Overview

The new air-to–water heat pump combines great performance, energy efficiency and sustainability, with an energy efficiency class of A+++.

In combination with the uniTOWER, the aroTHERM plus offers the best convenience for hot water – for long showers and rain shower heads. Alternative indoor units are available such as the hydraulic station and heat pump interface, for full system flexibility.

Equipped with the latest heat pump technology

Compact and super quiet

Great performance does not require a lot of space. The uniTOWER indoor unit is only about the size of a freezer and fits into a utility room. The outdoor aroTHERM plus unit also has impressively compact dimensions.

With sound power as low as 54dB(A) the aroTHERM plus 3.5, 5, 7 and 12 kW outputs have been accredited with the Quiet Mark. This system can thus be flexibly positioned, even in densely populated terraced housing estates – without any negative effects for your neighbours.

Ideal for retro-fit and new buildings

The aroTHERM plus is not just the perfect solution for new buildings, because it provides an outstanding hot water supply. It can also be used in existing buildings as an alternative to your current heating system.

*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.
