Heating with hydrogen – innovative technology for a climate-neutral future The first gas condensing boilers and fuel cells certified to run with blends of up to 20 percent hydrogen will be coming onto the market in 2021. This makes Viessmann a leading innovator in the use of hydrogen to generate heat and power. Pages 12 / 13

New generation of heat pumps with high flow temperature With a flow temperature of up to 70 °C, Vitocal 25x-A was developed with modernisation projects in mind. You can continue using any existing radiators. With its extremely low GWP (Global Warming Potential) value of 3, the "green" refrigerant R290 (propane) these units use is especially environmentally responsible. Pages 24 / 25

Air purification and ventilation system for rooms with up to 30 people Ventilation systems have become an even hotter topic since the start of the Corona pandemic. Not only does the Vitovent 200-P ventilation unit reduce

the viral load in aerosols, it also lowers the CO2 load in closed rooms. The result is optimum indoor air quality at all times, regardless of how unusual the situation is. Pages 36 / 37

Especially slimline and compact ventilation system with heat exchanger With its low installed height of 245 mm and a maximum air flow rate of 300 m3/h, the new Vitoair FS mechanical ventilation system is particularly slimline and extremely compact. The polymer membrane of the recuperative enthalpy heat exchanger recovers heat and moisture. It also prevents the transmission of viruses, mould and bacteria. Pages 40 / 41

Our new condensing boiler for liquid fuels is "Green Fuels Ready" The new Vitoladens 300-C condensing boiler is ready to work with the FAME liquid fuels of the future. As a "Green Fuels Ready" appliance, it can also be operated with low greenhouse gas liquid energy sources. These include HVO HVO PTL BTL (hydrotreated vegetable oil), PTL (power-to-liquid) fuels and higher proportions of FAME (biodiesel) instead of fossil fuel oil. Pages 46 / 47

New CHP units are particularly compact and quiet Vitobloc 300 NG 15 and Vitobloc 300 NG 20 are the first next-generation CHP 49 dB(A) units with water-cooled synchronous generators for producing three-phase power and heating water.

Dr Markus Klausner Chief Technology Officer Viessmann Climate Solutions SE Dear fellow trade professionals and all readers of our New Developments brochure,

A crisis like the Corona pandemic is precisely the time when it is most important to continue strengthening our established partnerships and pull together virtually. Our approach to achieving this during and after ISH 2021 will be especially focused on our digital offerings – www.viessmann.live There you will find presentations of all the new developments in our integrated range of solutions that are at least as comprehensive as in this brochure. For you, our trade partner friends, we will be bringing a wide range of new products onto the market that you and many of your colleagues played a decisive role in developing. First and foremost, I would like to highlight our new generation of heat pumps. Another new feature is the innovative electronic platform in our heat pumps, which is based on the electronic platform launched in 2019 for our gas condensing boilers, and which seamlessly links our ViCare and Vitoguide digital services with the new Viessmann Energy Management. This new electronic platform is also helping us continue consistently along the path from product to solution. For example, via simplified options for creating systems with heat pumps, ventilation, photovoltaic, power storage units and, if applicable, existing heat generators.

Our innovations involving the use of the new hydrogen (H2) energy source are particularly noteworthy. The growing use of this type of fuel in the very near future will be a significant step towards decarbonising the heating market. Our Vitodens gas condensing boilers are already certified for operation with blends of up to 20 percent hydrogen in the natural gas. With new "H2 ready" fuel cells, combined heat and power units and gas condensing boilers for commercial use, we offer a comprehensive product portfolio for detached houses, apartment buildings, businesses and municipalities. Our Vitomax industrial boilers are already able to utilise 100 percent hydrogen as their energy source.

Added to this are innovative ventilation systems and numerous new functionalities in digital services, such as Vitoguide, our most important digital tool for our partners. With the incorporation of the ViStart app and the Service Assistant into Vitoguide, you now need only this one tool, which runs on mobile devices with iOS and Android, for commissioning, service, maintenance and system monitoring. A number of additional functions now make Vitoguide even more powerful. These include access to advanced parameters and data trending to optimise system operation.

"Co-create climate for life" is our trade fair motto this year. As a solution provider for all living spaces, Viessmann has the right products, platforms, digital services and value added services to tackle global warming – together as one big family, one team – with you, our partners in the trade. I hope that I have whetted your curiosity with regard to our latest products, and that you will enjoy learning about the new developments in Viessmann's integrated range of solutions.

H2 Hydrogen

H2O Water

Renewable electricity Water electrolysis Combustion Heat of hydrogen and air

Green hydrogen cycle: using renewable electricity, the electrolyser produces hydrogen (H2) and oxygen (O2) from water (H2O). H2 ready heating appliances burn hydrogen highly efficiently, producing water again in addition to heat for heating, and completing the cycle.

