Can You Burn Ash Dieback Logs? The Complete Guide

Ash dieback—caused by Hymenoscyphus fraxineus (Chalara)—is affecting ash trees across the UK and Europe. As more affected trees are felled, many stove owners ask: Can you burn ash dieback logs? The short answer is yes, provided you select, dry and burn the wood correctly. This guide explains how to use ash dieback timber safely and efficiently, and why kiln dried logs are the gold standard for performance and peace of mind.

What Is Ash Dieback?

Ash dieback infects leaves, shoots and stems, gradually weakening the tree. While it’s devastating for living trees, once felled the wood itself is not “toxic.” With proper drying and handling, affected ash can still be turned into excellent firewood for wood burners, stoves and even open fireplaces.

So… Can You Burn Ash Dieback Logs?

Yes—under the right conditions. Lightly affected ash that’s been dried to a low moisture content behaves much like healthy ash. Heavily decayed sections, however, can be crumbly and hold moisture, reducing heat output.

• Benefits: Sustainable use of felled trees; naturally dense hardwood; strong, steady heat—especially when bought as hardwood kiln dried logs.
• Drawbacks: Advanced decay lowers density and makes ignition inconsistent. Choose solid pieces and ensure they’re truly ready to burn (≤20% moisture).

Why Kiln Drying Is a Game-Changer

Moisture is the biggest performance killer. High-moisture wood wastes heat energy evaporating water, smokes more, and can increase creosote. Kiln drying solves this by removing moisture quickly and uniformly, delivering reliable, efficient fuel.

Key Advantages of Kiln Drying

1. Cleaner fuel: The controlled heat environment helps neutralise residual fungal activity and pests—removing the “nastiness” and giving cleaner-to-handle fuel.
2. Consistent low moisture: Typically 15–20%, which means easier lighting and a hotter, cleaner burn. Pair with kindling and firelighters for effortless starts.
3. Uniform performance: Even dieback-affected pieces burn predictably when they’re truly dry—especially useful for modern wood burners and stoves.
4. Less storage fuss: Kiln-dried products are ready on delivery—ideal if you order kiln dried log crates or bulk bags.

Best Practices for Ash Dieback Firewood

Selecting Logs

• Pick solid, dense pieces; avoid hollow or crumbly sections.
• Brush off loose debris before storage; keep seasoned stacks off the ground.
• If buying, choose certified Ready to Burn logs to ensure low moisture.

Drying & Storage

• If not purchasing kiln-dried, season under cover with strong airflow. Aim for ≤20% moisture.
• Stack by size: small logs help light quickly; long burning logs keep heat steady.

Burning Technique

• Build a hot bed with kindling and stove-compatible firelighters.
• Maintain airflow for clean combustion; avoid prolonged smouldering.
• Sweep chimneys regularly—especially if you ever burn marginally seasoned wood.

Choosing the Right Product Format

Match your usage to the right pack size and delivery method:

• Log crates: best value per cubic metre; neatly stacked, low mess.
• Bulk bags: breathable, convenient for regular users.
• Bags of kiln dried logs: handy top-ups or smaller households.
• Nationwide log delivery: choose the slot that suits your access and storage.

Species Choices & Use-Cases

Ash remains a top performer, but mixing species can optimise results:

• Ash: reliable heat, steady flame—great all-rounder.
• Oak: very dense, superb for slow burning and overnight embers.
• Birch: easy lighting, lively flame—pair with oak or ash.

Special applications:

• Logs for pizza ovens: dry, dense hardwoods for fast heat-up and clean flavour.
• Fire pit logs: low-spark options for outdoor flames and ambience.

Kiln Dried vs Air-Dried at a Glance

FAQs

Can you burn ash dieback logs straight after felling? – No. Even ash needs drying. Buy kiln dried hardwood logs or season thoroughly before use.

Is kiln drying essential? – Not mandatory, but it delivers cleaner, hotter and more predictable results—especially for variable-quality dieback timber.

What moisture level should I target? – At or under 20% (ideally 15–18%). Look for Ready to Burn certification.

What helps with easy ignition? – Dry kindling and eco firelighters, plus a couple of small logs to build a hot core.

What if sections are crumbly? – Discard heavily decayed pieces. Prioritise dense, solid logs for efficient heat.

Conclusion

Can you burn ash dieback logs? Absolutely—when they’re properly dried and sensibly selected. For the cleanest, hottest and most reliable results, choose kiln dried logs packaged in crates or bulk bags, and light with quality kindling & firelighters. If you prefer to stock up, explore bulk buy logs with convenient delivery options.
