Ohio law protects consumers by requiring firewood be sold by the cord or fraction of a cord, and bulk firewood may be purchased by weight in ton measurements if it is weighed on a certified scale. Measure to be sure it's a cord. A cord of wood is 128 cubic feet in volume, regardless of the shape it is stacked. Traditionally, a cord is a stack of wood eight feet long by four feet high and four feet wide. A properly stacked cord of wood should have pieces placed parallel to each other in a compact manner.
Seasoned hardwoods are best.
Unseasoned wood produces only two-thirds of the heat of seasoned wood. Hardwoods such as oak, hickory, ash, and beech are more dense and produce more heat than soft woods such as aspen or poplar. If a firewood dealer claims the wood is a specific type, the delivered load must contain at least 90 percent of that species of wood. Get a receipt. Firewood sellers must provide a sales invoice to buyers.
