National energy summit –
Opportunity for the heating industry?
Despite its current weakness,
there is still a considerable
amount of potential in the
German heating market that the
industry needs to realise. More
than two million boilers that are
older than 25 years are still being
used in German homes. These are
technically obsolete and waste oil
and/or gas.
Considerable amount of
energy saving potential in
the heating sector
The potential savings are
tremendous. Heat generation in
buildings constitutes the biggest
proportion of energy consumption
in Germany at almost 40%. In
comparison, transport consumes
about 30%. However, due to the
drastic increase in energy prices
and conflicting information
concerning supply reliability, many
operators of systems that require
modernisation have been deterred
and are waiting to see what
happens.
The amount of money that is
being spent on modernisation has
therefore fallen well below the
required level in recent years.
Only 60% of the annual amount
of modernisation that is required
is taking place. Instead of 830
000 systems, just 500 000
systems are being modernised.
This means that 40% of energywasting systems are still being
used.
As well as steep price increases,
the global energy situation is
characterised by the limited
availability of oil and gas, rapidly
increasing demand from countries
such as China and India, and
dependence on imports from a
small number of emerging
2
regions, some of which are
politically and economically
unstable, which is why political
action is required.
At the energy summit on
3.4.2006, the German
government gave the go-ahead
for a “National Energy Plan”,
which should:
– ensure a reliable supply,
– protect the climate,
– provide a high level of efficiency
– and price stability.
A well considered balance of
different energy types is also
required.
In order to achieve these goals as
quickly as possible, the policy is
aimed at gradually reducing the
maximum permitted building
energy demand in accordance
with the Energy Savings Order
(EnEV) and adding energy
analyses and renovation
recommendations to the energy
demand certificate that is
prescribed for new buildings by
the EnEV [Germany].
Use of efficient technology
saves 25% in the short term
The use of efficient system
technology, combined with solar
energy if possible, can
significantly reduce oil and gas
consumption. Oil and gas must
be replaced with more use of
renewables in the medium to long
term.
Even if just the above-mentioned
two million obsolete systems
were modernised in the near
future, the energy demand in the
overall building sector could be
reduced by 25% within a short
time. This constitutes 10% of all
energy that is consumed in
Germany. This is why system
users using outdated heat
sources would be well advised to
replace them with modern,
energy-efficient technology as
soon as possible.
Oil/gas condensing
technology – economical
and future-proof
The cheapest alternative to
reducing oil and gas consumption
is to replace obsolete boilers with
modern oil/gas condensing
technology. The investment of
approx. 4000 Euros that is
required to do this will pay for
itself in five years.
Where the primarily concern is to
become independent of oil and
gas and economy is less
important, it is advisable to use a
heat pump that utilises heat from
the environment or a solid fuel
boiler such as a pellet boiler.
However, these products are
considerably more expensive than
oil or gas condensing systems. A
pellet boiler costs approx. 10 000
Euros, and a heat pump plus bore
hole can cost more than 20 000
Euros. At 10 to 15 years, the
amortisation time is therefore two
to three times greater than that of
condensing systems, in spite of
existing subsidies.
Irrespective of the increasing
importance of renewables,
slogans like “away from oil and
gas” are misleading. They
generate uncertainty and prevent
the necessary steps from being
taken, causing too much energy
to be consumed unnecessarily.
50% benefit from changing
the energy mix
In the long term a further 50% of
current gas and oil consumption
can be saved by changing the
energy mix in favour of
renewables. This depends on
whether the alternative energy
sources are economical
alternatives and are available in
sufficient quantities, continuously,
all year round.
Sustainable raw materials
offer good opportunities
Sustainable raw materials such as
wood, or gaseous or liquid fuels
that are acquired from biomass,
provide a good alternative for heat
generation. They are available all
year round and can be mixed with
(and sometimes replace) fossil oil
or gas as soon as they can be
provided in to an acceptable
standard and in the correct form.
However, a considerable amount
of research and development
work is required before this can
be achieved.
Editorial
The existing subsidy programs
must therefore be examined with
the aim of aligning them with the
energy saving level of the
respective measures
independently of the technology
and the energy source. The main
focus should on supporting
research rather than applications.
To summarise, it can be said that
the heating sector and heating in
buildings can make a significant
contribution to the success of the
“National Energy Plan”. It is
important for outdated heating
systems to be modernised with
efficient technology and to
gradually replace oil and gas with
biogenetic fuels.
To the industry, this means a
change towards highly-efficient
heat sources which are able to
use an increasing proportion of
renewables. Successfully realising
this structural change is both a
challenge and an opportunity.
Comprehensive supplier for
all energy sources
Be it oil/gas condensing
technology, solar heating
systems, pellet boilers or heat
pumps, the complete Viessmann
range covers all applications with
innovative top products and the
relevant comprehensive range of
system peripherals with perfectly
matched components.
The trade is also provided with
effective support within the scope
of the comprehensive Viessmann
range of services, from technical
training to specific marketing
measures and sales financing.
The company can draw on
decades of experience with
renewables. We were already
utilising biomass, heat from the
environment and solar energy for
heat generation back in the
1970’s. Even then, the Viessmann
product range included solid fuel
boilers, heat pumps and solar
collectors.
future and continue to put our
faith in profitable growth using
innovation and quality.
We think that there are good
prospects for 2006 and beyond,
both in the international markets
and in Germany. Firstly, the
economic mood has improved
again, and secondly, the
implementation of energy-related
and environment-related
European Directives will revitalise
the market. More stimuli for the
increased use of energy-efficient
technology can be expected from
the energy plan 2007.
The energy summit on 3rd April 2006
in Berlin forms the prelude to the
formation of a “National Energy
Plan” that the government wishes
to develop with the business sector.
Together with you, our market
partners, we will use the
opportunity that has presented
itself to help the best possible
technology to make a
breakthrough on a wide front. We
stand by our responsibility of
saving energy and protecting the
environment.

