Understanding Firewood BTU Ratings

BTU stands for British Thermal Unit, the standard measure of heat energy. When applied to firewood, BTU per cord tells you exactly how much warmth a neatly stacked 4×4×8-foot pile of seasoned wood can deliver to your home. It is the single most important number for comparing species, because it directly determines how many cords you will burn through in a season.

Not sure how many BTU your home actually needs? Our BTU calculator estimates your annual heating requirement in seconds. Enter your home size, insulation quality, and climate zone to get a personalized BTU number, then come back to this chart to find the species that match.

Dense hardwoods dominate the top of the chart. Oak species typically produce 22–26 million BTU per cord, Hickory varieties reach 24–25 million, and Osage Orange leads them all at roughly 30 million BTU. On the other end, softwoods like Pine and Spruce fall in the 15–17 million range. That difference is enormous in practice: a single cord of Osage Orange generates about the same heat as two full cords of Basswood.

Choosing the right species goes beyond raw BTU, however. Higher-density woods take longer to season. Oak needs 24 to 36 months of drying time compared to 6 months for Pine. Split difficulty, smoke output, and coal quality all factor into the real-world experience of heating with wood. The chart above lets you sort and filter on every one of these attributes so you can find the species that best matches your setup.

Once you know which species you want to burn, use our heating calculator to find out exactly how many cords your home needs for the winter. And if you are planning ahead, our seasoning guide will help you time your wood splitting so everything is dry and ready to burn when the cold arrives.

Frequently Asked Questions

What does BTU mean for firewood?
BTU (British Thermal Unit) measures heat energy. For firewood, BTU per cord tells you how much heat a stack of wood can produce. One BTU is the energy needed to raise one pound of water by one degree Fahrenheit.
What firewood has the highest BTU?
Osage Orange leads at roughly 30 million BTU per cord, followed by Gambel Oak (28M), Hickory varieties (24–25M), and White Oak (24.2M). These dense hardwoods produce the most heat per cord.
Is higher BTU always better?
Not necessarily. Higher-BTU woods like Oak take longer to season (12–24 months) and can be harder to split. For quick fires or shoulder-season use, fast-drying softwoods like Pine work well despite lower BTU.
How much heat does a cord of oak produce?
Red Oak produces about 22.1 million BTU per cord, while White Oak produces about 24.2 million BTU per cord. Both are excellent choices for primary home heating.
Does green wood have lower BTU than seasoned wood?
Green wood has similar potential BTU, but much of that energy goes toward evaporating moisture instead of producing heat. Properly seasoned wood (below 20% moisture) delivers its full BTU value as usable heat.
How do I calculate how many BTU I need?
Use our free BTU calculator to estimate your home’s annual BTU requirement based on square footage, insulation, climate zone, and stove type. Once you know your total BTU need, this chart helps you pick the best species to meet it.
