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. Another
environmental aspect is the fact that timber contains hardly any sul-
phur, therefore almost no sulphur dioxide is created during combus-
tion.
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 graph 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 wood uneconomical, it also leads
to low combustion temperatures and high emissions plus tar deposits
inside the chimney.
Information on storing firewood
■ Split round logs from a diameter of 10 cm upwards. Enlarging the
surface area enables the wood gases to be expelled more quickly
and simply. The drying process is also accelerated during storage.
■ 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 should be created underneath the wood pile (e.g. in the
form of support timbers) 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 Minimum wood fuel requirements
Wood remnants, coarse woodchips and compressed shavings can be
used in the Pyromat Eco. The Pyromat Eco is ideal for the combustion
of logs. The wood should have an edge length between 45 and 50 cm
or up to 100 cm (depending on the boiler type: boilers for 50 cm logs
or 100 cm logs). The rated wood boiler heating output will only be ach-
ieved with dry wood with maximum 20 % water content (air-dried
wood). Wood of poorer quality and higher moisture content also
reduces the rated heating output and the length of combustion.
When using softwood (e.g. spruce), note that the energy per volume
unit is lower than with hardwood (e.g. beech). Softwood is therefore
suitable for "initial heat-up" - however, its use shortens the intervals
between recharging considerably and increases the volume to be used
(up to 44 %). Observe the requirements specified in the next chapter
relating to non-combustible substances and their limits for warranty
period claims. Deviations are only possible through written, system-
specific manufacturer declarations.
Substances
When procuring wood for combustion in a Pyromat Eco, ensure that
foreign objects (e.g. stones, metal parts, pieces of brick, plastics etc.)
are avoided. These would change the composition of the fuel and
therefore the critical parameters of the combustion process.
The values must not exceed or fall below the following limits (per kg of
dry fuel) for the non-combustible content (ash at an analysis temper-
ature of 815 °C):
Limit Comparison with natural wood from forests
Chlorine Cl mg/kg max. 300 10
Sulphur S mg/kg max. 1000 120
Total Cl, S mg/kg max. 1000 130
Ash content total g/kg max. 15.0 5.0
Alkali oxides in the ash (K2O and Na2O) g/kg max. 1.0 0.35
SB start of ash sintering °C min. 1000 approx. 1200
Exceeding the above limits will shorten the service life of the combus-
tion chamber and wood boiler. This also means that maintenance work
is increased and service intervals are reduced.
The proportion of dust-like and fine-grained materials should also be
minimised (in accordance with ÖNORM M 7133).
Origin, treatment and storage
Depending on the origin, wood can be natural wood (e.g. forest wood
and waste from sawmills), residual wood from wood processing plants
or waste wood (building rubble, furniture). The wood must be obtained
and cut to the desired size, and foreign objects deal with appropriately.
In addition to the requirement to adhere to ÖNorm M 7133, a max.
proportion of 5 % outliers in the fuel should be observed.
The length of the outliers must not exceed 16 cm (with a cross-section
of max. 5 cm²). The surface of the fuels should be roughened where
possible (e.g. through shredder, etc.). When using briquettes, ensure
compression is matched to charging. The maximum diameter is
60 mm.
Size of the woodchips
The Pyromat Eco is also suitable for the combustion of coarse woodchips. To prevent increased maintenance work, appropriate coarse wood-
chips in accordance with ÖNorm M 7133 should be used.

Further information
Ash and cleaning
Natural wood without bark has a percentage of ash less than 0.5 % of
the supplied fuel mass. All information regarding cleaning work is
based on natural wood with attached bark and an ash percentage of
0.8 %. The cleaning and maintenance work for other wood fuels should
be adapted according to the quantity, the specific weight and the ash
characteristics.
Changing fuels
Frequent and intensive changes in fuel quality, e.g. bulk density, water
content, dust proportion and ash content, can require a manual adjust-
ment of the combustion system parameters.
Non-wood biomass fuels
Non-wood fuels made from biomass such as needles, leaves, cereals,
straw, husks, fruit stones, etc. are unsuitable as fuels for fault-free
operation, and are therefore not permitted.
In some cases, the fuel properties (elemental composition, ash sinter-
ing point, etc.) differ considerably from those of wood. Combustion of
such fuels in a Pyromat Eco can lead to an impairment of the com-
bustion characteristics and increased stress on the fireclay lining and
the heat exchanger surfaces. Warranty claims can therefore only be
asserted when using approved fuels.

The Pyromat ECO was developed specifically for the combustion of
logs and represents state of the art combustion technology.
The Pyromat ECO log boiler has already proven itself thousands of
times. Charging from the top offers easy handling, control via the
Lambda probe guarantees low emissions, and the integral heat man-
agement ensures maximum convenience.
Clean and efficient combustion
The microprocessor control captures all details relevant for the oper-
ation and regulates the amount of heat required and provided. As a
result, the boiler system is monitored permanently in all operating pha-
ses, from heat-up and operation under load right through to burnout,
and is held within its optimum operating range by its motorised air
dampers. This guarantees clean and efficient combustion.
Large hopper
The Pyromat ECO offers the greatest operating convenience when
heating with logs thanks to its large charging chute. Log boilers in the
rated heating output range 40 to 75 kW can operate with logs of 0.5 m
length; in the range 85 to 170 kW, the hopper width increases to
1080 mm, ensuring convenient charging even with logs of 1 m
length.
With oil burner connection
The Pyromat ECO is also approved as an oil boiler compliant with EN
standard; the necessary connections are already in place. Fitting an
oil burner may, for example, help to bridge holiday times when manual
charging with logs is not feasible.
The Pyromat ECO is particularly suitable for the combustion of logs,
wood briquettes and wood remnants, either loose or in pieces.
The Pyromat ECO boiler system has been tested in accordance with
the latest quality criteria to EN 303-5 "Heating boilers for solid fuels",
and can be brought into circulation with CE designation (direc-
tive 98/38/EC etc.) and VKF approval.

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.
