A log burner is one of the most rewarding features in a home - warm, atmospheric and efficient, when used correctly. But even the best log burner won’t perform well if it’s used in the wrong way.
Whether you’re new to log burners or have been using one for years, small mistakes can lead to poor heat output, wasted firewood and unnecessary smoke. Let’s take a look at 5 of the most common log burner mistakes and how to avoid them to get more heat, a cleaner burn and more value from every burn.
1. Burning wet or unseasoned firewood
The biggest mistake? Using logs that simply aren’t dry enough.
Firewood with high moisture content produces more smoke, less heat and leaves behind sticky tar (creosote) in your flue and burner. It also makes lighting your fire harder, wastes energy and can even damage your stove.
The fix:
Always choose kiln dried logs with less than 20% moisture content. They burn hotter, cleaner and more efficiently, making them suitable for all log burners. Look for the Ready to Burn certification logo for peace of mind that the logs are properly dried and suitable for immediate use.
Calido’s kiln-dried logs are all Ready to Burn certified and available in crates, nets and bulk bags, so you can choose the perfect format for your home and storage space.
2. Overloading your log burner
It’s tempting to pack your burner full of logs, especially on cold evenings. But cramming in firewood actually restricts airflow, causing the fire to smoulder rather than burn efficiently. The result? More smoke, less heat and wasted logs.
The fix:
The age-old saying “quality over quantity” applies here. Start with kindling and firelighters, build a solid flame, then add logs one or two at a time. You’ll get a hotter and cleaner burn, and use fewer logs overall. We recommend taking a look at our “How to light a fire” blog and the Top Down Firelighting Method.
3. Ignoring airflow and air vents
Your log burner doesn’t just burn logs – it burns oxygen. If the air vents or controls are set incorrectly, the fire can suffocate or burn too quickly.
The fix:
-
When lighting, open your air vents fully to give the fire maximum oxygen.
-
Once established, gradually adjust the vents to control heat output; don’t close them completely.
-
Keep your burner and flue free from ash buildup and blockages.
Good airflow = better heat, less smoke and cleaner glass.
4. Storing firewood incorrectly
You can buy the best kiln dried logs, but if they’re stored incorrectly, they’ll absorb moisture and lose efficiency.
Damp storage, uncovered log piles or leaving delivery bags outdoors can cause logs to build up moisture, especially in winter.
The fix:
Store your logs off the ground, with protection from rain but plenty of airflow. A log store, garage or sheltered side wall works well, just make sure there’s ventilation. Keep a smaller supply inside near your log burner so you always have dry logs ready. If you have your logs delivered and there is a downpour, don’t worry about this impacting the quality of your logs, as long as they’re not left for a long period of time, small amounts of surface water will evaporate off when burning.
Calido’s firewood crates and bulk bags make it easy to unload straight into a log store or dry storage area.
5. Using the wrong firewood for your needs
Different wood species burn differently. Some give you long-lasting heat, while others light quickly but burn through faster. Not matching the wood to your needs can affect warmth, efficiency and value.
The fix:
-
Softwoods like Pine are excellent for kindling and quick starts, but burn faster.
-
Always check log size – your burner may perform better with shorter, split logs.
Final tip: Get your log burner ready for winter
A quick annual sweep, clean glass and a checkover will help your log burner perform at its best all season. Combine that with the right logs, good airflow and correct storage and you’ll have efficient, cosy, cost-effective heat all winter long.
