A longside the increasing digitaliz-ation, the energy transition is

among the major challenges of our times. Although European policymakers and media are currently concentrating on other issues such as accommodat-ing and distributing refugees, the econ-omic developments in China and the unsolved Ukraine conflict.

UN World Climate Conference in ParisHowever, energy efficiency and climate protection are at the focus of the UN World Climate Conference 21 in Paris. Europe will be expected to make a clear statement as to whether its member states will be able to reduce their CO2 emissions compared to 1990 and, as a result, meet ambitious climate targets . Germany has com-mitted itself to cutting its CO2 emissions by as much as 40 percent, a higher percentage than required by the European target. The German Chancellor will feel obliged to confirm that this objective will be achieved. However, it has now become clear that the measures implemented so far are not sufficient. A gap of 22 million tonnes of CO2 still has to be closed. But how?

Policymakers turn to the heating marketThe ministries in Berlin have been con-sidering new approaches. One of their responses involved introducing a cli-mate levy on coal-fired power stations with the objective of squeezing old plants out of the market. However, this option met with massive resistance from the state of North Rhine-West-phalia and the trade union IG Bergbau, so it never got off the ground.

Policymakers therefore turned their at-tention back to leveraging the consider-

The energy transition remains a tremendous challengeThe heating market is the key to meeting climate targets

able potential offered by the heating market. It is very unfortunate that they seem to have permanently shelved the plan to give tax breaks for refurbishing buildings in an energy-efficient manner this year, as tax breaks would have succeeded in waking the "sleeping giant". They therefore need new con-cepts to ensure the success of the National Plan of Action for Energy Efficiency (NAPE).

Regulatory law unsuitable for triggering investmentRegulatory law has been ineffective in enhancing energy efficiency in existing buildings or promoting the use of re-newable energy. Homeowners cannot be forced to invest in their buildings. The introduction of scrapping incentive programs can also be problematic, as witnessed in the automotive sector some years ago.

Targeted and reliable incentivesA policy of targeted incentives seems to be more promising. It is essential that these incentives are

calculable, reliable,technology-neutral and fuel-neutral.

In the absence of tax breaks, the cur-rent German development bank (KfW) programs and the market incentive pro-gram (MAP) could help achieve the tar-gets – providing they are endowed with sufficient funds, continued on a perma-nent basis, simplified and communi-cated effectively to the general public.

Label for increasing energy efficiencyAnother step in the right direction is the introduction of the energy efficiency label for heat generators in compliance with the ErP Directive (Energy-Related Products Directive). These labels have been mandatory since September 26,

2015. As a result, throughout Europe, new heat generators,

oil and gas boilers,heat pumps,micro- and mini-combined heat and power generation systems,and DHW generators

are rated in energy efficiency classes and labeled accordingly.

Greater transparency for investorsThe introduction of these labels, which range from the dark-green colored "A++" class to the deep-red colored "G" class, will provide much greater trans-parency for investors in new builds and modernization projects. It will promote the use of more energy-efficient pro -ducts, a trend which policymakers are wanting to reinforce.

Comprehensive ErP service packageAs heating systems are made up of several components and are increas-ingly offered as bivalent and multivalent systems, each heat generator also needs a package or universal label for the entire system in addition to the product labels. Producing these labels is a challenging task for trade profes-sionals. For this purpose, Viessmann provides free software to its market partners as part of the company's com-prehensive services portfolio, enabling trade professionals to produce the necessary documentation quickly and easily for investors.

Labels for existing systems to raise awarenessIn Germany, from 2016, labels will also be required for existing systems in addition to those for new products. Following a suggestion by trade associ-ations (Federal Association of German House, Energy and Environmental Technology and the German Central

3Association for Plumbing, Heating, and Air Conditioning), the German Federal Ministry for Economic Affairs and Ener-gy plans to classify old systems into energy efficiency classes and label them accordingly, as an integral part of the National Plan of Action for Energy Efficiency (NAPE). The objective is to raise awareness among homeowners for the problem. At the same time, they will be informed about the benefits of modernizing systems and different funding options.

At the moment, three-quarters of the 20 million heat generators in Germany homes are still not state of the art. In the future, chimney sweeps, energy consultancies or trade professionals will be responsible for labeling existing systems, with the aim of helping to tackle the modernization backlog.

Key markets starting to recoverThis would boost the industry consider-ably and, above all, help policymakers to achieve their climate targets. The prospects are not bad. Although the political framework is not ideal, there

are signs of a positive trend for the current business year, after the market volumes having shrunk in many Euro-pean countries in 2014. The markets are in the process of recovering or stabiliz-ing in Germany and most Western European countries with considerable sales potential such as France, Italy or Spain. The same applies to Turkey and numerous Eastern European countries such as Poland, Romania or the Czech Republic. The North American markets have also developed stably. One negative aspect, however, is that the demand for renewable energy products has not yet fulfilled expectations.

