FAQs on Partially Seasoned Logs
What are partially seasoned logs?
Partially seasoned logs are firewood that has started the drying process but still retains a high moisture content, typically between 25-40%. Unlike kiln-dried or fully seasoned logs, they require additional drying time before they can be burned efficiently in wood burners, fireplaces, or stoves. If used too soon, they produce excessive smoke, create creosote buildup, and offer less heat output, making them an inefficient fuel choice.
Can I burn partially seasoned logs straight away?
No, burning partially seasoned logs immediately is not recommended. Due to their higher moisture content, they burn inefficiently, producing a lot of smoke and causing creosote buildup in chimneys and flue systems. This can increase the risk of chimney fires and reduce the efficiency of your wood burner or fireplace. For best results, logs should be fully seasoned or kiln dried before use.
How long do partially seasoned logs take to dry fully?
The drying time for partially seasoned logs depends on several factors, including the wood species, storage conditions, and climate. On average, they need anywhere from six months to a year to reach the ideal moisture level of 20% or less. Hardwood varieties like oak take longer to season compared to softwood options such as pine or spruce. Using a moisture meter can help ensure logs are adequately dried before burning.
How should I store partially seasoned logs for optimal drying?
To properly season partially dried firewood, store it in a dry, well-ventilated area with good airflow. Keep logs off the ground using a log store or a raised rack to prevent moisture absorption. Ideally, logs should be stacked loosely in a covered but open-sided storage space, such as a woodshed, allowing air circulation while protecting them from rain and snow.
Are partially seasoned logs cheaper than kiln-dried logs?
Yes, partially seasoned logs are generally more affordable than kiln-dried logs because they require additional drying before use. However, if you don’t have time or space to store and season them properly, kiln-dried logs may be a more convenient option. While kiln-dried firewood has a higher upfront cost, it provides immediate benefits such as higher heat output, cleaner burning, and reduced maintenance for chimneys and wood burners.
