Pin oak firewood
A cord of pin oak holds about 25.9 million Btu of heat, according to the University of Kentucky forestry table (at 20% moisture content). That ranks it #10 of 52 species on this site, 29% more than the 20 million Btu the U.S. Energy Information Administration uses for a generic cord of wood.

How much heat is in a cord of pin oak?
Only the University of Kentucky table lists pin oak, so its 25.9 million Btu is the one figure used here. It sits 5.1 million Btu above the median species (20.75), and it is #9 of the 38 hardwoods listed, whose average is 22.1 million Btu.
One cord of gambel oak, the highest in the table, holds as much heat as 1.19 cords of pin oak. In the other direction, a cord of pin oak replaces 1.88 cords of buckeye (horsechestnut), the lowest. In energy terms one cord equals the heat content of about 187 gallons of heating oil, using EIA's 138,500 Btu per gallon; the stove and the oil burner each lose some of that before it reaches the room.
Cords of pin oak for a winter
For the example house used across this site (2,000 sq ft, built in the 1970s, wood as the only heat, a 74% efficient stove), a normal winter takes:
| State | Degree days | Pin oak | Generic cord (20 M Btu) |
|---|---|---|---|
| North Dakota (coldest) | 9,184 | 5.3 cords | 6.9 cords |
| Oregon (median) | 5,269 | 3.1 cords | 3.9 cords |
| Florida (mildest) | 646 | 0.4 cords | 0.5 cords |
Because pin oak beats the generic cord, the stack is 23% smaller than the same winter on average wood. Your own house will differ; the calculator takes your state, floor area, house age and price.
Weight, splitting and how it burns
- Weight: Kentucky lists 3,144 lb per cord (24.6 lb per cubic foot of stacked cord, about 1,572 lb for a half-cord pickup load).
- Splitting: rated fair by Kentucky.
- Water in the living tree: 83% moisture content (Kentucky), on the wet side, so allow the full drying time.
Whatever the species, the heat figures assume dry wood. Seasoned firewood is below 20% moisture; fresh-cut wood is 35 to 50% water by weight (CMHC), and burning it wastes heat boiling that water off. The seasoning guide and the moisture meter guide explain how to get there and check it.
What a cord of pin oak is worth
Maine's Governor's Energy Office surveyed dealers at $355 a cord on September 21, 2026 (seasoned wood, minimum 2-cord purchase, local delivery included). Paid for as pin oak, that is $13.71 per million Btu in the wood, or $18.52 per million Btu delivered by a 74% stove. Dense species like this give the most heat for the money when dealers charge one price per cord regardless of species. Only two states publish a dated cord price; see Maine and New Hampshire.
