Wood Moisture Content A Complete Guide for Firewood

Moisture content is a crucial factor to consider when using firewood. The ideal moisture content for firewood ranges between 15% to 20%. Firewood with a higher moisture content burns less efficiently, produces more smoke, and releases harmful emissions. Conversely, firewood with a lower moisture content is harder to ignite and burns too quickly.

Measuring Wood Moisture Content

Moisture Mapping is a non-destructive method to accurately measure the moisture content in wood. It involves using a moisture meter to measure the electrical resistance of wood. The higher the moisture content, the lower the resistance. Moisture mapping allows you to identify areas of high moisture content that require further drying or monitoring.

Ideal Moisture Content for Firewood

The ideal moisture content for firewood is between 15% to 20%. Firewood with a moisture content below 15% is considered dry and will burn efficiently, producing minimal smoke and emissions. Firewood with a moisture content above 20% is considered wet and will burn poorly, producing excessive smoke and releasing harmful pollutants.

Benefits of Dry Firewood:

  • Burns efficiently, providing more heat and less fuel consumption.
  • Produces less smoke, improving indoor and outdoor air quality.
  • Reduces the risk of creosote buildup in chimneys, preventing fire hazards.
  • Emits fewer harmful emissions, contributing to environmental protection.

To ensure optimal performance and safety, it is recommended to season firewood for a minimum of six months in a dry, well-ventilated area before burning.
