2.4. Wood types and calorific value
A wood’s efficiency does not depend only on its type, but also on its humidity, as well as the temperature of the combustion chamber.
For more efficient and longer burning, without emission of hazardous substances, woods must be dry. Ideally, their humidity percentage must
not exceed 10% to 15%.
If this percentage is over 20%, the wood is not burned properly, whereas if the piece of wood has been cut recently, the humidity is over 60%
making it unsuitable for burning. The reason for that is that the fire will be weak and pale and will produce dense smoke, unburned tar and
creosote, soiling the ceramic glass and the flu.
It is preferable to get your wood supplies during the summer months and store them, to ensure better combustion quality during the winter.
Useful tips
Always choose dry firewood.
Avoid wood that pops (chestnut, conifers such as cedar, spruce and pine), as they may damage your wood stove or the flue.
Pay attention to the size of the logs. Good firewood must have been cut at least twice.
You should prefer oak, beech, olive wood, which is hard wood with high density since they will burn for longer.
Briquettes
They ignite very easily, and burn slowly. They are economically advantageous because you will burn smaller quantities compared to common
firewood and they are easily stored. Also, you have less quantity of ashes vs. to wood.
Birch
It’s a soft wood that ignites easily with great thermal energy production. It produces less smoke and ash compared to other wood and burns
silently. The same characteristics apply for lime and chestnut.
