Firewood is made of locally supplied timber. The wood species we use to make firewood are beech, Ash, Oak, Birch, Alder, Pine, and Fir. Each log can be cut into pieces of 25, 30 or 45 cm, split 4-6 times for 8-15 cm diameter and stacked into 1m³, 1,8m³, 2m³ or 2,2m³ boxes or bags of 9.5 L, 21 L, 30
