Viessmann UK - Experts & Thought Leaders

Viessmann Climate Solutions has supplied 19 heat pumps to FC Bayern Munich’s Allianz Arena. The Vitocal 350 HT-PRO heat pumps are responsible for the decentralized heat supply to the entire stadium, ensuring, for example, that the bistro, fan shop and the ‘Experience World’ areas are kept at a comfortable temperature for the club’s thousands of fans. In addition, the roofs of the visitor control areas have been equipped with around 1,050 photovoltaic modules to further increase energy self-sufficiency at the Allianz Arena. Allianz Arena with state-of-the-art Viessmann Climate Solutions is part of Carrier Corporation, pioneer in intelligent climate and energy solutions. This is the latest step in a plan to gradually upgrade the Allianz Arena with state-of-the-art, renewable climate solutions from Viessmann Climate Solutions and Carrier Global and to reduce CO₂ emissions by up to 40 percent. Three large heat pumps from Carrier were installed in 2022 to supply the soccer field heating system. Air purification technology Viessmann has been a strategic partner of FC Bayern Munich since 2018, beginning as a regional partner in China before expanding its collaboration across Southeast Asia in 2021. Since the 2022/23 season, the relationship has grown into a global “Official Climate Partner” arrangement, embracing a shared commitment to sustainability. Under the deal, which runs to the end of June 2026, Viessmann provides state-of-the-art heating, cooling, ventilation, water treatment and air purification technology for FC Bayern facilities, including the FC Bayern Women’s team. Viessmann Climate Solutions The sponsorship also includes joint environmental campaigns, brand usage rights, LED board placements at the Allianz Arena, and endorsements from Thomas Müller to drive awareness of renewable and energy-efficient solutions. To accompany FC Bayern Munich’s latest new team “signings,” Viessmann Climate Solutions has developed a humorous advertising campaign, created and produced by Hamburg-based creative studio 27 km, where renowned Bayern stars demonstrate their acting talent by reacting self-deprecatingly to the confusion surrounding their “new colleagues.” 

Viessmann Climate Solutions UK has launched a new heat pump promotion, to incentivize installations of its popular Vitocal 150-A air source heat pump. For every Vitocal 150-A heat pump registered on Viessmann’s VPlus platform and installed between October 1st and December 31st 2025, Viessmann will send the installer a pre-loaded card with £150 as well as crediting the usual VPlus loyalty scheme points.

