There are 3 families of wood:
-
hard hardwood (oak, beech, ash, chestnut, hornbeam, walnut…)
-
soft hardwood (poplar, willow, alder, birch…)
- coniferous trees (pine, spruce, fir, larch, D
ouglas fir…)
We recommend that you use firewood from the hard hardwood family. It has better heating power for an
equal volume. I.e., it has greater heating power for the same volume of wood burned.
Here is a table presenting the heating power, with equal humidity and volume, of the different species of
wood.
The heating power is presented on the basis of beech wood (set arbitrarily at 100).

Beech 100 Chestnut 89
Ash 97 Maple 84
