Moisture mapping involves monitoring and managing moisture content levels in various materials, including wood. When it comes to firewood, achieving the optimal moisture content is crucial for efficient combustion and heating performance. Wood with high moisture content burns slowly, producing less heat and making it more difficult to light. Conversely, wood with excessively low moisture content can burn too quickly, reducing its heating potential.
To achieve optimal heating results, firewood should have a moisture content between 15% and 20%. This range allows for efficient combustion without excessive smoke or creosote buildup. Firewood with moisture content above 20% is considered “green” or “wet” and will burn poorly, releasing more smoke and less heat. Firewood with moisture content below 15% is considered “dry” and will burn too quickly, providing insufficient heating benefit.
Below is a table summarizing the ideal moisture content for firewood, along with the corresponding combustion efficiency and heating performance:

| Moisture Content | Combustion Efficiency | Heating Performance |
|---|---|---|
| <15% | Low | Poor |
| 15-20% | High | Excellent |
| >20% | Low | Poor |

It is recommended to use a moisture meter to accurately determine the moisture content of firewood before burning it. Seasoning firewood for an appropriate period can help reduce moisture content to the optimal level. Well-seasoned firewood, with a moisture content within the recommended range, burns efficiently, producing consistent heat and minimizing smoke and creosote accumulation.
