The majority of consumers that have experience in burning wood in a wood stove, or even camp fires, know that hardwood logs are often the fuel of their choice for their stove or camp fire to keep the fire going. A hardwood log has a higher efficiency than a same-size softwood log. The reason is simple. The hardwood is heavier because it is denser, and the wood is more compact, therefore, it burns for a longer period of time than softwood.
Regarding pellets, the production processes are the same. First, the fibres are dried, then reduced to smaller particles with a shredder, and finally, compressed into pellets. The result of this operation gives pellets with the same density, whether it is hardwood or softwood. A volume of softwood pellets has the same weight as the identical volume of hardwood pellets. The amount of heat depends strictly on the quality of the raw material used. Generally, softwood gives off more heat than hardwood.