Viessmann Climate Solutions (VCS) has combined with Carrier to become the core of Carrier’s newly formed business unit Residential and Light Commercial for European, Middle East and Africa. This business unit is now able to offer brands like Carrier, Toshiba, and Beretta next to the premium brand Viessmann, thus covering additional user segments with differentiated products at various price points. Climate system technology “The climate system technology of Viessmann Climate Solutions and the cooling-focused systems of Carrier combine two core competencies that will be crucial in responding to individual customer needs worldwide,” says Thomas Heim, President, Residential & Light Commercial HVAC for Europe, Middle East, and Africa. “Carrier expands the Viessmann portfolio in the area of air conditioning and enables seamless integration of heating and cooling.” Carrier’s acquisition of Viessmann Climate Solutions There was huge media interest in Carrier’s buy of Viessmann Climate Solutions when it was revealed There was huge media interest in Carrier’s acquisition of Viessmann Climate Solutions when it was announced more than a year ago. In media interviews, Carrier Chairman & CEO David Gitlin; Max Viessmann, CEO and Member of the Executive Board of the Viessmann Group, which owned Viessmann Climate Solutions prior to Carrier’s acquisition; and Heim presented the many advantages the combination would bring. Advantages apply both to the product portfolios, which perfectly complement each other, and to the optimized development of global markets. A year later, the feedback is extremely positive, says Heim. Latest developments in the Viessmann system The sentiment was confirmed by numerous conversations with installers at the ISH 2025 trade fair in March in Frankfurt. “The advantages of this combination between Viessmann Climate Solutions and Carrier are clearly noticeable for everyone involved,” says Heim.   The latest developments were well received by the 100,000 visitors to the booth at ISH, with particular interest in the Viessmann system connecting several products into a solution based on full stack controls platform Viessmann One. Residential and commercial sector customers The alliance meets the needs of residential and commercial sector clients with a multi-brand portfolio Also at ISH, Viessman highlighted the newly created alliance of Viessmann, Carrier, Riello, and Beretta around the theme “Power Play as One Team.” The alliance meets the needs of both residential and commercial sector customers with a multi-brand portfolio of heating, ventilation and cooling solutions for all output ranges and price levels. “Together with Carrier, we are in an even better position to provide solutions that address climate challenges by reducing CO₂ emissions and increasing energy efficiency,” says Heim. Digital tools and ecosystems The expanded product line builds on the strong longstanding collaboration of Viessmann Climate solutions with installation partners. For example, the addition of (light) commercial Carrier heat pumps to the portfolio enables leveraging together existing digital tools and ecosystems with this expanded offering. “This increases the relevance of our ecosystems for both our installers and users,” says Heim. Culture of collaboration The focus from the start has been on creating a culture of collaboration among both teams When integrating companies, it is always about bringing people together and providing a framework that allows them to unlock their full potential, says Heim. Thus, the focus from the beginning has been on creating a culture of collaboration that allows the teams from both companies to contribute their unique talents and strengths. “We are convinced that we have found the right formula and that combining Carrier and Viessmann Climate Solutions will lead to 1 + 1 > 4,” he says. “To get there, our shared purpose and values play an important role in this successful integration.” Carrier product portfolios “Companies can only be successful if they think and act globally and operate in a spirit of co-creation,” says Heim. Combining the Viessmann Climate Solutions and Carrier product portfolios creates added value for all installation partners and users. The increasing complexity of the HVAC industry is contributing to a trend toward company consolidation. “Let's be honest: in the past, you simply installed a gas boiler,” says Heim. PV installation They also offer a design tool on the Internet and even financing with the help of a partner bank Heim added: “Today, it's often about heat pumps, battery storage, photovoltaics, wall boxes and an energy management system that links everything together. It's all extremely complex. That's why we are constantly training our installers and at the same time reducing their workload." "Many of our installers don't want to climb on a roof, which is fine. We then look for facilitating a service provider that adds the PV installation to the holistic offering of our partner company.” They also offer a configuration tool on the Internet and even financing with the help of a partner bank. Climate-neutral by 2050 Data centers will also play a bigger role in the future. For example, a typical office building in Manhattan requires only three cooling units, while a data center they are currently working on requires 140. An AI chip generates seven times more heat than a conventional chip. “This market is huge, and we are determined to play an important role,” says Heim. The building sector produces 40 percent of CO2 emissions in Europe. Therefore, a transformation to renewable energies is necessary to become climate-neutral by 2050. Viessmann products and systems “For us, as a manufacturer, this means that we continue to encourage the building electrification system strongly,” says Heim. Viessmann products and systems offer installers the basis for a sustainable climate solution offering for their users. Almost all areas, from single- and multi-family houses to commercial and industrial buildings and municipal facilities, can be covered by the system portfolio. New hydraulic interface Regardless of the outdoor unit (ODU), the new components always match the indoor unit (IDU) Heim highlights three notable products as part of the Viessmann System Solution. Users can now choose between the high-efficiency, high-comfort Vitocal 250-A and the more economical Vitocal 150-A domestic air source heat pumps. Regardless of the outdoor unit (ODU), the new components always match the indoor unit (IDU). This high level of flexibility pays off for the installers in significantly shorter installation times, and users only pay for what they actually need for their heating system. The new hydraulic interface also saves time during installation. Vitocharge VX3 storage unit The Vitocharge VX3 storage unit is one of the most proven battery storage units in its class. Its maximum storage capacity of 75 kWh (5 modules of 15 kWh each) is particularly suitable for large, detached houses and apartment blocks, as well as for smaller commercial applications such as supermarkets or craft businesses. Following on from the large power classes, the smaller modules can now also be cascaded at 4.6 kVA. Flexible installation options are now available, including corner or horizontal mounting, which allow for optimal adaptation to on-site conditions.

