Multi-fuel stoves, on the other hand, can be used to burn a variety of materials other than wood. Multi-fuel stoves are capable of burning smokeless fuels, anthracite and peat/turf briquettes and are designed to burn them effectively. These appliances usually include either a raised grate with moving bars or a central riddling grate and ashpan. These options are designed to de-ash the fuel to maintain effective combustion conditions. That’s because unlike wood burning stoves, optimum combustion and efficient burning require the fuel to be de-ashed. The ashpan included in the multifuel stove underneath the grate is needed to both collect ash and enable its safe removal. Both woodburning and multifuel stoves are highly efficient and have pretty much the same heat output.
