Kiln Dried Vs Seasoned Logs – Is There A Difference?

When it comes to sourcing firewood for your fireplace or wood-burning stove, you may have come across the terms "kiln dried" and "seasoned" logs. But what exactly do these terms mean, and is there a difference between the two? In this blog post, we will explore the dissimilarities between kiln dried and seasoned logs, helping you make an informed decision when choosing the right type of firewood for your needs.

What Are Seasoned Logs?

Seasoned logs refer to firewood that has been naturally dried through exposure to air for an extended period. Typically, the logs are cut, split, and left to dry for a minimum of six months, but ideally for one to two years. During this time, the moisture content in the wood decreases naturally, making it suitable for burning.

Advantages of Seasoned Logs:

1. Reduced Moisture Content: The drying process of seasoned logs allows the wood to reach a low moisture content, providing a clean and efficient burn.

2. Improved Heat Output: With less moisture present, seasoned logs generate higher heat output, ensuring a warmer and cosier environment in your home.

3. Lower Creosote Build-up: Logs that have been seasoned correctly produce less creosote, a flammable substance that can accumulate in chimneys and pose a fire hazard. This makes seasoned logs a safer option for heating your space.

What are kiln dried logs?

Kiln dried logs, on the other hand, undergo a more controlled drying process. After being cut and split, the logs are placed in large chambers called kilns, where they are exposed to heated air circulation. This artificial drying method significantly reduces the moisture content in the wood, typically bringing it down to 10-15%.

Advantages of Kiln Dried Logs:

1. Low Moisture Content: Kiln dried logs have an exceptionally low moisture content, which makes them ignite more quickly and produce an intense, consistent heat. They are an excellent choice for those who require immediate and efficient heat.

2. Minimal Creosote Build-up: Similar to seasoned logs, kiln dried logs also generate less creosote, minimizing the risk of chimney fires and reducing the need for frequent chimney cleaning.

3. Pest and Mold Control: The high temperatures in the kiln eliminate any pests or mould that may be present in the wood, ensuring a clean and pest-free burning experience.

4. Quality: The kiln drying process means that every log will be dried thoroughly with consistent results. 

Is there a difference?

In terms of their suitability for burning, both seasoned (only if properly done) and kiln dried logs offer excellent performance. However, the key distinction lies in the quality. The kiln drying process is very thorough and ensures optimal moisture content all the time. If logs are air dried, they could take varying time to dry, potentially leading to you burning wet wood.

Whether you opt for seasoned logs or kiln dried logs, both options provide an efficient and eco-friendly source of heat. Ultimately, the choice between the two depends on your specific requirements, availability, and personal preference.
