Burning firewood that keeps your flue cleaner
Choosing the right firewood can help maintain a cleaner flue and a more efficient fireplace.
Seasoned Firewood
Seasoned firewood is wood that has been cut and left to dry for at least six months. Burning seasoned wood reduces the amount of creosote that builds up in your chimney. Creosote is a highly flammable substance that forms when wood burns incompletely, and it can lead to chimney fires if not managed properly.
Look for firewood that has a moisture content of around 20% or less. You can use a moisture meter to check this. Properly seasoned wood will be lighter, have cracks in the end grain, and make a clear clunking noise when two pieces are knocked together.
Types of Wood to Use
Hardwoods like oak, maple, and birch burn hotter and longer than softwoods, reducing the frequency of chimney cleaning needed. These woods produce less smoke and creosote, making them a better choice for maintaining chimney health.
Avoid burning pine or other resinous softwoods unless they are very well-seasoned, as they can produce more creosote. Mixing small amounts of softwood with hardwoods can be acceptable if you’re careful to maintain your overall firewood quality.
Storage Tips
Proper storage is vital for keeping your firewood dry. Stack wood off the ground on a firewood rack, and cover it with a tarp during wet weather while leaving the sides exposed for airflow. This will help the wood stay dry and continue to season properly.
Position your stack in a location that gets good sunlight and airflow. Avoid storing wood directly against the house, as this can invite pests and moisture problems. Regularly rotate your wood pile to use the oldest, driest wood first.