Some 38% of greenhouse gas emissions emanate from residential housing, specifically heating and cooling systems. Given the goal of ‘net-zero’ carbon emissions by 2050, new approaches have emerged to achieve that target. Some of the solutions currently being evaluated include the use of hydrogen as a replacement fuel, to store electricity from solar or wind power, or in fuel cells that use an electrochemical process combining hydrogen and oxygen to produce electrical energy and water. Hydrogen is the most abundant element in the universe, although pure hydrogen is rare on earth. It can be extracted from water (electrolysis), Alternatively, it can be extracted from natural gas using carbon capture technology to prevent carbon, a by-product, from escaping into the air. Modern terrace houses Whether hydrogen is burned for heat or passed through a fuel cell to make electricity, the only byproduct is chemically pure water. When combined with renewable energies like solar and wind power, hydrogen can be used to store energy as an alternative to batteries; unlike batteries, hydrogen gas can be stored indefinitely. FutureGrid operates three modern terrace houses with gardens in the remote hills of Cumbria Like natural gas, hydrogen is odorless. The distinctive smell currently added to natural gas could also be added to hydrogen to ensure residents quickly notice a leak. In the United Kingdom, FutureGrid operates three modern terrace houses with gardens in the remote hills of Cumbria. The houses provide a preview of a world where hydrogen has taken the place of natural gas. Yellow polyethylene pipes Engineers are testing how Britain’s natural gas pipe infrastructure can be converted from transporting fossil-fuel gas to handling hydrogen. Heating of British homes accounts for about 15% of carbon emissions, which would be eliminated with a transition to hydrogen. Hydrogen is more combustible than traditional natural gas, and its smaller molecules make it more likely to leak. There is a historical precedent for the transition in the United Kingdom. During the 1960s and 1970s, the gas industry converted from town gas (a byproduct of the distillation of coal and oil) to natural gas (mostly methane), which was discovered in the North Sea. The transition to a pipe system that can accommodate hydrogen has arguably already begun in the United Kingdom, where the gas industry is using yellow polyethylene pipes (which do not interact with hydrogen) to replace the metal pipes (prone to become brittle when exposed to hydrogen) in the country’s iron mains network. High-Volume technology Worcester Bosch has developed a hydrogen-fired boiler that could replace natural gas boilers An advantage of hydrogen is that the transition would be undetectable to consumers, who could continue to use boilers to heat their houses, although the fuel would be hydrogen rather than natural gas.  Worcester Bosch has developed a hydrogen-fired boiler that could replace natural gas boilers, but they use a hydrogen blend – 20% hydrogen and 80% natural gas. In the future, converting to all hydrogen would require an hour-long service call and only involve changing a couple of components such as the burner. Hydrogen boilers are currently a niche market; however, a regulatory change mandating their installation could make them a high-volume technology, just as natural gas boilers are today, according to the company. Heat pump technology Skeptics point to the cost of converting a country’s underground gas pipelines to hydrogen. Others suggest that a transition to energy-efficient electric heat pump technology would be simpler, and in fact is already underway. In the heat pump scenario, hydrogen could be used in a fuel cell or to store energy (from solar or wind power) in lieu of batteries. Skeptics point to the cost of converting a country’s underground gas pipelines to hydrogen The Hydrogen House in Hopewell, N.J., has been converted to run exclusively on solar and hydrogen power. Inventor Mike Strizki converted the home with a grant from the New Jersey Board of Public Utilities and using his own personal funds. It is the first solar-hydrogen residence in North America and operates completely off the grid. The only emissions are chemically pure water and medical-grade oxygen. Medical-Grade oxygen Features include a 40kw solar installation, 20kw backup power, an electrolyzer to generate hydrogen, and a hydrogen fuel cell. The home was designed to allow for the expansion of an electric and/or hydrogen refueling station. The plan is to transform the house into an interactive educational attraction with hands-on demonstrations related to clean and renewable energy. The Vitovalor 300P is a fuel cell heating appliance, made by German manufacturer Viessmann, that uses the principle of cogeneration to generate both power and heat. To do so, the fuel cell requires oxygen and hydrogen (obtained from natural gas in an earlier process). The generation of heat and power is based on an electrochemical reaction between the two elements, also called cold combustion.

New technologies continue to drive change in the HVAC market. HVAC’s image as a mature and stable industry can overshadow the high level of innovation taking place. Meeting environmental challenges and creating more cost-efficient systems are among the forces fueling the change.
