Futureproof and ecient
heating technology for all requirements
In Western industrial nations, heat generation for residential and commercial buildings
accounts for the largest proportion of energy consumption – at the same time this sector
oers the greatest savings potential. Advanced and energy ecient heating systems from
Viessmann are in use around the world, not only in many private households, but also in
numerous major projects. There, they make an important contribution to the sustainable
protection of finite energy reserves.
Advanced heating technology has certainly been put to the test in these projects, which
involved working with historical buildings, impressive industrial complexes and large scale
industrial and commercial buildings. Viessmann’s innovative solutions always successfully
rose to the challenge, however.
The comprehensive range of medium and industrial/commercial boilers does not only include
Viessmann products, but also heat generators and air conditioning units produced by the
extended branches of the Viessmann Group, that is Köb, Mawera, KWT, ESS, BIOFerm and

Introduction
![](asset-7.png)
Saving energy and protecting the climate
Viessmann is aware of its responsibility for the sustained protection of the environment.
Its company philosophy and products focus on this.
"Nothing is so good that it cannot be
improved". This maxim is at the heart of the
Viessmann company's principles. In this
industry, Viessmann can rightfully claim to be
the leader in quality and technology, and as
such, aims to continually set new standards.
Of course, this applies in particular to
the company's product range, which is
consistently geared towards significantly
lowering the consumption of fossil fuels,
and gradually replacing them with renewable
sources of energy.
At around 40 %, the heating market actually
accounts for the largest proportion of energy
consumption. The rest is shared by goods
transport, personal transport and power, at
20 % each. These are values that can also be
applied, to some extent, to other industrial
countries. Rising energy costs mean the
emphasis is on reducing the consumption of
fossil fuels as quickly as possible.
Condensing technology oers the
greatest energy eciency
Taking the overall investment and current
energy prices into consideration, condensing
technology is the most economical
alternative. Viessmann condensing boilers
convert up to 98 % of the energy used
into heat. At the same time, condensing
technology is also futureproof, as biofuels can
already be mixed with conventional fuels.
An investment in advanced condensing
technology enables substantial savings
to be achieved that have a positive eect
particularly on tight commercial and municipal
budgets.
Users will also make an eective contribution
towards the sustained protection of the
environment by preventing unnecessary
CO2 emissions.
Viessmann always oers the right solution –
with its comprehensive range of medium
and industrial/commercial boilers as well as
its powerful heating systems for sustainable
fuels, particularly biomass.
6/7
Viessmann works consistently on new,
environmentally responsible solutions.
The result is environmentally friendly,
cost eective and ecient heating
systems.
Viessmann oers ecient and
energy-saving heating systems
for oil and gas in the medium
and industrial/commercial
segment. Systems for
renewables like solar, biomass
and natural heat complete the
comprehensive product range.

Compact yet powerful
The compact design with low build height
makes the Vitoradial 300-T an ideal choice
when modernising heating centres. It is
supplied as a unit with the downstream
flue gas/water heat exchanger and the
Vitoflame 100 pressure-jet burner.
Triplex pipes for 2.5-times larger
heating surface
The multi-layered convection heating surfaces
of the Vitoradial 300-T are comprised of
telescopically arranged steel pipes pressed
into each other for ideal heat transfer.
The internal tube with its folded linear
ribs provides a heating surface 2.5-times
larger than that of smooth pipes. The heat
throughput is metered by the dierent
intervals between the press points so that the
back area of the triplex tubes, through which
slightly less hot combustion gases circulate,
transfers less heat to the boiler water. This
way, the surface temperature remains above
the dew point, the formation of condensate
is counteracted and corrosion damage is
prevented.
Utilising condensing technology with the
Inox-Radial heat exchanger
The downstream Inox-Radial heat exchanger
makes it feasible to utilise highly ecient
condensing technology, even with
medium-sized boiler system, such as the
Vitoradial 300-T. The seasonal eciency
[to DIN] is raised by 8 % to 97 % (Hs).
This principle ensures that combustion and
condensation occur in physically separate
locations, so the combustion gases condense
in a location which is free of deposits. In
practice, this means standard service intervals
for cleaning the combustion chamber and low
maintenance costs.
The new Vitoradial 300-T is available up to
335 kW output. The stainless steel Inox-
Radial heat exchanger is highly ecient. This
prevents the danger of corrosion through
acidic condensate.

dierent burners
The compact Vitoplex 200 steel boiler is
now also available from 90 to 1950 kW.
Over the entire output range, this three-
pass boiler oers the right conditions for
an environmentally responsible and clean
combustion. A wide range of burners can be
easily adapted to be used with this boiler. The
Vitoplex 200 is a genuine three-pass boiler
with low combustion chamber loading and,
therefore, clean combustion with particularly
low nitrogen oxide emissions.
Optimum combustion and low emissions
Factory-fitted with the two-stage
Vitoflame 100 pressure-jet oil burner up to
270 kW and the two stage Vitoflame 100
pressure-jet gas burner up to 200 kW,

