What is a multi-fuel stove?

In contrast to traditional wood-burning stoves, multi-fuel stoves are a versatile heating option that gives you the freedom to choose between different solid fuel types. Because of this, many see them as a more convenient option.

How does a multi-fuel stove work?

A multi-fuel stove works the same way as a wood burner, with one crucial difference. These appliances burn multiple fuel types, such as smokeless coal and wood. Here's a detailed look at the workings of a multi-fuel stove:

Fuel loading and ignition

Unlike the flat surface of a wood burner's firebox, a multi-fuel stove typically comes with a grate. This allows various fuel types to be used safely and efficiently. The fuel is loaded into the firebox, where you ignite it using kindling or firelighters.

Air circulation and combustion

Once the fuel is ignited, proper air circulation is essential for efficient combustion.

  • Primary air: Enters below the grate and fuels solid fuel combustion.
  • Secondary air: Enters above the fuel, helping to burn off volatile gases (especially when burning wood).
  • Tertiary air: Some modern multi-fuel stoves feature tertiary air inlets. These enhance the combustion efficiency even further.

Multi-fuel stoves are equipped with air controls. These allow you to adjust the airflows to control the burn rate.

Grate and ash pan design

Most multi-fuel stoves have a grate and ash pan. This helps in the efficient burning of smokeless coal or other mineral fuels. Ash falls through the grate into the pan, ensuring the ash build-up does not interrupt airflow.

Heat distribution

The fuel burning in the firebox generates heat, which the stove distributes into the room. This is done either through radiation, where the hot surface of the stove heats up the room, or by convection, where the stove draws in cold air from the room, heats it, and directs it back out into the space.

Emission control

Modern multi-fuel stoves are designed to minimise emissions, regardless of your chosen fuel. Efficient combustion and using secondary and tertiary air supplies help reduce the output of harmful substances, keeping your home clean, healthy, and warm.

Why buy a multi-fuel stove?

Choosing a multi-fuel stove is a decision that comes with various benefits. Let's explore some of the main reasons why you might choose a multi-fuel stove rather than a standard wood burner:

Fuel versatility

Firstly, multi-fuel stoves are more flexible with the ability to burn wood, smokeless coal, and other solid fuels. This can be especially useful if certain fuels become expensive or hard to get in your area.

As we all know, economic and environmental factors can affect the prices of various products, including fuel. A multi-fuel stove frees you from being tied to a single fuel source, making it easier to adapt to changing circumstances.

Energy efficiency

Secondly, modern multi-fuel stoves are a highly efficient choice. They are designed to achieve optimal combustion. As a result, this means you'll get more heat output for the same amount of fuel.

What's more, by choosing to burn eco-friendly fuels like smokeless fuel or sustainably sourced wood, your multi-fuel stove can help you reduce your carbon footprint.

Cost-effective home heating

Finally, the flexibility to switch between different fuels can help you save even more money on heating your home, especially if you can source affordable, local fuel options. Depending on the size of stove you choose, you can use your multi-fuel stove to heat your entire home or supplement your central heating. This has serious potential to reduce your overall heating costs.

What size multi-fuel stove do you need?

Choosing the correct size multi-fuel stove is crucial in the buying process. It impacts your stove's heating efficiency and your living space's overall functionality and aesthetics. Here's how to choose the right stove size:

Multi-fuel stove output ratings

Multi-fuel stoves are rated by their maximum heat output in kilowatts (kW). A common rule of thumb is that you'll need 1kW for every 14 cubic metres of space. You can use our stove size calculator, but if you're interested in the maths, here's how it works:

  1. Measure the room: Firstly, determine the room's length, width, and height in metres.
  2. Calculate the requirement: Next, divide the total cubic metres by 14 for a well-insulated room, 12 for a room with average insulation, and 10 if the room has poor or no insulation. The result is the approximate kW output you'll need.
  3. Example: If a room is 7m long, 4m wide, and 2.5m high, the volume is 70 cubic metres. Dividing by 14 gives you a requirement of 5kW for that room. If the room has poor insulation and you divide by 10, you'll need a multi-fuel stove with an output of 7kW.

Understanding your heating needs

Larger rooms require a multi-fuel stove with a higher heat output, such as the Mendip Loxton 10 or the Parkray Aspect 14.

For average-sized rooms, a multi-fuel stove with average output, usually around 5-6kW, will usually suffice. Some examples include the Portway Arundel Multifuel, the Woodford Didsbury 5, and the Woodford Lowry.

Finally, for smaller rooms, conservatories, glamping pods, or log cabins, consider a multi-fuel stove with a smaller heat output. The Mendip Loxton 3 SE or the Beltane Brue are excellent choices.

Bear in mind that some multi-fuel stoves have different heat outputs depending on the type of fuel you burn.

Important considerations

  • Insulation and windows: If the room is poorly insulated or has many windows, you will likely need a multi-fuel stove with a higher kW rating.
  • Open-plan spaces: If you plan to use the multi-fuel stove to heat an open-plan area, you may need to consider additional factors or have a professional assess the room.
  • Avoid oversizing: A multi-fuel stove that is too large for the space it's heating can lead to inefficiency and overheating. On the other hand, if your multi-fuel stove is too small, it may not provide sufficient warmth.

Multi-fuel stove physical size considerations

You should choose a multi-fuel stove that fits well within the room without overwhelming the space or appearing too small. Check the dimensions of the stove before you buy it and ensure it will work well within the intended area.

Additionally, it's crucial to be aware of clearances. Check the manufacturer's guidelines for necessary clearances around the stove, often called distance to combustibles. This outlines the space you must leave clear from flammable materials, such as walls, furniture, curtains, or separate log storage.

Compatibility with existing infrastructure

Ensure the multi-fuel stove's flue outlet fits your existing chimney or flue system. You must have one professionally installed if you do not have a current flue system or chimney. You can fit a twin-wall flue system for a multi-fuel stove in a home without a chimney.

Choosing the right multi-fuel stove style for you

Just like wood-burning only stoves, multi-fuel stoves aren't purely functional. They also contribute to the aesthetics of your home. They're available in various styles and can match your décor, whether you like traditional, modern, or something in between.

Traditional multi-fuel stoves

Traditional multi-fuel stoves like the Gallery Classic 5 Compact, the Stovax Stockton 3, and the Go Eco Excel Wide have a design that echoes the past. They often feature cast iron construction, a timeless appearance, and ornate details.