Into a climate-friendly future with hydrogen!

The use of hydrogen (H2) in the energy sector is considered a major contribution towards achieving a successful energy transition. H2 is produced from water by electrolysis. The electricity required for this comes from wind power and photovoltaic systems.

Hydrogen _ is not toxic, corrosive or radioactive, _ does not contaminate water, and does not cause damage to nature or the environment,

_ does not produce any climate-damaging CO2 during combustion.

Its increasing importance is clearly reflected in numerous political initiatives. These include the German government's National Hydrogen Strategy, the EU Commission's "Hydrogen Strategy for a climate-neutral Europe" and the

"European Clean Hydrogen Alliance", along with a variety of H2 strategies being pursued by the federal states.

With systems that can use up to 100 percent hydrogen and fuel cell heating appliances, Viessmann is a leading innovator in the use of this new energy source. Maximilian Viessmann is a member of the German government's National Hydrogen Council. Heating with hydrogen: Innovative condensing technology for a climate-neutral future

Germany has a goal of becoming just 20 percent hydrogen to natural condensing boilers of the Vitodens climate-neutral and reducing CO2 gas would reduce greenhouse gas 3xx and Vitodens 2xx families can be emissions to zero by 2050. This can emissions by around seven percent operated with 20 percent hydrogen only be achieved if the burning of per year. content in the natural gas without any fossil fuels such as oil and natural gas problems.

Improvements suggested by trade partners have been integrated into the new Vitocell DHW cylinders. Even large DHW cylinders with a capacity of up to 300 litres can now be easily installed by just one person.

New packaging simplifies transport The secret lies in the rounded base ring which forms part of the transport packaging. This makes it much easier to transfer the cylinder from the pallet – by tilting the Vitocell, with the base ring still attached, and rolling it to the installation site.

The ring is then removed by tilting the cylinder slightly sideways. In the past, the base of the cylinder could easily become damaged or dented by incorrect handling.

Easy installation of sensors Up to three sensors, thermometers or temperature controllers can be Vitocell DHW cylinders mounted on the DHW cylinders with 46 to 2000 litre cylinder capacity no need for any tools. The usual sensor wells have been replaced by a special clamping device which guarantees very precise temperature capture.

With Vitomax, its modular range of industrial/commercial boilers, Viessmann offers reliable complete solutions for complex boiler rooms. Futureproof accessories guarantee safe operation of the systems and financial added value.

The design of these industrial/ commercial boilers also focuses strongly on reducing greenhouse gases and moving from fossil fuels to alternative, environmentally responsible

solutions. Vitomax low NOx boilers are perfectly engineered for low emission combustion processes. They can meet even the most demanding requirements 3 of less than 30 mg/m NOx.

However, the Vitomax low NOx versions are not the only boilers to offer reduced emissions. Purely electric and hybrid boilers also offer new benefits in this regard.

Hybrid or Vitomax HS/E 100 percent electric Electric boiler Vitomax boilers are designed for either fully electric operation or hybrid operation with a combination of a pressure-jet burner and electric heating cartridges.

By using electricity, operators can profit from low tariffs available on the electricity market at certain times of

day. This also reduces CO2 emissions, since electric boilers produce zero (operational/local) emissions.

Versions for alternative fuels or waste heat are also becoming increasingly

important – particularly hydrogen (H2). It is regarded as one of the most promising fuel types for reaching Hydrogen fuelled steam boiler – current climate goals. system installed at National Chlorine Industries (NCI) in Jordan, which manufactures chlorine for the Even better for the chemical industry and water treatment projects environment with hydrogen In chemical operations such as the manufacture of chlorine and other industrial processes, most of the hydrogen gas is not used and is released into the atmosphere. Vitomax boilers, which can run on 100 percent hydrogen, offer a cost effective and efficient solution, while VITOMAX

at the same time preventing a large quantity of climate-damaging CO2 emissions.

The versatile range of applications for Vitomax boilers is further demonstrated by the fact that they can also easily handle biogases and bio-oils. 5

Waste heat boilers that soon pay for themselves Waste heat boilers utilise hot flue gases or exhaust air from combustion processes to generate saturated steam or to heat water. The industrial/ commercial boilers come in two 3 versions: waste heat or hybrid. Waste heat boilers without auxiliary combustion use 100 percent of the flue gases/exhaust air to generate 1 saturated steam or hot water. 2 Hybrid waste heat boilers, on the other 4 hand, have a boiler with a burner plus 2 additional passes for utilising waste heat. Due to economic and statutory requirements, they are frequently used VITOMAX in conjunction with gas turbines and combined heat and power units.