Older buildings, in particular, can give rise
to diculties when introducing new boilers
because they suer from tight spaces. With
the Vitorond 200 sectional cast iron boiler,
sections can be brought into the boiler
room individually, where they can be easily
assembled in situ with a compression tool.
Eutectoplex heating surfaces for high
operational reliability and a long service
life
The cast sections of Vitorond 200 boilers are
made from special eutectic cast iron with
homogeneous structure. The fine design of
the graphite fins and the high level of material
purity of the low phosphorous special cast
iron increase its elasticity. Material, shape
and geometry of the cast sections provide
even cooling during production. This prevents
structural stresses right from the start.
Result: high operational reliability and a long
service life.
Three-pass boiler with low emissions
At the end of the combustion chamber, the
hot gases flow forward through four hot
gas flues arranged symmetrically around
the combustion chamber and enter the four
collectors of the third hot gas flue via the
front section. At the back of the boiler, the
four cooled hot gas flues are channelled via
the flue gas connection to the chimney. The

permanent self-cleaning eect, thus ensuring
a permanently high utilisation of condensing
technology, resulting in a longer service life
whilst reducing maintenance eort.
The Vitocrossal 300 boiler is available
with a factory-fitted MatriX radiant burner
or prepared for fitting Elco or Weishaupt
pressure-jet gas burners.
The highly eective heat transfer and the
high condensation rate enable seasonal

Rising fuel costs are of particular concern
to users of medium and industrial boiler
systems. The utilisation of condensing
technology has a particularly high impact on
the operating costs of medium and industrial
boiler systems. Energy-conscious condensing
technology has, therefore, increased in
significance.
Separate flue gas/water heat exchangers are
used for larger systems or when retrofitting
existing systems. There, flue gases are further
cooled so that water vapour condenses. The
yielded latent condensation heat and the low
flue gas temperatures provide a significant
increase in eciency.
Vitotrans 300
The Vitotrans 300 is a flue gas/water heat
exchanger for the utilisation of condensing
technology with boilers from 80 to 6600 kW.
With downstream installation this can raise
the seasonal eciency of the boiler by up to
12 % for natural gas and up to 7 % for fuel oil.
Utilising condensing technology with medium and industrial/commercial boilers
through downstream installation of heat exchangers promotes lower operating costs.

System technology Solar thermal and
photovoltaics
All medium and industrial/commercial boilers can be combined with suitable solar
technology. In such cases, the free solar energy provides the DHW heating.
Solar thermal – free solar energy
Particularly on commercial buildings, the wide
expanse of flat roofs oers an ideal base for
the installation of collector arrays.
The principle is quite simple
Of course, the utilisation of solar energy
requires innovative technology and lots
of experience: Solar thermal systems
"harvest" solar energy in the flat-plate or tube
collectors. In these, a heat transfer medium
is heated by the insolation and routed into a
DHW cylinder. There, the heat is transferred
to the potable water to be heated via internal
A new heating system and a solar thermal
system simply go hand in hand. There are
good reasons for this. In the summer, the
majority of the energy demand for DHW
heating can be covered by solar collectors.
Subject to system sizing, the system can also
provide central heating backup.
Calculated over the year, 60 % of energy can
be saved on DHW heating alone. After all,
solar energy is free, and daylight is converted
into heat by the collector even when the sun
is not shining directly onto the roof.
Vacuum tube collectors can be
installed anywhere, and in new
build also make for an attractive
architectural feature.

indirect coils, alternatively to the heating
circuit via heat exchangers. Thereafter, the
cooled liquid is returned to the collector, and
the cycle begins again. If the insolation is
insucient, e.g. in winter, the boiler provides
reheating.
The Vitosol range oers solar collectors for
every aspiration and every budget. Installation
on the roof or wall opens up a variety of
design options.
Flat-plate and tube collectors
The Vitosol 200-F flat-plate collector stands
out because of its high quality, lasting
operational reliability and high eciency. With
its extremely translucent anti-reflex glass and
highly selectively coated copper absorber,
the high performance Vitosol 300-F flat-plate
collector utilises the intensive solar radiation
particularly eciently.
The Vitosol 200-T vacuum tube collector
is characterised by its particularly eective
thermal insulation and high eciency resulting
from its Sol-titanium coating. It can be
installed anywhere.
The Vitosol 300-T meets the highest
demands. This top quality, high-performance
collector is designed around the heat pipe
principle.
Generate your own power with Vitovolt
The Vitovolt 200 and Vitovolt 100 photovoltaic
modules generate electrical energy right in
the solar cell, which is fed straight into the
public grid via an inverter.

DHW cylindersSystem technology
The demand for hot water is completely
dierent in every household. One factor is
the number of draw-o points, and another is
the use of hot water. For example, in hotels
or large residential complexes, particularly in
the morning plenty of hot water for showers
needs to be available.
After all, the DHW cylinder should also
provide sucient water if hot water is
drawn from dierent points of the building
simultaneously.
The Vitocell DHW cylinders fulfil these
requirements in every respect and can also
meet every aspiration where equipment levels
are concerned. In all instances, the installation
of a solar thermal system is recommended to
save energy and heat the water without cost.
With the Vitocell DHW cylinders, Viessmann oers the convenient solution for the supply
of domestic hot water.

