aroTHERM plus

Air-to-water heat pump

Quiet operation makes it suitable for use in densely built-up terraced housing estates
Particularly powerful – with a flow temperature of up to 75°C
Suitable for all applications
Super low GWP due to natural refrigerant

Overview

Discover a future-proof solution today that is both powerful and environmentally friendly. The new 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 can be tailored to the properties needs with a choice of indoor units.

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. Installed indoors, the uniTOWER is about the size of a fridge freezer and saves valuable space in the room where it's installed.

In the case of higher hot water demand, the aroTHERM plus can be used together with a wall-mounted hydraulic station and a wide range of accessories, including the uniSTOR heat pump cylinders and buffer tanks.

Very quiet operation

Suitable for retro fit change

Environmentally friendly

The aroTHERM plus works with the environmentally friendly R290 refrigerant, which has a particularly low global warming potential and is therefore exempt from the EU-wide F-gas regulation. In this way, you can safely use the heat pump solution over the long term.

Your customers will be interested not only in the eco-friendliness of the technology, but also in its climate-friendly energy consumption. The system can be combined with photovoltaic or solar heating systems, among others, and helps your customers to reduce their own CO2 consumption.

Efficient and economic energy consumption

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. It’s high performance also 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.
