Discover Vaillant’s aroTHERM plus air source heat pump system. The aroTHERM plus uses the natural refrigerant, R290 to achieve higher flow temperatures of up to 75°C. Suitable for all applications, this air source heat pump can use existing radiators and operates down to -25°C.

The aroTHERM plus provides a powerful yet efficient heating and hot water system that is suitable for many types of properties. Depending on the customer's requirements, there is a selection of indoor units available.

The uniTOWER is an integrated 190 litre cylinder with hydraulic components which can easily provide sufficient hot water for the needs of a family of five, including the use of rain showers. Thanks to its space-saving dimensions, the system is the perfect choice for new buildings. The uniTOWER is about the size of a fridge freezer and saves valuable space in the room where it's installed.

If your customer has a high hot water demand, the aroTHERM plus can be used together with a wall-mounted hydraulic station and a wide range of accessories. This includes the uniSTOR heat pump cylinders and buffer tanks.

Environmentally friendly

The aroTHERM plus utilises R290 refrigerant, which has a low global warming potential, making it an ideal option for long-term use.Our customers will be drawn to the efficiency and cost effectiveness of heat pump technology. This system can be integrated with solar or photovoltaic heating systems, allowing them to lower their carbon footprint.

Efficient and economic energy

With a SCoP up to 5.03, the aroTHERM plus is highly efficient. The system delivers up to 25% more hot water and can be used with rain showers. Due to its high performance, this makes the aroTHERM plus particularly economical. Testing has seen up to a 43% saving when replacing oil or LPG heaters in retrofit projects.

*The achieved or achievable energy savings depend on various factors (e.g. local electricity prices, previous model, heating setting, use, location, outdoor temperature) and may thus vary.
