Btu Lb Hardwood Softwood

185 will heat up to 5 182 sq feet including all buildings well insulated plus hot water burning a good seasoned hardwood like oak.

Btu lb hardwood softwood.

To get the most energy out of your firewood the wood should be seasoned. Less dense softwoods have less btu per cord than more dense hardwood but they also weigh less per cord. It is said that under ideal conditions one pound of wood 0 mc can produce 8600 btu s. Btu is nothing more than the amount of energy needs to head a single pound of water and increase the temperature by a single degree.

This might seem pretty basic but it can make a huge difference for people who are attempting to heat their home using firewood. One pound of dense hardwood will have about the same amount of energy as one pound of light softwood. A cord of the more dense wood will have more energy than a cord of less dense softwood. Species that contain a high amount of resin can produce as much as 9000 btu s pound.

Btu or british thermal unit is the amount of energy required to heat one pound of liquid water by one degree fahrenheit. Non resinous wood has around 8000 to 8500 btu per pound and resinous wood has around 8600 to 9700 btu per pound. All species of wood generate similar heat btu s on a per pound basis with a slightly higher amount for high resinous species of trees. As you can see from the chart below the famed red oak is not the highest on the list.

Seasoned firewood is described as having a 20 moisture content. The btu in a cord of firewood is usually close to the same per pound between species. Seasoning firewood takes time. The difference in energy content is in the woods density.
