Air-to-Water Heat PumparoTHERM perform

With a heating output of up to 20 kW and a flow temperature up to 75 °C, the aroTHERM perform is ideal for multi-family and large single-family houses as well as light commercial buildings like supermarkets or stores. For large new builds up to 1.200 m², the aroTHERM perform 20 kW is the ideal solution for efficient heating and hot water. In older buildings, modernized up to 750 m², not modernized up to 500 m², the aroTHERM perform truly shows its strengths and delivers always enough power to conveniently switch to a heat pump.

The intelligent electronic platform iQconnect takes heating to a whole new level. Recognized with the prestigious iF Design Award, iQconnect combines innovative design with advanced functionality to deliver an unparalleled user experience. Starting with simplified installation thanks to pre-integrated components such as the gateway and system controller. The commissioning assistant and large display ensure that the best settings for optimum heat pump operation are found – and kept in view. Over-the-air updates help the system stay up to date with optimisations and new features. Integrated connectivity is essential for using the myVaillant app to remotely control the system. Additional remote services for external monitoring and accessibility keep the heating system efficient and reliable all year round. iQconnect also allows the heat pump to be integrated into an energy management system, for example to use self-generated photovoltaic electricity.

The new standard in Vaillant heat pump technology: Our new safety concept allows maximum freedom for outdoor installation. Until now, air-to-water heat pumps with R290 had larger protective zones and therefore a limited choice of location. That's a thing of the past: thanks to our new Flexible Space Function, you can also install the aroTHERM perform directly next to doors, windows and cellar shafts or sockets and outdoor lighting.

Not all heat pumps can maintain a high flow temperature of 70 °C when the outside temperature drops to -15 °C—but the aroTHERM perform can. This means you don’t need a backup heater, which makes the entire system more efficient and cost-effective compared to others. Even in sub-zero conditions, our heat pump delivers consistent power output, ensuring reliable heating performance and optimal efficiency. For proof: at A-7/W55, our unit still achieves 94% of its power output and an impressive ETAs efficiency value of 151%. This capability guarantees comfort and efficiency even in the harshest winter conditions, setting our solution apart from conventional systems. In short, you get dependable high-temperature heating without compromises.

Thanks to our innovative Sound Safe System, the aroTHERM perform keeps noise to a minimum. The 20 kW unit achieves 50 dB(A) according to the ErP classification and a maximum sound power level of just 63 dB(A). That’s impressively quiet for its output and size. You can reduce the sound emission by a further 10 dB(A) by activating the night mode. Due to its quiet operation, it can be flexibly positioned meeting legal regulations.

Design that delights and performs - honored with the Red Dot and iF Design award. Our sleek and elegant design with anthracite finish and flowing lines allows for seamless integration into various architectural styles. The self-cleaning Rain Drain Design ensures surfaces stay clean and looking fresh with minimal effort. Every detail is crafted for convenience and quality, from smooth edges to easy service access. Complete the clean and modern appearance by adding the base cover accessory, which can be ordered separately.

The aroTHERM perform is powered by the natural refrigerant R290. This is not only advantageous for homeowners, but also for the environment. Its low global warming potential (GWP) of 0.02 makes it the best alternative to synthetic refrigerants with higher GWPs. The natural propane used to produce R290 is widely available, which increases security of supply.

Hot water is more than a necessity. It’s the key to comfort, safety, and well-being. In multi-family homes, maintaining strict hygiene standards and ensuring legionella protection can be challenging. But with the right solution, you don’t have to compromise. The aroTHERM perform delivers hot water that’s safe, efficient, and tailored to your needs. With flow temperatures of up to 75 °C, it ensures high hot water temperatures and a reliable legionella protection, keeping your water hygienic and safe. And unlike many systems, we achieve these temperatures without a backup heater, operating purely in heat pump mode for maximum efficiency. Even at -15 °C, the aroTHERM perform can assure cylinder temperatures of 60 °C. Whether you live in a single-family home or a multi-family building, we offer a wide range of hot water cylinder solutions to match your needs—low or high demand. With Vaillant, you get comfort, safety, and energy savings for every household.
