Burning firewood that keeps your flue cleaner

Importance of Dry and Seasoned Wood

Using dry, seasoned wood is crucial for keeping your chimney flue cleaner. Seasoned wood has been dried for at least six months, reducing moisture content significantly. This reduction limits the amount of creosote—an oily residue that can accumulate in chimneys—produced when burning.

Freshly cut, or 'green' wood contains a high moisture level, leading to inefficient burning and increased smoke production. This can result in greater creosote buildup, which is a leading cause of chimney fires.

Recommended Types of Firewood

Hardwoods like oak, maple, and birch are ideal choices for cleaner burning. They typically burn hotter and longer, providing more efficient combustion and less smoke. This efficiency reduces creosote production, helping to maintain a cleaner chimney.

Avoid softwoods such as pine, which contain high levels of resin. While these woods ignite quickly, they burn at a lower temperature and produce more creosote, increasing the need for frequent chimney cleaning.

Storing Firewood Properly

Proper firewood storage is essential for maintaining low moisture content. Stack wood off the ground with airflow around each piece to aid the seasoning process. Cover the top of the stack to protect it from rain and snow, but leave the sides open for air circulation.

Consider keeping your woodpile some distance from your house to prevent pests from migrating indoors. Regularly checking and rotating your stack helps ensure that the wood you use first is fully seasoned.