Hybrid devices offer sustainabilityAt Viessmann, we are happy with the business year so far. In par with the overall market developments, we have especially recorded substantial growth in the sales of efficient gas and oil heat generators. We are well prepared for the challenges ahead, in particular with the family of hybrid devices we pres-ented at the ISH, regardless of how the prices and availability of different fuels develop in the future. This is the only

way we and our market partners can offer our customers solutions that guarantee efficient, environmentally friendly and economic heating of their homes even far into the future. Digital solutions are essential in this context. Our hybrid devices are therefore al-ready able to react to the future price signals of energy suppliers and auto-matically optimize their operating mode accordingly.

Reduce uncertainty for investorsDear partners, we have to face some major challenges. However, opportun-ities will continue to open up which we can jointly exploit. Homeowners are currently still very willing to invest. And there are no signs that interest rates will rise significantly in the fore-seeable future. It is decisive that we, as experts, are able to reduce the in -securities of investors and to offer sustainable solutions. As always, we will remain a reliable partner for you and ready to provide you with support at all times.

Andreas Kuhlmann has been Chair-man of the Managing Board of the German Energy Agency (dena) since July 2015. Before that, he was head of the for strategy and politics division with the German Federal Association of the Energy and Water Industry (BDEW).

GUEST ARTICLE

Over the last year, developments in the energy efficiency of buildings

have gained momentum: In December 2014, the German government ap-proved the German National Plan of Action for Energy Efficiency (NAPE) parallel to the German Climate Protec-tion Action Program 2020. These initiatives incorporate measures, such as increased funding for building modernization or the development of energy consultancy, that constitute initial essential steps. However, the German government is now called upon to rapidly implement these ap-proaches and instruments. Above all, it needs to provide more incentives to boost the rate of modernization which has been stagnating at around one per-cent for years. Its failure to introduce tax benefits has dealt a heavy blow which will be difficult to counteract.

The market players now require more extensive and intensive energy con -sultancy, a reliable and effective in-formation policy and model projects that set standards for widespread implementation. Over the past years, the German Energy Agency (dena) has acquired experience in these areas with numerous campaigns and pilot projects and has elaborated efficient instruments and standards.

The heating transition gathers steamby Andreas Kuhlmann

Viessmann has been a long-standing partner of the German Energy Agency (dena) for many of these projects. We are both involved in the German Al-liance for Energy Efficiency of Buildings (geea), a coalition of leading companies and organizations related to energy effi-ciency in the building sector. Together with the German government and many other players, we launched "Hauswende" – the first countrywide, cross-sector, sustainable housing ener-gy campaign – last year. The result is impressive: We have informed house owners about the modernization of energy systems with more than 150 events and over 500 items published in print and online media to date. We need to keep up the good work – the only way of pushing ahead the energy transition on the heating market is through close collaboration between all important players.

In the last issue we asked our German readers to take part in a survey with the aim of making our magazine even better. After evaluation of the numer-ous responses received, the results can be summarized as showing the main feedback to be very positive, but with here and there some room for im-provement.

Almost 90 percent of respondents rated the "aktuell" as "good" or "very good". Most of the subscribers read every edition with a medium to high level of attention, that is, they deliber-ately take the time to read it. The feedback on the layout of the magazine is very positive, and the choice of topics is generally considered good. A frequently expressed wish was for more technical subjects and more reports about practical experi-ence.

Most of the readers would prefer to continue reading the print version of the magazine in future, too, with one in three also open to receiving the digital version.

The "aktuell" editorial team thanks all those who took part and will gradually implement the suggestions made.

The winners of the three gift vouchers for the Viessmann Selection Shop with a value of 100 euros have been be notified in writing.

Viessmann had acquired 50 percent of Hexis AG in 2012 and has now com-pleted the acquisition of the Swiss company. In taking this action, the Viessmann Group is making a clear commitment to highly efficient, low-CO2 fuel cell technology.

Hexis is acknowledged across Europe as a specialist in the field of micro CHP systems on the basis of high-tempera-ture fuel cells (SOFC). SOFC fuel cells achieve a high degree of electrical effi-ciency. With the complete acquisition of the company, Viessmann is ensuring the continuity of this fuel cell specialist at their development and production site in Winterthur.

awarded first place for this. This goal was achieved partly as a result of instal-ling a Viessmann biogas system for energy recovery.

Viessmann has been collaborating with UWO since 2011. An exchange program was set up for students from Oshkosh and Viessmann trainees, alongside several joint projects and an endowed professorship for sustainable technology.

