Heat per cord
Buloke Australian is a hardwood. At 20% moisture, a full cord holds about 39.6 million BTU of heat (41.8 gigajoules). Wetter wood gives less, because part of the heat goes into boiling off the water.
That ranks buloke Australian 42nd of the 558 species in our tables, from the hottest down.
Weight and density
A full cord of seasoned buloke Australian (20% moisture) weighs about 6,440 lb (2,920 kg). Freshly cut, the same cord weighs about 7,720 lb (3,500 kg): the difference is water you don't want to burn.
Its specific gravity, a measure of density, is 1.09. Denser wood packs more heat into each cord.
Seasoning time
Split and stacked off the ground, buloke Australian needs at least 12 months to dry to about 20% moisture.
Wood dries faster once it is split and stacked with air around it. A moisture meter on a fresh split face tells you when it is ready.
How it burns
- Ash: low
- Coals: very high
- Burn time: very long
