Choosing the best firewood for wood stove heating has a bigger effect on your winter than almost anything else. The right wood lights easily, burns hot and clean, and keeps your glass clear. The wrong wood smokes, hisses, and leaves you feeding the stove all night for half the heat.
We sell and service Vermont Castings and Quadra-Fire wood stoves, and the first question we ask when a customer says their stove “isn’t heating” is always about the wood. Here’s what we tell them.
What Is the Best Firewood for Wood Stove Heating?
The best firewood for a wood stove is dense hardwood, split and seasoned to below 20% moisture. Oak, sugar maple, hickory, ash, and birch are top choices. Dryness matters even more than species. A well-seasoned average wood outperforms a wet premium one every time.
Firewood Heat Value by Species

A full cord is a stack measuring 4 feet high, 4 feet deep, and 8 feet long, or 128 cubic feet. When you buy firewood, confirm whether the seller means a full cord or a smaller “face cord.”
Hardwood vs. Softwood
Hardwoods like oak, maple, and ash are denser, so they burn longer and produce more heat per load. They’re the backbone of a good winter woodpile.
Softwoods like pine and spruce light quickly and burn hot but fast. They’re useful for kindling, starting fires, and mild fall or spring days when you want a short, quick fire.
A common myth says softwood causes creosote. In reality, wet wood of any species is the main cause. Dry softwood burns cleanly in a modern stove.
Why Seasoning Matters Most
Freshly cut wood can be half water by weight. When you burn it, the fire spends energy boiling off that water instead of heating your home. The results:
• Less heat in the room
• More smoke and pollution
• Black, sooty glass
• Faster creosote buildup in the venting
TheEPA’s Burn Wise guidance says wood burns best at a moisture content below 20%. TheU.S. Department of Energy adds that complete combustion in certified stoves helps prevent the buildup of flammable creosote, and dry wood is what makes complete combustion possible.
How Long to Season Firewood
The EPA recommends seasoning softwood for at least 6 months and hardwood for at least 12 months. Dense woods like oak often benefit from even longer.
How to Tell if Firewood Is Dry
• Use a moisture meter. Split a piece and test the fresh inside face. Under 20% is ready.
• Look at the ends. Seasoned wood shows cracks and splits on the ends.
• Check the weight. Dry wood feels noticeably lighter than green wood.
• Knock two pieces together. Dry wood makes a hollow, sharp crack. Wet wood thuds.
• Check the bark. It often loosens or falls off as wood dries.
How to Store Firewood
Good storage keeps seasoned wood dry and helps green wood dry faster. TheEPA’s firewood storage guidance recommends:
1. Split wood before stacking to speed drying.
2. Raise the stack off the ground on a base or rails to limit moisture and pests.
3. Cover the top only. Leave the sides open so air can move through.
4. Slope the cover so water runs off.
5. Stack in a sunny, breezy spot away from the house.
Bring in only a day or two of wood at a time. Storing large amounts indoors can bring in insects.
Buying Firewood: What to Ask
If you buy firewood instead of cutting your own, a few questions help you get what you pay for:
• Is it a full cord or a face cord? Prices and volumes vary widely between the two.
• What species is it? Mixed hardwood is common. Ask what’s in the mix.
• When was it cut and split? Wood cut this season likely isn’t ready to burn yet.
• Has it been covered? Wood stored uncovered in the rain may test wetter than you expect.
When it arrives, test a few split pieces with a moisture meter before you stack it. If it’s above 20%, plan to burn it next season and buy dry wood for now. Buying ahead is the easiest way to always have the best firewood for wood stove use on hand.
What Never to Burn in a Wood Stove
The EPA warns against burning:
• Household trash, including cardboard, plastics, and foam
• Glossy or colored paper like magazines and wrapping paper
• Painted, stained, or pressure-treated wood
• Wet, rotted, or moldy wood
Also skip driftwood, which can contain salt, and unknown pallet wood, which may be chemically treated.
A Simple Seasonal Firewood Plan
The easiest way to always have dry wood is to work a year ahead. Here’s the rhythm many of our customers follow.
Late winter and spring: Buy or cut next winter’s wood. Split it right away and stack it in a sunny, breezy spot with the top covered. This gives hardwood the full year it needs to season.
Summer: Let the sun and wind do the work. Check the stack after heavy storms to make sure the cover is still in place.
Fall: Test a few pieces with a moisture meter before heating season. Move a week’s worth of seasoned wood closer to the house, under cover.
Winter: Burn this year’s dry wood while next year’s pile seasons. Bring in only a day or two of wood at a time.
Keeping two stacks, one ready to burn and one seasoning for next year, is the single best habit for clean, hot fires.
Getting the Most Heat From Your Firewood
• Mix sizes. Keep kindling, small splits, and larger splits on hand.
• Load for the job. Smaller, hotter fires for mild days. Full loads of hardwood for overnight burns.
• Build hot fires. A smoldering fire wastes wood. Start with plenty of kindling, keep the air open until the stove is fully hot, then close it down gradually.
• Keep your stove in shape. Worn gaskets and dirty venting reduce efficiency no matter how good your wood is.
When Your Stove Is the Problem
If you’re burning dry hardwood and still fighting smoke, low heat, or dirty glass, your stove may need service. Our factory-trained technicians clean and service wood stoves and venting and check gaskets and air controls. Learn more on ourservice page.
Older stoves without EPA certification burn far less efficiently than modern models. If yours is showing its age, browse ourwood stoves and inserts collection, read ourwood stoves and inserts guide, or compare fuels in ourgas vs. wood fireplace guide.
Keep working carbon monoxide alarms on every level of your home, as theU.S. Consumer Product Safety Commission recommends.

Frequently Asked Questions
What is the best firewood for a wood stove?
Dense, well-seasoned hardwoods like oak, sugar maple, hickory, ash, and birch are the best choices. Dryness matters even more than species.
How dry should firewood be for a wood stove?
Below 20% moisture content, according to EPA Burn Wise guidance. A moisture meter is the easiest way to check.
Can you burn pine in a wood stove?
Yes, if it’s dry. Seasoned pine lights fast and burns hot, which makes it great for kindling and mild days. Wet wood of any species causes creosote.
How long does firewood need to season?
The EPA recommends at least 6 months for softwood and 12 months for hardwood, stored off the ground with the top covered.
What should you never burn in a wood stove?
Trash, cardboard, glossy paper, painted or pressure-treated wood, wet or moldy wood, driftwood, and unknown pallet wood.
