Hot water: The uniTOWER /7 offers excellent hot water performance thanks to an enlarged heat exchanger with 1.9 m².

Space: This indoor unit is designed to be particularly space-saving, making it ideal for compact installations.

Magnetite separator: The integrated magnetite separator ensures efficient system maintenance and contributes to the longevity of the entire system.

Efficiency: aroTHERM plus/8.1 is Vaillant's most efficient air-to-water heat pump, with an ETAs of up to 202%.

Particularly quiet: With a noise level of only 28 dB(A) at a distance of 3 m in night mode, it is the quietest Vaillant air-to-water heat pump.

Flexibility: Thanks to the uniquely minimal protection zones, the heat pump offers maximum placement freedom, allowing it to be easily integrated into any environment.

Design: The elegant design in black-grey (RAL 7021) harmonizes perfectly with modern living concepts.

Warranty: Benefit from a free 5-year warranty.

Optimized connectivity: With the included VR 940, you are perfectly connected and can conveniently control your systems.

PV integration: The heat pump is designed for easy PV integration, with some additional hardware and/or software required to optimize your energy consumption.
