Cordwood is a type of firewood that is cut into specific lengths and then stacked in a neat row. The most common length for cordwood is four feet, but it can also be cut into two-foot or six-foot lengths. Cordwood is typically used for either home heating or cooking, as it provides a consistent and long-lasting source of heat. When purchasing cord wood, it is important to make sure that the pieces are all the same length, as this will help to ensure a more efficient burn. In addition, cordwood should be seasoned for at least six months before being used, as this will help to prevent the formation of creosote deposits in your chimney.
