Wood-burning stoves are beloved for their ability to provide warmth and comfort during the cold months. However, the question of whether or not firewood should be covered is one that often arises among wood stove owners. To address this, we’ll dive into the technical details and provide a clear, concise answer for both technical and non-technical audiences.
Why Cover Firewood?
Properly seasoned firewood is essential for efficient wood burning. Seasoning involves allowing the wood to dry to a moisture content of around 20% or lower, which is ideal for combustion in wood stoves. Covering firewood serves several important purposes:
Protection from Moisture: Firewood exposed to rain or snow can absorb moisture, increasing its moisture content. Wet wood is difficult to burn efficiently and can lead to creosote buildup in your stove, a safety hazard.
Preventing Mold and Rot: Moisture not only affects burn efficiency but also encourages mold growth and wood rot. Covered wood stays drier, reducing the risk of fungal infestations.
Prolonged Lifespan: Covered firewood can last longer and maintain its quality. Dry wood is less susceptible to decay, ensuring you get the most value from your firewood investment.
Choosing the Right Firewood Cover
When covering your firewood, it’s important to select the right materials and techniques. Here’s what you need to consider:
Cover Design: Use a tarp or firewood rack with a weatherproof cover. A well-ventilated cover can protect the wood while allowing air circulation to aid in drying.
Elevate the Wood: Ensure that the wood isn’t directly on the ground. Using pallets or a firewood rack helps prevent moisture from seeping up into the wood from the ground.
Proper Ventilation: Avoid fully enclosing the wood, as this can trap moisture. Leave the sides open or ensure there is some space for air circulation.
When Not to Cover Firewood
There are situations where covering your firewood is not necessary:
Fully Seasoned Wood: If you have properly seasoned wood with low moisture content, and you plan to use it within a short period, covering may not be needed. However, it’s still a good practice to keep it off the ground to prevent contact with moisture.
Well-ventilated Storage: If you have a storage area that provides ample ventilation and protection from rain or snow, you may not need a separate cover.
Short-term Storage: For short-term storage of wood that will be used soon, covering may be unnecessary. Just ensure it stays dry until it’s burned.
In conclusion, the decision of whether or not firewood should be covered depends on various factors, including the state of your firewood, storage conditions, and your intended use. For long-term storage and to ensure the best performance from your wood-burning stove, it’s generally a good practice to cover your firewood. Properly seasoned, dry firewood is the key to efficient and safe wood stove operation.
