Best Firewood to Burn: Heat, Smoke and Price
The short answer is oak for heat, ash for convenience, and whatever is cheap and local for everything else. But "best" depends on whether you are heating a house or lighting a fire on a Saturday, and the differences are real enough to be worth knowing.
By species
| Wood | Heat per cord | Seasoning | Notes |
|---|---|---|---|
| Oak | ~27M BTU | 12–24 months | The benchmark. Long, steady burn. Slow to dry and worth the wait. |
| Hickory | ~28M BTU | 12–18 months | Highest heat of the common woods. Excellent, often pricey. |
| Maple | ~24M BTU | 12 months | Very good all-rounder, widely available. |
| Ash | ~24M BTU | 6–12 months | The practical choice. Splits easily, dries fast, burns clean. |
| Birch | ~20M BTU | 6–12 months | Lights beautifully, burns fast. Good mixed with something slower. |
| Cherry | ~20M BTU | 12 months | Pleasant scent, moderate heat. A treat rather than a staple. |
| Pine, fir, spruce | ~15–20M BTU | 6–12 months | Fast, hot, short. Fine in a stove when seasoned — see below. |
| Poplar, willow | ~14M BTU | 6–12 months | Low heat, burns away quickly. Shoulder-season wood. |
The pine question
You will be told softwood is dangerous because it causes creosote. That is mostly a misunderstanding worth clearing up.
Creosote comes from wet wood and cool, smouldering fires, not from resin. Properly seasoned pine burned in a hot stove is perfectly reasonable fuel. It lights easily, gets a fire going fast, and in much of the western US it is what is available and affordable.
What is true: pine burns faster, so you handle more wood for the same heat, and it throws more sparks — which matters in an open fireplace and not at all behind a stove door. Green pine is genuinely bad, but so is green oak. See seasoned vs green.
What to avoid entirely
- Treated, painted or stained timber. Burning it releases genuinely toxic compounds. Never, in any appliance.
- Plywood, MDF, chipboard. Adhesives and formaldehyde.
- Driftwood. Salt releases corrosive compounds that eat flue liners.
- Pallets, unless you can confirm they are heat-treated rather than chemically fumigated, and free of nails.
- Anything mouldy. It has already lost heat value to rot and the spores are unpleasant indoors.
Match the wood to the job
- Overnight burn in a stove — oak or hickory. Density is what makes a fire last.
- Getting a fire going — birch or softwood kindling, then load the hardwood.
- Open fireplace — hardwood, for fewer sparks and less smoke in the room.
- Pizza oven or cooking — dense hardwood, and nothing resinous.
- Shoulder season — the lighter woods. A full load of oak in October is more heat than you want.
Buy local before you buy the best species
Two reasons this beats chasing oak.
Cost. Firewood is heavy and cheap per pound, so haulage is a large share of the price. Wood from thirty miles away is usually better value than a better species from a hundred.
Pests. Moving firewood long distances spreads emerald ash borer, spotted lanternfly and others, and many states restrict it for exactly that reason. The standard guidance is to buy within about 50 miles of where you burn it.
