pieces of wood, paper, oil, plastic or other materials as fuel.
Wood pellets are zylindrical and made from wood scraps without additives or chemical binders. The pellets must show standard simen-

For the best possible combustion use pellets with the quality A1 according to ISO 17225-2:2014, with the seal ENplus-A1 and ÖNORM.
These standards comprise requirements in pellet quality, test regulations, control of production and labelling.
