Burning firewood that keeps your flue cleaner

Seasoned Firewood

Using seasoned firewood is essential for a cleaner flue. This type of wood has been dried for at least six months, reducing its moisture content to about 20%. Seasoned wood burns more efficiently and produces less smoke, thus limiting creosote buildup in your chimney.

Unseasoned or 'green' wood contains a higher moisture level, leading to inefficient burning and increased creosote production. It also produces more smoke, which can escape into your living space and lead to unpleasant odors and potential health hazards.

Hardwoods vs. Softwoods

Hardwoods like oak, maple, and hickory are preferable for burning as they produce a hotter, longer-lasting fire with less creosote. Their dense fibers create fewer sparks and emit less smoke compared to softwoods, making them ideal for maintaining a cleaner flue.

Softwoods, such as pine or fir, burn faster and produce more soot and creosote, which can lead to increased buildup inside your chimney. If softwoods are your only option, be diligent with chimney cleaning to prevent potential blockages or chimney fires.

Storing Firewood

Proper firewood storage is necessary to ensure it remains seasoned and ready for use. Stack wood off the ground in a dry, ventilated area, preferably covered with a tarp to shield it from rain or snow. This keeps the wood dry and ready for burning, minimizing creosote production.

Allow adequate airflow around the woodpile to speed up drying. Avoid stacking firewood directly against your home's siding, as this can attract pests like termites and increase the risk of moisture damage to the building.
