What Can You Burn in a Multi-Fuel Stove?

Multi-fuel stoves have become increasingly popular in the UK, offering versatility and efficiency for home heating. Understanding what fuels are suitable for your multi-fuel stove is essential for optimal performance, safety and compliance with local regulations. This article provides a comprehensive guide on the types of fuel you can burn in a multi-fuel stove.

What Can You Burn in a Multi-Fuel Stove?

Understanding Multi-Fuel Stoves

Before delving into fuel options, it’s important to understand what sets multi-fuel stoves apart from other heating appliances. Unlike wood-burning stoves, multi-fuel stoves are designed with a grate and ash pan, allowing them to burn a variety of solid fuels efficiently. The grate facilitates airflow beneath the fuel, which is crucial for the combustion of certain fuel types.

Suitable Fuels for Multi-Fuel Stoves

1. Wood Logs

  • Hardwoods vs. Softwoods: Hardwoods like oak, ash and beech are denser and burn longer, providing sustained heat. Softwoods such as pine ignite quickly but burn faster.
  • Seasoned or Kiln-Dried Wood: Always use wood that has been properly seasoned or kiln-dried, with a moisture content below 20%. Wet or unseasoned wood produces excess smoke and tar, leading to chimney deposits and reduced efficiency.

2. Smokeless Coal

  • Anthracite: A natural smokeless coal that burns hot and slowly, anthracite is an excellent choice for prolonged heat output.
  • Manufactured Smokeless Fuels: Brands like Homefire or Ecoal are designed for multi-fuel stoves, offering high heat and low emissions.
  • Compliance: In Smoke Control Areas, only approved smokeless fuels are permitted. Check with your local authority or consult the UK Smoke Control Areas guidelines for compliance.

3. Peat Briquettes

  • Composition: Made from compressed peat, these briquettes burn slowly and produce a steady heat.
  • Environmental Considerations: Peat is a non-renewable resource, and its use has environmental implications. Consider sustainable alternatives if environmental impact is a concern.

4. Eco Logs and Heat Logs

  • Compressed Sawdust Logs: These are made from recycled wood waste, offering a sustainable and efficient fuel option.
  • Advantages: They have low moisture content, burn consistently, and produce minimal ash.

5. Coke

  • Industrial Coke: A by-product of coal used in industrial processes, coke burns at high temperatures and is suitable for multi-fuel stoves with robust construction.
  • Usage: Ideal for overnight burning due to its long-lasting heat output.

Fuels to Avoid

1. Household Coal

  • Why Avoid: Traditional bituminous coal produces high levels of smoke and pollutants.
  • Regulations: The sale of traditional coal is being phased out in the UK to reduce environmental impact.

2. Wet or Unseasoned Wood

  • Issues: High moisture content leads to poor combustion, increased smoke, and creosote buildup in the chimney.
  • Solution: Use a moisture meter to ensure wood moisture content is below 20%.

3. Petroleum-Based Fuels

  • Hazards: Fuels like petrol or diesel are not designed for stoves and pose significant fire and explosion risks.
  • Safety: Only use fuels specifically recommended for multi-fuel stoves.

Best Practices for Fuel Usage

1. Storage

  • Dry Conditions: Store wood and other fuels in a dry, well-ventilated area to prevent moisture absorption.
  • Stacking Wood: Elevate firewood off the ground and cover the top while leaving sides open for airflow.

2. Regular Maintenance

  • Chimney Sweeping: Have your chimney inspected and swept at least once a year to remove soot and creosote.
  • Stove Servicing: Regularly check seals, grates and ash pans for wear and replace as necessary.

3. Environmental Responsibility

  • Sustainable Sourcing: Opt for fuels from sustainable sources, such as FSC-certified wood.
  • Efficiency: Using the right fuel improves stove efficiency, reducing fuel consumption and emissions.

Regulatory Compliance

1. Smoke Control Areas

  • Definition: Areas designated by local councils where emissions are regulated to improve air quality.
  • Approved Fuels: Only burn fuels listed on the Defra exempt fuels list.

2. Ecodesign Regulations

  • Standards: From 2022, all new stoves sold in the UK must meet Ecodesign efficiency and emission standards.
  • Implications: Ensure your stove and fuels comply to avoid penalties and contribute to environmental conservation.

Selecting the right fuel for your multi-fuel stove enhances performance, ensures safety and aligns with environmental and legal standards. Whether you prefer the traditional warmth of wood logs or the efficiency of smokeless coal, make informed choices to enjoy the full benefits of your stove.