The Portikus
Art Gallery boiler
Exhibits from the trade fairs in the
Czech Republic, Poland and Slovakia
The new Portikus state art gallery
in Frankfurt am Main successfully
combines the old with the new.
The name refers to the surviving
part of the municipal library of
1825 that was largely destroyed
during World War II. During the
course of the modernisation and
extension of the old bridge,
different bridge structures were
used to restore this historic site.

impressed by its energy
efficiency, its environmental
friendliness and the future
capability of the Vitodens 343,
that it was an easy choice to
make.
The Portikus is an internationally
renowned exhibition hall for
contemporary art, where artists
from all over the world are able to
try out new ideas. The gallery is
intended to be a “showcase for

Ministerial visit to
Viessmann trade fair stand
The Viessmann Group presented
its domestic fuel cell heating
centre on a shared stand at the
Hanover Trade Fair from 24th to
28th April. As well as many
international visitors, three
ministers were also welcomed to
the stand. The Federal Minister
for Transport, Construction and
Urban Development, Wolfgang
Tiefensee, the Hessen Minister
for Economy and Regional
development, Dr. Alois Riehl, and
the Hessen Minister for the
Environment, Rural Areas and
Consumer Protection, Wilhelm
Dietzel, acquainted themselves
with modern heating technology
and were especially interested in
fuel cell technology.
Alois Riehl pointed out the
urgency of looking for cheaper
alternatives to conventional power
4
generation. Federal Minister for
Transport, Mr Tiefensee, was
particularly interested in the
possibility of feeding biogas from
recycled raw materials into the
natural gas network.
Viessmann is working intensively
on the fuel cell. The domestic fuel
cell energy centre is being
developed in-house together with
partners from industry and the
Centre for Solar Energy and
Hydrogen Research in Ulm. The
system is currently in the
prototype phase. Field trials are
due to take place this year,
demonstration systems with
market partners will follow from
2007 to 2009, and the market
launch of the Viessmann domestic
energy centre will take place in
2010.
Viessmann was awarded a
second gold medal at AquaTherm, namely for the best
realised project in the
“Renewables” sector. The award
was given for the advanced
heating project designed for the
village of Stràzny in the Bohemian
Forest nature reserve. Twelve
Vitocal heat pumps, with a total
output of approx. 300 kilowatts,
were installed in the heating
centre, and a solar heating
system with Vitosol 300 solar
collectors with a total area of
about 100 square metres.
The conversion to the new heat
sources (the buildings in Stràzny
were previously heated by coal)
has not just reduced emissions
considerably, but energy costs
have also fallen dramatically.
Medals were also awarded for
outstanding products at the
“Instalacje” trade fair in Posen,
Poland. Two Viessmann products,
namely the Vitodens 300 gas
condensing boiler and the Vitocal
343 Compact Energy Tower, were
bestowed with the “IMP Gold
Medal”, which is Poland’s oldest
and most prestigious trade fair
award. No other manufacturer has
ever succeeded in winning two
gold medals.
The trade fair stand also won an
award, namely the “Acantus
Aureus” award. This plaque is

an exemplary way.
Viessmann also received awards
at the Recionenergia trade fair in
Bratislava, Slovakia, and at the
“Beogradski Sajam” in Belgrade.
The Vitocrossal 200 gas fired
condensing boiler was awarded
the “Golden Plaque” as the best

Solar energy also supported in 2006
Solar heating systems are
becoming increasingly popular
because of the high energy
prices. The subsidies from the
federal marketing program
[Germany] that have not been
granted since October 2005 are
now available again.
The German government
subsidises small solar energy
systems for heating DHW to the
tune of 84 Euros per square
metre of collector area. For a
large system for central heating
backup, homeowners receive 108
Euros per square metre of
collector area. In order to take
advantage of the higher subsidy
there must be a minimum
collector area of ten square
metres for flat-plate collectors
and eight square metres for
vacuum tube collectors. A special,
adequately dimensioned heating
buffer is also required.
People who are interested in solar
heating systems should make
their applications to the Federal
Ministry for Economy and Export
Control (Bafa) as soon as

possible. The solar heating
system must not be installed until
the subsidy has been confirmed.
The Federal Ministry also
approves the applications in order
of receipt. Anyone who applies
early can therefore install the
system sooner and claim the
subsidy. If a new heating system
without solar energy is installed,
empty ducts can be routed to the
roof in order to make it easier to
retrofit a solar heating system
later.

