"Efficiency Plus" – a case
study
1
Structural change in the heating sector
is both a challenge and an opportunity
All forecasts at the beginning
of 2007 pointed towards the
continuous growth of the market
in Germany. The ISH, the flagship
international exhibition for the
industry held in Frankfurt in early
March, reflected this optimism.
However, 2007 turned out to be
completely different. The heating
sector in Germany contracted
by a quarter. There are many
reasons for this: As a result of
the increase in value added tax
and the fact that the subsidy on
the purchase of a home was
abolished at the turn of the year,
many investment decisions were
brought forward, leaving new
build to tumble by as much as
50% in 2007.
In addition, politicians and the media generally strongly influenced
the opinion that we need to “get
away from oil and gas”. This
has created long-term uncertainty
among many system users. It is
also possible that the extremely
mild weather last winter has contributed to the considerable fall
in the number of heating systems
being modernised.
These trends affect not only
Germany: similar movement can
be seen in other European countries too, such as in France, for
example. The inertia in our sector
not only worsens the prevailing
modernisation backlog – it is also
thwarting the global warming
objectives of our politicians and,
in particular, those of the German
government.
2
The heating equipment
sector offers considerable
potential
The federal government has not
only adopted the EU’s 20/20/20
formula with a commitment
to save 20% of fossil fuel and
increase the proportion of
renewable energy to 20%: It even
wants to cut CO2 emissions by
40% rather than the original 20%.
The government wants to project
itself as an international pioneer
in the fight against global warming. During the national energy
summit and many associated
discussions, it was successfully
made clear to politicians that
the heating sector can make an
enormous contribution and this
issue must be addressed accordingly. Accounting for almost 40 %
of our total energy consumption,
i.e. the largest share, it consequently offers tremendous
potential. Only slightly over 10 %
of German heating systems are
state-of-the-art. If the remainder
were converted using the technology currently available, such
modernisation would result in
energy savings of 32% in the
heating sector. That in turn would
reduce overall energy consumption in Germany by 12 %.
Uncertainty among
system users is slowing
down growth
Theoretically our industry is well
placed to reap the benefits of a
flourishing modernisation business. The trends towards highly
energy efficient technologies
such as condensing technology
and boilers operating with
renewables have initiated a
structural change.
Viessmann is well prepared
for structural change
With its comprehensive range
for all fuels and output ranges,
Viessmann took early steps to
prepare for this challenge, and
recognises opportunities for new
business.
However, an attractive range that
is appropriate for market requirements is, on its own, no guarantee of success. This is why three
years ago in 2005 we started the
"Efficiency Plus" project at our
head office in Allendorf (Eder),
investing a total of 220 million.
The aim of "Efficiency Plus"
is to boost our international
competitiveness to safeguard
jobs at our high wage German
base.
The largest part of this project
is the complete rebuild of our
production facilities at the main
factory. With this, Viessmann is
putting in place the elements
required to cope with structural
change in the heating sector
by upgrading our production facilities.
The "factory fit for the 21st
century" is being built in Allendorf
by applying the flexible and
efficient structures and processes
of Japanese lean production
approach.
We have also implemented the
political twin strategy of greater
efficiency and substitution by
adopting an energy concept that
is designed to meet the needs of
the future. At the same time the
energy efficiency of our plant,
in both terms of generation and
consumption, was given a sustained boost. For the substitution
of oil and gas with renewables,
we have primarily opted for
biomass and are producing a
considerable proportion of our
fuel requirements through our
own short-rotation coppices.
"Efficiency Plus" saves 40%
of fossil fuel
Our pilot project, which also acts
as a model for other systems, is
attempting to prove that the energy and climate policy objectives
set for 2020 can be achieved with
technology that is on the market
today. We are saving 40 % of
fossil fuel and are reducing CO2
emissions by a third.
New academy to cover
an increasing demand for
advanced training
The growing significance of new
technologies using more energy
efficient and renewable forms of
energy requires more highly qualified personnel. This applies to
both our partners in the market
place and to our own employees.
This is why we have invested
€20 million in building the new

company and are highly experienced in the international world
of business.
Decentralisation of the
company
Viessmann Academy with an innovative energy centre attached,
which is used for training and
demonstration purposes under
real-life operating conditions.
From as far back as the 1960s it
has been a Viessmann tradition
to provide advanced training for
trade partners and Viessmann
employees alike. Today there
are information centres and
hospitality suites in Allendorf and
in Berlin, as well as seminar and
training facilities in all 120 sales
offices worldwide, all operating
under the overall direction of
the Viessmann Academy. Overall,
each year 70 000 industry
specialists attend advanced
training events at the Viessmann
Academy.
Information centre conveys
the values and expertise
that embody the company’s
philosophy
The new Viessmann information
centre comprises the Academy
and energy centre, as well as the
"Galeria" that houses an exhibition
illustrating the essence of our
brand, and the "Via Temporis"
museum. One benefit is the
close proximity to the factory
enabling guided tours through the
manufacturing plant.
This means that our guests not
only receive technical information
during their visits to our plant,
but they also gain first-hand
experience of the values and expertise that embody the essence
of our company’s philosophy.
Official opening of the
new information centre
At the new Viessmann information centre we can give our visitors a live demonstration which
explains how by making selective
investments every home owner,
company and public body can
combat global warming and to
reduce their own energy costs.
Our energy concept can
certainly be considered as a
model for others to follow.
We present our project as a genuine object lesson for all political
representatives and decisionmakers from the world of busi-
ness. Of course, this project is
also of interest to our trade partners as it both supports them in
their consulting role and helps to
back up decisions with pertinent
facts.
Strengthening our
management
Developing new business areas
and new markets – including
acquisition and mergers – has
prompted us to reinforce our
management. We have therefore
transferred management to an
administrative board. As chairman, I shall in future devote more
time to the strategic development
of our business. The delegates of
the administrative board, headed
by the group’s CEO Peter Schenk,
will be in charge of day-to-day
operations. In his last post, Peter
Schenk was director of the GEA
Group AG, where he was responsible for the corporation’s core
business with sales around
€4000 million. Joachim Janssen,
CFO, is in charge of our finance
and controlling activities; he was
previously also at GEA. Both
gentlemen bring with them the
professionalism of a large
In the coming year we are going
to decentralise the Allendorf
site so that we can respond
even more quickly to changing
underlying conditions. Above all,
we are going to increase business
responsibility within the company,
even at our head office, by transferring individual divisions such
as sales for the German market
and production in Allendorf to
independent companies.
Our aim is to be a strong partner
on whom our customers will be
able to continue to rely.
Together we have excellent opportunities to generate movement
in the market and achieve real
growth. Let’s make the most of
those opportunities. Apart from
anything, our shared success will
advance the struggle against
global warming and help to attain
our energy-political objectives.
I would like to wish all customers,
business partners, friends of the
company and employees a peaceful and happy Christmas. Also,
all good wishes for a healthy and
successful year in 2008.
Yours, Dr. Martin Viessmann

