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.