The heating sector as an opportunity for
a lasting energy policy
The global energy situation has
shown both consumers and
politicians that action is required
concerning the efficient use of
energy, which applies to transport
and heat generation alike.
The heating sector offers good
opportunities to a lasting energy
policy.
Almost 40% of energy
consumption in Germany is used
for heat generation. In
comparison, transport only
consumes about 30%.
It is also interesting and
extremely important to note that
private households are
responsible for two-thirds of the
comparatively high proportion of
energy used for heating. The
energy price trend
is of the utmost relevance to all
consumers. This is because it has
a direct influence on household
budgets. There are two ways of
reducing the consumption of
fossil-fuel energy: Firstly by
increasing efficiency, and
secondly by replacing it with
renewables. Consumption could
be reduced by 25% in the short
term using simple methods of
improving efficiency.
In relation to the overall energy
consumption in Germany this
would be 10%, i.e. the potential
is tremendous.
The first step in exploiting this
potential would have to be aimed
at modernising the oldest and
thereforethe least energy-efficient
houses
and their heating systems, i.e.
bringing them up to the state-ofthe-art. This includes reducing the
level of heating that is required
using suitable insulating methods,
particularly by replacing obsolete
heating equipment with modern,
efficient technology such as oil or
gas condensing equipment.
Wherever possible, these
systems should be supplemented
with solar heating systems for
heating hot water.
Significantly more can be
achieved in the medium to long
term. Oil and gas consumption
can be reduced by an additional
50% by using new technologies
that utilise the renewables. Some
of the technology that is required
is already available (such as heat
pumps and pellet boilers), others
still need to be developed further.
It would not be impossible to
reduce the amount of oil and gas
that is consumed for heating by
approx. 75%.
13% of all heating systems in
Germany (i.e. 2 million) are more
than 25 years old. From a
technical point of view these
systems are completely out-ofdate and waste energy.
Irrespective of its condition, a
heating system should be
replaced no later than after 18
years to keep up with technical
developments. This means that
800 000 systems required
modernisation every year.
However, only 500 000 systems
were replaced last year.
This has an extremely detrimental
effect on energy efficiency and
energy costs for consumers.
Modernising old systems is
therefore, the order of the day.
Almost 40% of the energy consumption in Germany
is expended on heat

Replacing old boilers with modern
condensing equipment is the
most cost-effective alternative.
Anyone to whom independence
from oil and gas is more
important than saving money
would be well advised to have a
heat pump or pellet boiler
installed, depending on the
system-specific conditions.
In any case it is advisable to add a
solar heating system during the
course of modernising the
heating system to provide hot
water.
The solar heating system can
cover the entire water heating
demand with free solar energy in
summer. The coverage rate is
60% over the course of an entire
year. The government needs to
come up with some general
conditions that encourage
modernisation if it is to tap the
existing savings potential in the
short term.
The currently applicable Energy
Savings Order (EnEV) fails to
achieve this, since the conditions
thereof essentially relate to new
buildings and are less relevant to
existing buildings. But this is
where the potential lies.
A good example that could be
used as a guideline can be found
in the Netherlands, where the
energy efficiency requirements
for buildings were stipulated ten
years ago. Right from the
beginning, dynamics were in
place that gradually made the
requirements stricter in a two-

year cycle. This does not just
apply to heating, but all domestic
energy consumers.
The targets are clearly defined,
but no measures for achieving
them are described.
This ensures that consumers pay
attention to using the most
economical technology that is
available in their own interest and
on their own responsibility. From
a financial point of view, this
means a high level of target
achievement at minimum cost.
When we are talking about
substituting fossil fuels with
renewables, we must also have
an awareness of the extent to
which this is available.
Hydroelectric power is already
being exploited to a considerable
extent. A significant proportion of
wind power and biomass energy
is already utilised. However, only
a minimal amount of solar energy
and geothermal energy is
exploited.
Here is a case for pressing ahead
with potential exploitation using
the best technology that is
available or yet to be developed.
More intensive research work is
required. This is why the subsidy
method that has been used to
date needs to be revised.
Targeting subsidies to specific
technologies can only tap into a
limited amount of potential.
It is obvious that there is no easy
way of achieving a new energy
framework. Many different
methods will have to be tried out
simultaneously in order to
produce a balanced combination
of energy sources. It is
particularly important for these
energy sources to be utilised as
efficiently and economically as
possible, which also applies to
renewables.
Gas and oil will be substituted in
several stages. Biogenetic fuels
such as rapeseed oil and bio-gas
are already available. However,
existing oil and gas fired boilers
have to be modified to use these
fuels. Furthermore, there are also
problems to be solved with
regard to storage and supply
logistics. Liquid and gaseous fuels
generated from biomass will
achieve the breakthrough when
they can be supplied in a
standardised way and mixed with
or replace fossil oil and gas.
Wood pellets are the only
standard biogenetic fuel that is
currently available.
A great deal of interest is
currently being shown in these
boilers, which can generate
almost as much convenient heat
as oil or gas fired boilers using
this renewable indigenous fuel.

