Choosing the right firewood isn’t just about keeping warm – it’s about efficiency, cost, and the quality of your fires. Two top contenders are kiln dried and seasoned firewood, but which one truly delivers the best burn?
In this post, we’ll explore what sets these two types apart, from drying processes to performance, and help you determine the perfect option for your setup.
Stick around to learn why Stewart Timber proudly champions kiln dried firewood as the ultimate choice for heat, value, and sustainability!
What is Kiln Dried Firewood?
Kiln dried firewood is specially treated wood that’s dried in a large oven (called a kiln) to reduce its moisture content to less than 20%.
This process creates firewood that burns hotter and more efficiently, with less smoke and residue, compared to wood with higher moisture levels.
The consistent quality and immediate usability make kiln dried firewood a superior choice for indoor and outdoor fires.

What is Seasoned Firewood?
Seasoned firewood is wood that has been naturally dried over time to reduce its moisture content
Unlike kiln drying, this process relies on air and sunlight, often taking months or even years to complete. While it can eventually reach a usable moisture level, the results are less consistent, with some pieces retaining more moisture than others.
This variability can lead to less efficient burning, more smoke, and greater residue buildup compared to kiln dried wood.
However, if you’re planning ahead for next season, seasoning your own firewood can be a cost-effective option – just ensure it’s properly stored to keep it dry.

Pros and Cons of Seasoned Firewood
Seasoned firewood is a traditional option for those who don’t need immediate use and are willing to wait for natural drying.
Pros
- Lower Cost: More affordable than kiln dried wood, making it a budget-friendly choice.
- DIY Availability: Ideal for those who prepare firewood in advance for future use.
Cons
- Higher Moisture Content: Can lead to inefficient burning and increased smoke.
- Inconsistent Quality: Drying depends on weather and storage conditions.
- Long Wait Time: Requires months or years to dry before it’s ready to burn.
Key Differences Between Kiln Dried and Seasoned Firewood
Kiln dried and seasoned firewood differ in several critical ways:
- Drying Process: Kiln dried wood is dried in a controlled environment using heat and humidity, while seasoned wood is air-dried naturally over months or years.
- Moisture Levels: Kiln dried wood has a moisture content below 20%, whereas seasoned wood can vary and often retains higher moisture.
- Burn Efficiency: Kiln dried wood burns hotter, longer, and cleaner with less smoke; seasoned wood tends to burn less efficiently.
- Storage Needs: Kiln dried wood is ready to burn immediately, while seasoned wood requires proper storage to maintain its dryness over time.
- Pest Control: Kiln drying eliminates pests and insects, while seasoned wood may harbor bugs.
