6. Fuel
The specified fuel is dry split logwood of 150 - 250 mm diameter, at least 2 years old, with mois-
ture content of 12 % to 20 %, 15 - 17 MJ.kg
-1
caloric power and maximum length 550 - 750 mm (based
on the boiler type).
The boiler is intended for combustion of soft or hard wood logs.
Do not use a small fuel and wood waste for heating.
Basic wood burning data
You can ensure maximum output and a long service life if you burn wood which has been left for
at least 2 years to dry. The following graph illustrates the relationship of moisture content to heating
capacity of the fuel. The energy content declines dramatically with increased water contents.
Example:
Wood with 20 % moisture contents has thermal power of 4 kWh /1 kg of wood
Wood with 60 % moisture contents has thermal power of 1.5 kWh /1 kg of wood
●
Example – spruce wood which has been stored for 1 year under shelter – see graph
The graph illustrates the boilers maximum
output with wet fuel.
kW
DC105S - 84
DC150S - 120
Boilers are not suitable for burning wood with moisture content lower than 12 %.

Raw wood does not burn easily, produces a lot of smoke and substantially decreases
the service life of your boiler and chimney. Boiler output drops as low as 50 % and fuel
consumption doubles.
