How to Choose the Right Firewood for Your Fireplace or Wood Stove

Quick Answer: Choose firewood by matching it to the appliance, not just the species. Every appliance wants dry wood, meaning moisture under about 20 percent by EPA guidance. Beyond that, an open fireplace forgives a mix of quick lighting wood and dense hardwood and looks best with shorter, slightly larger splits. A wood stove or insert rewards dense, evenly split hardwood sized to the firebox, because the stove is built to hold a long, steady burn. Test moisture with a meter, pick species for the job you want the fire to do, and size the splits to the opening you are feeding.

It is a bitter January evening in the Lakes Region, the kind where the thermometer outside the kitchen window has quit pretending to climb. You carry an armload in from the stack, kneel at the hearth, and the fire does one of two things. Either it catches quickly, settles into bright rolling flames, and warms the room for hours, or it hisses, smokes, and sulks while the glass on the stove door turns the color of weak tea. Nothing about your chimney changed between those two evenings. The wood did, and so did how well that wood matched the appliance you were feeding.



We cut, split, and deliver firewood around Middleton and the surrounding towns, and we hear the same question every fall. People ask which wood is best, as if one answer fit every hearth. It does not. A wide open masonry fireplace, a freestanding wood stove, and a fireplace insert all burn wood in different ways, and the best choice for one can be a poor choice for another. This guide walks through how to match the wood to the appliance, so you can stack the right fuel and get the fire you were hoping for.

Start With What Your Appliance Actually Does

Before you think about species, think about how your hearth handles fire. The three common setups in New Hampshire homes behave very differently.

Open Fireplace

An open masonry or prefabricated fireplace is mostly about atmosphere. The fire burns in the open, air rushes in from the room, and a good share of the heat goes straight up the chimney. You get light, crackle, and radiant warmth close to the hearth, but very little whole room heating. Because the fire is visible and the draft is strong, it tolerates a wider range of wood sizes and types.

Wood Stove

A stove is a controlled firebox. Air comes in through a damper or vents that you set, the door stays shut, and the steel or cast iron body radiates heat into the room long after the flames settle. Stoves are designed to burn hot and steady, and they reward wood that feeds that kind of burn: dense, dry, and consistently sized.

Fireplace Insert

An insert is a stove slid into a fireplace opening, usually with a blower and a flue liner. It behaves like a stove, sometimes a very efficient one, and it is picky in the same ways. Many inserts have a small firebox, so split size matters even more than it does in a freestanding unit.



If you are not sure which one you have, look at the manual or the label on the back or side of the unit. Manufacturers often state the maximum log length and the type of fuel they expect. That single line can save you a lot of guessing.

The First Rule for Every Appliance: Dry Wood

Species gets most of the attention, but moisture decides how any wood will behave. A freshly cut log holds a great deal of water, and the fire has to boil that water off before the wood itself can burn well. That wastes heat, slows the fire, and leaves more smoke and residue behind in your flue.

EPA guidance suggests burning wood with moisture content under about 20 percent, and recommends testing it with a moisture meter. University extension guidance for stoves points to a range of roughly 20 to 30 percent for air dried wood, with kiln dried wood sitting below 20 percent. The exact number depends on the wood and the weather it lived through, which is why a meter beats guessing.

You can also read the wood without a meter. Seasoned pieces are usually darker on the ends, lighter in the hand than a green log of the same size, and often show cracks radiating from the center. Knock two splits together. Dry wood gives a sharp, hollow sound, while wet wood gives a dull thud.

Why moisture matters more in a stove. An open fireplace burns hot enough at the front of the fire that slightly damp wood will often still light, even if it smokes. A stove or insert is different. You usually turn the air down to stretch the burn, and with damp wood that low air setting cools the firebox and produces smoke and sticky deposits in the flue. Wet wood and a closed down stove is the pairing most likely to leave a dark glass door and a dirty chimney.

Match the Species to the Job

Once the wood is dry, species is your second lever. We keep this part short here, because it is easy to overthink. Hardwoods such as ash, beech, maple, birch, and cherry are all good burners. They differ mainly in density, which controls how long a load lasts and how it behaves as it burns.

Dense hardwoods like beech and sugar maple pack a lot of energy into each split and burn long. They are the workhorses for a stove, where you want a load that holds coals and keeps the room warm through the night. Ash sits close behind, splits easily, and dries faster than most, which makes it a friendly choice for someone who wants good heat without a lot of fuss.

Lighter hardwoods like birch and cherry catch quickly and burn a bit faster. Birch lights readily and gives cheerful flames, and cherry adds a mild, pleasant aroma. In a stove, they work best mixed in with denser wood, or used to get a fire going on a cold start. In an open fireplace, they are often exactly what you want, since quick flames and pleasant smell are the point of the fire.