"iF product design award"
for Vitoladens 300-C
Not one but two Viessmann
products have now received the
"iF product design award 2008"
for their excellent design: These
are the new Vitoladens 300-C oil
fired condensing boiler (see also
the article on page 22) and the
ET 35 thermostatic head from
the Vitoset range. A total of 1002
participants from 35 countries
entered 2771 products in their
quest to win this prestigious
award. The assessment was
made by an international jury.
The iF awards are among the
most important design accolades
worldwide. The iF Industrie Forum
Design e.V. is one of the oldest
design centres in Europe and was
founded in 1953 by Deutsche
Messe AG, the Bundesverband
der Deutschen Industrie (BDI) and
a number of companies with an
interest in design. Right from the
start the concept that design is a
vital part of the value chain determined the profile of the Industrie
Forum as a competent intermediary between design and industry.
The new Vitoladens 300-C oil fired
condensing boiler received the
prestigious "iF product design
award 2008".
Austria Solar quality mark
for Viessmann
In October, Viessmann was
awarded the Austria Solar
quality mark for the outstanding
quality of its solar products.
Dr. Gilbert Frizberg, Vice President
of the Steiermark Chamber of
Commerce, presented the award
to Peter Huber, Managing Director
of Viessmann Austria at the
Ökosan07 conference.
As Frizberg said during his
speech when he made the presentation: "Quality marks give
people confidence that the technology will be with us for a long
4
time and that it will work".
Frizberg also emphasised the
importance of efficient and high
quality solar technology for
achieving objectives linked to
global warming.
The quality mark is confirmation
by an independent commission
that the manufacturer satisfies
stringent quality criteria. This
applies to all components of
the solar heating system as well
as aspects such as technical
support.

Saarland follows joint declaration
on oil condensing technology
The Saarland Ministry of the Environment and trade associations
for plumbing, heating and ventilation contractors, flue gas inspectors and the petroleum sector
signed a joint declaration on 19
November concerning the introduction of highly efficient oil
condensing technology and lowsulphur fuel oil. Targeted PR and
an extension of training and qualification activities are important
components of the package of
measures set out in the declaration. In addition to this, comprehensive geographical coverage
of supplies of low-sulphur fuel oil
is going to be developed. Similar
declarations have already been
signed in North Rhine Westphalia,
Bavaria and Thuringia.
Measures to increase energy
efficiency play an important role
as part of an all-embracing policy
to combat global warming.
Consequently, greater use of oil
condensing technology is a significant component of energy policy.
When it comes to heating, oil
fired condensing technology will
save approximately 10% of energy compared to the use of oil
fired low temperature boilers.
Carbon dioxide emissions fall by
roughly the same order of magnitude. At up to 30% the reduction
in carbon dioxide is even greater
when it comes to older boilers.
According to a press release
from the IWO, the institute for
efficient oil heating, it is obvious
that consumers need further information and advice in this area.
Wider use of oil condensing
technology is very important for
effective action against climate
change.
Future of gas heating technology
The "Gas heating" forum on future
trends, held in Essen on 9 and
10 October, addressed the current
market situation and the changing
underlying conditions. Futureorientated perspectives for action
and technical developments were
presented at the conference,
which was held in the GWI Institute for gas heating and organised
in cooperation with the DVGW
(German technical and scientific
association for gas and water),
the BDH (German industry association for domestic, power and
environmental engineering) and
figawa (the German association
of gas and water applications).
Dr. Stefan Hoffmann, Viessmann's
head of research and development, gave a presentation to approx. 100 delegates concerning
the current development work
undertaken by the heating equipment sector regarding micro CHP
and gas heat pumps. For instance, gas heat pumps have an advantage over electrically operated
compression heat pumps because
they only require 1/3 of the ambient energy, enabling more costeffective heat sources to be used.
However, the first products
using these technologies will
not be market-ready before 2009.
Even then, it will initially only
be possible to use these units for
selective applications.
Viessmann heat pumps
lead the way
A survey by the German Sanitation, Heating and Air Conditioning
Association (ZVSHK) involving
around 1000 contractors specialising in plumbing, heating and ventilation showed that Viessmann
was the most popular manufacturer of heat pumps. Viessmann
received 22.2% of the votes and
took top position ahead of Stiebel
Eltron (15.6%), Dimplex (11.1%),
Buderus and Vaillant (each with
7.6%). Other manufacturers
followed – Alpha Innotec (5.0%),
Junkers/Bosch (4.0%), Nibe and
Siemens (each with 3.8%), Waterkotte (3.0%), Bartl and Ochsner
(each with 2.8%). Incidentally, one
of the split air-conditioning market
leaders Daikin received 0.8% of
the votes, which put it in 16th
position out of a total of 36 manufacturers/suppliers mentioned.
Another result of the survey was
that just under a third of the plum-

heat pumps in 2006: On average
it was four systems per company.

and split air-conditioning units
that operate like heat pumps were

Pellet boilers comply
with dust limits
The BDH (German industry association for domestic, power and
environmental engineering) has
established that modern wood
burning and pellet boilers already
comply with the more stringent
emissions criteria envisaged by
the amendment to the Federal
Emissions Law(1. BImSchV).
The systematic development of
heat sources has made considerable progress in the past few
years. This applies both in respect
to reducing emissions and in
relation to improving efficiency.
Advanced wood burning and
pellet boilers need less fuel because they burn more efficiently,
are clean and do not require
additional filters. This makes
CO2-free heating using wood an
economically viable and ecologically sensible choice, even
bearing in mind the more stringent
requirements of future environmental legislation.
Advanced wood burning and pellet
boilers (here, the Vitolig 300) already comply with the more stringent
emissions thresholds envisaged.

