Moisture Mapping Masterclass Understanding Wood Moisture Content for Firewood

Wood Moisture Content

Wood moisture content, the amount of water present in wood, is a crucial factor that affects its burning efficiency, durability, and safety. Understanding moisture levels is essential when selecting and maintaining firewood for optimal performance.

What is the Ideal Moisture Content for Firewood?

Seasoned firewood, with a moisture content between 15% and 25%, is recommended for efficient combustion. Wood below 20% moisture burns cleanly, producing less smoke and creosote, which can damage chimneys and reduce heating efficiency. Higher moisture content leads to poor combustion, wasted energy, and potential fire hazards due to excess smoke or steam.

• Below 15%: Seasoned to perfection, burns efficiently with minimal smoke and creosote build-up.
• 15% to 25%: Ideal moisture range, burns well with a balance of heat output and smoke production.
• 25% to 50%: Partially seasoned, burns inefficiently, produces smoke, and requires more energy to ignite and sustain.
• Above 50%: Wet wood, does not burn effectively, produces excessive smoke, and is not recommended for firewood.
