Best Firewood to Burn

1. Osage Orange (30M BTU/cord) — The undisputed king of firewood. Nothing else even comes close to 30 million BTU per cord. I remember the first time I loaded a stove with dry osage — I actually had to crack the door because it was putting out so much heat. Burns incredibly hot, holds coals forever, and a single load can carry you through the coldest night. The downside? It’s tough to split and throws sparks like crazy, so it’s a stove-only wood. But man, if you can get it, stockpile every last piece.

2. Shagbark Hickory (27.7M BTU/cord) — Honestly might be my personal favorite. The smell alone is worth it — there’s a reason people smoke meat with hickory. At nearly 28M BTU it puts out serious heat, holds coals beautifully overnight, and splits reasonably well for how dense it is. I’ve had hickory coal beds still glowing 10 hours after the last load. If someone told me I could only burn one species for the rest of my life, hickory would be a real contender.

3. White Oak (25.7M BTU/cord) — The reliable workhorse. Ask any old-timer what the best firewood is and nine times out of ten they’ll say white oak. They’re not wrong. It’s widely available across the eastern U.S., burns hot and steady, produces excellent coals, and you can usually find it at a reasonable price. The only knock is seasoning time — you’re looking at 24+ months for white oak to really be ready. But once it’s dry? Pure gold in the stove.

4. Black Locust (27.9M BTU/cord) — The most underrated firewood in America, hands down. Almost 28M BTU puts it right up there with hickory, but nobody talks about it. Black locust burns forever, throws minimal sparks, and seasons faster than oak. I’ve loaded locust at 10 PM and still had a hot coal bed at 7 AM. Splitting can be a pain — the grain twists something fierce — but a hydraulic splitter handles it fine. If you see black locust for sale, grab it before someone else does.

5. Sugar Maple (24M BTU/cord) — Clean, pleasant, and dependable. Sugar maple is one of those woods that just does everything right without being flashy about it. Good heat, low smoke, splits easily, and burns with a nice subtle sweetness. It’s the firewood equivalent of a Toyota Camry — not the most exciting thing in the world, but it always gets the job done and never lets you down. I burn a ton of this stuff every winter.

6. White Ash (24.2M BTU/cord) — If there’s a wood that splits like a dream, it’s ash. Seriously, a sharp maul goes through dry ash like it’s nothing. And unlike a lot of hardwoods, ash seasons fast — 6 to 12 months and you’re good to go. That alone makes it incredibly practical. The heat output is solid at 24.2M BTU, it throws low sparks, and it burns clean. With the emerald ash borer wiping out ash trees across the country, there’s been a lot of dead-standing ash available lately. Sad for the trees, but the silver lining is a lot of already-dry firewood.

7. Red Oak (22M BTU/cord) — Red oak is everywhere, it’s affordable, and it’s solid. Not as hot as white oak but still a very respectable 22M BTU. It seasons a bit faster too. I’ve always got at least a few cords of red oak in my stacks because it’s just so easy to source. Mix it with something hotter like hickory or locust and you’ve got yourself a perfect woodshed. Red oak is the foundation of any good firewood operation — reliable, affordable, and always available.

8. Apple (25.8M BTU/cord) — Oh man, apple wood. If you’ve ever burned it you know exactly what I’m talking about. The smell is incredible — sweet, warm, almost like baking. At 25.8M BTU it actually puts out more heat than a lot of the “serious” hardwoods, which surprises people. Apple is dense, burns slow, and the coals are fantastic. The only reason it’s not higher on my list is availability. Unless you live near orchards, it’s hard to find in quantity. But when someone’s cutting down an old apple tree? Get there fast.

9. Black Cherry (20.4M BTU/cord) — Cherry is one of those species that makes burning wood actually enjoyable rather than just a chore. The aroma is great — not as intense as apple, but a pleasant fruity scent that fills the room. At 20.4M BTU it’s not going to be your primary heater in a brutal northern winter, but it’s perfect for shoulder season or mixed in with your oak and hickory. Easy to split, easy to find in most of the eastern U.S., and it seasons in about 12 months. I always keep a stack of cherry for those evenings when I want a nice fire, not just heat.

10. Yellow Birch (20.8M BTU/cord) — Birch is the go-to when you want a quick, hot fire without waiting around. It lights easier than most hardwoods, burns hot and bright, and the papery bark makes incredible natural kindling. Yellow birch at 20.8M BTU is the best of the birch family for heat. I love it for shoulder season, for starting fires that I’ll add heavier wood to, and honestly just for the look of the flame — birch fires are beautiful. Don’t stack it with bark on for too long though... the bark holds moisture and the wood underneath can rot if you’re not careful.

Alright, let’s talk about the stuff I wouldn’t bother with. Now “avoid” is a strong word — if it’s free and already split, sure, burn it. But if you’re paying money or spending your Saturday processing wood, these species are not worth your time as primary heating fuel.

Willow — I burned willow exactly one winter and never again. It’s got terrible BTU, burns fast, and you’ll be feeding the stove every couple hours. The stuff is basically water held together with wood fibers. Takes forever to season because of the high moisture content, and even when it’s dry it’s just... meh. Unless you’ve got nothing else, don’t bother.

Cottonwood — Same story, different tree. Low heat, burns fast, and it has this funky smell that’s hard to describe but easy to dislike. I had a buddy drop off a trailer load of cottonwood rounds once — “free wood!” he said. Yeah, I figured out pretty quick why it was free. By mid-January I was mixing it 50/50 with oak just to keep the house above 60 degrees. Never again.

Softwoods (Pine, Spruce, Fir) — Now before the Pacific Northwest folks come after me — I know. In some regions softwood is what you’ve got, and that’s fine. Pine and fir can heat a house. But they burn fast, produce way more creosote than hardwoods, and you’ll go through twice as many cords per season. If you have access to hardwoods, use the softwoods for kindling and shoulder-season fires. That’s where they shine. Check the BTU chart to see just how big the gap is between pine and oak — it’ll make your jaw drop.

None of these rankings matter if you’re burning wet wood. I don’t care if it’s the best osage orange on the planet — if it’s at 35% moisture, it’s going to burn like garbage. A moisture meter takes the guesswork out of it entirely. Split a piece, stick the pins in the fresh face, and if it reads under 20% you’re good. I check every load before it goes in the stove. Takes five seconds and saves you from smoky, inefficient fires all winter long.
