July 08, 2026
We are proud to announce that the Windhager AeroWIN XP, AeroWIN DELUXE NXT and TerraWIN DELUXE NXT heat pumps have achieved the prestigious Quiet Mark certification, recognising their exceptional low-noise performance and reinforcing Windhager's commitment to delivering premium comfort without compromise.
The newly launched AeroWIN DELUXE NXT and TerraWIN DELUXE NXT represent the next generation of heat pump technology. Developed to combine market-leading efficiency, sustainability and acoustic performance, these advanced systems offer outstanding heating and cooling capabilities while operating at remarkably low sound levels. The AeroWIN DELUXE NXT air source heat pump is promoted as one of the world's quietest compact air-to-water heat pumps, featuring ultra-efficient R290 refrigerant technology, active cooling as standard, flow temperatures up to 72°C and SCOP ratings of up to 5.7. Similarly, the TerraWIN DELUXE NXT ground source range delivers exceptional efficiency and whisper-quiet operation, making it an ideal solution for both new-build and renovation projects.
Quiet Mark is an internationally recognised independent certification programme associated with the UK Noise Abatement Society. Products awarded the Quiet Mark have undergone rigorous assessment and are identified among the quietest available in their category. For heat pumps, certification is awarded only to models that achieve leading low-noise performance when compared on a like-for-like basis across the market.
Achieving Quiet Mark certification is particularly significant as homeowners increasingly consider not only energy efficiency and sustainability, but also the impact of sound on comfort and wellbeing. The certification provides independent reassurance that Windhager's heat pumps deliver outstanding performance while minimising noise disturbance for homeowners and their neighbours.
This recognition further strengthens Windhager's position as a premium heating technology provider, demonstrating that the AeroWIN XP, AeroWIN DELUXE NXT and TerraWIN DELUXE NXT combine cutting-edge renewable heating technology with some of the quietest operation available on the market today.
