At the International Trade Fair for Sanitation and Heating (ISH) from 17 to 21 March 2025 in Frankfurt am Main, Vaillant, the global market leader for central heating systems, presented new heat pump models for new and existing buildings, digital services for installers and intelligent energy management solutions for property owners in Hall 12.1 (Booth E91).
On an area of around 650 square metres Vaillant presented its latest heat pump systems and digital services. Visitors of the Vaillant booth experienced a completely updated heat pump portfolio for new and existing buildings. In addition, Vaillant also showed a wide range of digital services for installers and end customers. The booth at the ISH was not just a showcase area, but also a space for interaction. The Vaillant team offered exciting discussion rounds, informative presentations and innovative technology.
aroTHERM perform – excellent performance in large buildings
The new aroTHERM perform air-water heat pump with a heat output of 15 and 20 kW has been developed specifically for large detached homes and apartment buildings. It is the first heat pump that has been optimised for efficient operation involving radiators. Even at temperatures well below freezing, at –15 °C, the heat pump still reaches its maximum flow temperature of 70 °C. This means that it can also be operated in extremely cold areas.
With a maximum noise level of 62 dB(A), the equivalent of a normal conversation, it is extremely quiet in this output class. Integration of the new iQconnect electronic platform allows for particularly easy cascading of up to six heat pumps as well as intuitive control via a convenient 7-inch touch display. Thanks to innovative safety features, the aroTHERM perform can be installed almost anywhere in the home with virtually no limitations. Furthermore, the heat pump has new indoor units that are even easier to install and use.
aroTHERM pro – a safe choice for numerous applications
The new aroTHERM pro heat pump is available in three output sizes: 5, 7 and 11 kW. It is particularly space-saving and can reach a flow temperature of 65 °C at an outside temperature as low as –10 °C. However, even in extremely cold weather at –25 °C, the heat pump can produce a flow temperature that provides warmth and comfort.
Like the aroTHERM perform, due to new safety features, the aroTHERM pro can be set up almost anywhere on a building, virtually without any limitations. Furthermore, the new heat pump model also has new indoor units that are even easier to install and use.
aroTHERM plus – more efficient, quieter and in a new design
The aroTHERM plus air-water heat pump – one of the best-selling heat pumps in Germany – has been substantially revised. Thanks to new indoor units, it is much easier to install and operate. With the natural refrigerant R290, the aroTHERM plus can achieve high flow temperatures, making it suitable for all weather conditions.
Also, this new generation is even quieter than its predecessor and has a newly designed outer shell. It can be installed directly next to a building with almost no limitations, thereby offering maximum flexibility, even where space is limited.
geoTHERM exclusive and geoCOMPACT exclusive – space-saving geothermal energy
The new geoTHERM exclusive and geoCOMPACT exclusive are the first indoor geothermal heat pumps from Vaillant that use the natural refrigerant R290. Thanks to an activated carbon box developed by Vaillant and the Fraunhofer Institute for Solar Energy Systems ISE, there is no need for safety precautions such as exhaust pipes or leakage sensors in the installation room. This simplifies installation and saves both space and additional costs. Moreover, both heat pumps maintain a maximum flow temperature of 75 °C for guaranteed safety in all weather conditions.
The geoTHERM exclusive and the geoCOMPACT exclusive are equipped with a cooling module, a brine filling unit, isolation valves, safety assemblies, a controller with an Internet interface, an electric heating element and a hot-water changeover valve as standard. The geoCOMPACT exclusive also includes a stainless steel hot-water storage, allowing for a particularly space-saving installation.
iQconnect - new electronic platform: easier operation, quick installation
The aroTHERM perform, geoTHERM exclusive and geoCOMPACT exclusive heat pumps are equipped with iQconnect, a completely newly developed electronic system with integrated control technology and a touch display designed for ease of use. For installers, iQconnect simplifies and speeds up the installation process, as it significantly reduces the effort required for wiring and commissioning. Installers can also access device functions in real time and install updates for new functions and optimised operation via an Internet interface. In the medium term, iQconnect will be available for all new Vaillant heat pumps.
climaVAIR plus – air-conditioning units with smart technology
The new climaVAIR plus mono and multi-split air-conditioning units combine high energy efficiency with artificial intelligence. This minimises energy consumption and regulates humidity. The new appliances are also even quieter than their predecessors.
Future-proof with a five-year warranty
Vaillant reaffirms its commitment to quality with a free five-year warranty on all new heat pump models. The extended warranty can easily be activated via the myVAILLANT app. In addition, the integrated remote support enables continuous optimisation of operating settings for maximum efficiency.
ProjectPORTAL – simplifying the day-to-day work of installers
The new ProjectPORTAL combines all digital applications for partner installers on a single platform and makes their daily work much easier. Customer projects can be managed completely digitally via this platform, from consultation to installation. Thanks to the one-off entry and permanent storage of project data, installers save valuable time in all applications used. Furthermore, if requested by the installer, Vaillant experts can be directly involved in ongoing projects and provide targeted support.
EnergyFORECAST – optimal energy consultancy
Vaillant’s proven and widely used EnergyFORECAST tool has been enhanced with a range of new features. The latest additions include self-consumption of photovoltaic electricity, an improved visualisation of CO2 emissions and costs and the integration of dynamic electricity rates. As a result, the tool offers an even more transparent presentation of the costs of different heating systems and the calculation of the respective amortisation period. At the same time, it factors in potential future price developments and current subsidy options.
EnergyPLUS helps reduce energy costs
EnergyPLUS enables heat pump owners to reduce the operating costs of their system by optimising the use of self-generated photovoltaic electricity. Thanks to the use of dynamic electricity rates, the heat pump draws its operating energy precisely when it is available at a favourable price. The energy management tool is compatible with the products of the most common photovoltaic manufacturers and electricity providers. EnergyPLUS is ready for immediate use, requiring no additional hardware.
OptimisationPLUS – reducing energy consumption
By continuously monitoring the heat pump’s operating performance with OptimisationPLUS, energy consumption can be reduced by up to 15 per cent compared to non-optimised systems, while also increasing the service life of the heating system. With OptimisationPLUS, Vaillant can automatically check the heat pump settings both quickly and easily from a remote location.
myVAILLANT Pro – easy digital system support
The enhanced myVAILLANT Pro app enables Vaillant partner installers to easily manage their customers’ heating systems from the office or while on the go. The app provides an overview of the device status, including system and parameter settings. This allows installers to optimise system efficiency remotely and plan any necessary on-site visits. Any errors that occur are automatically reported by email, with an integrated error code assistant providing detailed descriptions and diagnostic guidance. In addition, an Interactive Service Assistant (ISA) navigates the installer intuitively through the individual steps of maintenance, repair and installation of heating appliances.
At the Vaillant press conference, Dr.-Ing. Norbert Schiedeck, CEO of the Vaillant Group, spoke about the heating technology market and the strategic orientation of the Vaillant Group. Dr Tillmann von Schroeter, Managing Director of Vaillant Germany, presented the company’s new heat pump portfolio for new and existing buildings, digital services for installers and intelligent energy management to lower the operating costs of heating systems.
