Are they loud?
All of the ASHP units I've seen look like massive aircon units with big fans... I'm in a totally silent street where you can hear a fox fart at night... I've got a chance to think of green things like an ASHP over the next few months (already having boiler work done) but my concern is noise and vibration from the fan unit. This place being so unerringly quiet that any noise will be noticeable.

Mine is loud. The fan/air con looking bit is outside and I can hear it through the (admittedly old) double glazing. There is also a huge box about the size of an american fridge in the basement. In a few years I’d like to change it to mountain (ground) source.

I've never heard it

This is a really good point. No ASHP here and we put our boiler in a cupboard outside, but the boiler, pumps etc. send noise down the pipes which run down one side of our flat. There are two walls between them and our bedroom but they are surprisingly loud. Not a big deal but for our next place (which I want to be somewhere very quiet) I will think carefully about the location of utilities/services, how much noise they make and how to stop it spreading around the house.
Where are you that's so quiet out of interest?

I am in a modern flat, so very well insulated but my hot water is via a ASHP, room heating via convection heaters. The ASHP has been in 8 years and seems to of been problem free but it is pretty big compared to a boiler given that it only does hot water so needs an airing cupboard or loft to have the tank in that it is heating and obviously it isn't very responsive, so like growing up before combi boilers, if you all have showers and use the up the hot water, you are bang out of luck, it does have an immersion element you can flick on for an hour for such situations. I almost never have that issue as it is only two of us but can imagine a family would have issues.
