ᐅ Groundwater Heat Pumps – Noise Levels

Hello everyone!
I’m a bit undecided. I’m currently researching ground-source heat pumps and was wondering how reliable the manufacturers’ claims are regarding noise levels. For example, many suppliers advertise their models as especially quiet. Are there specific standards that define when a heat pump can be called particularly quiet, or is that mostly up to the marketing department? So far, I haven’t seen any decibel ratings. Is there any way to estimate how loud the pump might be in advance? Are newer heat pumps generally quieter, or is noise reduction not a priority in their development?

Thank you very much and best regards

I have a Geo*thing from V... The noise level and the sound itself are comparable to that of a refrigerator (which it essentially is). In the utility room/basement with a door, it is not audible elsewhere.

Thank you. If you have never experienced something like this in real life, it can be hard to judge.

But it is quite surprising how normal refrigerator noises are to us—whereas with heat pumps, I have often been made aware of the apparent noise disturbance. What the monkey doesn’t know... 😉