In a short statement, Dr.
Viessmann outlined the
opportunities that the heating
sector provided for long-term
energy and environmental policy.
He pointed out that an ambitious
environmental policy also
represented good economic
policy at the same time. “The
question is: How can
environmental targets be
combined with a positive trend,
i.e. combined with economic
growth?” asked Dr. Viessmann.
“In my opinion, for this to
succeed, framework conditions
must be set up that are linked to
controlling incentive
mechanisms.”
Dr. Viessmann mentioned the Eco
Management of Audit Scheme
(EMAS) and the Energy
Performance of Buildings
Direction (EPBD) as two good
examples of how Europe is
currently providing a congruence
of environment and economic
policy. The Eco Management of

National Energy Plan 2007 in preparation
Working parties deployed for main energy
policy issues
After the energy summit on
3rd of April in Berlin, to which
German Chancellor Angela Merkel
invited representatives from the
German government and leaders
of the business world (see also
leading article by Dr. Viessmann
on pages 2.3), important building
blocks will be developed for the
energy plan during the course of
the next few months. Three
working parties will be formed.
These will cover the following
areas:
the international arena
the national arena and
research and efficiency
These working parties will
formulate proposals covering
essential topics concerning
energy policy that will flow into
the overall energy policy plan, and
which will be presented at the
energy summit in Spring 2007.
The participants should therefore
develop forward-looking
contributions and include and
coordinate proposals from their
respective areas of study. The
important thing is for the results
to provide a coherent strategy by
the year 2020.
The next energy summit takes
place in the autumn of this year.
The Chancellor would like to
present some “tangible” results
by this time. The intention is to
make proposals on the
international aspects of this issue
for the German EU Council
presidency and the G8
presidency. The German
government also wishes to
present a program of actions
concerning the potential for
increasing efficiency and the
exploitation thereof in all
important areas for the action
plan that has been prescribed by
EU law for the end of 2007.
German Chancellor Angela Merkel,
Minister for the Environment
Sigmar Gabriel (l.) and Minister for
the Economy Michael Glos meet
representatives of the press at the
energy summit on 3rd April.
One of the tasks given to the
working parties is to identify main
areas for energy research,
whereby long-term strategies can
be given priority. The main focus
of the projects is on efficient
energy consumption, renewables
and basic research (new
materials, for example).
Improving export opportunities for
energy-efficient technologies is
also on the agenda. Among other
things, this is intended to bring
about an export initiative for
renewables, incentive instruments
in the developing world, linking
international climate protection
programs and new products and
services
(e.g. energy contracting and
decentralised energy systems).

2005 – Growth trend continues
Viessmann financial press conference in Frankfurt
Whereas the German heating
market shrank by 15% in 2005,
Viessmann continued its growth
and achieved turnover of about
1200 million Euros with its 7000
employees. During a press
conference, Dr. Martin Viessmann
informed those present in
Frankfurt of the company’s
situation.
In demand: The journalists made
good use of the opportunity to put
questions to the head of the
company.
Export business
compensates for weak
domestic market
Export sales made up for a weak
domestic market with growth of
18%. The export share increased
to 50%. The company succeeded
in holding its market position in
Germany, and Viessmann
increased its turnover in products
that use renewables by a third to
more than 140 million Euros. This
represents 12% of total turnover.
The company achieved growth of
some 30% in the heat pumps
sector. Turnover in the solid fuel
boiler area more than doubled,
and growth in the solar heating
system area exceeded 30%.
Approx. 50 million Euros was
spent on research and
development; 60 million Euros
were invested in assets. The main
investments were in the
expansion of the international
sales network, the modernisation
and expansion of the company
airfield and the implementation of
a new factory layout at the
company head office in Allendorf
(Eder).
The successful trend continued in
the first quarter of 2006 with an
increase in turnover of more than
10% compared to the same
period in the last year.
Martina Wewetzer, Chief
financial editor of the
Hessische/Niedersächsische
Allgemeine (HNA) newspaper,
conducted an interview with Dr.
Martin Viessmann during the
press conference, which was
published in the 29th April 2006
edition. The interview went as
follows:
Martina Wewetzer: The price of
oil and gas is increasing. Wouldn’t
it make sense to get away from
these fuels completely?
Dr. Viessmann: The slogan “away
from oil and gas” will prevent
modernisations that are
necessary and meaningful from
taking place, and lead to
excessive energy consumption.

of all energy that is consumed in
Germany. In the medium to long
term, an additional 50% of oil and
gas could be replaced by
acquiring and incorporating
renewables (biomass, geothermal
energy and solar energy).
We cannot do away with oil and
gas completely. However the
potential savings are tremendous.
The heating sector represents the
largest proportion, approx. 40%,
of energy consumption in
Germany. (vehicles/transport:
approx. 30%). If all of the two
million heating systems in
Germany that are more than 25
years old were modernised with
efficient oil and gas condensing
technology now, energy
consumption in the building
sector could quickly be reduced
by a quarter. This constitutes 10%
Martina Wewetzer: What are the
alternatives?
Dr. Viessmann: The most
economical alternative for
reducing oil and gas consumption
is to replace aging heat sources
with modern oil/gas condensing
technology. The investment of
4000 or so Euros that is required
to do this will pay for itself in five
years. Where independence from
oil and gas are the priority and
saving money is less so, it is
advisable to use a heat pump or a
solid fuel boiler such as a pellet
Company news
boiler. However, these products
are considerably more expensive
than oil or gas condensing
systems. A pellet boiler costs
about 10 000 Euros, and a heat
pump plus bore hole can cost
more than 20 000 Euros. At 10 to
15 years, the amortisation times
are therefore twice to three times
as long as with condensing
equipment, in spite of the
existing subsidy programs. The
main substitute for fossil fuels
(that also has the greatest
amount of future potential) is
biomass, which is available all
year round and comes in the form
of solid, liquid and gaseous fuels.
These can be mixed with (and
gradually replace) fossil oil and
gas as soon as they are available
to recognised standards and in
the correct form.
forgotten either. It can cover 60%
of the annual energy demand for
heating DHW, and is also used to
back up heating systems in an
increasing number of cases.
Martina Wewetzer: What do
mean by “the government has
been using the wrong approach to
determine subsidies”?
Dr. Viessmann: The subsidy
programs should be checked with
the aim of aligning them with the
level of energy savings in a way
that is independent of technology
and energy source. More of the
main focus should be on
supporting research rather than
applications. The whole of
Germany would benefit from this.

