Why is firewood moisture content important?

Combustion efficiency: Wet firewood burns less efficiently than dry firewood. The water contained in the wood evaporates during combustion, requiring additional energy and reducing the flame temperature.

Calorific value: Wet firewood has a lower calorific value, meaning it produces less heat during combustion.
Soot formation: Burning wet firewood results in increased soot and resin formation, which settles on the walls of the chimney and can lead to clogging.
Chimney damage: Condensation formed during the combustion of wet firewood can contain aggressive substances that can damage the chimney.
What is the optimal firewood moisture content?
The optimal moisture content of firewood for burning is 15-20%. Firewood with this moisture content burns well, produces a lot of heat, and doesn't produce much soot.
