The pellet is a fuel biomass produced from virgin wood sawdust which is dried and compacted at high pressure without the addition of chemical binders or additives, and is a natural, ecological and high yield fuel, if preserved under the right conditions.

A pellet with good chemical-physical characteristics that is burned in the Fenix stove heater yields the majority of kilocalories and leaves a minimal amount of ash residue thanks to a unique ribbed heat exchanger.

The pellet has an energetic density that is approximately double that of wood and takes up very little space in the house or in the apartment.
