  • Upside down flame

    It is called inverted flame or reverse flame for the position of the combustion chamber, located below the compartment in which the wood is loaded.

  • Wet Flue Ways

    Wet Flue Ways has been created to maximise the surfaces which come into contact with the water, optimising the heat produced through the combustion process and reducing heat loss and fuel waste.

  • Turbulators

    The helix shape of the turbulators reduces the speed of the emissions released by the combustion process, increasing machine performance and keeping the exchanger clean.


Wood fuel – Removable ash drawer with seal closure – Chamber combustion totally submerged – Upside down flame – High efficiency thanks to the Lambda probe – Painted steel sides – Independent regulation of primary and secondary air


This product meets the criteria for eco-compatible design and complies with the energy efficiency and particulate emissions requirements established by the European Ecodesign 2022 Regulation for domestic biomass appliances.