Location-consolidation measures
Modernised, extended
airstrip opened
The company airstrip at Allendorf
(Eder) was modernised and
extended last year at a cost of 10
million Euros. The official opening
took place on 24th May in the
presence of the president of
Hessen, Roland Koch.
As well as Roland Koch, many
guests of honour from the world
of politics and aviation were
present at the event, including
the president of the Hessen Air
Sport Association, Dr. Jens
Plusczyk, the Head of the Kassel
District, Lutz Klein, and the

providing a home for the
Ederbergland Air Sport Club.
Dr. Viessmann thanked the local
corporations and planning
authorities for dealing with the
building work in an unbureaucratic
fashion and also providing
financial assistance. The state of
Hessen, the Waldeck-Frankenberg
District and the Municipality of
Allendorf covered 30% of the
cost. Of course, the opening of
the airfield was not just about
speeches but flying
demonstrations. The take-off and
fly-over of a business jet
represented business operations.
The demonstration of historic
aircraft and gliders had to be
“Their attendance is evidence of
the high official regard in which
the Allendorf airfield is held as an
important constituent of the
infrastructure in this region”, said
Dr. Viessmann in his speech. The
head of the company also
reminded everyone of the early
days of the airfield, from which
the first aircraft took off in 1966.
Dr. Hans Viessmann started to
build the airfield in response to
the fact that the road links of the
region were inadequate for his
rapidly expanding business. “This
decision has proven to be correct
and far-sighted”, said Dr. Martin
Viessmann: “without air travel the
company would soon have
reached its limits; the export drive
that started in 1990s would not
have been possible, and the
airfield has therefore made a
decisive contribution to protecting
jobs and creating new ones.” The
entrepreneur also stressed that
the importance of the airfield was
not limited to business air travel,
and reminded everyone of the
cancelled because of strong wind.
However, the biplanes were
equally as impressive on the
ground.
The extensive building work at
the Allendorf (Eder) airfield
started in the spring of 2005. Lutz
Klein, head of the Kassel district,
handed the extended operating
license for the airfield to Dr.
Viessmann at the end of the
same year.
During the construction work the
landing strip was extended from
1090 to 1240 metres and
widened from 20 to 30 metres.
Instrument approaches are now
possible because of the
establishment of a controlled
airspace. This means that
appropriately equipped aircraft
can take off and land in weather
conditions, which would
otherwise not be possible under
VFR flying regulations.

Intensive dialogue between industry and trade
SHK spring trade fairs in Essen and Nuremberg
In the years when the ISH is not
taking place, the SHK technical
trade fair in Essen and the
ifh/Intherm in Nuremberg are the
most important meeting for our
sector in Germany. The SHK in
Essen has been the main trade
fair in the western part of
Germany for a considerable time.
The same applies to the technical
trade fair in Nuremberg with
regard to southern Germany.
Viessmann exhibited its full range
of products and services at both
events. Considerable interest was
shown in new products such as
the new Vitocom 100
communication interface and the
sub-mounting kit for the
Viessmann wall mounted gas
fired boilers (see also product
articles on pages 20 and 21), and
above all the oil and gas
condensing boilers and products
that utilise renewables.

The ambience was light and
transparent, and the products
were clearly exhibited in separate
groups in several different subject
areas. The Viessmann stands
were regularly packed with
visitors.
About 80% of the visitors to the
Viessmann stands were
specialists from the SHK trade.
This shows how intensively both
fairs are used for a technical
dialogue between industry and
trade. In a countless number of
discussions it emerged that the
combination of condensing

Viessmann Baltic countries: Looking to the future with optimism
Environmentally friendly heating equipment for an

