Heating with pellets
Pellets – "Liquid wood"
Pellets are standardised, small cylindrical rolls comprising 100% natural wood residues (wood shavings, sawdust, etc.). The dried wood residues are ground and compressed into wood pellets under high pressure using special presses. No binding agents or additives are required, and neither are they permitted. Manufacturing wood pellets from dried wood shavings takes about 1% of the energy contained in the fuel, or about 5% when moist sawdust is used. The "liquid wood" therefore has the best energy efficiency of all fuels.