Official opening of the academy, energy centre and exhibition centre:
Viessmann’s new information centre
On 28 November 2007 Viessmann’s new information centre
was officially opened at an event
attended by Dr. Alois Rhiel, the
Minister of the Economy in the
State of Hesse, many of Viessmann’s trade partners and guests
from the world of business
and politics. The information
centre houses the academy,
including the heating centre, the
"Galeria" exhibition showcasing
Viessmann’s technical expertise
and the "Via Temporis" museum.
The Viessmann Academy
The trend prompted by the structural change towards particularly
energy efficient technologies and
renewable forms of energy has
increased the need for training
Numerous business associates and
guests from industry and politics
attended the opening ceremony.

among our employees and our
trade partners. A total of €20 million has been invested in Viessmann’s new academy with its innovative energy centre, to make it
easier to convey knowledge about
these new technologies. The
modern training facilities cover
some 6000 m2 of usable space.
The top floor provides space for
five seminar rooms and seven
training rooms equipped with the
latest media technology. A variable wall partition system also
allows space to be organised
flexibly to suit requirements. The
training rooms are equipped with
Viessmann’s entire product range
in ‘live’ conditions for physical
product training sessions. Apart
from condensing boilers for oil
and gas, the centre also includes
plenty of renewable energy
systems such as solar, biomass
and geothermal heat.
The ground floor holds a foyer,
two information points and a
restaurant for up to 300 guests.
It also includes space for the
new sales floor of the Viessmann
The energy centre supplying the
entire plant is linked to the new
academy building.
Company news
After the ceremony the guests
were given a tour of the new building.
The key is handed over: Right on
schedule, architect Thomas
Frauenkron handed over an extra
large key card to Dr. Viessmann.
The full range of Viessmann’s
comprehensive product range is
available in the training suite under
‘live’ conditions.
Every year a total of 70000 specialists attend advanced training
events at the Viessmann Academy, which not only sees itself as
an educational institution but also
as a meeting place for our industry, contractors and academics
alike.
However, if politicians and the
media spread the message "get
away from oil and gas", yet do
not provide investors with any
guidance or proof on how they
are supposed to do this, then it
is hardly surprising that system
users prefer to sit on their hands
rather than take action.
technology can have the same
energy saving effect as thermal
insulation work. If a condensing
boiler is used, it becomes even
more efficient if the thermostat
is turned down at a later date
when additional thermal insulation
is installed.
Framework conditions
crucial for reaching targets
Another example is the tendency
to equate energy efficiency with
insulating the building envelope.
Furthermore it is claimed that
the amount of heat required
can be reduced through building
insulation and then, if there is
any doubt, consumers could "get
away with" a smaller and cheaper
heat source. This is simply not
the case. A considerably smaller
investment in advanced system
Sportshop. Ranging from fashionable and practical sportswear to
high-quality porcelain, this shop
has plenty of attractive goods on
offer.
Quality and qualification are
closely linked. For this reason
advanced training has been a
long Viessmann tradition; courses
for commercial partners and
employees have been an enduring
part of company policy since the
1960s. Today the overall concept
of the Viessmann Academy
includes information centres with
hospitality suites – at the company head office at Allendorf (Eder)
and at the production site in
Berlin – as well as rooms for
theoretical and practical training
in all sales offices worldwide.
Broad based training
program
The Viessmann Academy, which
is directed at those who specialise
in plumbing, heating and ventilation, design engineers, architects,
energy consultants, developers,
flue gas inspectors and the
company’s own employees,
offers a comprehensive range
of courses. Not only technical
courses are available: Subjects
such as the engineering and
design of heating systems as
well as marketing courses are
also covered.
There is general agreement that
energy needs to be saved
and CO2 emissions must fall
considerably to prevent further
global warming.
Debates about saving energy by
replacing conventional light
bulbs with energy-saving bulbs
or not leaving HiFi equipment and
televisions on standby must be
seen in a similar context. The populist nature of such arguments
become clear once you know that
lighting in the average household
costs €95 per annum and devices
on standby in domestic homes
account for the princely sum of
€17.

The right balance between
compulsion and choice
The renewable energy obligation
is moving in the wrong direction.
To use as much renewable energy as possible cannot be the objective. Instead the aim should be
to use as little energy as possible
but at the same time reduce CO2
emissions. This is why the state
should not set inflexible targets
on how to save energy. Instead,
investors should be allowed to
choose whether they achieve this
through the use of condensing
technology, heat pumps or boilers
burning biomass.
The use of condensing technology
is not only a more substantial
lever but it also a much more
efficient alternative and, in most
cases, also the first step towards
the installation of a dual-mode
system with solar backup.
Subsidy policies require
the right standards
In this respect, the combined
incentives agreed in October as
part of the incentives program for
the market is at least a step in
the right direction. As a result,
a condensing bonus is paid if an
old boiler is replaced with a
condensing boiler when, at
the same time, a solar heating
system is installed.
In stark contrast is the failed
policy on photovoltaic. The German government wants to use
the EEG (Renewables Energies
Act) to raise the contribution
made by photovoltaic to energy
generation to 2% by 2020. To
achieve this, feed-in tariffs are
paid which will total €28 000 million by 2020.

products on the ground floor.

This will not achieve the set target. We need a balanced energy
mix because renewables will
not, in their totality, be sufficient.
Even in the long term – and that
means by 2050 – will renewables
only be able to cover a good half
of the overall energy required.
It is very important for all
mandatory statutory targets and
incentives programs to be
measured according to their
contribution to increasing energy
efficiency and displacing CO2
emissions, and the costs incurred
to avoid such emissions.
Innovative energy centre
Whereas discussions are still
taking place – for example, at the
United Nations Climate Change
Conference on Bali – on how to
reach the objectives required to
prevent global warming, Viessmann has already taken action.

the office areas. For a full report
on the "Efficiency Plus" program,
see pages 10/11.
Energy park
A model scheme on how to grow
and process biomass has been
established in the open area
adjacent to the energy centre.
The area is divided into several
plots so that visitors are practically presented with time-lapse
images that allow them to understand the various growth phases
of short-rotation coppices and
how they are turned into useable
energy.
This is where visitors are given
information about the company
and the energy-political framework

"Galeria" with an exhibition
encapsulating the brand
The "Galeria" that is attached to
the new Viessmann Academy,
presents a visual image of the
values that encapsulate the
core brand factors to which the
company is committed. For instance, it illustrates how Viessmann demonstrates its responsibilities to society as a whole and
to the environment every day and
how, in the face of increasingly
tough international competition,
the company produces high
quality goods at prices that
can hold their own in the market
place.

