Burning firewood that keeps your flue cleaner

Seasoned Hardwood

Seasoned hardwood is the best choice if you want to keep your flue cleaner. Woods like oak, maple, and ash, when properly dried, have a lower moisture content, resulting in hotter fires and less creosote. Creosote is a tar-like substance that deposits in the flue and can become a fire hazard.

Make sure the wood has been seasoned for at least six months to a year. Proper storage is key, so keep your firewood stack covered and off the ground to encourage air circulation.

Avoid High-Sap Woods

Avoid burning high-sap woods like pine or fir, as they produce more smoke and creosote, which can clog your flue. These types of wood are best for kindling due to their fast-burning nature, but they shouldn't form the bulk of your firewood supply.

Sap-heavy woods contribute to residue buildup inside the chimney, which can increase the risk of a chimney fire. For the best performance and safety, stick to hardwoods.

Kiln-Dried Firewood

Kiln-dried firewood is another excellent option for cleaner burning. This wood has been dried in a controlled environment, usually reducing its moisture level to below 20%. It lights easily and burns more efficiently than regular seasoned wood.

While typically more expensive, kiln-dried firewood is a good investment for those seeking to minimize creosote accumulation. Using this wood can reduce the frequency of chimney cleaning needed, helping maintain a safer and more efficient fireplace.
