BTU stands for British Thermal Unit. 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.
Each specific type of wood will have its very own BTU rating. On top of that, the rating will change based on the wood’s moisture content.

Summary
At the end of the day, the BTU rating is very unique. It is never universal and will always vary from one wood to the next.
At the same time, the current condition of the wood will help determine the BTU.
If your wood is still wet, you can guarantee that the BTU rating is going to be much lower.
This is why it is pertinent to make sure that your wood has been dried completely before it is burned.
This is the best way to get the highest BTU rating and the most heat from your firewood.
