Best Log Burners — Multi-Fuel (2026)

The required flue varies depending on the burner’s design and the fuel being burned. Multi-fuel burners typically need a swept flue system to handle smoke from wood and anthracite, while smokeless fuel briquettes often necessitate a taller, more restricted flue to control emissions effectively.

Yes, most multi-fuel burners can burn anthracite, but it’s crucial to adjust the air inlets correctly. Anthracite produces significantly less smoke than wood and requires a lower combustion temperature – typically achieved with restricted airflow.

A common starting point is around 70% wood and 30% anthracite, but this depends on your burner model and personal preference. Experimenting with different ratios under controlled conditions can help you find the most efficient burn.

The frequency of ash pan cleaning depends on usage, but generally aim to empty it after every few burns. A full ash pan reduces efficiency and increases smoke emissions, so regular maintenance is key.

Modern multi-fuel burners with catalytic converters are designed to significantly reduce emissions compared to older designs. However, it's important to burn only appropriate fuels and maintain the burner correctly for optimal performance and reduced pollution.

Installation must comply with Building Regulations Part L regarding smoke control. Ensure adequate ventilation, install carbon monoxide detectors, and follow all manufacturer’s instructions diligently – professional installation is highly recommended.

The air inlet controls the amount of oxygen available for burning, directly impacting temperature and smoke production. Wider inlets provide more oxygen for a hotter flame with more smoke; narrower inlets reduce oxygen for a cooler, cleaner burn.

Anthracite coal is a dense, hard form of coal known for its low smoke output when burned correctly. Its popularity stems from its consistent burning properties and reduced maintenance requirements compared to softer fuels like wood.

Yes, many multi-fuel burners are suitable for smokeless fuel briquettes, but ensure the burner is designed for this purpose. Adjust air inlets carefully as briquettes produce less smoke than traditional wood.

Regularly check the burner’s glass door for carbon build-up and clean with a suitable glass cleaner specifically designed for stoves. Inspect the air inlets for blockages and ensure the catalytic converter (if fitted) is functioning correctly according to manufacturer guidelines.
