aroTHERM Split plus

The aroTHERM Split plus uses available air from the outside to heat your home and provide hot water comfort. Its high efficiency reduces your energy consumption and your carbon footprint. The setup consists of two modules: an indoor unit and an outdoor unit.

The A+++ label* is well deserved for our aroTHERM Split plus. Up to 203% energy efficiency ensures maximum comfort with low operating costs. The split technology can be used for heating, cooling and hot water preparation in newly built one family houses or energetic modernisation projects. So you are always comfortable, whenever and wherever you want.

The plus package.

With the aroTHERM Split plus, you get the usual high Vaillant quality in your home and it is a strong addition to the aroTHERM family. The refrigerant split technology offers exceptional efficiency in different capacity ranges: from 3 kW to 7kW (and 4 kW to 8 kW in southern countries with the S3 model). Let’s have a look at the advantages of the series.

Efficient performance with R32

With an energy efficiency value up to 203%, the aroTHERM Split plus is highly efficient and scores with an A+++ ErP label*. The efficiency class for DHW heating with A+ is the best in its class and keeps your operating costs low. At the same time, the tank heats up to 35% faster, ensuring hot water at all times.

Always perfectly placed

Installing the aroTHERM Split plus is just as quick as choosing the perfect location. The heat pump is installed on a house wall, in the garden or a flat roof. The indoor and outdoor units can be installed in a short time by an expert. With a distance of up to 40 m between indoor and outdoor units and a height difference of 30 m, thus also for buildings with up to eight storeys, the installation site is also flexible. This makes it easy to find the perfect location for your new heating system.

Comfort has never been quieter

The aroTHERM Split plus is one of the quietest in its class. Noise emissions are reduced to the level of a modern refrigerator. This makes the aroTHERM Split plus ideal for use in densely built-up terraced housing estates. Nothing will spoil your comfort, especially at night: In super silent night mode, the noise level is reduced to 28 dB(A) - at a distance of 4 metres from the heat pump.

Keep cool on hot days

By reversing its process, the aroTHERM Split plus also ensures the best possible comfort even in summer. The cooling function provides you with a feel-good-temperature without having to buy a separate air conditioning system.

Connectivity already onboard

The aroTHERM Split plus comes with a plug and play connectivity modul on board. This allows you to manage your heating system easily by using the myVAILLANT app.

German engineering, produced in Europe

The aroTHERM Split plus combines German engineering and extensive tests with high production standards to guarantee utmost quality and reliable operation in the long term. You can combine the heat pump perfectly together with other Vaillant components and have an even more efficient heating system from a single source.

Small size, big impact

Thanks to the new dimensions of the hydraulic tower and the modern design, the aroTHERM Split plus blends effortlessly into the existing environment. With the indoor unit you save valuable living space, especially in new buildings. Its integrated storage cylinder covers the normal requirements of a four-person family.