40 percent less oil and gas, a third less CO2
"Efficiency Plus" – Viessmann's comprehensive range
to combat global warming
Fossil fuel consumption down
40%, CO2 emissions cut by a
third – Viessmann is showcasing
a model to combat global warming
at its own company's Allendorf
site as part of its "Efficiency Plus"
project. Viessmann is setting a
signal with "Efficiency Plus"
that tomorrow's objectives in
respect of global warming can
be achieved today through
systematic actions and technology
that is on the market today. Over
a three-year period, the company
has invested around €220 million
in its Allendorf site. This investment includes the erection of a
new energy centre and the academy, as well as a reorganisation of
the production processes.
Viessmann has been an environmental pioneer for a long time.
In 2000, Viessmann was one of
the founding members of the
"Environmental Alliance" in the
Federal State of Hesse. It was
also the first heating equipment
supplier in Europe to be awarded
the EMAS certificate (Eco-Management and Audit Scheme), a
standardised EU-wide system for
environmental management and
environmental inspection in
businesses. Viessmann signed a
cooperation agreement in Allendorf with the German Association
for Nature Conservation (NABU),
thus reinforcing its solid track
record on environmental issues.
This is how Dr. Martin Viessmann
explained the company's strategy
to journalists: "We want to
demonstrate in our own company
what every business and every
home can do to combat global
warming through targeted innovation and how our own energy
expenditure can be reduced.
Climate change is no natural
event beyond our influence: Even
ambitious targets in respect of
global warming can be achieved".
The energy centre of the
future – with technologies
to protect the climate
The holistic "Efficiency Plus"
concept to combat climate
change covers energy generation,
consumption and also production
methods in the Allendorf plant
that will not harm the climate.
As a result of these efforts, the
amount of fossil fuels consumed
have been cut by 40% compared
to previous levels and CO2
emissions have been reduced
by a third.
Greater energy efficiency
Around 50% of all savings have
been achieved by increasing
energy efficiency. On the
consumption side these include:
Energy-optimised production
processes
Heat recovery from test beds
Thermal insulation of
buildings and
Doors that open and close
especially quickly.
On the generation side, i.e. in the
new energy centre, practically all
advanced energy technologies are
utilised:
Highly efficient condensing
systems for oil and gas
Biomass boilers and
Combined heat and power
plants.
Short rotation coppice with
poplar saplings, around six months
after planting.
10
Substitution with
renewables
The second half of all savings is
achieved by replacing fossil fuels
with renewables:
Bio-oil and biogas replace
fuel oil and natural gas
A solar heating system backs
up the heating system and
powers absorption refrigeration
equipment for climate control
in the building
Heat pumps utilise ambient
heat
A photovoltaic system
Woodchip burning boiler with
a Stirling generator and
Substitute electricity from
conventional power plants
with electricity generated
from renewables using a
turbine (ORC process).
It is intended that savings of
fossil fuels will increase to 50%
through the use of further
technical innovations relating
to renewables. Consequently,
condensing systems and a gas
fired CHP plant will in future be
fuelled by biogas produced on
site at Allendorf. The following
systems are also envisaged:
Fuel cell energy systems
Gas operated heat pumps and
Use of solar heat in
manufacturing processes.
Identifying efficiency
potentials in industrial
companies
This is how Viessmann demonstrated at their own production
facilities how the political dual
approach of boosting efficiency
and substitution can be implemented at this moment. Whilst
also illustrating the enormous
efficiency potential that can be
realised within a very short time
in an industrial company using
technologies that are already
available on the market. Yet again,
with this model, Viessmann highlights its role as an industry leader
in innovation and technology.
Heat sources for all types of fuel are
installed in the Viessmann energy
centre: Condensing systems for oil
and gas, a gas fired CHP plant, biomass boiler for generating heat and
power, heat pumps, solar heating
systems for heating and cooling, and
photovoltaic panels.

Partnership for innovation and environmental protection
Viessmann and NABU seal cooperation agreement
On 27 November 2007, the
German Association for Nature
Conservation (NABU) and Viessmann sealed a cooperation
agreement at the company's
headquarters in Allendorf to
cooperate in the common fight
against global warming. This
agreement covers support from
Viessmann for NABU's projects
on nature conservation and technical advice from NABU for the
company's environmental projects. Together with the environmental organisation, Viessmann
will establish a working party to
discuss issues relating to climate
policy.

Viessmann is recognised as an
environmental pioneer in German
industry: It became the third
company in Europe and the first
in the heating equipment sector
to obtain certification according to
the EMAS environmental management system (eco audit). As a
founder member of the environmental alliance in the State of
Hessen, Viessmann also received
a "Glanzlicht Hessen" (Beacon for
Hessen) award in 2004. Dr. Martin
Viessmann received the award for
environmentally aware company
management, which is awarded
by the ASU association of independent entrepreneurs, no less
than four times in recognition of
the company's comprehensive
voluntary and effective measures
for environmental protection. All
Viessmann products stand out
through their high efficiency and
low emissions. As an example,
the MatriX radiant burner was
awarded the European environment prize (EBEAFI).
NABU is the oldest nature conservation organisation in Germany
and one of the most prestigious
environmental associations. In
addition, the parties to the agreement share a clear commitment
to climate protection: One of
the claims in the preamble to
the framework agreement clearly
spells it out: "Sustainable re
sponses to social challenges
require an open dialogue".

comprehensive package of measures
to combat climate change. From left:

Development of renewables
German Ministry for the Environment presents
draft legislation on the use of renewables (EEWärmeG)
On 5 December 2007, the federal
cabinet agreed a comprehensive
package of measures to combat
climate change. According to
Sigmar Gabriel, the German
Minister for the Environment,
this emphasises Germany's
pioneering role in tackling global
warming.
The package consists of 14 laws
and regulations and seven further
measures which, for technical
reasons, cannot be agreed before
next May. The German Ministry
for the Environment is confident
this will enable Germany to get
very close to its target of reducing carbon dioxide emissions
by 40% by 2020, compared to the
base year 1990.
The measures include amendments to a number of existing
laws. For instance, this has an
effect on legislation on combined
heat and power, the German
energy industry act (EnWG), the
renewable energies act (EEG) and
the energy savings order (EnEV).
These measures envisage,
amongst others, a tightening of
12
building regulations relating to
energy by an average of 30%.
Apart from the transport sector,
the energy sector will also be affected. Considerable importance
is attached to the heating sector
too. New draft legislation in the
form of the law on the use of renewables for heating (EEWärmeG)
is being presented expressly to
promote renewables for heating.
It is intended that this will boost
the share of renewables in heat
generation to 14% by 2020. To
achieve this, the draft heating
energy bill will focus on three
pillars:
The obligation to use
renewables
Firstly, there is an obligation.
Owners planning new build must
use renewables for heating.
This obligation affects all owners,
regardless of whether they are
private individuals, public bodies
or businesses. All forms of renewables can be used and in any
combination – solid biomass,
geothermal power, solar power or
ambient heat. Bio-oil applies if
it is used in conjunction with
condensing technology. Biogas is
only applicable if it is used in CHP
systems. Property owners can
also apply other measures to
meet their obligations such as
fitting additional insulation to their
property, purchasing heat from
district heating systems or using
heat generated by CHP systems.
Local and district heating
Finally, there are the heating
networks. The heating energy bill
makes it easier to extend local or
district heating systems. Local
authorities will be able to specify
connection to and use of heating
systems of this kind for reasons
that include climate protection.
Minimum requirements
Incentive schemes
Secondly, there are financial
incentives. To make the financial
burden of upgrading existing
heating systems with those that
use renewables socially acceptable and to create effective investment incentives, it is intended –
subject to budget constraints –
to increase the amount available
for grants each year (market incentives scheme) from €130 million in 2005 to a maximum of
€350 million in 2008, rising to
€500 million from 2009 onwards.
Special minimum specifications
are to apply to individual types of
fuel. For example, solar collectors
must provide an area of 0.04 m2
per square metre of living space,
(in other words, for every 100 m2
of living space there must be
4 m2 of collector). Where solid
biomass, geothermal heat or
ambient heat are chosen, these
must cover the majority of the
prevailing heating demand, i.e. in
excess of 50%. Here ecological
and technical requirements must
be met – for example, a certain
performance factor where heat
pumps are used.

