In this guide, we’ll break down the best wood for log burners, explain the importance of seasoning, highlight which wood species to look for, and show you how to measure and manage moisture content. Whether you're new to wood burners or looking to fine-tune your stove setup, this guide will help you burn better and cleaner.

​

​

🔥 Why Wood Choice Matters for Your Log Burner

• Efficiency: The right wood can produce more heat per log.

• Safety: Low-moisture logs reduce creosote buildup and chimney fire risk.

• Eco-Friendliness: Seasoned hardwood burns cleaner and complies with EcoDesign 2022 regulations.

• Cost-Effectiveness: Burning the right logs means fewer top-ups and longer-lasting warmth.

✅ Tip: DEFRA-approved stoves perform best with properly seasoned hardwood.

​

🪵 Best Wood Species for Log Burners

​

Ash

Arguably the best all-rounder. Burns well even when not fully seasoned. High heat output, low smoke. Low moisture content when felled.

🔥 Verdict: Arguably the best all-rounder.

​

Oak

Very dense, slow-burning. Requires long seasoning (2+ years). Gives out a steady, long-lasting heat.

🔥 Verdict: Very dense, slow-burning.

​

Beech

Burns hot and clean. Must be well-seasoned to avoid sparking. Easier to split than oak.

🔥 Verdict: Burns hot and clean.

​

Birch

Quick to light, moderate heat. Pleasant scent, low smoke. Burns faster than ash or oak.

🔥 Verdict: Quick to light, moderate heat.

​

Hornbeam

Harder and denser than oak. Very long-lasting embers. Rare, but a premium choice.

🔥 Verdict: Harder and denser than oak.

🌦️ What is Seasoned Wood?

​

Seasoned wood is wood that has been dried to reduce its moisture content to below 20%. Freshly cut (or “green”) wood contains up to 60% water, making it difficult to burn and highly inefficient.

Burning wet logs:

• Produces more smoke.

• Creates harmful creosote.

• Causes blackened stove glass and poor airflow.

• Wastes heat evaporating water instead of warming your home.

How to Season Wood at Home:
1. Split logs to increase surface area.
2. Stack in a well-ventilated, sheltered area.
3. Raise off the ground on pallets or crates.
4. Cover the top but leave the sides open for airflow.
5. Store for 12–24 months depending on species.

🕒 Oak and beech take longer to season than ash or birch.

​

💧 Understanding Moisture Content

​

Moisture content is the most important measurement when assessing firewood quality. Your logs should always be under 20% moisture for efficient and clean burning.

How to Check Moisture:

​

• Use a moisture meter (available to buy here!).

• Insert into the middle of a freshly split log.

• Look for readings under 20%.

📏 Always test multiple logs from a batch to get an average reading.

​

🪓 Kiln-Dried vs Air-Dried Logs

​

Kiln-Dried Logs:

• Dried in a controlled environment.

• Guaranteed low moisture (<20%).

• Ready to burn immediately.

• More expensive.

Air-Dried (Seasoned) Logs:

• Naturally dried outdoors.

• Can take over a year to season.

• Cheaper but needs storage space.

🔥 Look for Ready to Burn certified logs for peace of mind and EcoDesign compliance.

​

🏷️ Ready to Burn Scheme (UK)

​

Since the introduction of EcoDesign 2022, all wood sold in volumes under 2m³ must be certified as "Ready to Burn".

This guarantees:

• Moisture content below 20%.

• Cleaner, more efficient combustion.

• Compliance with government regulations.

​

❌ Avoid These Woods

​

Some types of wood are unsuitable or even dangerous in a log burner:

• Treated Wood: Contains chemicals that release toxic fumes.

• Painted/Coated Wood: Similar issue with harmful emissions.

• Resinous Softwoods: Like pine or larch; can clog flues with sap.

• Green Wood: Too wet, creates smoke and soot.

🚫 Never burn MDF, chipboard, or household rubbish.

​

🔥 Tips for Burning the Right Way

​

1. Build a small fire first with kindling and softwood.
2. Add a couple of hardwood logs once established.
3. Keep your air controls open until the fire is well underway.
4. Maintain good airflow and don’t overfill your stove.
5. Regularly check and clean your chimney.

📦 Buying Logs: What to Look For

​

Whether you're buying logs online or from a local supplier, look for:

• Moisture content under 20%.

• Clearly labelled species (ash, oak, etc.).

• "Ready to Burn" certification.

• Properly netted, stacked or bagged logs.

• Reputable, eco-conscious suppliers.

💡 Many retailers now offer log subscriptions or bulk delivery deals—ideal for winter prep.

​

​

Choosing the best wood for your log burner doesn’t have to be complicated. Stick to well-seasoned hardwood, keep moisture under control, and follow best burning practices. Not only will your stove run better, but you'll enjoy warmer evenings, cleaner air, and lower costs.
