The aroTHERM plus heat pump, can the good really get better?

The original aroTHERM plus heat pump, launched in 2020, named the gamechanger in the industry. Having been on the market for six years, we’re delighted to see that our original aroTHERM plus is still topping the heating charts and has been named “Best for Homeowners who want a strong all-round heat pump from one of the UK’s best-known heating brands.” In The Independent’s Buying a heat pump in the UK: Everything to know with top models compared.

Now six years on, technology has advanced, style has changed, and requirements of a heat pump have progressed. So, 2026 marks the launch of the remastered aroTHERM plus air source heat pump, taking the old and making it even better.

With consumers growing concerns on how noisy a heat pump is, the new improved aroTHERM plus which was launched in June this year holds the same accolade as the original - Quiet Mark. Quiet Mark is a certification that tests the noise levels of all types of products, from the home to commercial settings. Vaillant heat pumps have been Quiet Marked since 2014; in fact, we don’t just hold it, we were the first! Our heat pumps were the first ever to hold the Quiet Mark accreditation. Something here at Vaillant, we’re proud to own.
