Vaillant has revealed its all-new aroTHERM plus – the latest evolution of its flagship R290 air source heat pump, said to represent a significant leap forward from its predecessor.

The updated model includes changes to efficiency, sound levels, installation options, controls and exterior design compared with the previous version.

Key updates

  • Efficiency: The new aroTHERM plus has CoP ratings of up to 5.39.
  • Noise levels: The unit includes Vaillant’s Sound Safe System and operates from 44 dB(A), depending on the model and operating conditions.
  • Installation flexibility: A new flexible safety function allows the unit to be installed in a wider range of locations around a property compared with the previous generation.
  • Design: The unit is now available in an anthracite finish.
  • Controls: The system includes a new semi-touchscreen interface for system setup and operation.
  • Warranty: Installations registered through Vaillant’s myREWARDS platform can receive up to a seven-year guarantee when installed with a Vaillant uniSTOR high recovery cylinder.

Mark Wilkins, technology and solutions portfolio director at Vaillant, says 

“The aroTHERM plus has always been our most popular model, but we knew we could make it even better. By combining quiet operation, greater installation flexibility, contemporary design, and intuitive controls, we’ve created a second-generation solution that gives installers a genuine competitive edge. We have been committed to leading the market with continuous innovation, and this latest addition to the range demonstrates that we are always looking for those small refinements that will make a real difference to both the installer and the end user.”

The new aroTHERM plus will be available for pre-order from June and through merchants from July.
