Wood stoves are an excellent source of efficient and cozy heat. However, choosing the right type of wood and understanding its components is crucial for safe and efficient operation. One common question that arises is whether it’s advisable to burn bark in a wood stove. In this article, we’ll delve into this topic, providing a clear and concise answer.
Burning Bark in a Wood Stove: The Basics
Bark is the outer protective layer of a tree, and it’s often found on firewood. While it can be tempting to burn bark, there are some important factors to consider.
1. Bark Contains More Moisture: Bark typically has a higher moisture content compared to the inner wood of a tree. This excess moisture can lead to incomplete combustion and result in creosote buildup in your chimney.
2. Creosote Buildup: When moisture in the wood doesn’t vaporize completely during combustion, it produces creosote, a flammable, tar-like substance. Excessive creosote buildup in your chimney can lead to chimney fires, a significant safety hazard.
3. Inefficient Burning: Burning bark can result in less efficient burning because you might need to use more wood to achieve the same level of heat compared to using dry, seasoned firewood.
4. Increased Maintenance: Burning bark can lead to more frequent chimney cleaning and maintenance due to the higher creosote buildup.
So, Should You Burn Bark in a Wood Stove?
In general, it’s best to avoid burning bark as your primary source of fuel in a wood stove. Here are some recommendations:
1. Use Seasoned Wood: Always opt for well-seasoned firewood, which has a moisture content of about 20% or lower. Seasoned wood ensures efficient combustion and minimal creosote formation.
2. Mix with Hardwood: If you have wood with bark, consider using it in conjunction with hardwoods like oak, maple, or hickory. The hardwoods will provide a stable and efficient burn while the bark can be used sparingly to enhance the flame or fragrance.
3. Keep the Fire Hot: If you decide to use bark, ensure that your stove is operating at a high temperature. This helps to burn off some of the excess moisture and reduce creosote formation.
4. Regular Cleaning and Inspection: Regardless of the type of wood you use, ensure that your wood stove and chimney are cleaned and inspected regularly to prevent creosote buildup.
Conclusion
While you can burn bark in a wood stove, it’s not the most efficient or recommended practice due to its higher moisture content and potential for creosote buildup. To ensure the safe and efficient operation of your wood stove, it’s best to use well-seasoned firewood with lower moisture content. If you choose to burn bark, do so sparingly and in conjunction with seasoned hardwoods while maintaining proper stove maintenance and safety practices.
