An air source heat pump essentially behaves like a fridge in reverse, drawing thermal energy from the outside air and converting it to heat for distribution around your home.
Whether it’s an air to air or air to ground system you’re installing there’s always a noise aspect to this type of equipment as they require a fan and compressor to function – and are installed externally. Your local planning authority will want to ensure that your installation doesn’t cause nuisance to neighbours and will usually ask for a noise survey under British Standard 4142. This standard identifies a method for identifying if the noise generated by your air source heat pump is likely to give rise to complaint.
And as BS4142 uses the current ambient background noise of your location as its baseline for comparison there are some situations where you might have to go the extra mile in terms of acoustic treatment of the installation in order to get it through the planning process. It all depends on where you live, how much noise there is around your area, and how close the neighbours are to your air source heat pump.
So, if you’re thinking of installing an air source heat pump it’s definitely worth checking with your planning authority as to whether they require a noise survey. The survey should be carried out by a suitably qualified acoustic consultant and it’s worth shopping around as prices vary.
