Why You Should Burn Kiln Dried Logs — Not Seasoned Logs

When it comes to heating your home with wood, not all logs are created equal.

At Woodstock UK, we’re often asked:

“What’s the difference between kiln dried and seasoned logs?”

“Does it really matter which one I burn?”

The short answer? Yes — it matters a lot. Burning kiln dried logs gives you more heat, less smoke, a cleaner stove, and better value for money. Here’s why.

What Are Kiln Dried Logs?

Kiln dried logs are dried in a purpose-built kiln, where temperature, airflow, and humidity are carefully controlled. This ensures that moisture is removed quickly and consistently, producing logs with a moisture content below 20% — the legal standard for Ready to Burn firewood in the UK.

At Woodstock UK, our kiln drying process guarantees:

✅ Consistently low moisture content

✅ Clean, pest-free logs

✅ Ready to Burn certification

✅ Maximum heat output with minimal waste

Burning kiln dried logs means less smoke, more heat, and a happier home.

What Are Seasoned Logs?

Seasoned logs are air-dried outdoors over time. In theory, this can work, but only if done properly, usually taking 18–24 months in the right conditions.

In reality, many “seasoned” logs you see on the market are:

Cut in spring or summer

Stored outdoors without proper airflow

Sold the following winter

Still well above 20% moisture content

These logs may look cheap, but they often burn poorly, smoke excessively, and can even damage your stove.

Kiln Dried vs Seasoned Logs — Key Differences

🔥 Heat Output

Kiln dried logs burn hotter because energy isn’t wasted evaporating water. Poorly seasoned logs can lose up to half their heat output.

💨 Smoke & Emissions

Wet logs produce more smoke and harmful particulates, affecting air quality and putting you at risk of breaking UK clean air regulations.

🧼 Stove & Chimney Health

Damp logs cause tar and creosote build-up, increasing the risk of chimney fires and expensive maintenance.

💷 Value for Money

Kiln dried logs may cost more upfront, but you’ll use fewer logs to get the same heat, making them a better investment in the long run.

Ready to Burn Certification Matters

In the UK, any firewood sold in volumes under 2m³ must be Ready to Burn certified, confirming moisture below 20%.

Many so-called seasoned logs:

Are not tested

Are not certified

Are sold illegally without the customer realising

Buying certified kiln dried logs gives you peace of mind safe, legal, and efficient firewood every time.