“Little Wave” in the Baltic countries
The Lithuanian capital of Vilnius
The three Baltic countries of
Lithuania, Latvia and Estonia
are still a mystery to much of
western Europe. They have
been independent states since
1990 and became members of
the European Union two years
ago. The “Baltic Tigers” as they
are called, just like the
emerging tiger states of southeast Asia, have enjoyed aboveaverage economic growth for
several years. Lithuania is the
biggest country of the three,
and is mainly famous for being
the first Soviet Republic to
declare its independence.
Sporting connoisseurs will
already know about the
country’s basketball team,
which is one of the best in the
world.
The Lithuanians are extremely
proud of their recent
independence, something which
has been a rarity for several
centuries. Lithuania was at the
intersection of the political and
economic interests of the German
16
Order, the Polish crown and the
Russian Empire. The country was
under Polish, German and Russian
sovereignty, then became part of
the Soviet Union, and now the
Grand Duchy of Lithuania has
finally achieved independence.
same applies to its Baltic
neighbours of Latvia and Estonia;
they are called “Baltic Tigers” for
good reason.
Germany and Russia are now
Lithuania’s main trading partners.
Since the establishment of the
state of Lithuania, the country
has become extremely
westernised in order to gain
direct access to the markets of
the European Union and make it
less dependent on its Russian
neighbour. The country joined the
European Union in order to do
this. The next step will be the
introduction of the Euro, since
Lithuania has already joined the
exchange rate mechanism II,
according to which the exchange
rate has to remain stable within
certain limits. The result: The
economy is booming, helped by
the low corporation tax and
contributions that have attracted
many companies to the country,
particularly from Scandinavia. The
Vilnius is the capital of Lithuania.
In accordance with its multiethnic and multicultural character,
it is known by several names and
is usually referred to as Wilna in
Germany. The translation of the
name is something like “Little
Wave”, which is probably a
reference to the almost identically
named river, the Vilnia. Many
people refer to Vilnius as the
“Rome” or “Jerusalem of the
East”. The former is a reference to
the many churches and
monasteries, which originate from
the country’s days as a Catholic
outpost in the east. The
comparison with Jerusalem goes
back to Vilnius’ role as a spiritual
and cultural centre of the Jewish
culture in eastern Europe.

the Neris and the Vilnia,
constituting approx. one sixth of
the country’s population.
With an area of 360 hectares, the
centre of Vilnius is one of eastern
Europe’s largest preserved
historic town centres and was
included in UNESCO’s world
cultural heritage list in 1994. The
architecture of the 1500 or so
historic buildings ranges from
early Gothic to Renaissance and
Baroque to Classicism and Art
Nouveau. These form a
townscape that is unique in
eastern Europe. It can thank its
churches for its unmistakable
appearance. The cathedral, dating
back to the 13th century, is the
oldest church in the city and
bears witness to the age of
Christianisation. For centuries,
grand dukes, bishops and Polish
rulers have found their final
resting place in its catacombs. In
the 19th century it was adapted
to the fashion of the period and
converted to the Classical style.
Portrait
Vilnius has one of the largest
preserved historic city centres in
eastern Europe.
St. Anne’s church is considered to
be a masterpiece of Lithuanian
High Gothic and north-eastern
European brick architecture. The
master builder designed no fewer
than 32 different bricks for this
building alone. But the
“wastefulness” stopped there,
because the interior has the
typical minimalist Nordic Brick
Gothic style, which displays no
ornaments or opulent decoration
whatsoever. St. Bernard’s
monastery adjoins St. Anne’s
church. It was founded in 1462 by
Polish monks at the height of the
Christianisation movement. The
associated St. Bernard’s church
was used for another purpose for
many years, and little of its
original internal structure remains.
Restoration of the entire complex
has been under way for some
time, and experts are exposing
the frescos and vaults layer by
layer. It will probably take years
for the full history of its many
hidden treasures to be finally
revealed.

Vilnius claims to be at the centre
of Europe, and cites the National
Geographical Institute of France,
which recorded in 1989 that the
geographical centre of Europe
was just 24 kilometres away from
Vilnius. Vilnius is now a
multicultural city; 58% of the
population are Lithuanian, 37%
come from neighbouring
countries Poland, Russia and
Belarus, and the remainder
consists of a mixture of different
nationalities. The diverse
architectural style and the ethnic
mix of this city is held in high

The new Vitocom 100 with GSM
technology provides a convenient
and affordable remote control
facility via mobile phone.
Vitocom 100: Remote control
by mobile phone
It’s now even easier to operate
your boiler remotely. Thanks to
the new Vitocom 100 with GSM
technology, this can be done
conveniently and economically
using your mobile phone.
GSM stands for “Global System
for Mobile Communications” and
is an international mobile radio
standard. Neither a land line nor
cable laying is required with the
new Vitocom 100 GSM. All
communication is wireless by
transmitting and receiving text
messages. System users can
conveniently operate and monitor
their boiler using prepared text
templates. Other equipment such
as the fuel oil supply can also be
monitored. If problems occur, the
Vitocom 100 also sends
immediate notification to the
heating engineer via text
message.
The free choice of mobile phone
provider and the use of standard
commercial mobile phone SIM
cards keeps the remote control
operating costs to a minimum.
The Vitocom 100 GSM can also
be easily retrofitted to Viessmann
freestanding and wall mounted
boilers.
New addition to the heat pump range: Vitocal 200 in
made-to-measure package for detached houses
As well as the proven Vitocal 300
heat pump (4.8 to 106.8 kW), the
Vitocal 200 (6.1 / 7.7 and 9.7 kW)
brine/water heat pump is also
available, which is specially
designed for the heating
requirements and demands of
detached houses and combines
top quality technology with an
attractive price. The new
complete packages consisting of
the Vitocal 200 heat pump, a
DHW cylinder, a cylinder
temperature sensor, a diaphragm
expansion vessel and flexible
connecting technology for the
18
heating circuit and DHW heating,
makes heating with ambient heat
even easier.
A degree of DHW convenience is
extremely important in modern
houses. The Vitocal 200,
combined with a suitable DHW
cylinder, meets these demands all
year round in mono-mode
operation. The multi-connect
system makes it quick and easy
to fit the heating and DHW
connections. Brine and heating
circuit pumps and changeover
valves are integrated in the heat
pump. All components of this
comprehensive package in the
proven Viessmann quality are
matched-up, ensuring a
comfortable supply of heat all
year round in mono-mode
operation.
The maximum flow temperature
of 60 °C also means that the
equipment can be used in
combination with radiators. The
weather-compensated control unit
allows two heating circuits to be
connected and also provides a
natural cooling function.
The Vitocal 200 is available together
with the Vitocell-B 100 (300 litres)
and Vitocell-V 100 (model CVW, 390
litres) DHW cylinder.

