Firewood Heating 101

My first winter heating with wood was a disaster. Bought a cord of who-knows-what from some guy on Craigslist, half of it was green, and my house smelled like a campfire for three months. My wife was not thrilled. But even through that mess, I could feel it — there was something about the heat from a wood stove that the forced-air furnace just couldn’t touch. Deeper, more even, and honestly... it just felt good sitting next to the fire on a cold night.

The real reason I switched? Money. Our propane bill was getting absurd — $400+ a month in January. Meanwhile, I’m staring at 10 acres of woods behind the house. Once I got a decent stove and learned what I was doing, our heating costs dropped by more than half. And that’s buying wood, not even cutting my own. If you’re curious about the actual numbers, check out our firewood cost calculator to compare species by price per million BTU.

Beyond cost, there’s the independence factor. When the power goes out in an ice storm — and it will — you’re still warm. Your neighbors are at the hotel. You’re making coffee on the stove top. That peace of mind is worth a lot.

Here’s the deal — hardwoods and softwoods both burn. They both make heat. But the difference matters more than you think, especially when you’re trying to keep a house warm through February.

Hardwoods (oak, hickory, maple, ash) are denser. They burn longer, throw more heat per piece, and leave better coals. A stove full of oak can hold heat for 8+ hours overnight. That’s the difference between waking up to a warm house and waking up to 52 degrees wondering why you thought this was a good idea. Check our BTU chart to see the actual heat output numbers.

Softwoods (pine, spruce, fir, cedar) light easy, season fast, and split like butter. They’re great for kindling, shoulder-season fires when you just need to take the chill off, and getting a fire started before loading on hardwood. But for primary heat? You’ll be reloading the stove every couple hours.

The smart move is keeping both on hand. Softwood to start, hardwood to sustain. For a deep dive on all the different species, browse our firewood types encyclopedia.

Let’s talk stoves, because this is where a lot of beginners either get it right or waste a ton of money. First rule: do NOT heat your house with an open fireplace and think you’re saving anything. An open fireplace is maybe 10 to 15% efficient. Most of your heat goes straight up the chimney, and it actually pulls warm air out of your house to feed the draft. You might be losing heat on net. Seriously.

An EPA-certified wood stove? That’s 70 to 80% efficient. Night and day difference. You’ll use a fraction of the wood and actually heat your space. The two main types are catalytic and non-catalytic. Catalytic stoves have a combustor that reburns smoke, squeezing out more heat and burning cleaner. They’re more efficient but the combustor needs replacing every few years. Non-catalytic stoves are simpler, cheaper to maintain, and still very efficient. For a first stove, non-cat is probably the way to go.

Size matters. A stove rated for 2,000 square feet in a 900 square foot cabin means you’ll be running it low all the time, which causes smoldering, incomplete combustion, and creosote. Get the right size for your space. And don’t cheap out on installation — a proper chimney and clearances are the difference between cozy and catastrophic.

If I could go back and hand myself a checklist before that first disastrous winter, this is what it would say:

1. Figure out how much you need. Don’t eyeball it. Run the numbers with a heating calculator and then buy a little extra. Running out in January is a lesson you only want to learn once.
2. Buy seasoned hardwood — or buy green a full year early. If it’s already September, you’re too late for green wood. Find someone selling properly dried hardwood and verify it with a moisture meter.
3. Get a moisture meter. Twenty-five bucks. Best investment in your firewood setup, bar none. You’ll use it every single time you question whether a batch is ready.
4. Stack it right. Off the ground, top covered, sides open for airflow. A sunny south-facing spot is ideal. Bad stacking = moldy wood = wasted money.
5. Clean your chimney before burning season. Every year. No exceptions. A chimney fire is not something you want to experience. Hire a sweep or do it yourself with a brush kit, but get it done before you light the first fire.
6. Start with easy-splitting species like ash. Ash splits beautifully, seasons relatively fast, and throws good heat. It’s the perfect beginner wood. Elm, on the other hand? That stringy nightmare will make you question every life choice that led you to firewood.
7. Keep a small softwood stack for kindling. Pine, spruce, cedar — they catch fast and get your fire rolling. Trying to light a cold stove with nothing but dense oak is an exercise in frustration.
8. Build up to overnight burns with dense hardwood. Once you’ve got the fire established with kindling and medium wood, load it up with oak or hickory before bed. Close the air down, and you’ll have coals in the morning to restart from. That’s the goal.
