But from this I would feel a depth of satisfaction never experienced in any other pursuit. It's a very primal thing.

If you're air drying wood - I mean really air drying wood, with sticker stacks and moisture meters and stuff, the maxim is one year per inch of thickness. If you fail to paint or PEG (pdf) the ends, though, you'll get checking that goes in 3-6 inches in two or three weeks. The physics of mass drying of wood is going to be a little more complex, but really, I think this is arguing about which side of the crouton it's better to pet.

Typical Norway. People in the East (where the climate is drier, and it's generally sunnier) probably swear that bark-down is the way to go, as it probably allows the wood to dry quicker. In Vestlandet (where I live) they probably swear that bark-down is the way to go, in order to shelter the wood better from the rain (somewhat humorous, since it's typically horizontal rain). Let the holy war commence. I do what most people actually do and throw it in mesh bag to dry (bark everywhichway).

FYI, as a person living in Norway with first-hand experience with cutting down trees and splitting them into firewood, I can tell you for a fact that I have never once seen nor heard of someone actually doing this with an axe. At the rate the Norwegians burn wood, there is no way to split wood with an axe fast enough to supply your demand.

If you want serious controversy, you could observe that most Norwegians do not know how to start a fire in the correct way. Suggesting a way other than how they learned how to do it as a child is simply heresy.

If you want to make your hard-earned wood last about twice as long, you should read up on gasifying woodstoves. Not only are they pretty, their combustion efficiency is about ~80%, as opposed to ~40% from a plain single-pile stove. If your chimney is smoking, you're throwing unburnt fuel away.

Holz hausen are pretty great.

I tried building one of those a few years ago. On my first attempt, I got the walls built halfway before they collapsed in a cacophonous radial explosion of firewood. The second time around I reduced the scope a bit and ended up with something halfway decent.

I wouldn't recommend building a holz hausen unless you're planning to let the wood sit drying for a few years. They're very laborious to construct and even harder to take wood from without toppling the whole thing. If you're just laying in firewood for the winter, it's easier to just stack it up in a boring old rectangle and put a tarp over the whole mess.

Does bark up/bark down matter if you're tarping your pile?

I've been in the stack for stability camp so far, but am willing to make changes if necessary. This winter's wood spent a good long haul under a heavy tarp, and is burning just fine.

I do a lot of stacking. But I will totally recommend the volunteer splitter who wants to get in shape for a challenge race and offers to cut rounds with his lovely, lovely ax. Thank you, Norwegian wood karma!

The layer on top is always the layer you are about to use. It doesn't help you much if they wood in the middle of the pile is nice and shielded by the top layer and the wood you're trying to burn is soaking wet.

The bark goes up by the way.

There's a passage in the book where Mytting explains how different areas in Norway use different practices and how that's liked to the climate.
"New research shows that the drying process is completely marginally faster when the bark faces down, but the difference is marginal...no matter which it is important to make use of the water-repellant properties of the bark in unprotected woodpiles...logs with the bark on top function like a roof...downward pointing bark in the lower layers protects the wood against humidity from the ground...
These factors explain why Norway has formed two schools ... close to the coast the wood is stacked with the bark facing up, further inland they put the bark facing down. The reason is that inland, the [should be "most"] precipitation comes down as snow, and since one hasn't the same problem with driving rain as along the coast, nor the same good drying conditions as given by the winds of the coast, the wood does in fact dry faster with the bark down."
Slop-translated from the Swedish version, p. 109.

The book is a success even here. For us, house owners who exclusively heat with wood (even the warm water...), it has actually proven to be genuinely helpful. It has made that I re-ckecked and refined every single step in the (quite substantial) chain of actions around my wood reservoir. And I've already been out, cutting and splitting and piling, a month earlier than otherwise.

I am really impressed with Norway's ability to produce longform video that I find extremely compelling. Remember the 9 hour train video from a few years back?

This stuff appeals to me with a fervency and longing that surprises me, and makes me wonder if even 6 generations deep into American muttitude my Norwegianness shapes my tendencies and tastes. At any rate, I would love to watch the firewood video ("but occasionally her hands could be seen putting logs in the fireplace, or cooking sausages and marshmallows on sticks." OMG!), and I would also love to read that book.

The layer on top is always the layer you are about to use. It doesn't help you much if they wood in the middle of the pile is nice and shielded by the top layer and the wood you're trying to burn is soaking wet.

What they're talking about up there in Norway is in fact not the "use" pile but the "dry" pile: the one you create after you've cut and split your next season's wood.
"Dry" piles are assembled in these parts from around this time and - depending on the climate - until the end of April. You pile up the wood in airy rows, space between, in sexy conical piles, or whatever else shape that actually allows for some real air drying, and you have to stack as loosely as possible without causing collapse. Air drying only happens if you don't seal the stacks off too tightly, so no permanent tarp - perhaps a bit of corrugated roofing on top, but nothing more.
Then you can stack away everything in July, in a protected shed or similar, and it's ready for use. At that point, it is more efficient to stack the wood as tightly as possible, and the orientation of the bark doesn't matter a bit, since the wood's dry. Permanent protection is the most important.

