Choosing firewood for heating depends on many factors, such as the type of heating appliance, your budget, and the availability of different types of wood in your region. However, there are general guidelines to help you make the right choice.

Key Criteria for Choosing Firewood

Calorific Value: This is the amount of heat released when wood burns. The higher the calorific value, the less firewood you'll need for heating.
Wood Density: The density of wood affects the burn time and the amount of heat released. The denser the wood, the longer it burns and the more heat it releases.

Firewood Moisture Content: The moisture content of firewood is essential for combustion. Dry firewood burns well and produces a lot of heat, while damp firewood burns poorly, produces smoke, and can lead to soot in the chimney.

Ash Content: Ash content is the amount of ash remaining after wood combustion. The lower the ash content, the better. Price: Firewood prices c ... Read more »

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.
