Our team were over in Hereford this month for the install of this incredible air source heat pump system - the Aerona 15.5kw R290.
Built for bigger homes that need some serious heating power, the Aerona can operate in temperatures as low as -25°c, so this homeowner is well prepared for when the cold snap of English winter finally arrives. ❄️
But you might be surprised to know that the Aerona is Quiet Mark accredited, producing a sound pressure level of just 41.9db(A) at one metre - that's around the sound levels you'd experience in a quiet library! 🫢
This newer generation Grant system is big on performance. Not on noise.
