Most people worry about wood that’s too wet, not too dry. Wood with a moisture content below 20% is generally considered ideal for burning. It lights easily, burns hotter, and produces less creosote. But can it actually be too dry? It’s rare, but there are a few scenarios where wood can get so dry that it changes your burning experience.
Overly Fast Burn
When firewood is extremely dry—think kiln-dried below 10% moisture—it might burn very quickly, sometimes too quickly for certain stoves or fireplaces. You might find yourself feeding logs more often because they catch fire fast and burn up almost as quickly. That’s not necessarily bad, but it can be less efficient if you’re after a long, steady heat.
Bark and Structural Integrity
If wood has been stored for a very long time or in extremely hot, dry conditions, the bark can loosen or fall off, and the logs might start to feel crumbly. While the wood still burns fine, the pieces can become dusty and messy to handle. It’s more of an inconvenience than a real hazard.
Heat Output and Glowing Coals
Super-dry wood tends to produce a short burst of flames rather than a slow, steady burn with glowing coals. This can reduce the long-lasting heat you get from denser or slightly moister logs. People who rely on coals overnight might prefer wood that holds a little more moisture—just enough to sustain a slow burn.
Mixing for Balance
If your stash is extremely dry, you can mix it with wood that’s slightly higher in moisture. This approach slows the burn a bit, helping maintain heat over a longer period. It’s a simple trick that avoids wasting ultra-dry wood in a fast, flare-up burn.
Final Thoughts
While it’s uncommon for firewood to be “too dry,” some folks do prefer logs with a little more moisture for a slower, more controlled burn. Ultimately, extremely dry wood still lights up and heats your space, but it may require more frequent tending. If you find your wood is burning through too fast, consider mixing it with slightly moister logs or adjusting how you load the stove.