You never use wood from a pile that's still drying out there, unless you're out of stock (been there).

You’re in a forest walking along in the rain when all of the sudden you look over, and you see a piece of firewood. You reach down, you flip the firewood over on its bark. The firewood lays on its bark, its wood beaten by the cold rain, doing nothing to try to turn itself over, but it can’t, not without your help. But you’re not helping. Why is that?

You’re watching television. Suddenly you realize there’s a moose in the room.

I stacked my wood with the bark facing in all sorts of crazy directions, for I was a maverick.

Well, that, and our wood shed had a roof.

Early on, we only ever had the woodshed full, but by the time I was a teenager, we mostly kept two years of wood on hand -- one for aging, one for burning. The aging wood was stacked behind the woodshed, on a bunch of cut end blocks, usually but not always split. We would bring in a winter's worth of wood over the course of about 2 weekends in early summer, and dump all the logs, cut to length but not split beside the woodshed.

We'd move the now aged wood into the woodshed and pack it willy-nilly and helter-skelter (in terms of bark -- the actual stacks were *very* neat and tidy for stability, especially as we would eventually stand on the lower stacks in order to stack the upper stacks) because the woodshed had a roof on it. That was usually my main task. Then my brother would split the new wood using a log splitter and we'd stack it behind the woodshed to age, covered in tarps.

I've always felt we could have saved ourselves an epic crapload of moving wood from one spot to the other if we had simply built a roof over the aging wood, too, and switched back and forth each year, which one was aging and which was burning. But then, since my brother and I had to do all that wood moving, I suppose my Dad didn't much care.

I am feeling almost nostalgic about bringing in wood right now, sitting in my comfy chair in my centrally heated condo, but I believe that sense of nostalgia wouldn't hold up to actually having to do any of those things we did. I hated it then, and I'd hate it more now.

That said, ya'll seriously stack your just-split wood that way ? And it dries in a year ?

I chimney stack all my wood. Two pieces one way, 2 pieces perpendicular to the first for the next level. Best way to get airflow all around, prevent rot, etc. I don't cover it until it gets moved into the dry/ready-to-burn pile in my halfassed wood shed.

Not really, but depends on the stove. In addition to improving combustion efficiency, there are additional technologies that can be used to decrease the particulate emissions. The paper "Ultra Low Emissions, European-Style Wood Combustion technology" provides some comparisons, but could be organized better. Pages 9, 10, 17 and 18 are relevant. There are other wood combustion strategies, such as rocket stoves, that also reduce emissions. It's kind of hard to quantify, though, as things such as fuel quality, wood placement, and proper flue maintenance can effect things quite a bit.

On top of this, complaining about the health effects of wood fires, while certainly relevant, is a total buzzkill. Give me a world where I can enjoy a nice fire with some friends and I will happily live in it.

If you really wanted your wood to dry as fast as possible, wouldn't you stack it as vertically as possible so that the moisture would flow out along the natural phloem and xylem channels under the influence of gravity (hence the conical stack, perhaps)?

And wouldn't you want it cut with as sharp a saw as possible to avoid mashing shut the water channels on the ends?

There is nothing more comfortable than the heat from a woodstove, even when the only way to regulate the temperature is to open windows. I miss that place.

We cover our 20 woodpiles with tarps, sheet metal, and plastic, so the bark direction doesn't matter.

wilful, People do build top-down fires, which appear strange to most of us, but are quite efficient and (so I'm told) reliable. The wood itself is not burning, but rather giving off gases that undergo combustion when they're sufficiently heated. When the combustion area is on top of the wood it's more likely for those gases to combust rather than escape to the atmosphere or condense in the chimney. I still haven't been able to bring myself to try it, yet, though...

We did Loggers Sports as the main focus of one of our summer festivals in my tiny town -- pancake breakfast, followed by axe-throwing, nail driving, cross-cut sawing and probably a couple of other things, followed by a potluck supper and dance -- but there are towns with bigger competitions and an official association that runs championships and whatnot.

wilful - You won't believe how good it is until you try it. It goes against 'everything you know about building fires', but it really is the most effective way - producing less smoke overall, and burning longer and more efficiently than burning from the bottom up.

Look up 'top down fires', and you'll find plenty of info - and try it!

If you take top-down fire building to the extreme, you end up with a Top-Lit-UpDraft gasifier, which runs on woodchip/pellets, burns only the "smoke", and leaves behind charcoal which can be buried in your garden as biochar (actual, working carbon storage unlike this).
