To As a result, many dealers sell fractions of cords, often called burn properly, wood should be between 15 and 20%, so a lot of “face cords”, “stove cords” or “furnace cords”, which are piles of water must evaporate out of each piece. wood 4 feet high and 8 feet long and as wide as the length of the individual pieces, usually between 12 and 20 inches. These are the factors that affect firewood drying time: The price of firewood sold in different fractions of cords can be compared by calculating the volume of wood sold as a unit and Species - very hard woods comparing its cost per full cord.

They also produce long- lasting fires and coal beds. Softer woods are less dense, burn faster and do not produce a long-lasting coal bed. Stacking Tips Coniferous trees like pine and spruce are less desirable as Stack the wood in separate firewood, and not just because of their low density.
