Air Source Heat Pump Noise: How Noisy Are They?

If you’re considering installing a heat pump in the UK, you probably have a lot of questions about them, like: “Are heat pumps noisy?” The short answer is that heat pumps do produce some noise, but not as much as you might think.

Heat pump noise levels vary per heat pump type. A ground source heat pump is the quietest option, whereas an air source heat pump has the highest noise levels. The noisiness of a water source heat pump is somewhere in between those two. 

For a better idea of how noisy heat pumps are, you can check the overview below:

Once your air source heat pump installation is complete, you’ll notice a low whirring sound as it operates. This occurs as the fan system of your heat pump transfers air into the compressor. 

Even though air source heat pump noise is the highest of the three heat pump options, it’s hardly noticeable. These noise levels are comparable to those of a gas boiler (40 - 60dB), an air conditioner (40 - 80dB), or a fridge (30 - 50dB). So, you shouldn’t experience any hugely disruptive noises with an air source heat pump.

As of April 2021, there are some noise regulations in place for properties with an air source heat pump in the UK. Currently, these state that the limit for air source heat pump sound emissions is 42dB measured from the nearest neighbouring home. These noise levels should not be exceeded and experienced by your neighbours. 

To be sure that you’re adhering to the heat pump noise regulations in your area, be sure to consult your local authorities.

No, generally you won’t be able to hear heat pump noise from inside the house. However, in some cases, if your window opens to the installation site, some of the noise may be carried indoors, causing some discomfort.

Even though heat pumps make some noise, in most cases, you won’t notice it unless you really listen out for it. Just like the soft hum of your fridge, which is such a normal part of day to day life that you probably don’t even notice it, your heat pump produces at most a low background noise.

To avoid noisy heat pump operation, be sure to take a look at the specifications surrounding noise when choosing your heat pump. This is primarily important when it comes to air source heat pumps.