Dr. Hans Viessmann's 90th birthday
Remembering a major entrepreneur
Dr. Hans Viessmann would have
celebrated his 90th birthday on
15 November. Born in 1917 in Hof
an der Saale, Dr. Hans Viessmann
was one of the major entrepreneurs in post-war Germany. An
exceptionally gifted technician
and engineer, he conveyed an
irrepressibly inventive spirit
co-joined with good judgement
on what was technically feasible
as well as what was required to
satisfy the needs of the market
and those of trade partners. He
was a visionary with the courage
to take entrepreneurial risks and
had a gift for taking the right decisions, even in difficult situations.
Dr. Hans Viessmann initiated the
triumphant march of the steel
boiler that took the place of cast
iron boilers which had dominated
the market right into the 1950s.
Thus started the dynamic development of the company. This
continued seamlessly into the
1960s with new and convenient
systems for domestic hot water,
innovative special oil and gas fired
boilers designed to save energy
and protect the environment,
plus control systems especially
developed for these boilers.
A new start for the business
in Allendorf
Dr. Hans Viessmann had the skill
to continue to strengthen his business by introducing innovative
products during the energy crises
of the 1970s. As a result, he
successfully introduced a host of
especially environmentally friendly
and energy efficient products
during that period that were just
what the market wanted and,
even today, are considered to be
technical milestones.
His business career began in
1947 when he took over the production facilities that had evolved
from a workshop established by
his father, Johann Viessmann, at
Hof in Upper Franconia in 1937,
which was relocated to Allendorf
(Eder) in the German Federal
State of Hesse. At that time, the
company employed 35.
Capturing the leading
positions in the market
Successful handover
to his successor,
Dr. Martin Viessmann
At the end of 1991, Dr. Hans
Viessmann retired from the
heating sector. He handed over
the management to his son,
Dr. Martin Viessmann, who had
been working for the business
since 1979.
Dr. Hans Viessmann was one
of the major German entrepreneurs.
Afterwards, Dr. Hans Viessmann
continued to devote his life to
his plants in Bavaria. Following
the death of his wife Martha, he
spent the last years of his life in
Hof, the town where he was
born, where he continued to
work on technical projects, his
enthusiasm undimmed.
What started in 1947 among
the ruins and destruction left behind by WWII was developed
by the passionate businessman,
Dr. Hans Viessmann, into the
Viessmann Group, which now
accounts for sales of €1400 million and counts more than 7400
employees. Dr. Hans Viessmann
died on 30 March 2002 at the age
of 84.
Social commitment and a
bond with the region
Dr. Hans Viessmann was not only
a committed businessman: He
was also a patron of the arts,
sciences and culture. Particularly
prominent was his social and cultural commitment: He dedicated
himself to the preservation of
art and cultural objects for the
benefit of later generations.
Dr. Hans Viessmann gives a
lecture during the higher education
program held in Battenberg.
Here Viessmann became the
largest employer, with its
three factories in Allendorf and
Battenberg. He also demonstrated his social concerns by establishing a total of 14 subsidiary
plants primarily in structurally
weak areas. He was convinced
that it was a better social policy
to bring work to people rather
than the other way round. As a
result, apart from the factories
in Allendorf, factories were established in Hof (Saale) – the town
of his birth – and in Faulquemont
(Alsace Lorraine) and Mittenwalde
(Brandenburg).
He was also passionate about
encouraging training and further
education. He realised that progress and quality could only be
secured through life-long learning.
Consequently, he established the
Viessmann Academy, which today
trains 70 000 heating specialists
every year.
Dr. Hans Viessmann felt a particularly strong bond to the region
of North Hesse and the Rural
District of Waldeck-Frankenberg.

New impetus for town and
region
The original plan was to extend
the visitor’s suite in Battenberg to
prepare for the future of training
activities at the new Viessmann
Academy at the company’s head
office in Allendorf (see the report
on pages 6 to 9). However, after
the company was offered the
Hotel Sonne in the historical old
town of Frankenberg, it was decided to buy the hotel, renovate it
thoroughly and use it in addition
to the visitor’s suite in Battenberg
to accommodate visitors.
Not only business guests and
holidaymakers benefit from
"Die Sonne Frankenberg" hotel,
local residents profit too.

Viessmann 2007:
A review of the year
For our business, the ISH 2007
was the first big highlight of the
year. Viessmann presented its
comprehensive range in Frankfurt,
covering all types of fuel and output ranges along an "energy bolt".
This illustrated the range structure, leaving visitors in no doubt
that Viessmann has the products
to meet future challenges in respect of energy and climate policy.
The most prominent visitor to the
exhibition stand was Environment
Minister Sigmar Gabriel, who
was welcomed by Dr. Martin
Viessmann as he walked round
the exhibition after opening the
event.
Numerous victories for the
Viessmann Team
The 2006/2007 winter sport season again saw numerous wins
for athletes in the Viessmann
team. They notched up wins in
the biathlon world championships
in Antholz as well as eight gold,
three silver and four bronze
medals in World Cup events in
Nordic combination and toboggan
competitions.
"Private art!" initiative
As in the past few years, in 2007
Viessmann again took part in the
initiative promoted by the Economics Ministry and the Ministry of
Arts and Sciences of the Federal
State of Hesse to exhibit art held
by private organisations. Together
with 25 other companies from
Hesse, Viessmann participated
by opening its "Art and heating"
exhibition to the public.
Official opening of
information centre
28 November 2007 saw the
official opening of the new
information centre that houses
the new Viessmann Academy,
the "Galeria" and the company
museum "Via Temporis". The
exhibition areas of the academy
and Galeria provide a visual demonstration of the core themes
shaping the company’s brand
as well as the current range of
products. Also, the company’s
"Via Temporis" museum, dedicated to the life’s work of Dr. Hans
Viessmann, was completely
remodelled and now traces the
development of the company
over the decades.
The new energy centre has been
built adjacent to the academy
building and is an important part
of the "Efficiency Plus" project to
safeguard the future of the site.
Through "Efficiency Plus" Viessmann is, firstly, working more
efficiently through lean structures
and processes and, secondly,
giving a sustained boost to
energy efficiency in terms of generation and consumption. As a
result, 40% of fossil energy have
been saved and CO2 emissions
were reduced by one third.
Viessmann has demonstrated,
using currently available technology, that the German government’s
targets set for 2020 to combat
climate change are not only attainable but can even be exceeded
right now.
Awards
In 2007 Viessmann was again
voted "Trade partner No. 1" in a
survey of several thousand heating contractors. This accolade
has now been awarded to Viessmann nine times in succession.
Vitoladens 300-C and Vitoligno
300-P were awarded the "red dot

