The F55 Avanti Midi stove is more imposing than the F40 version, for larger openings and spaces. It offers an even greater view of the fire and extra heat output - up to 8kW - as well as all the features of the Riva range such as cleanburn technology, airwash system to help keep the window clear, multi fuel operation and external riddling. This stove is suitable for burning seasoned logs, smokeless fuels and peat/turf briquettes.
