The wood
– Choice and usage
The Jidé fireplaces are designed to burn hard wood logs only.
The quality of wood is important.
“Green” wood contains a lot of water (approx. 50 %).
“Dry” wood, kept outside for 24 months covered and well ventilated, still contains 15 %
water.
Damp wood is more difficult to consume, presents a lower calorific power and pollutes the
environment.
Damp smoke has disadvantages, for example a reduced draft and the formation of tar in the
flue and on cold surfaces (the window for example).
Split wood presents better combustion and will improve the operation of your fireplace.
The calorific value of wood depends on its type, and the volume of wood required for the
same quantity of heat differs according to this choice. Thus, the “hard” wood varieties such
as beech, oak, whose density is high, will require a lower quantity than other low density
species:
Density
Hornbeam ........................................................................................ 400 – 500 kg per m³
Oak ................................................................................................... 380 – 480 kg per m³
Beech ............................................................................................... 350 – 450 kg per m³
Birch ................................................................................................. 300 – 400 kg per m³
Poplar .............................................................................................. 250 – 350 kg per m³