The Viessmann magazine "aktuell" is in its 47th year of publication.

The energy efficiency identification, called ErP labeling, of heating technol-ogy products has been compulsory since September 26, 2015. Viessmann provides product labels and fact sheets for heat generators, DHW generators and cylinders from their comprehen-sive range of products. Complete heat-ing systems installed since this date have to be marked by the tradesman with a universal label. Viessmann has created a comprehensive service pack-age to help their market partners meet this requirement. For more information, read the article on pages 2 and 3 in the Fachnews No. 39.

The Mediterranean countries of Italy, Spain and the Balkans are among the oldest economic regions in the

world. Life in these regions takes place against the back-ground of a Mediterranean climate, impressively beautiful scenery and sites rich in history.

Italy has a gross domestic product (GDP) of 1.6 billion euros and a population of 60 million, making it the fourth largest economy in the European Union after Germany, the United Kingdom, and France. It is followed by Spain with a popu-lation of 47 million and a GDP of just a little more than one billion euros. Italy, Spain and also the Balkan states have suffered in recent years as a consequence of the financial crisis around the euro.

Although efforts to turn the economy round are bearing first fruits, huge challenges remain. In Spain, this mainly means the creation of new jobs, particularly for young people, since the unemployment rate for young people is almost 50 per-cent, while in Italy it also means overcoming the north-south divide. The Balkan states of Slovenia, Croatia, and Serbia/Montenegro have now emerged from their economic isolation and have opened up as new, important markets. The long overdue upgrading of the infrastructure and the reduction of the modernization backlog, particularly on the heating market, are common features of the southern European countries.

Italy

Gas is the dominant fuel source in Italy and almost 70 percent of all existing households are heated with natural gas. Solid fuel boilers are not insignifi-cant with a market share of 14 percent. Oil and electricity have a subordinate

role on the heating market. The trend is towards natural gas.Only a few markets in Europe have such a small product mix as the Italian market. 97 percent of newly installed heat generators are wall-mounted gas boilers and two thirds of them work on the basis of standard technol-ogy. This will change, however, when the ErP Directive (Energy-Related Products Directive) comes into effect: Condensing boilers are expected to be dominant for new installations in the coming year.

Additionally, new guidelines for new builds have also come into effect this year in Italy. They stipulate that at least 35 percent of the energy demand for building heating must be covered by renewable energy systems; for domestic hot water this has to be at least 50 percent. The new regulations will have a posi-tive effect on the sales of drinking water and heating water heat pumps, while the natural cooling function of Vitocal heat pumps offers a real benefit for homeowners in a warm country such as Italy.

The trend is now upwards after years of decline, although it is not expected that there will be a noticeable upturn in the coming years. The Italian economy has been clearly in decline since the Euro-pean banking crisis of 2008, with the unemployment rate still rising and now standing at 13 percent. New building is also at a low level, with around 120,000 houses and apartments.

The Villa Barozzi is idyllically situated on the eastern bank of Lago Maggiore. Condensing technol-ogy, here in the form of a Vitocrossal 300 boiler, is used to heat this building, modernized in 2010, in an efficient manner.

Milan has around 1.3 million inhabitants and is the second largest city in Italy. Milan Cathedral was completed in 1858 and is a symbol both of the city and of the region of Lombardy.

Spain

The general economic situation is even more dramatic in Spain, but there are signs of a recovery. Last year, for the first time since 2009, a small amount of growth could be measured, and the unemployment rate went down from more than 26 percent to 24.5 percent.

Moreover, forecasts predict that 2015 marks the lowest point in the new build sector and that the market will grad-ually recover after losing two thirds of its volume in recent years.

The same is true of the heating technology market. The estimates for 2015 predict clearly noticeable growth;

a trend that should continue and strengthen in the coming years.

Oil was the leading fuel source in Spain up to the 1990's, with hard coal also very common. Today most buildings are heated with natural gas and renewable energy is also gaining ground. Just as in Italy, non-condensing or low tem-

perature technology is still dominant in Spain. Condensing technology will be-come compulsory, however, because of the ErP label. The modernization backlog is very high and most residen-tial buildings are in bad condition from an energetic point of view. That is true of systems engineering as well as of insulation.

In Spain, there are hopes of an upturn in the market as a result of a new legal regulation requiring an energy certificate for new buildings and also for existing buildings that may be sold or rented out. Moreover, the "Codigo Técnico" (CTE) stipulates that renew-able energy systems have to be used for DHW generation in new buildings.

Biomass boilers, air/water heat pumps and especially solar heating will benefit from it.

Croatia, Slovenia, Serbia, and MontenegroIn the Balkan states of Croatia, Slove-nia, Serbia and Montenegro, gas, bio -mass, and electricity are important fuels used in heating buildings. The energy mix varies however from region to region.

