Beech wood is hard to beat compared to other hardwoods in terms of the exceptional heat it gives off. It is great for wood-burning stoves, and when it is seasoned properly, most people report a nutty aroma when burning this wood.
Even though beech wood is naturally dry, it still needs to be seasoned. Unfortunately for beech wood, it should be seasoned for at least a year, possibly two, for the absolute best burning results. Although, once it has been seasoned well, this wood dries out to an incredible 12% moisture content, compared to 20% most woods dry out to.
This extremely low moisture content allows this wood to burn much hotter, and the longer you season it, the less smoke it puts out. It is not as dense as oak or hickory, and so will not burn as long as those two kinds of wood.
However, with the extra heat it puts out, beech firewood is still an excellent choice of firewood. You probably will not mind throwing an extra log on the fire for added comfort.