Viessmann Vitomax commercial and industrial boilers
Convincing systems solutions for efficient hot water
and steam generation
With a comprehensive product
range covering all fuel types and
with an output range from 1.5 kW
to 20 MW, Viessmann offers a
system suitable solution for
any heating application that is
precisely matched to the specific
requirement. Biomass systems
from Köb and Mawera as well
as oil and gas fired Vitomax
commercial and industrial boilers
are available, if a particularly high
output is required. The Vitomax
range comprises hot water and
steam boilers for any application
in industry, commerce and heating plants. Individual customer
requirements can also be correctly matched using Vitomax boilers
with tailor-made designs.
Utilisation of condensing
technology up to 6.6 MW
Vitomax 100-LW, 200-LW, 200-WS
and 300-LT are low pressure hot
water boilers with output up to
20 MW and permissible operating
pressures up to 10 bar. Hot water
boilers can be combined with a
Vitotrans 300 flue gas/water heat
exchanger. This means that condensing boilers can be operated
in a particularly energy efficient
mode up to 6.6 MW. The Vitomax
200-HW high pressure hot water
boiler is suitable for higher operating pressures of up to 25 bar
and an output up to 16.2 MW.
Welded smoke tube: To comply with
particular national specifications
and customer requirements, welded
seams are examined using ultrasound and X-ray procedures before
the goods leave the factory.

Steam is used in laundries, industrial kitchens and hospitals for
very different purposes. The
Vitomax 200-LS covers the low
pressure requirement (up to a
maximum operating pressure of
1 bar) in the output range up to
five tonnes of steam per hour.
Steam volumes of up to 25 tonnes
per hour and pressures of up
to 25 bar are covered by the
Vitomax 200-HS high pressure
steam boiler. If required, this
boiler is also available with an
integrated economiser (flue gas/
water heat exchanger for preheating feed water) that achieves
efficiency ratings in excess of
95% for cost-effective steam
generation.

Vitomax commercial and
industrial boilers for special
applications
Power plants and many industrial
processes produce what is
termed waste heat, which was
frequently vented into the environment. The Vitomax 200-RW
and 200-RS heat recovery boilers
make use of this heat to generate
hot water or steam and thus
help to save valuable energy and
reduce CO2 emissions.
Special applications require tailormade system solutions. Vitomax
commercial and industrial boilers
are also designed and produced
to order, i.e. to specifically meet
customer and special national
requirements. An example of this
is the Vitomax 300, with an output of 20 MW, which is used in
the currently largest burner test
bed in the world at the Weishaupt
research station in Schwendi. The
boiler is nearly ten metres long,
has a diameter of four metres and
has a dry weight of an impressive
50 tonnes. Its combustion
chamber is almost two metres
in diameter and is high enough
to accommodate an upright adult.
Nowhere else is there such a
large boiler as this Vitomax 300
used for test runs and type
approval tests for Weishaupt
burners that operate with natural
gas, fuel oil and special fuels.
The boiler design is the
reason for top quality
Irrespective of whether they are
standard boilers or specials, all
Vitomax commercial and industrial
boilers are characterised by high
efficiency, exceptional operational
reliability and a long service life.
Highly effective thermal insulation
combined with combustion
chambers without firebrick linings
reduce radiation losses to a
minimum. The three-pass design
(excluding Vitomax 100-LW) with
low combustion chamber loading,
water-cooled reversing chambers
and burner apertures ensure
clean combustion of oil and gas.
Wide water galleries and a high
water volume ensure that heat
is transferred efficiently and the
system operates reliably during
the entire period of use.
Along the lines of the Viessmann
motto: "Quality must be created,
not inspected." Even whilst the
Vitomax boilers are built, appropriate safeguards are put in place
to maintain top quality. Advanced
manufacturing facilities such as
welding robots as well as laser
and plasma cutting equipment
provide maximum precision. To
be absolutely sure that the high
quality standards the company
has set itself are attained,
additional quality checks are introduced at the end of important
manufacturing stages. A pressure
test using at least 1.8 times the
operating pressure is carried out
on Vitomax boilers at the end
of the manufacturing process.
To comply with particular national
specifications and customer
requirements, welded seams are
also examined using ultrasound
and X-ray procedures.
Coordinated system design
for Vitomax boilers
All systems need to work
together without any problems
if a Vitomax boiler system is to
operate efficiently and reliably.
Regardless of whether heat
exchangers, chemical or thermal
water treatment systems, pump
assemblies or safety equipment
are employed – the system
design provided by Viessmann is

Viessmann Vitoladens 300-C is
the most compact freestanding
oil fired condensing boiler. The
picture shows a Vitocell 300-H DHW
cylinder, below.
Vitoladens 300-C:
Compact oil fired condensing boiler for modernisation
and new build
Over the next few decades, oil
and natural gas will continue to
account for a considerable proportion of our energy supplies. Even
optimistic estimates work on the
basis that by 2050, no more than
50% of our energy demand can
be covered by renewables. This
makes it even more important to
treat our increasingly precious
stocks of fossil fuel with ever
greater care and to use them in
a way that has a minimal effect
on the environment.
If generation of heat is required,
innovative condensing technology
is among the most efficient
solutions and therefore one of
the kindest to the environment.
For that reason, Viessmann's
comprehensive product range
includes freestanding and wall
mounted condensing systems
for oil and gas with output ranging from 3.8 kW to 6.6 MW.
Apart from the tried and tested
Vitoladens 300-W and 300-T
condensing boilers and the
Vitoladens 333-F with integral
DHW cylinder, a new particularly
compact boiler is being introduced for operation with oil – the
Vitoladens 300-C.
Quick and easy installation
The tried-and-tested duplex biferral composite heating surface and
the Inox-Radial heat exchanger
are combined in one unit in the
Vitoladens 300-C. This results in
the Vitoladens 300-C having the
most compact dimensions of all
freestanding oil fired condensing
boilers on the market.
Hydraulic connections and the
ventilation air and flue connections are on the top of the boiler.
This enables a space-saving installation that is almost flush with
the wall. The Vitoladens 300-C is
therefore particularly suitable for
modernisation projects where the
space available is limited.
Compact dimensions make
handling and installation of the
Vitoladens 300-C much easier.
This oil fired condensing boiler is
fully pre-assembled, so it can be
commissioned within a very
short time.
Hydraulic connections and ventilation air and flue connections are
on the top of the boiler. This allows
installation flush with the wall.
22
Future-proof through bio-oil
preparation
The two-stage compact blue
flame burner adapts the output
(12.9 to 28.9 kW) to the actual
heat demand. It is suitable for
open and balanced flue operation
and, thanks to an integral silencer,
it operates very quietly. Low
flue gas temperatures and high
utilisation of condensation gains
make the Vitoladens 300-C particularly efficient (standard efficiency: Up to 98% [Hs] / 104% [Hi]).
The Vitoladens 300-C can operate
trouble-free, efficiently and reliably with all types of fuel oil
available on the market. Also, the
new Vitoladens 300-C is suitable
for use with bio-oil obtained from
sustainable managed crops. This
ensures that the Vitoladens 300-C
will provide reliable and efficient
heating in the future too.

