Viessmann biomass boilers: efficient systems
for environmentally-friendly heat generation with
wood
This year, Viessmann will offer the following performance
enhancements for efficient, environmentally friendly heating with
wood:
-
The output range of the fully automatic pellet boiler
Vitoligno 300-C is being extended up to 48 kW. The boiler
fulfills all requirements of the second stage of the 1st
German Federal Emission Control Act (1. BImSchV).
-
The fully automatic biomass boiler Vitoligno 300-H for
woodchips and wood pellets is available from this spring
with additional rated heat outputs of 50 and 60 kW. When it
is operated with wood pellets, the emissions limits will be
adhered to which were introduced on January 1st, 2015, in
the second stage of the 1st German Federal Emission
Control Act.
Vitoligno 300-C: fully automatic compact pellet
boiler with additional output capacities
Vitoligno 300-C is a compact pellet boiler which particularly
impresses due to its convenient operation and degree of efficiency
of up to 95 percent. The boiler received the prestigious Vorarlberg
innovation award last year because of its low emission combustion
and this year the German Design Award for its design. It is now
available with five further output capacities up to 48 kW.
Fully automatic operation
With output capacities of 18 to 48 kW, the pellet boiler can be
charged either via the integrated suction system or a flexible
auger. With the suction system, the turbine integrated into the
boiler draws the wood pellets directly out of the pellet store or
pellet silo. With the flexible auger, the boiler is supplied with fuel
via a screw conveyor system. Automatic ignition (glow igniter) is
carried out by a power-saving ceramic heating element. The
stainless steel finned grate and all surfaces of the Vitoligno 300-C
in contact with ashes are cleaned automatically.
Convenient removal of ashes
The ashes are conveyed via the automatic removal procedure to
the ash bin trolley and are condensed at the same time. The
mobile ash bin trolley has a capacity of up to 40 liters, making it
much bigger than those of other pellet boilers. It needs emptying
only once or twice a year. The closed trolley means that disposal
is dust-free and very easy.
Convenient operation
Regulation of the boiler is as convenient as its operation. The
weather-compensated Ecotronic controller has a graphic display
with several lines of text and is programmable. Up to three heating
circuits plus DHW generation and a solar circuit can be controlled
in the standard design. A fourth heating circuit can be connected
via the KM bus system. The controls are all menu-guided. Offered
as an accessory, the wireless remote control Vitotrol 350 with
touch display enables users to obtain all information and use all
functions while in the living space.
Economical and environmentally friendly wood combustion
The innovative combustion technology ensures low fuel
consumption and low emissions with its stratified fire bed,
overhead charging of the combustion chamber, and output
modulations of 1:3. The Vitoligno 300-C pellet boiler thus fulfills the
strict emissions limits that have been in force since January 1st,
2015, in the second stage of the 1st German Federal Emission
Control Act (BImSchV). Additional secondary measures such a
fine dust filters are not required.
Coordinated accessories
A pellet hopper suitable for low-ceilinged rooms is also available
for the suction system. It can be set up directly next to the boiler
and filled, for example, with pellets from bags.
The annual requirement for pellets is usually stored in suitably
large pellet storage facilities. A modular 4/8 times suction probe
system is also available. It is controlled via the boiler control unit
and ensures that pellets are taken from the storage facility with an
even distribution. For this purpose, there is automatic switching
between the probes, according to how the pellets are distributed.
The new probe system also has the security function of "wind
back". If the pellet tubes are blocked, the suction direction of the
turbine is reversed and the tubes are automatically blown free. The
probes can be flexibly laid and are suited to very different
environments. They can be used in walled storage facilities with
and without a sloping floor, for up to two separate loading zones,
and storage facilities with unhelpful shapes (e.g. very elongated or
L-shaped spaces).

Vitoligno 300-H: biomass boiler with additional
output capacities for smaller heating loads
The biomass boiler Vitoligno 300-H can be fed either woodchips or
pellets. This means that the owners can choose between the two
fuels as they wish. Numerous functions allow for convenient, fully
automatic heat generation. Two new, smaller output capacities of
50 and 60 kW of rated heat output now extend the utilization
possibilities of the boiler.
Automatic functions for greater comfort
The numerous automatic functions include an automatic fuel feed,
automatic ignition, ash removal from the dual rotary grate when
required, and cleaning of the heat exchanger. The ash is
mechanically conveyed into the large mobile ash bin trolley.
Emissions below limits of the 2nd Stage of the
1st German Federal Emission Control Act (BImSchV)
With its weather-compensated controls and a wide modulation
range of 1:3, the boiler adjusts its output precisely to the current
heat demand and achieves a high degree of efficiency of 95 %. Its
staged combustion with a primary and secondary air feed ensures
low emissions. Vitoligno 300-H burns woodchips with a water
content of up to 30 percent. When burning pellets in accordance
with the standard ENplus-A1, the boiler meets the requirements of
the second Stage of the 1st German Federal Immission Control
Act.
Ecotronic control unit
The Ecotronic control unit with integrated start-up assistant,
illuminated display, and text display controls
-
up to four heating circuits with mixer (fourth heating circuit
is connected via KM bus module) or
-
two heating circuits with mixer and DHW generation or
-
a heating circuit with mixer, a solar circuit and DHW
generation.
Up to 24 heating circuits are possible in connection with the
remote control Vitotrol 350 (optional). Operation is easy thanks to
the well set out menu structure. The graphics-capable and easyto-read touch display with several lines of text makes it easy to set
all the relevant data.
Fuel feed
Fuel feed is carried out on the rear side of the new Vitoligno 300-H
with 50 and 60 kW output, in contrast to boilers with high output
capacities (80 and 100 kW). The boiler can therefore be placed
with the right side to the wall to save space.

Compact dimensions make it easier to transport and install.
Accessories such as storage and feed systems for pellets and
woodchips make installation simpler. All components are precisely
matched to one another and guarantee smooth working.