Vitomax 200 HS:
Integrated feed water pre-heating saves energy
Vitomax 200 HS high pressure
steam boilers with steam output
of up to 25 tons per hour are
among the heat generation
“heavyweights”. Separate flue
gas/water heat exchangers (socalled economisers) are often
connected downstream of the
boiler so that these steam boilers
can be operated economically.
The boiler feed water is preheated inside these economisers,
which helps to achieve an overall
efficiency level of up to 95%.
Since this can reduce operating
costs considerably, economisers
are gaining rapidly in popularity.
The Viessmann Vitomax 200 HS
steam boilers are, therefore, now
optionally equipped with integral
economisers. This saves space
and cuts down on the scope of
expensive pipelines and fittings
that are needed for separate
economisers.
The economiser that is integral to
the Vitomax 200 HS saves space
and additional installation work.

Viessmann heat pump for the
"Agricultural and Winter Sport Museum”
Markus Wasmeier is one of
Germany’s most successful
skiers, having won many
medals at World Championships
and Olympic Games. Now,
Markus Wasmeier has changed
direction entirely. For some
time he has been investigating
the cultural history of his home
town and has constructed an
original Bavarian museum
village. The “Markus Wasmeier
Agricultural and Winter Sport
Museum Schliersee e.V.” has
been conceived to remember
the agricultural history of the
region. Viessmann donated a
heat pump to the museum that
will heat the “Wofen”, the
culinary centre.
Part of the museum village will be
opening this year. It is intended to
show visitors how people lived
and worked on farms in the past.
And all this in an idyllic setting
with a view of the Wendelstein,
covering an area of 60 000 square
metres. The village consists of a
collection of traditional farms in
the region. The farms are
purchased, dismantled at their

provided a Vitocal 300 brine/water
heat pump, model BW 232 with
32.6 kilowatts to do this, and also
a Vitocell 050 buffer cylinder with
a capacity of 900 litres. The probe
drillings were completed in
March, and the heating system
was commissioned in April. It
took the “BauGrund Süd

about nine days to drill the five
holes, which were up to 100
metres deep. Now the 32 x 2.9
millimetre probes are extracting
heat from the ground. The heat
pump brings this to the required
temperature level and with that
energy heats the buildings and
the hot water for twelve months
of the year.

Energy saving in historic buildings
Villa Seeblick on Usedom is heated by
Viessmann technology
Historic buildings usually require
significantly more energy than
modern housing – particularly if
they were built more than 100
years ago, when insulation and
energy consumption were not an
issue. The fact that even a 130year-old preserved building can be
upgraded to the level of a low
energy house can be seen from
the example of Villa Seeblick in
Heringsdorf on Usedom.
The Baltic Sea spa of Heringsdorf
was founded in the mid-19th
century as a spa and resort. Many
villas were built at the time, and
they now dominate the
appearance of the town. When
you walk through the streets and
along the promenade you can
savour their imperial flair and their
old, quaint architecture, time and
time again.
building in an appropriate way and
modernise the energy supply. The
plan was to create 450 square
metres of living and usable floor
space with five apartments on
three floors, and a gym in the
basement.
The roof was reconstructed in the
same style, using an historic
model as a guide, and the
brickwork and granite foundation
were dried. The floor, the exterior
walls and the roof were fitted
with extremely efficient
insulation. Since the villa is has a
preservation order, special
regulations had to be complied
with. This meant that the facade
could only be insulated from the
inside, since external insulation
would have changed the
appearance of the building.
However, Villa Seeblick, which
was built right next to the
promenade in 1876, was in a bad
state. The roof was leaking, the
facade was deteriorating, and the
walls were damp. The heating
system was totally out of date.
There was a considerable energy
demand of 452.6 kilowatt hours
per square metre per year. Both

architect Ulrich Zink, the objective
was to restore this remarkable old

engineered by the Deunert design
office in Berlin and the Wolfgang
Horn heating contractor from
Demmin, which also installed the
equipment.
Modern heating technology
combined with efficient insulation
reduced the energy demand at
Villa Seeblick by about 89% to a
mere 47.7 kilowatt hours per
square metre. This puts the
130-year-old building at the level
of a new building and shows that
it is possible to integrate energy
saving measures in an old
building successfully.
The builder and the architect
decided on a Vitosol 300
brine/water heat pump and a DHW
cylinder to provide the heating.
Now that the extensive restoration
work is complete, Villa Seeblick has
been restored to its full glory.

