Burning firewood that keeps your flue cleaner

Hardwoods vs. Softwoods

Hardwoods like oak, maple, and ash burn slower and hotter than softwoods, making them ideal for cleaner and more efficient fires. They produce less creosote, a byproduct of combustion that can accumulate in your chimney flue and increase the risk of chimney fires.

Softwoods, such as pine, tend to burn quickly and produce more creosote. If used, they should be fully seasoned and mixed with hardwoods to minimize residue in the flue.

Seasoning Your Firewood

Properly seasoned firewood is essential for a clean burn. Firewood should be split and stacked in a dry area for at least six months to a year before use. Well-seasoned wood will have a moisture content below 20%, reducing creosote buildup.

Signs of well-seasoned wood include darkened ends with visible cracks and a hollow sound when two pieces are banged together. Using seasoned wood ensures a cleaner chimney and less smoke output.

Choosing and Storing Wood

When selecting firewood, aim for hardwoods that are dry and seasoned. Oak, hickory, and apple wood are good choices for a hot, efficient fire. Proper storage is crucial—keep your woodpile off the ground and covered to protect it from moisture.

Store wood in a sunny, well-ventilated area to allow further drying. Avoid using painted or treated wood, as burning these materials can release harmful toxins.
