The types of heating materials that have been used so far in Scandinavia and the Baltic States, regardless of their effect on the environment and just for the purpose of convenience are:

Stone coal
Electricity
Gas

These types of fuel, however, are accompanied by non-recommendable side effects like:
– they favour the occurrence of allergies and diseases
– they reduce the working life of the furnaces
– they have a damaging effect on nature
– they leave high amounts of residues from their burning (ash, soot, grime, pitch etc.)
– their cost is too high in relation to the amount of energy obtained from them

Wood briquettes form a natural and environmentally friendly type of fuel that contains no additives. The solidity of the briquettes is ensured by the naturally adhesive substance contained in any tree and plant – lignin (resin). The pressed briquettes have a very high degree of density and may have a weight of 1 t/ m3 and thus require only very little storing space.

The pellets are manufactured with a diameter of 6mm as well as 8mm. Both options may be used simultaneously in most of the pellet burners. Pellets are used in residential households as well as in automated systems for industrial purposes.
