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.

How to determine the moisture content of firewood?

Visually: Dry firewood is lighter in color, lighter in weight, and has cracks on the surface. Wet firewood, on the other hand, is darker in color, heavier, and may have mold or rot.

To the touch: Dry firewood feels warm and dry, while wet firewood feels cool and damp.
Using a moisture meter: There are special devices called moisture meters that allow you to accurately determine the moisture content of wood.

How to properly store firewood to keep it dry?

Storage location: Firewood should be stored in a dry, well-ventilated area, protected from rain and snow.
Stacking: Firewood should be stacked so that there is space between them for air circulation. Storage Time: To achieve optimal moisture content, firewood should be stored for 6-12 months.

What should I do if my firewood is damp?

Drying: Wet firewood should be dried before burning. To do this, lay it out in a dry, warm place for several days or weeks.
Using for Kindling: Wet firewood can be used to start a fire, but once the fire is established, it is better to add dry firewood.
Conclusion
The moisture content of firewood is an important factor affecting heating efficiency and safety. Proper storage and preparation of firewood will ensure maximum heat and enjoyment from your fireplace or stove.