While logs and hard coal are dominant in rural areas, district heating and gas are the main fuels in urban environments, depending on the infrastructure. The Balkan states, like the countries of the EU, are members of the European Ener-

gy Community that was formed in 2006. The aims of the Community are to strengthen cross-border supply security, to improve energy efficiency and to ex-tend the use of domestic fuel sources. All the Balkan countries are thus inte-grated into EU energy policy.

By contrast, the political integration of the Balkan states varies very much from one country to another. While Croatia and Slovenia are already members of the EU, Serbia and Montenegro are can-didate countries for EU accession and

Bosnia and Herzegovina is a "potential candidate country".

After years of recession and stagnation, the heating technology market is now slowly getting going again. The ErP Di-rective (Energy-Related Products Direc-tive) will mean that condensing technol-ogy becomes more important, es-pecially in Croatia and Slovenia, while there is a greater demand for renewable energy systems, such as solid fuel boilers, solar thermal systems and heat pumps, in the Balkans.

Own sales company in Italy since 1992The Viessmann sales company in Italy was founded 23 years ago. Previous to this, business was carried out with the help of an importer. From the beginning, the North Italian city of Verona was the headquarters of the organization. This is divided into three domains that each work the markets with their own company.

Six sales officesThe founding company, Viessmann Srl, is still responsible for the sales network. There are sales offices in Bolzano, Florence, Milan, Turin, Venice, and of course in Verona itself.

Viessmann in Italy, Spain and in the BalkansOvercoming the economic crisis with commitment and innovation

Competence center in Brixen"Viessmann Engineering" looks after the systems engineering business. This company was founded in 2011. Business activities are also controlled from Verona, while the competence center of Viessmann Engineering is located in Brixen. The generously sized building has seminar and exhibition rooms and is also a competence center for biomass. This fuel source is very common in South Tyrol with its many forests.

"Nuove Energie Viessmann Group"The "Nuove Energie Viessmann Group" was founded in the middle of last year. It was founded after acquisition of the Schüco photovoltaics business by Viessmann Photovoltaik GmbH, and it has its headquarters in Verona as well as a sales office in Padua.

250 employeesAltogether, around 250 employees work for the three businesses, 200 for Viessmann Srl and 25 each for Viess-mann Engineering and Nuove Energie.

Energy-efficient heating technology for SpainViessmann activities on the Spanish market started as far back as 1993. The three-man team started by working from the Managing Director's private residence. The first company building was opened in Getafe near Madrid a few months later and the company's own Technical Service department was started up.

At that time the main fuel sources in Spain were oil and hard coal. Viess-mann was the first company to intro-duce energy-efficient products into the

MARKETS: SOUTHERN EUROPE

duced to the market solar heating, thenrarely seen and wall-mounted units for gas and oil. Some time afterwards, a new building was opened up in Madrid, considerably larger and moreimposing than the old one.

Need for efficiency coveredThe economic crisis caused by the bank crash in 2008 did not spare the heating technology industry either. But Viessmann Spain saw the challenge as an opportunity. For thefirst time, energy efficiency was talked about by the public as well as by politicians. So new, particularly efficient products such as bio-mass boilers, heat pumps and CHPunits were included in the range of products.

Cooperation with contractorsIn addition, Viessmann Spain has re-cently been cooperating with energy contractors. The latter usually carry outcomplete modernization of a buildingand finance the project themselves from the savings that have been made,without having to charge the costs ofmodernization to the end customer.That is a good alternative solution in economically difficult times, since many homeowners cannot or will not pay to upgrade their heating system.

Growth in the last yearThese measures have helped Viess-mann Spain to set the business in apositive direction again despite pre-vious indicators of difficulty, and since2014 the company has been growingonce more.

Active in the Balkans since 1996Slovenia was the first country in theBalkans where Viessmann started up.In 1996, a sales company was founded in Maribor for this purpose. A year later, there was a market launch in Croatia and in 2004 in Serbia. The three subsi-diaries are also responsible for the countries of Bosnia and Herzegovina, Montenegro and Macedonia.

At the start of activities there was astrong demand for medium-sized andindustrial boilers for industry and dis-trict heating, and later also for wall-mounted gas boilers in standard tech-nology for home heating. However, the current trend is mainly for condensingtechnology and renewable energy sys-tems. The whole Viessmann productportfolio is sold in the Balkan states,ranging from the domestic hot water heat pump to CHP units to the 20 MWbiomass boiler.

Verona – a name that excites both city tourists and music

fans. It is no wonder that the metro -polis of 260,000 inhabitants in the north of Italy is considered one of the most beautiful cities in the country. The old town has been a World Heritage Site since 2000, and in summer the world-famous opera festival is held in the Arena there.