Vitodens 222-W:
Wall mounted gas fired compact condensing boiler
with integral primary cylinder
Vitodens wall mounted and compact boilers make up a seamless
range of highly efficient gas fired
condensing boilers for modernisation and new build, for detached
houses, apartments on single
floors and large apartment blocks.
The new Vitodens 222-W extends
the Viessmann range of gas fired
compact condensing boilers
that are fully equipped with DHW
cylinders into the wall mounted
sector.
Primary cylinder for
convenient DHW delivery
The Vitodens 222-W is a space
saving, wall mounted gas fired
condensing boiler to satisfy
high DHW demands. An integral
46 litre stainless steel primary
cylinder supplies up to 20 litres
of hot water per minute (for peak
periods). It offers the same level
of DHW convenience as a separate internally heated DHW cylinder
with a capacity of 150 litres.
DHW is available almost immediately in the required amounts and
at a constant temperature, even
if DHW is drawn from several
draw-off points simultaneously.
Fits in nearly any recess
Apart from the primary cylinder,
nearly all vital system components such as heating water and
DHW expansion vessels, pumps
and safety valves are integrated
and fully fitted. Despite this, the
system has a dry weight of only
63 kg (6.5 to 26.0 kW) and adheres to the standard kitchen unit
width of 600 mm. Consequently,
the Vitodens 222-W fits in nearly
every recess and is very easy to
handle. All components can be
accessed from the front, making
clearances for servicing at the
side superfluous.
An installation aid incorporated
in the boiler secures all connections on a panel, thus saving installation time. As a wall mounted
boiler the Vitodens 222-W also
has the advantage that it can
be fitted in new build before the
screed is applied.
Efficient utilisation of gas
condensing technology
The tried and tested stainless
steel Inox-Radial heat exchanger
combined with the modulating cylinder burner, recently developed
by Viessmann and incorporating
stainless steel MatriX gauze and
offering a modulation range of
1:4, provides particularly efficient
and environmentally responsible
combustion. The Vitodens 222-W
(4.8 to 35.0 kW) offers a standard
efficiency of up to 98% (with reference to condensing value Hs)
or up to 109% (with reference to
calorific value Hi).
The Vitodens 222-W heat cell
consists of the stainless steel
Inox-Radial heat exchanger, the
modulating MatriX cylinder burner
and the automatic Lambda Pro
Control combustion controller.
Like every Vitodens gas fired condensing boiler from Viessmann,
the Vitodens 222-W is also equipped with the innovative Lambda
Pro Control combustion controller.
This means that it is no longer
‘necessary to adjust the boilers
‘to the type of gas concerned.
The Lambda Pro Control identifies
different gas qualities, fluctuations in air pressure, changes in
pressure drop and adjusts the
‘boiler accordingly. Even when
‘mixing biogas with natural gas,
the combustion remains stable
whilst maintaining high efficiency
levels.
The newly developed MatriX
cylinder burner has a modulation
range of 1:4. The integral Lambda
Pro Control combustion controller
adjusts combustion automatically
to changing gas types.

Romania's largest heating system:
Innovative Viessmann technology for the Dacia plant
July 2007 saw the completion
of the largest heating system in
Romania at the Dacia vehicle
manufacturing plant. Two
Viessmann steam boilers and
two hot water boilers with a
total of 70 MW supply heat to
fifty buildings in the plant.
The works cover a total area of
2.9 square kilometres (equivalent
to around 380 football pitches). It
employs 12000 in fifty buildings
totalling 623000 m2. Without the
slightest exaggeration, the task of
installing a new heating system
there can be described as a major
challenge. Special attention was
paid to installing a system that
provided maximum efficiency.
24
Innovative Viessmann
heating technology
Those in charge decided in favour
of Viessmann's innovative heating
technology: Now two Vitomax
200-HS steam boilers that together produce up to 20 tonnes of
steam per hour, are installed in
the radically modernised heating
centre. The steam is required in
the paint shop. Vitomax 200-HS
is an oil/gas fired high pressure
steam boiler with a permissible
operating pressure of up to
25 bar.
Two Vitomax 200-HW hot
water boilers, each delivering
up to 16 MW, are installed
in the heating centre. The
Vitomax 200-HW is particularly
suitable for use in large industrial
complexes. It operates with flow
temperatures in excess of 120 °C
and pressures up to 25 bar.
Meeting specific customer
requirements
the three-pass design and the
water-cooled reversing chambers
ensure clean combustion of oil
and gas with all commonly used
burner systems. Safety and
control features can be added to
the scope of delivery as optional
extras to meet specific national
requirements. Large doors to
allow the boiler to be cleaned
and a large number of service
apertures make it very convenient
to service. In addition, many years
of experience in the construction
of commercial and industrial boilers guarantee high quality and
ensure that they operate reliably
over a long service life.
Because of their design and
equipment, commercial and industrial Vitomax boilers are most
suitable to fulfil individual customer requirements. For instance,
In total, the system at the Dacia
plant delivers 70 megawatts. This
makes it the largest heating plant
installed in Romania to date. At
Dacia they are expecting that this
All boilers in Dacia's heating centre are suitable for two different
fuel types, i.e. both can be operated with gas and heavy fuel oil.
To ensure that the viscous heavy
fuel oil can be atomised as finely
as possible into the combustion
chambers, it is first heated up to
a temperature of 160 °C to reduce its viscosity.
Practical applications
Ambitious country in south eastern Europe
The Dacia plant near Pitesti covers
2.9 square kilometres in total.
Romania is one of the most
ambitious countries in south
eastern Europe. Since the start
of the millennium, the economy has been growing by an
average of 5% per annum.
This positive development can
primarily be attributed to industrial activity, traditionally an important sector, the construction
boom, agriculture and the
service sector. Another part of
the economy that is experiencing strong growth is tourism.
As a result, Romania has set
itself ambitious targets since
it joined the European Union in
2007: It is envisaged that the
euro will replace the Leu, the
national currency, by 2012.
However, several obstacles still
have to be overcome before
then – for example, further
economic reforms must be
implemented and tight controls
need to be exerted on expenditure.
Important share of
economic growth
Dacia is one of the companies
that have made a crucial contribution to economic growth in
Romania. The Dacia plant was
established near the town of
Pitesti in 1968. Pitesti, which is
about 130 kilometres from
the capital Bucharest, is in the
Romanian region of Walachia,
which – roughly translated –
means "far off" or "isolated".
Originally an independent marque,
Dacia primarily used to produce
small trucks and commercial
vehicles for the Romanian market.
After the fall of the Ceausescu
regime, the number of vehicles
produced at Dacia fell sharply and
the company was forced to seek
a technical partner. In the 1990s
they entered into an informal
cooperation agreement with
Peugeot but it was not to last.
In 1999 Dacia became a subsidiary of the Renault Group; in
2004 the company passed into
full ownership of the French
motor manufacturer. Since
then, Renault has produced
the Dacia Logan at the plant.
In contrast to earlier Dacia
models, the Logan is not only
intended for the Romanian or
eastern European market: It
is also being sold in western
Europe.

