FAQ
What types of logs are best suited for these burners?+
Seasoned hardwood logs, such as beech, ash, or birch, are ideal. Avoid green or unseasoned wood as it will burn inefficiently and produce excessive smoke. Ensure the logs are properly dried before use.
How often should I clean the ash from the burner?+
Regular ash removal is crucial for maintaining optimal performance. Aim to clean the ash every 2-3 days, or when the airflow becomes restricted. Excessive ash build-up can significantly reduce efficiency and create a safety hazard.
What size chimney do I need for these burners?+
These burners require a chimney with a minimum diameter of 6 inches (150mm). Ensure your chimney is in good condition, properly sized, and complies with current building regulations. A blocked or undersized chimney can cause dangerous backdrafting.
Are these burners suitable for modern airtight homes?+
While they offer high heat output, the efficiency of these burners may be affected by very airtight homes. Consider using a supplementary heating source during periods of low occupancy to minimise fuel consumption and maintain consistent temperature.
What safety measures should I take when operating the burner?+
Always operate the burner in a well-ventilated area, away from flammable materials. Ensure there is a carbon monoxide detector installed nearby and regularly test it. Never leave the burner unattended while burning.
How do I adjust the air intake for optimal combustion?+
The adjustable air intake allows you to fine-tune the burn rate. Increase the airflow for hotter flames and quicker heat output, decrease it for a more controlled, lower-temperature burn. Experiment to find your preferred setting.
What is the typical lifespan of these log burners?+
With proper maintenance and use, these cast iron log burners are expected to last 20-30 years. Regular cleaning and occasional repairs will help prolong their lifespan significantly.
Do I need a specialist installer for this burner?+
Due to the high power output of these burners (8kW), it is strongly recommended that you engage a qualified HETAS registered installer for installation. They can ensure correct chimney sizing, flueing and safety compliance.
What are the emissions standards for these log burners?+
These burners meet current DEFRA (Department for Environment, Food & Rural Affairs) exempt emission standards for solid fuel burning, minimising smoke production and reducing air pollution. Always use approved logs to maintain these standards.
Can I use smokeless fuel with these burners?+
While you can technically use smokeless fuel, it’s not recommended as they often contain additives that can damage the ceramic coating over time. Seasoned hardwood logs are the optimal choice for performance and longevity.