Verona – city of opera and romancePrimary location of the Viessmann group in Italy

History going back thousands of yearsVerona was originally a Celtic settle-ment and in 89 B.C. became a Roman colony. In 489 A.D. Theoderich, King of the East Goths, conquered the city and made it his residency. 80 years later it fell to the Lombard King Alboin. Verona received its town charter in the 12th century, but kept on falling into

different hands. It only became part of the Kingdom of Italy in 1866, after many battles for freedom.

Romantic, lively atmosphereThe image of Verona is strongly in-fluenced by its eventful past. The city owes its romantic and very lively atmosphere to the many statues, frescoes, gateways, inscriptions, medi-

15

MARKETS: SOUTHERN EUROPE

eval windows, fountains, little squares, and inner courtyards. William Shakes-peare immortalized Verona when he set

the most famous love story in the world here. The (assumed) houses of Romeo and Juliet attract many tourists all year round.

Most important opera festival in the worldEven more famous is the wonderfully preserved Arena of Verona, now inte-grated into the present city, which was built in the first century by the Romans from white and red limestone. It is the second largest amphitheater in Italy after the Colosseum and measures 152 meters in length and 123 meters in width. It can seat 13,000 spectators and dominates the famous Piazza Bra. In summer, the Arena hosts the largest and most important opera festival in the world. Up to 500 singers, dancers, musicians, and extras are on the stage at the same time, if either "Carmen" by Georges Bizet, or "Aida" or "Nabucco" by Giuseppe Verdi are being performed.

Excellent transport linksVerona has excellent transport links. At the railway station Porta Nuova, one of the most important railway junctions in Italy, the Brenner line Bologna–Inns-bruck and the line Turin–Milan–Venice

cross. Verona is also a junction in the Italian highway network: At this point, the Brenner highway A22 meets the European Road 70 that goes from Spain to Georgia straight across the continent. The international airport "Valerio Catullo" is used for both civil and military air traffic.

Major economic importanceThe good transport links make a sizable contribution to Verona's major econ-omic importance. Tourism has tradition-ally been one of the most important economic sectors; the neighboring town of Vicenza is also known as a center for the goldsmith's craft. There are numerous industrial businesses in the area, while other economic sectors include agriculture and viticulture. Fa-mous wines such as Bardolino, Valpo-licella and Prosecco mature in the region's hills, while corn, wheat, pota-toes and rice are cultivated in the valleys. The textile industry is repre-sented by brands such as Diesel and Replay, and, like other industrial sites in Veneto, is concentrated mainly around Vicenza and Verona.

All three branches of Viessmann Italy have their headquarters in Verona.

The Arena in Verona has been used for concerts

during the summer months for more than 100 years. Rock concerts take place there as well as the annual opera festival.

The oldest bridge in Verona is the Ponte Pietro, built in 100 B.C. and a symbol of the city.

The successful series of Viessmann technical forums, which have al-

ready drawn several thousand visitors, has gained a further event format: The first Wood Energy Forum took place in the information center of the Viessmann Academy in Allendorf (Eder). On the first day, well-known experts considered the fuel source from different perspectives, and on day two it was possible to take part in in-depth seminars. Around 200 visitors took up the invitation to come to Allendorf.

Future prospects forwood combustion systemsAfter the welcome address by Prof. Dr. Martin Viessmann, Ullrich Ruwier, Division Head of Wood Combustion Technology/CHP, opened the forum. The Managing Director of Viessmann Holzheiztechnik GmbH, Christian Rubin, then outlined future prospects for wood combustion systems.

First Viessmann Wood Energy ForumA new format within the successful series of events

1st German Federal Emission Control Act and market incentive program (MAP)The current market situation for modern wood boilers was analyzed by Dr. Lothar Breidenbach, Managing Director of Technology in the Federal Association of Germany, House, Energy and Environ-mental Technology (BDH). The effects of the second stage of the 1st German Federal Emission Control Act on the market for pellet boilers were discussed by Martin Bentele, Managing Director of the German Energy Wood and Pellet As-sociation. Finally, Werner Leidig, Head of the MAP in the German Federal Office of Economics and Export Control (BAFA), presented the new market in-centive program and its potential effects on the wood energy industry.

Explanation of the new VDI guidelineA new guideline from the Association of German Engineers (VDI) concerns the storage of wood pellets. Martin

Behr, Second Chairman of the Board of the German Energy Wood and Pellet Association, explained the details. The lecture by Dr. Daniel Kuptz from the Technology and Support Center in Straubing (TFZ) was about the fuel quality of woodchips, and, in particular, about standardization, certification and recommendations for use.

