Firewood is made of locally supplied Spanish timber. The wood species we use to make firewood are: 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 lm\ 1,8m3, 2m3 or 2,2m3 boxes or bags of 9.5 L, 21 L, 30 L, 40 L or 60 Liters. Basically, the timber has similar calorific value, only difference is the density. There are 3 categories for calorific value. This value is the energy (expressed in kcal or Kilowatts), released by burning exactly 1m3 solid timber. On the basis of density, the firewood species have their unique features. 1st group firewood burns at highest temperature and it is most suitable for house heating in bigger boilers. For the Barbeque fireplace or Sauna, the most suitable is Birch. The 3rd group firewood is burning at relatively low temperature; therefore it is safer for smaller furnaces to protect from cracking the chimney walls.
