Increasing the use of heat pumps following the release of the Future Homes Standard consultation may create acoustic problems that need to be planned.
Compressor and heat pump fans cause the main noise and vibration concerns.
As air source heat pumps (whether for individual homes or part of a heat network) are typically externally located, there is the potential to create noise nuisance in and around the building, disrupting residents. Careful attention will be given to the position of the plant in relation to noise-sensitive receptors and equipment attenuation means.
A BS4142:2014′ Methods for rating and assessing industrial and commercial sound ‘ assessments should be performed to ensure the plant does not impact the external background noise levels. Heat pumps can generate 60dB. Attenuation measures could include installing silencers and enclosing the ventilation heat pump with sound-absorbing panels and acoustic louvres. These add costs and require additional space, either in plan area or vertical height.
