Firewood Burning Tips

How much wood is in a cord? The cord is the standard measure of volume used for stacked wood. The volume of one cord of wood is 128 cubic feet of stacked wood. Generally, a cord is laid out in stacks that measure 4 feet wide, 4 feet tall, and 8 feet long (4’ x 4’ x 8’) in total. Due to air space between the stacked wood, the volume of solid wood in a cord may be only 70 to 90 cubic feet.

What is a “rick” or “face cord” of wood? Usually, a cord is made up of a few stacks of wood. One stack of a cord is called a “rick” or a “face cord.” Generally, a rick is 4 feet tall by 8 feet long, and the width of a rick will depend on the length of the individual pieces of firewood. Because of this variability in width, a rick could be equal to ¼ of a cord, ½ a cord, or more.

What is heat value? Heat value refers to the amount of heat a wood produced when burned. Heat value varies based on the type of wood: A cord of wood with “high heat value” provides the heat equivalent to that produced by burning 200 to 250 gallons of heating oil. Other heat values are listed above.

Cutting wood: Freshly cut wood contains up to 50 percent moisture and must be seasoned (dried) to 20 to 25 percent moisture content before burning. Wood containing more than 25 percent moisture is wet, or green, and should never be burned in a fireplace or wood stove.

Splitting wood: Wet wood is easier to split than dry wood. Wood must be split into pieces and stacked out of the rain for at least six months to season properly.

Seasoning firewood: If steam bubbles and hisses out of the end grain as the firewood heats up on the fire, the wood is wet, or green, and needs to be seasoned longer before burning. Well-seasoned firewood generally has darkened ends with visible cracks or splits. It is relatively lightweight and makes a sharp, distinctive “clink” when two pieces strike each other.

Burning pine: Limit the amount of pine you burn. It’s a resinous softwood.

Buy local: Only buy firewood from local sources. Buying and moving firewood from elsewhere (especially from state to state) is not only frowned upon, it may also be illegal. Transporting firewood from one place to another increases the chance of spreading invasive pests and diseases.