Innovations from the ViessmannHolzheiztechnik GmbHFollowing this was another lecture on the 1st German Federal Emission Control Act. Herbert Wazula, the Techni-cal Regional Trade Supervisor of the Federal Association of Chimney Sweeps (ZIV), explained the demands arising from this with regard to inter-pretation and monitoring in practice.

Market partners of the Viessmann group traveled together to

Japan. Together with Markus Dönges, Manager of Product Sales Manage-ment Viessmann Deutschland GmbH, and Bram Peters, Manager of Product Management Viessmann Allendorf GmbH, they visited the headquarters of the Viessmann fuel cell partner Panasonic in Kadoma. The fuel cell module developed there has already been put to use more than 80,000 times in Japan. Viessmann adapted it to European requirements and inte-grated it into the first mass-produced fuel cell unit in the world, Vitovalor 300-P. The partners on the trip have already installed many of these appliances with their heating com-panies.

More independence of thepublic power supplyVitovalor 300-P was launched on the European market a year ago. In com-parison with a gas condensing boiler and purchase of mains electricity, a micro CHP system saves up to 40 per-cent energy costs and reduces CO2 emissions by around 50 percent. Up to 15 kWh of electricity are produced on a daily basis, which mostly covers

As the only compact hybrid device on the mar-ket, Vitolacaldens 222-F combines the high effi-ciency of oil condensing technology with the use of free ambient heat. It is categorized in the top efficiency class with a rating of A++.

21

O il and gas will still play an import-ant role in building heating

systems for a good many years yet. However, many homeowners are ask-ing themselves whether they should opt for a fossil fuel or a renewable fuel source when modernizing their systems. The newly developed hybrid devices use both renewable and fossil fuels. The latest device range offers a suitable solution for every situation.

Respond flexibly to trends on the energy marketIntegrating a condensing boiler, heat pump and highly efficient energy management system, this unit can alternate between heating with gas or oil or with electricity and free heat from the outside air. Homeowners thus do not need to decide on a particular fuel when they acquire a system. This allows them to respond flexibly to trends on the energy market, making heating sustainable. Moreover, these units are already equipped to adjust to future price signals from power supply companies.

Hybrid Pro Control controls theenergy mix Intelligent control with Hybrid Pro Con-trol automatically optimizes operation of both heat generating modules, de-pending on energy prices and the outside temperature. The owner can decide whether heating should operate in ecological or economical mode. The controls activate the heat generator module for whichever fuel can currently be used most economically, thus always achieving the lowest emissions or heating costs.

Renewable, sustainable and highly efficientHybrid device range for oil, gas, electricity and ambient heat

Vitolacaldens 222-FVitocaldens 222-F is the only compact device on the market to unite the high efficiency of oil condensing technology with the use of free ambient heat. As a result, it is rated in the top efficiency category, A++. The heat pump module covers the baseload and, consequently, the largest share of the annual heat output. The oil condensing module switches on automatically at very low outside temperatures and for peak demand at short notice. The integrated drinking water primary cylinder guaran-tees great DHW convenience at all times.

Vitocaldens 222-FThe counterpart to the oil hybrid unit is the gas hybrid device Vitocaldens 222-F. Flexibly used with gas and ambient heat, it is also classified in the top effi-ciency class with an A++ rating. This model also integrates a primary cylinder.

Vitocal 250-SThe wall-mounted hybrid device Vitocal 250-S offers the ideal solution for a flexible combination between gas or oil boilers, custom-designed DHW cylinders, and a heat pump unit. Connection to floor-standing or wall-mounted boilers up to 30 kilowatts and DHW cylinders could not be simpler. The complete hydraulic system and all electrical components are preinstalled in the air/water heat pump internal unit. Controlling with Hybrid Pro Control ensures optimum, sustainable use of both heat generators. Vitocal 250-S even allows existing systems to be retrofit, ensuring that they meet the latest technical standards. The unit achieves efficiency rating A++.

Rising electricity prices make inex -pensive power from micro CHP and photovoltaic systems increasingly at-tractive. The Vitovolt electricity storage system can improve the benefits and cost effectiveness of such systems significantly. It stores self-generated electrical energy not currently needed, ready for use at a later stage, reducing the need to purchase expensive grid power. If the public power supply should fail, this system can allow you to operate the micro CHP unit, con-sequently ensuring power and heat supply in the building. Off-grid network operation is also possible in buildings without a mains connection, such as holiday homes.

Lithium-ion cells provide up to 5,000 charging cycles and a lifespan of up to 20 years. With a capacity of 5.5 kWh,

Mammut Sports Group AG is one of the most renowned

manufacturers of outdoor equipment. With customers who enjoy being close to nature, Mammut also attaches great importance to maximum efficiency and the use of renewable energies for the heat supply to its buildings.

