WOOD
Freshly cut wood should not be directly used due to the moisture it contains. Damp wood not only burns less well, it releases damaging substances due to the low combustion temperature. Only wood that has been stored for a sufficient period meets the Federal emission regulations of 20% residual moisture! For most fireplaces, a residual moisture content of around 15% is ideal. The wood logs must be stored for 2 to 3 years in a dry location protected from the weather, or be dried by technical means. A wood moisture measurement device helps to determine the exact residual moisture of your wood. Treated, painted or coated wood may not be burned under any conditions. Coniferous wood such as fir or spruce is problematic: Since it contains a great deal of resin, it burns with an intense flame and tends to increased production of soot. Coniferous wood is not suitable for use in an open-hearth fireplace since a large number of sparks may result. (Danger of fire!) Wood logs burn best when most of the air needed for combustion is conducted into the firebox as a secondary air supply above the log. Only a small proportion of the air should be conducted into the firebox from below through the grate. The manufacturer's instruction manual should be referred to for the optimal setup of the heating appliance. |
Wood is the classic fuel for every fire. It heats up the fireplace quickly, burns freely and creates a romantic play of flames.
Wood is therefore the optimum fuel when the fireplace is only to be used for a short period. Firewood should principally only consist of untreated and unadulterated dry wood. Hardwoods such as oak and
beech, but also birch and fruit tree woods, are particularly suitable.
