Description

Firewood calorific value groups

Firewood group Calorific value (kcal) Heat energy (KW)
Group I: Ash, Oak, Birch ***0 ***0 2,*5 2,*3
Group II: Pine, Alder ***0 ***0 2,*5 2,*1
Group III: Fir, Aspen ***0 ***0 1,*7 2,*0

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.

 

Timber weight and volume ratio
timber 1m3 weight (kg) ***0 kg volume (m³)
Oak **0 1,*5
Ash **0 1,*8
Birch **0 1,*1
Pine **0 1,*7
Alder **0 1,*9
Fir **0 1,*2

The heat value from different timber species you can calculate by comparing the heat value of solid timber and the density of timber. Example (based on average values): the 1m³ of solid Oak (Group I) timber firewood is the same as 1.*1m³ solid timbers of Pine (Group II), or 2.*6m³ of Fir (Group III), comparing the heat energy it generates.

Firewood is sold in 3 levels of moisture: fresh (****5%), air-dried (****5%) or kiln-dried (<*5%).

For natural air-drying we use the yard next-to warehouse. The boxes are kept with clearance of *0 cm to ensure **0° air ventilation and quick moisture release. During the storage, each box is covered with top to protect from direct rainfall.
