Lately, the mistaken belief has appeared that the best pellets are made from beech wood.
Conifer wood has a higher lignin content compared to cellulose. Because lignin has a higher calorific value, the wood of conifer trees thus has a higher calorific value.

Enerles pellets have a high calorific value of 5.3 kWh/kg. In comparison, beech wood pellets have a 5-10 % lower calorific value.
