1.1 Principles of log combustion for generating heat
Units of measurement for wood fuel
The units of measurement commonly used in forestry and the timber
industry for wood fuel are solid measures of timber (smt) and stacked
cubic metres (stcm). The solid measure of timber (smt) describes
1 m3 of solid timber mass in the form of assorted round timbers.
The stacked cubic metre (stcm) is a measure for stacked or tipped
wood, measuring a total volume of 1 m3, including air gaps. On aver-
age, one solid measure of timber equals 1.4 stacked cubic metres.

Calorific and emission values
Timber is a renewable fuel. During combustion, on average approx.
4.0 kWh/kg units of energy are released.
The table shows the net calorific value of various types of timber with
a water content of 20 %.

1 litre of fuel oil can be replaced by 3 kg of timber, considering the usual
efficiencies. A stacked cubic metre (stcm) of beech corresponds to the
energy of approx. 200 litres of fuel oil or 200 m3 of natural gas. There-
fore burning wood contributes to the preservation of the finite reserves
of oil and gas.
Timber has a generally neutral CO2 balance, as the CO2 created during
combustion is immediately reabsorbed into the photosynthesis cycle
and therefore contributes to the formation of new biomass. A further
aspect relevant to environmental considerations is the fact that timber
contains hardly any sulphur, therefore almost no sulphur dioxide is
created during combustion.
Influence of moisture on the net calorific value
The water content of timber substantially influences its net calorific
value. The more water timber contains, the lower its net calorific value,
since the water evaporates during combustion and consumes energy
in the process.
Two measures are used to specify the water content:
■ Water content
The water content of timber is its water mass as a percentage of the
total timber mass.
■ Timber moisture level
The timber moisture level (hereafter referred to as moisture or mois-
ture level) is the water mass as a percentage of the total timber mass
excluding water.
The diagram shows the relationship between the water content and
the moisture level, as well as the dependency of the net calorific
value.

Freshly cut timber has a moisture level of 100 %. During storage over
one summer, this moisture level reduces to approx. 40 %. During stor-
age over several years, this moisture level reduces to approx. 25 %.
The diagram shows the dependency of the net calorific value on the
water content, using spruce as an example. With a water content of
20 % (moisture level 25 %), the net calorific value is 4.0 kWh/kg.
The net calorific value of timber stored over several years is approx.
twice that of freshly cut timber.
Storage
Not only is the combustion of moist timber uneconomical, but it also
leads to low combustion temperatures and high emissions plus tar
deposits inside the chimney stack.
Information on storing wood:
■ Split round timbers that have a diameter of 10 cm or more.
■ Stack the logs in a ventilated and preferably sunny spot underneath
a rain canopy.
■ Stack the logs with generous air gaps to enable the flowing air to
carry off the dissipating moisture.
■ A hollow space should be created underneath the wood pile, e.g. in
the form of storage beams, to allow moist air to escape downwards.
■ Never store freshly cut wood in a cellar, as air and sunshine are
required for drying. However, dried wood can be stored in a well
ventilated cellar.
1.2 Fuels
This boiler is only suitable for the combustion of natural logs. Logs
should ideally be 45 to 50 cm in length. Do not use the appliance to
burn fuels such as sawdust, fines (wood or coal), coke, woodchips,
briquettes or logging residues. If shorter logs are used, they should be
layered without air gaps. 25 cm logs can be inserted in line one after
another. Logs of 33 cm in length cannot be layered without gaps
between them and should not be used as they will reduce the boiler
output and increase the risk of ineffective gasification.
The rated boiler heating output will only be achieved with dry wood
with maximum 20 % water content or maximum humidity of 25 % (air-
dried wood).
When using softwood, about 44 % more (volume) is needed to produce
the same amount of energy as when using hardwood.
Wood of poor quality and high moisture content reduces the rated
heating output and the length of combustion.
For combustion it is important to use split logs. Splitting the wood –
preferably straight after felling – makes a significant contribution to
improving the combustion process. Enlarging the surface area enables
the wood to be degassed more quickly and simply. In addition, split
logs dry more quickly.

The Vitoligno 200-S biomass boiler is a good alternative to an oil or
gas heating system: Wood is affordable and CO2 neutral.
The Vitoligno 200-S is a high quality wood gasification boiler with out-
put stages of 20, 30, 40 and 50 kW. With outputs of 30, 40 and 50 kW,
it operates in modulating mode and adapts continuously to the current
heat demand. In the 20 kW output stage, the wood gasification boiler
operates solely under full load.
Up to 50 cm long logs are easily handled by the large stainless steel
hopper. The combustion time is up to twelve hours without recharg-
ing.
Heat-up in just three minutes
The heat-up process is complete after just three minutes. The extrac-
tion of oxygen from inside the hopper means that the logs smoulder
rather than burn. There is no flame, as the wood gas does not have
the oxygen required to build a flame. The combustible wood gas burns
cleanly in the combustion chamber at high temperatures, under partial
as well as under full load.
Convenient with automatic ignition
Automatic ignition is available for heating the fuel. The ignition timing
can be programmed using the Ecotronic control unit. This is especially
practical for returning home after a holiday to a prewarmed apart-
ment.
Ecotronic digital control unit
The menu-guided Ecotronic boiler control unit makes operating the
Vitoligno 200-S particularly easy. Up to three heating circuits can be
controlled. Alternatively to one heating circuit, DHW heating and heat-
ing water can be controlled conveniently via the buffer cylinder man-
agement system.
Easy cleaning
The heat exchanger of the Vitoligno 200-S can be cleaned easily and
quickly using a mechanical lever mechanism. The wood burns with few
residues, due to the high combustion efficiency up to 92 percent. An
ash box with a lid is available for taking the ash to the waste container
without any mess.

T
APump
BControl valve
CPt1000 temperature sensor
DContact temperature sensor
When the temperature at the cylinder temperature sensor falls below
the set value, the circulation pump for cylinder heating starts and the
DHW cylinder is heated.
The flow rate of the heating water is controlled via the return temper-
ature (flow control). This results in optimum stratification of the buffer
cylinder with sustained high temperature at the cylinder flow. The
heating periods (individual day and seven-day program) can be adjus-
ted via the integrated time switch.
Standard delivery
■ Pt1000 temperature sensor (7 6 mm, L = 2000 mm) with sensor
well
Note
The standard delivery does not include positions A and B.
Long-distance heat line (sub-distributor)

CContact temperature sensor
DPump
EControl valve
Via a long-distance heat line, a building is supplied with separate heat
distribution. The long-distance line is controlled upstream according to
the demand of the heating circuits. The heating circuits of the separate
heat distribution must be controlled via the Vitotrol 350.
Note
The contact temperature sensor C is part of the standard delivery of
the controller module.
Note
The long-distance heat line can only be used if Köb extensions are
also being used in the sub-distributor.
Adjacent building
The line to the adjacent building is controlled with weather compen-
sation via the heating circuit control unit.
An adjacent building line (long-distance heat line) can be implemented
using a controller module for the adjacent building and the required
controllers.
Mixer extension kit
The standard Ecotronic version can be customised with extension kits
for heating circuits with mixers. Heat consumers or DHW cylinders can
be incorporated into the control system.
Note for extension kits
For DHW heating, the following must be ordered separately:
