Buying Guide & FAQ

What does a 5kW multi fuel stove mean?

The 5kW figure refers to the stove’s heat output. It is one of the first specifications to check because the required output depends on the room and property rather than simply choosing the largest stove available.

A stove that produces more heat than needed may make the room uncomfortably warm, while insufficient output may leave the space struggling to reach the desired temperature.

Which fuel can a multi fuel stove burn?

Check the individual manufacturer’s specification rather than assuming every multi fuel stove supports exactly the same fuels.

The products here include combinations of:

  • Wood logs
  • Smokeless fuel
  • Coal
  • Peat briquettes

The AmberGlo model, for example, specifically lists wood, coal, smokeless fuel and peat briquettes, while the HEATSURE model states that it can burn wood and smokeless fuel.

Does the stove material matter?

Cast iron is common on traditional multi fuel stoves and can give the appliance a substantial appearance. Some models combine different materials instead. The AmberGlo uses a steel body with a cast iron door, while the NRG 5KW model has a steel body and cast iron door.

What should you check before installation?

Flue requirements are particularly important. Check the required diameter and whether the stove provides top, rear or interchangeable flue options.

The HEATSURE model is compatible with a 5-inch flue and includes a flue connector. The AmberGlo also uses a 125mm (5-inch) flue and allows top or rear positioning. The fourth model specifically states that its flue pipe is not included.

What other specifications should you compare?

Beyond the headline 5kW output, useful specifications include efficiency, dimensions, fuel compatibility, flue size and maintenance features.

A removable ashpan can make cleaning easier, while a larger viewing window may be preferable if seeing the fire is an important part of the stove’s appeal. Weight and physical dimensions are also worth checking carefully before installation.

What size room is a 5kW stove suitable for?

The suitable room size depends on factors including insulation, ceiling height, room layout and the property’s construction. One of the supplied NRG models states heating coverage of up to 80 square metres, but this should not be treated as a universal figure for every 5kW stove.

Do 5kW multi fuel stoves need a flue?

These stoves require an appropriate flue arrangement for installation, but the exact configuration varies. Check the required flue diameter, outlet position and whether a flue pipe or connector is included with the particular stove.