investment will cut energy
consumption by 17% per annum
and reduce harmful emissions
by around 20000 tonnes a year.
In view of the size of the project
and the huge economic significance of the company, it is not surprising that there was considerable interest among the public
when the plant was officially
opened on 24 July 2007. Even
national television came to file a
report.
Two Viessmann Vitomax 200-HS
steam boilers and two
Vitomax 200-HW hot water boilers
were installed in the heating centre.

Modernising historic administrative buildings
Viessmann Vitoplex boilers heat
the German Ministry of Research
Even though Berlin became the
capital of Germany at the end
of the 1990s, some ministries
still have an official office in
Bonn. The Federal Ministry of
Education and Research (known
as BMBF for short) is one of
these ministries. At moment
the BMBF building, which is
over thirty years old, is being
modernised to save energy and
improve its CO2 footprint.
Viessmann supplied the heat
sources for this endeavour.
26
The Federal Ministry of Education
and Research building is part of
the government district in
Bonn-Bad Godesberg that was
conceived in the 1960s and was
supposed to accommodate all
ministries in seven cross-shaped
high-rise buildings. Two buildings
were erected in the Heinemannstrasse in 1974. These are called
the "Kreuzbauten" because
their footprints are shaped like
crosses. At the time, the buildings were considered to be two
of the most advanced buildings in
Bonn. The design was audacious;
visible concrete was considered
to be the ultimate material to
select for both inside and out;
it became a virtue to put the functions of the building on show –
for example, the load-bearing
systems of the concrete piers and
bases. However, the architecture
that was celebrated by experts
as being of the future, was not
universally popular to say the
least. The barrage of public
criticism prevented the remaining
five cross-shaped buildings from
being built. Today the majority
of the approximately 1000 employees of the BMBF work in
the "Kreuzbauten" in Bonn, which
are now listed buildings.
Adapted to current
requirements
On 22 December 2006 the last
tarpaulins and scaffolding were
removed from the first of the
"Kreuzbau" buildings. The comprehensive modernisation work had
begun eighteen months before.
The building – both inside and
out – was renovated to meet current needs regarding technology,
energy usage and users' requirements. Now, even at first glance,
the "Kreuzbau" looks like a much
more friendly building. The
reddish brown of the facade that
gave the building a rather sinister
look, has been replaced by a
pale grey. The first of three construction phases has now been
completed under the overall
control of the Federal Office for
Building and Regional Planning.
The second and third phases
entail the modernisation of the
second "Kreuzbau" and three
other buildings on the site.
Heating centre 65 m up
Since the autumn of 2006, the
new heating centre has been
operating in the first "Kreuzbau"
building. Two gas fired mediumsized Vitoplex 300 boilers with
an output of 1750 and 1400 kW
respectively, both with Vitotrans
300 flue gas heat exchangers to
utilise condensing technology and
Practical applications
At the moment the building
occupied by the Federal Ministry
of Education and Research is undergoing thorough modernisation. The
heating centre has already been
modernised – Viessmann delivered
the new boilers.
Elco burners, replaced the two
old boilers, each of which delivered 2900 kW. These had been in
service since the building was
originally constructed. The heating
centre is located 65 m above
ground level on the top floor. Consequently a crane was required
to lift the boilers into position.
This was only possible from one
single point so the crane had to
be positioned very accurately in
order to be able to unload the
boilers and system components
in the installation opening.
It was the turn of the second
"Kreuzbau" on 30 July 2007: The
boilers, two gas fired mediumsized Vitoplex 100 boilers each
with an output of 1120 kW and
Vitotrans flue gas heat exchangers, were supplied. As was the
case with the first building, the
boilers had to be heaved into
place using a crane weighing
several tonnes. To carry out this
operation, the surrounding streets
first had to be closed and the
trees on the side of the road cut
back so that the huge crane could
be moved into position. The Bonn
"General-Anzeiger" newspaper
wrote: "It was a lot of effort for a
boiler, but with the best will in
the world, it would not have fitted
through the door." The system
went into service at the start of
the 2007 heating season.
struction noise as far as possible
or obstacles caused by the building work: It was a major concern
that the extensive security at
the ministry was maintained. The
task was also made more difficult
by limited access and facilities
at the building site. Some clever
logistics were required: In view
of the limited space available,
very careful planning and management was required with regard
to the delivery of the various
components, the deployment of
personnel and the disposal of
parts that had been replaced.
From 2008 the users – the BMBF
and the Federal Railway Authority
– will be able to resume their
work without disruption. It is
planned that other institutions
such as the German Institute for
Adult Education will be linked into
this project, work planned by the
BMBF around the "Kreuzbauten"
to promote Bonn as a centre of
scientific excellence.

How is a graphics symbol created?
"Efficiency Plus" – a case study
A book by a prominent art
dealer and gallery owner bore
the title: "Art does not come
from skill". He is right because,
in the age of digital computer
design, the graphic artist no
longer needs the manual
skills required in the past.
A good graphic design evolves in
the mind. A good visual solution
in graphic form for communications purposes stands out through
its ease of understanding, simplicity and timelessness. In an
ideal situation, you can recognise
the style of the graphic artist. For
this, a piece of work must have
its own individual signature.
In "Efficiency Plus" case study,
the initial sketched ideas with the
"E" and the plus symbol display
a geometric coherence. A further
stage of development is the "E"
with the word "Plus" and the plus
symbol in one.
Initial sketched ideas that depict the
subject and give pointers as to how
it can be developed further.
The solution is Viessmann’s
graphic design for the core brand
value "Efficiency" enhanced by
the mathematical plus symbol.
In other words, it is a typically
Viessmann graphic, displaying
a very concise form and a high
recognition factor.
Here are a few criteria for
assessing good brands and symbols: Ability to attract attention,
memorability, orientation,
signal effect, information value,
recognition factor, durability, independence, scope for integration,
variability, suitability for size
reduction and, naturally, the
aesthetic element that makes it
appealing.
It is interesting how the word "Plus"
is combined here semantically with
the plus symbol.
The solution is a combination of
the "Plus symbol" with the existing
"Efficiency" graphic from the series
of company principles.