150,000 cubic meters of interior spaceMammut's new logistics center for Europe on the A7 Autobahn in Memmingen, Germany, first im-presses merely due to its size, equal to one and a half football fields. More than 100 employees manage supplies for retailers and the compa-ny's own flagship stores from here. Although most of the interior space of some 150,000 cubic meters is taken up by a fully automated high bay shelve warehouse, the offices, showroom, and Shipping Department also need to be supplied with heating and hot water.

Three brine/water heat pumpsAlois Müller, the Memmingen-based contractor installed three Viessmann heat pumps (Vitocal 300-G Pro, Vitocal 300-G) with a total heat output of 450 kW. The heat pumps use groundwater as their heat source. They

draw the heat contained in the ground-water from wells up to 60 meters deep and increase it to a flow temperature of 50 degrees Celsius.

Heat distribution via ceilings and floorsThe heat is channeled into rooms in different ways: the showroom and other facilities on the first floor have floor heating. Radiant ceiling panels keep things warm in the extensive spaces in Order Picking and Shipping while a ventilation system in the suspended ceiling supplies the offices.

Highly efficient and economicalLarge window surfaces in the offices use the incident solar energy in winter. In summer, electricity is only required to operate the pumps to circulate the cold groundwater to cool the build-ing to a pleasant temperature. Energy-efficient structural components help to ensure that only the small Vitocal 300-G with an output of 28 kW is needed to supply heat to the office area in spring and fall.

The entrance building of the Schwarzwald-Baar Clinic in Villingen-

Schwenningen is what is known in the world of architecture as an "eye-catcher": The bright colors of the logo are repeated in the design of the facade, and a huge steel structure more than 42 meters long, made by the artist Robert Schad, towers above the top corner of the building. The hospital's energy center is no less impressive with its three distinctive chimneys. Viessmann technology pro-vides a reliable supply of heat and steam to the hospital.

Efficient, reliable supply of heat and steamAutomatic control of all heat generators in the Schwarzwald-Baar hospital using individual heat meters

Domestic fuel for heat generationA baseload hot water and heating sys-tem is provided by a Vitoflex 300-FSR biomass boiler. The boiler is equipped with a hydraulically operated flat mov-ing grate. The necessary woodchips are sourced locally.

In addition, there are two gas-driven Vitomax 200-LW appliances to cover the required peak loads. The heat gener-ators are decoupled from the heating network via a heating water buffer cyl-inder. It stores the heat not currently needed. Depending on the outside

temperature, the flow temperature lies between 75 and 85 degrees centi-grade.

Pure steam for sterilizationHigh-pressure steam at 10 bar is needed for the cleaning machines, for the conveyor belt washer for sterilizing medical instruments, for the central kitchen and to humidify the rooms. This is provided by another Viessmann biomass boiler, Vitoflex 300-FSR with 1.6t/h, and, if required, the gas-fired high-pressure steam boiler Vitomax 200-HS is also available.

Eye-catching: A 42-meter-long steel structure by the artist Robert Schad dominates the entrance to the Schwarzwald-Baar Clinic.

PRACTICE

Heat meters control the heat generatorsThe whole energy system is load- dependent and runs automatically via heat meters that take into account the charge state in the heating water buffer cylinders.

Exhaust gas heat exchangers increase the rate of utilization The biomass boilers and the Vitomax boilers have downstream exhaust gas heat exchangers (Economisers). They increase the rate of utilization while at the same time reducing energy con-sumption and so also energy costs.

The Schwarzwald-Baar hospitalThe Schwarzwald-Baar hospital is a teaching hospital for the Univer-sity of Freiburg. With a capacity of 1,000 beds at two sites in Villingen-Schwenningen, it is one of the big central care providers in southern Baden-Wuerttemberg.

2,900 members of staff care for 50,000 inpatients and 140,000 outpatients per year. This makes it one of the 80 largest hospitals in Germany. 25 specialized depart-ments work at a mostly university-standard medical level and offer a wide range of services.

Model winery relies on highly efficient heating technologyA heat pump cascade supplies the winery with heat and hot water

The wine-growing Vallagarina Valley lies in the region of

Trentino in South Tyrol, very close to Lake Garda. It is home to the winery Mori Colli Zugna, founded in the 1960's. The management team wanted to ensure the economic success of the business by building a new winery with advanced technical fit-tings for wine production and heating.

Mainly undergroundIn 2010, the new "Cantina" went into operation and was the largest underground winery in Trentino. The

new building lies in a secluded place between the wine terraces of the Trentino Alpine foothills. Only about 1,500 cubic meters of the building's total volume of around 100,000 cubic meters are visible above the ground. Most of the winery is situated underneath the earth's surface and is covered by vines. On the inside there is sufficient room to store grapes from the 580 hectares of vineyards and up to 100,000 hectoliters of wine. All the processes of wine production take place here, including filling the bottles.

