Kiln-dried logs are logs that have been dried in a kiln to reduce their moisture content. To be legally sold in England, kiln-dried logs must be Ready to Burn certified with an overall average moisture content below 20%. To be dried effectively, Ready to Burn logs are placed in a kiln between 60 and 70°C. This process typically takes between a few days and a week, depending on the kiln and the type of wood being dried.

The main difference between kiln-dried and seasoned logs is the drying process. Kiln-dried logs are artificially dried in a hot kiln to reduce their moisture content. However, seasoned logs are dried naturally in the open air which can take several years. 

Kiln-dried logs offer superior burn efficiency compared to seasoned logs. These logs are ready to burn immediately and burn hotter and more cleanly. The kiln-drying process means the logs are dried evenly so the burn rate doesn’t slow down when the fire reaches a wet spot, which can be a problem with seasoned logs. This makes them a popular fuel for wood burners.

However, seasoned logs are typically cheaper than kiln-dried logs, but this comes at the expense of poorer burn quality.

Although it’s best to store kiln-dried logs indoors in a dry, low-humidity environment, they can also be stored outside in a log store or garage. However, you’ll need to ensure that your logs have sufficient airflow. You should:

• Avoid covering them completely.
• Keep them off the ground.
• Avoid stacking them against a wall.
• Position your log store in direct sunlight.
• Use a rain cover when the weather is bad.

How long kiln-dried logs take to burn will depend on their type, size and moisture content. For example, an average-sized oak log will burn for approximately 2-3 hours. Softer types of hardwood will likely have a slightly shorter burn time.

Kiln-dried logs can be much better for the environment than other types of fuel provided they are sourced and dried sustainably. At Westdale Logs, we are committed to sustainably producing high-quality kiln-dried firewood. We source a portion of our logs from local sustainable forests and all our wood is dried in our efficient and solar-powered kiln. Plus, our kiln-dried wood is only delivered to local homes and businesses helping to further reduce our carbon footprint.
