Lumber
Lumber, which is also known as timber, is wood that has been milled into beams and planks, a step in the production of wood. Aside from its use for structural purposes, lumber is also used for many other purposes. Lumber is more often made from softwood than hardwood, with softwood accounting for 80% of total lumber production.
Wood Log
Wood logs are the most popular kind of prepared wood. Wood logs are made out of trees like oak, beech, and …, which are known for their high-quality timber. Consequently, these logs burn exceptionally long, allowing you to wait a little longer before adding more wood to the boiler.