The right DHW cylinder for every demand
The Vitocell range of cylinders meet all
requirements for a suitable DHW cylinder. For
commercial applications, floorstanding DHW
cylinders are the first choice.
Hygienic DHW provision
The quality of the inner surface of the
DHW cylinder is crucial to providing DHW
hygienically. For this reason, Viessmann relies
on two high quality materials: Ceraprotect
enamel coating for safe, lasting protection
against corrosion for the Vitocell 100 range,
and stainless steel for the Vitocell 300 range
for the highest of hygiene standards.
The indirect coils inside Vitocell DHW
cylinders reach right down to the cylinder
floor. This enables them to heat the entire
water content, making them very economical.

Vitodesk – software competence from one source
Vitodesk is the complete software support package for heating contractors, design
engineers and architects. All programs support automatic data exchange.
Vitodesk 100
Vitodesk 100 is the free data service from
Viessmann. It enables users to select
Viessmann products for design/engineering
and tendering.
Vitodesk 200
Vitodesk 200 is tailored to the planning and
sizing of smaller and medium-sized building
projects. It is divided into three areas, i.e. RES
(renewable energy systems), sanitary/heating
and air conditioning.
The ESOP 4.0 module, which is part of this
software package, is designed for calculations
around solar thermal systems. This program
is based on the computation module of
T-SOL that is recognised by bodies oering
subsidies. The weather data sets of numerous
European countries are supplied as standard
or can be added on at a later date.
Vitodesk 300
Viessmann developed its own OEM version
from the industry standard AutoCAD
program. In addition to the main functions
of the full version, this software oers many
additional assistants that make engineering
and presentation even more convenient and
ecient.
Complex heating centres can be designed
much more eciently and precisely with this
3-D program than with conventional software
tools. The 3-D boiler room engineering
program can check in advance whether the
system can fit into the existing boiler room
with all required components. It means
engineering errors can be eliminated during
the design phase.
The program assistants not only support
the creation of the pipework layout, but
also oer tools for the true-to-scale design
of distributors and containers. All required
sectional depictions and views, plus
designations, can be produced on the design
and are updated automatically when changes
are made.
The product management runs unobtrusively
in the background. This enables a detailed
output of the parts lists, even including
a cutting list. The provision of rendered
diagrams enables systems to be clearly
and professionally presented, giving a clear
advantage prior to orders being placed.
Clever software supports design
engineers and trade experts alike in
realising their projects.

Individual solutions with ecient systems
Now that the Viessmann Group includes ESS,
Köb, KWT and Mawera amongst its brands,
the company covers the complete breadth
of powerful heating systems. These include
biomass boilers, heat pumps and combined
heat and power units (CHP). All systems
share the use of renewables that protect finite
resources. The CHP can be operated with
natural gas as well as with biogas.
For many commercial and industrial sectors,
the operation of a biomass power station
with heat generation is an obvious choice,
for example, in the wood processing
industry, in landscape gardening and in
the forestry sector. Here, suitable boilers
can predominantly cover the base load. In
addition, oil or gas boilers can cover peak
loads and thereby safeguard a continuously
ecient provision as and when required.
ESS CHP units for operation with natural gas
or biogas not only generate heat but also
power that can be consumed on site or fed
into the public grid.
Wood heating systems up to 1250 kW from
Köb combust wood of any kind: pellets,
sawdust, wood chips and mixed wood. These
are particularly suitable for commercial and
industrial applications.
Mawera supplies wood combustion systems
up to 13,000 kW. Commercial energy
suppliers increasingly bank on biomass as
fuel. It is obtained from crisis-proof regions
and makes a crucial contribution to preserving
fossil fuels, not least through sustainability
and CO2-neutrality.
Heat pumps from KWT are specifically
adapted to each individual case. Subject to the
challenges facing the operator, water/water,
brine/water or air/water heat pumps can be
supplied.
The comprehensive Viessmann product range for all fuel types and application areas
oers top technology and sets new standards.

City of Tomorrow, Malmö, Sweden
Futureproof heating technology for
all requirements
Energy consumption worldwide has doubled
since 1970 and will triple by 2030. The
result: The fossil fuels, oil and gas, are
dwindling, energy prices are on the rise and
excessive CO2 emissions continue to aect
our environment. Energy eciency is a must if
we want our future to be secure.
In almost every industrial nation, supplying
heat to residential and commercial buildings
accounts for the largest share of energy
consumption – consequently it also oers the
greatest savings potential. Advanced ecient
heating systems from Viessmann are in use
around the world, not only in many private
households, but also in numerous major
international projects, where they make a
sizeable contribution to the ecient use of
energy resources.
In these projects, Viessmann again and
