Heat pump myth 1: Heat pumps are only for heating, they’re no good for cooling

The truth: Quality heat pumps can very quiet when properly installed

They are much quieter than they used to be! Air source heat pumps have the highest noise levels as several thousand cubic meters of air have to be blown through the device daily. Thanks to constant further development, modern devices are many times quieter than 10 or 15 years ago. 


Quality matters here too: All Stiebel Eltron heat pumps have market-leading low sound emissions and come with “silent” programs that can be set for night time operation. Our compressor and electronics are encased in a sound-insulated chamber to reduce noise as much as possible. 


When using high-quality devices, correct dimensioning and careful planning of the system, sound problems are greatly reduced or even eliminated.