Softwoods such as pine, spruce, and fir are a different story. They light easily and burn fast, and many chimney professionals advise using them sparingly because they tend to leave more residue in the flue than dense hardwoods. General guidance puts hardwoods like oak and hickory at roughly 24 million BTU per cord or more, and softwoods like pine and cedar below roughly 17 million. A little softwood kindling to start a fire is fine. A whole winter of it in a stove is hard on the chimney and hard on your patience.

Choosing for an Open Fireplace

For an open fireplace, think about the evening you want. Most people are after a fire that lights easily, looks good, and gives off pleasant warmth and a bit of crackle.

A mix works well. Start with a few splits of birch or well dried softwood kindling to get flames going, then build with ash or maple so the fire settles into a steady, lasting burn. Cherry on top of a fire adds a sweet scent that fills the room.

Go a bit larger on the splits than you would in a stove. Open fires are fed by room air, and medium to large splits, rather than a pile of small sticks, burn calmly and last longer. Keep the logs a few inches shorter than the width of the hearth, so they sit squarely on the grate and do not roll forward.



Because so much heat rises up the flue, an open fireplace is a poor choice for damp wood. It may seem to burn fine, but the smoke and moisture condense in the cool upper chimney and leave deposits behind. Dry wood keeps the flames cleaner and the chimney in better shape.

Choosing for a Wood Stove or Insert

A stove is where wood choice pays off most. You are heating a room or a whole floor, and you want long, even burns with as few reloads as possible.

Reach for dense hardwood. Beech, sugar maple, and ash are the natural fits. A full load of dense hardwood settles into a bed of glowing coals that keeps throwing heat long after the flames calm down. That is what makes a stove work through a New Hampshire winter night.

Mix in a lighter wood for startup and for mild days. On a cold start, a few splits of birch or well dried kindling bring the firebox up to temperature fast. On shoulder season evenings, when you want some warmth but not a roaring stove, lighter hardwoods like birch and cherry give you a short, pleasant burn without overheating the room.

Size splits to the firebox. Many stoves and inserts have a stated maximum log length, and most burn best when the wood is a little shorter than that, so the load can sit with air space around it. Splits that are too long get jammed against the door or baffle. Splits that are too short stack up loosely and burn fast.

Keep the pieces fairly consistent. A load of pieces in similar sizes burns predictably. A mix of massive rounds and thin sticks burns unevenly, with the small pieces gone quickly and the large ones smoldering. Medium splits, often somewhere in the range of 3 to 6 inches across, are a common sweet spot for many stoves, though your manual should have the last word.

Split Size and Shape Change How Wood Burns

Split size is easy to ignore, but it changes how a fire behaves as much as species does. The same dry log can burn very differently depending on how it is cut.

Smaller splits have more exposed surface compared to their weight. They catch quickly, burn hot, and burn out fast. Larger splits ignite more slowly but burn longer. Good fire building uses both: small splits to establish the fire, and larger pieces to sustain it.

For an open fireplace, a few small splits as a base and medium to large pieces above them give you an easy start and a lasting burn. For a stove, start with small splits until the firebox is hot, then load medium splits for the long burn. Shape matters too. Splits with a flat side sit more stably on the grate or the coal bed, while very round or knotty pieces tend to roll and leave gaps.



If you have your own trees, mobile firewood processing can turn logs into evenly sized splits at your property, ready to stack and season.

What Burn Behavior Tells You About Your Wood

Your fire talks to you. A few signs help you judge whether you chose well.

Hissing, sizzling, or steam at the ends. That is water boiling out of the wood. It means the wood is wetter than it should be, and it needs more time to season.

A fire that struggles to catch or keeps dying. Damp wood is the most common cause, though a closed damper or a cold chimney can play a part. Try a drier batch and open the air control more while the fire is starting.



Dark, sooty glass on a stove door. This often points to wet wood, or to turning the air down too far, too early. Burn hotter for a few minutes after each reload, and check the moisture of your wood.

Steady flames, few sparks, and a bed of glowing coals. This is what you want. It means the wood is dry, the species suits the appliance, and the size is right.

Keep Your Chimney and Flue in Mind

Your choice of firewood affects your chimney, and a dirty flue is a safety concern. Burning wet wood, or burning too cool with the air turned way down, leaves creosote behind, a tarry residue that builds up on flue walls and can ignite. Dry, dense hardwood burned properly leaves less of it, but no firewood makes a chimney maintenance free.



Have a qualified chimney professional inspect and sweep your chimney or stovepipe on a regular schedule, and especially before the first fire of the season. If you notice a change in how your appliance draws, or see heavy deposits on the glass, treat it as a cue to check your wood and your chimney.