Competitive thanks to efficient heating technologyIn order to remain competitive in the fu-ture, the costs arising from the need for large amounts of thermal heat and hot water have to be kept as low as possible. Viessmann's highly efficient heating technology was therefore se-lected for use. Two Vitocal 300-G heat pumps working in a cascade supply the winery with free heat from under the ground. Peak loads are covered by a Vitoplex 100 gas-driven low tempera-ture boiler with up to 400 kilowatt thermal output.

PRACTICE

The new winery of the wine collective Mori Colli Zugna fits harmoniously into the land-scape of the Vallagarina valley. The building has been mostly constructed underground.

Two heat pumps, connected in a cascade, of the type Vitocal 300-G supply the winery with free heat from under the ground (below). The low temperature boiler Vitoplex 100 can deal with peak loads (left picture).

The winery

Mori Colli Zugna is one of the best known wineries in the region of Trentino in South Tyrol. The vine-yards are mainly situated along the Adige valley where there is a Medi-terranean climate. The winery's products have won numerous prizes and awards in the course of recent years and decades.

Today, almost 700 collective members are active on behalf of Mori Colli Zugna. The whole grow-ing area is about 700 hectares in size and stretches from the valley bottom up to a height of 1,000 meters in Corniano in Grestatal. The main grape varieties grown there are Pinot grigio, Lagrein, Marzemino, and Teroldego.

SPORT

Delighted to have received the "Goldene Henne" public choice prize: Franziska Preuß, world biathlon relay champion and runner-up world champion in the mass start race.

Anybody who thinks that winter sport athletes have plenty of

time for holidays and hobbies in the summer is completely wrong. Indeed, in the warm months of the year, they have to train, train, and train again. Be-tween the training sessions, however, the Viessmann Team athletes still manage to find time for an occasional adventure.

Laura Dahlmeier, a passionate rock-climber, likes to head off into the mountains every summer. This year, the runner-up world champion in the pursuit event mastered what she described as an "outdoor training special" challenge on the 4,478-meter high Matterhorn. And ski jumper Karl Geiger has now started to soar through the air in his free time as well – he is currently learning to paraglide. "aktuell" asked the two Viessmann Team athletes about their leisure activities.

"aktuell": You both do hobbies that require quite some courage, skill and concentration. Do you also benefit from these hobbies in your professional capacity as athletes?

Laura Dahlmeier: Climbing provides a great workout for the entire body and mental training. More than anything, I escape from the humdrum of everyday life when climbing. It's an ideal change for me.

Karl Geiger: My main interest in para-gliding is the balance it provides to my day-to-day life, too. However, I have also learned quite a lot of things in para-gliding theory that apply to ski jumping: for example about aerodynamics and meteorology.

Getting ready for the competitionsAn interview with Laura Dahlmeier and Karl Geiger

Franziska Preuß from the Viessmann Team was handed the "Goldene Henne" prize by entertainer Kim Fisher for the "Rising star of the year" category. "In-credible, I can hardly believe it," en-thused the world champion in the biathlon relay event and runner-up world champion in the mass start race. The German "Goldene Henne" public choice and media prize is awarded by the broadcasters Mitteldeutscher Rundfunk, Rundfunk Berlin-Branden-burg, and the magazine "Super Illu". The award ceremony was held in the Berlin Velodrom this year.

"aktuell": Do you have favorite places where you go to do leisure sport?

Karl Geiger: I don't have to go far at all. The Allgäu Alps provide a fascinating backdrop for paragliding. I can give my thoughts free rein there and afterwards devote all of my energy to concentrat-ing on ski jumping.

Laura Dahlmeier: It's the same with me. Oberreintal in the Wetterstein

"Rising star of the year" – Franziska Preuß awarded "Goldene Henne" prize

mountains near to where I live is a great spot for climbing. I also found the Yosemite Valley in the USA very impres-sive.

"aktuell": As professional athletes, you don't have much leisure time. Never-theless, do you find time for any other hobbies?

Laura Dahlmeier: My life revolves al-most entirely around sports. Although biathlon is obviously my biggest prior-ity, when I find time, I go up into the mountains. Mountain climbing is more than a hobby for me; it's a life philos-ophy. Which is why I'm actively in-volved in the Garmisch-Partenkirchen mountain rescue service.

Karl Geiger: When I find time in the summer, I like to go to the lake with friends or play a round of beach volley-ball.

Thank you for the interview.

Karl Geiger loves to recharge his batteries by going paragliding in the Allgäu Alps.
