Each type of firewood has a unique moisture content when harvested, usually averaging around 50%. This moisture level is too high for efficient burning in stoves or fireplaces. The heat output of fresh or insufficiently dried wood can be reduced by up to half compared to dry wood, but there are many more issues. What problems can arise from burning wet firewood?

Damage to Your Fireplace and Surroundings

Burning wet firewood reduces heat output at the source due to water evaporation, but this is only the beginning of the problems. Wet firewood harms the entire heating system, the chimney, and even the surrounding air quality. Burning wet logs immediately starts creating issues, both short-term and long-term. This process produces more smoke and creosote. Excessive smoke can be a nuisance to neighbors and releases harmful pollutants and acidic compounds into the air, affecting a wider area. Creosote buildup can clog stoves and chimneys, and the metal parts of the heating system can suffer from corrosion and damage.

Even after the wet wood has burned, the problems continue. Expect more ash in the firebox and sooty black glass doors on your fireplace, requiring frequent cleaning due to the incomplete combustion of wet logs.

How to Check if Firewood is Dry or Wet

To burn efficiently, wood should have a moisture content of around 20% or less. How can you ensure your firewood meets this standard? One way is to buy kiln dried firewood, such as kiln dried logs for log burners or kiln dried hardwood logs, from a reputable supplier. Reliable firewood supplies, like EasyFlame can guarantee that you receive the best wood for log burners.

Another method is to test the wood yourself at home. Place a log in a plastic bag overnight. If there’s no condensation inside the bag by morning, the wood is dry enough for burning. Dry firewood also makes a clear, ringing sound when two logs are struck together. Additionally, dry wood will have visible cracks on the cut surface and won’t feel cold to the touch, unlike wood that still retains around 30% moisture.

For those in need of firewood for sale, consider purchasing kiln dried firewood. These logs are perfect for home fire log burners and ensure you get the best wood for wood burners. Investing in good wood for log burners not only ensures efficient heating but also protects your fireplace and home from the negative effects of burning wet wood.