Pragelato: Vitoplex 100 heats Olympic village
The village of Pragelato is about
80 kilometres from Turin, at the
foot of Monte Albergian at an
elevation of 1500 metres. In the
spring of this year, this village and
its 460 inhabitants were the focus
of world attention. This is where
cross-country skiers, ski jumpers
and Nordic combination athletes
were competing for medals in the
20th Winter Olympics. Viessmann
athletes Björn Kircheisen (Nordic
combination) and René
Sommerfeld (cross-country skiing)
both won silver medals in the
relays.
During this time,the IOC
members, organisers and
journalists stayed in a new hotel
complex; the complex was
incorporated into the alpine
countryside in a highly
sympathetic way. A “Hotel
Village” consisting of 87 individual
buildings containing 205
apartments for up to 1000 visitors
was built on five hectares of
thinly wooded hillside. The village
character was created by
arranging groups of 4 or 5
buildings into a so-called
residential courtyard. As is the
norm in Italian villages, the hotel
complex in Pragelato forms a
square in the centre of the
village. The public areas are
arranged around this: there is a
main building with reception and
also restaurants, shops,
conference rooms and an
administration office. A fitness
centre and a Bambini Club for the
little ones rounded off the tourist
facilities.
20 such complexes were
erected by Haas Fertigbau GmbH
in just 15 months.

considerable experience in the
construction of prefabricated

houses consist of identical
standard elements which allow
the houses to be erected within a
short time, but they are also

architect’s office based the design
of the hotel system on the
traditional building style of the
region. The roofs were covered
with the larch wood shingles and
natural stone slates that are
typical of the region, and wooden
gutters were fitted.
Each residential courtyard is
heated by a Viessmann Vitoplex
100 low temperature boiler.
Natural gas is used as fuel, which
is transported into the mountain
region by pipeline. The designers
from the Chemnitz-based

Impressive achievement
16 medals for the Viessmann team in Turin
The members of the Viessmann
team proved to be keen medal
collectors at the 20th Winter
Olympics in Turin. They won a
total of 16 medals in the biathlon,
the Nordic combination and the
cross-country skiing.
The most successful of them all
was Sven Fischer in the biathlon
in San Sicario. As well as a
coveted gold medal in the
individual competition (sprint), the
34-year-old from Thüringen won
another gold in the relay and a
bronze in the pursuit. Martina
Glagow won three medals in the
women’s events – silver in the
individual, the pursuit and the
relay. Andrea Henkel also took
silver in the relay, and just missed
out on a medal in the individual
competition, coming in fourth
place. Uschi Disl finished her
career with bronze in the mass
sprint in her final winter
Olympics. This exceptional
biathlete, who has been part of
the Viessmann team since the
98/99 season, has now retired.

Italy’s Pietro Piller won two
medals in the cross-country
skiing. The gold medal that he
won in the relay with Christian
Zorzi was celebrated with all the
exultation of a miracle in the host
country. As he said himself, his
bronze medal over 30 kilometres
in the pairs pursuit was the “icing
on the cake”. Gabriella Paruzzi
proved that her medal winning
ability was not a fluke by winning
a bronze in the relay; she can put
this next to her 2002 gold medal.
The trainer teams in the
toboggan, the Nordic combination
and the cross-country skiing,
which were all supported by
Viessmann, saw their protégés
win a sackful of medals. The
toboggan team trained by Thomas
Schwab won one gold, two silvers
and a bronze medal. Head of the

The spirit of the Turin games brought to Allendorf:
Olympic Welcome Party 2006
The outstanding performance of
the athletes at the 20th Winter
Olympics in Turin impressed
spectators both at the event itself
and on television screens around
the world. Just two days after the
Olympic flame was extinguished
in Turin, Viessmann welcomed the
athletes that had been sponsored
by the company to Allendorf
(Eder). High-ranking politicians,
including the Hessen Interior
Minister, Volker Bouffier,
representatives of the sports
associations, trainers, media
representatives and customers
from twelve countries were also
among the 500 guests.
The company honoured the
athletes and thanked them for
their sporting achievements and
successes at the Turin games at

The Olympic spirit of the Turin
games was alive in the hangar
with Italian specialties and music,
and the re-lighting of the Olympic
flame. TV presenter Ursula

in which the sportsmen and
women gave their impressions of
the two weeks in Turin. The
evening revolved around a
program of exciting shows, with
an impressive range of dancing,
singing and acrobatics.

conventional athlete/sponsor
relationship. Hackl developed and
manufactured the high-tech
runners of his toboggan together
with experts from the Viessmann
stainless steel production team.
“At the official end of your career
I would like to thank you and
express my admiration of your
achievements in your sport, and
also of your conduct as an
ambassador for the company”,
said Dr. Viessmann, “and I hope
that our partnership will continue

Early function diagrams for generating heat
using alternative energy sources
The energy crises of the 1970’s
lead to increased demand for
heating sources that were
independent of oil and gas. Most
of these were heating systems
that used renewables. However, a
return to coal and coke heating
took place, whereby
developments in comfort
requirements became established
that were oriented on oil and gas
fired heating.
At that time, Viessmann brought
heat pumps, solar heating
systems and gasification units for
heating with wood pellets onto
the market. Coal and coke boilers
with fully automatic charging and
units for converting kinetic energy
into heat completed the range of
innovative heat sources for
alternative energy sources.
These new technologies were not
just a challenge to researchers and
developers, but also for graphic
designers who had to implement
completely new design principles
and processes in the function
diagrams of Viessmann brochures.
A diagram with eccentrically
arranged circles was created for
heat pumps; this diagram showed
how ambient heat is utilised by
means of compression and
transferred to water – here using a
yellow and red colour scheme on a
blue background. The principle of
