Vaillant offers a great new model in our portfolio of air-to-water heat pumps with the introduction of the aroTHERM plus. This award-winning heat pump is the first in our range to use natural refrigerant R290. This refrigerant, commonly used in many household appliances, has a very low Global Warming Potential (GWP) that offers many advantages over refrigerants traditionally used in heat pumps.

The new aroTHERM plus heat pump has technical features for improved efficiency, as well as higher flow temperatures, so it's perfect for new and existing heating systems (including hybrid). It's also impressively quiet in operation; great for densely built-up terraced housing estates.

With a number of indoor units available to choose from the aroTHERM plus is adaptable for many different types of properties.

The uniTOWER, containing an integrated 190 litre hot water cylinder and hydraulic components, is pre-wired for fast and easy installation. With no refrigerant certification required, the connection of both the aroTHERM plus and uniTOWER modules can be completed in a single day with minimal manpower, causing little disruption for the end user.

For a more flexible solution the hydraulic module or the heat pump interface can be installed alongside our range of uniSTOR heat pump cylinders.
