Are air to water heater pumps noisy?

juneg

Are these air to water heat pumps supposed to be noisy? I've a new one in and the noise off it is like being on a ferry. I'm expecting to wake up in France ! I can't imagine insulating the pipes, hot press is going to make much difference.
Should I have put it in the garage as opposed to the hot press? I'm a bit worried

It's meant to go outside I'm pretty sure

Well it's a split unit, I presume, air heat exchanger outside and compressor inside. I think most units are now single mode, all outside, plug and play.
I mean this could be a 5hp compressor, it couldn't be quiet.

Split unit yes. The tank is 300l so it's pretty big.

Post a pic of the area where it's noisy. Somebody might spot something amiss.

As mentioned post a pick, could be air in the system, could be that the unit is not level, that the outdoor unit doesn't have rubber mounts under the feet to act as a shock absorber, could be a combination of these and rigid pipework going into the back of outdoor unit rather than flexible pipe so any vibration is carried along. Or could be very sensitive hearing?!?:)

Most units tend to be quiet enough, about the same as a fridge but depending how thew are mounted can lead to noise on some. Sometimes if the are mounted directly onto a wall and no rubbers used the noise can be amplified

Was there any resolution here for the noise levels?
Ours is mounted on the wall with no pads under bedroom windows and the noise is terrible.
Builder claiming it's normal and I just have to get used to it which is absolute rubbish.
Quoting us >€1200 to take it off the wall but telling us it won't make a difference.

1200 sounds steep but the builder would have to take their cut. Id say if they do yours they will have to do everybodies.

It is a skilled job and shouldnt be touched by cowboys. Im not sure on your exact system but there could be 40 bar of pressure in the fridge gas pipes, which is completely safe provided you dont touch them. The gas is very expensive to replace and normally bad for the ozone layer. The pipework must be kept clean and dry throughout anywork and the pipes need to be dragged to vacuum circumstances to take out any water vapour. Water vapour in the refrigeration pipes can turn to ice and break all the componants of your compressor.

Saying all that 1200 is a bit steep, especially if you had a few neighbours wanting it done.

My tank is in the hot press. There was noise but they insulated everything and you wouldnt hear any noise from it. The unit outside is on the ground mounted on pads. There is no noise off it.

I would begrudgingly pay it but they are adamant that it putting it on the ground won't make a difference so I don't know what to do now. I can't comprehend how it won't help.

Why not phone the manufacturer or importer.

Is it always making noise or just sometimes.
A neighbour was driven mad by their outside unit and it turned out that it was almost always (or perhaps permanently can't quite remember) stuck in defrost mode where it goes through a cycle to clear ice from the fins.

My own is at the back so below my daughter's room. She says she often heard it but it doesn't disturb her. I've only ever heard it when I'm outside and it's a whir like a pc under strain, not a ferry.

I was emailing the manufacturer and they forwarded my email to the installer who sent a lovely response making us out be idiots who are expecting no noise at all.

When the fan turns on to heat the house or heat the water which could be a few times a day anywhere from 30 minutes to an hour each time.

Would you say it is quieter inside than it is outside?

I can hear when my attached neighbours is running and the noise from it is what I would expect from ours.

That's why I suggested phoning. Email or text always gives someone an opertunity to pass the buck or get off the hook.
Write down a list of questions. 1st one, can you send out someone who doesn't know the installer. Take a short video and ask for the email of a tech that you can send it to. Get a phone number for that tech so you can follow up. Tell them your at your wits end and your sister or whoever says you should contact Joe D if they can't sort it.
You need to get active in it. Write down a plan of action. Get talking to the right people.

My indoor unit is in the utility. I've a spare single height fridge (which isn't noisy) beside it and I don't think I've ever heard it over the noise of the fridge.

Sorry I thought you were referring to the outdoor part.

Sorry I am referring to the outside part. When it's running it's as if the noise is amplified in the house. It doesn't sound like the noise is coming from outside. It sounds like it is in the house.

Is the noise being transferred through the pipes?

God no, ours is nothing like that. I think I was in the house months before I even noticed it one day.
I can only vouch for houses in my estate which are all Daikan systems but I've never noticed the noise in any of them and I've spent quite a bit of time in a few of them as I've a few friends in the same estate.

That's doesn't sound normal too me. I've lived in houses with gas boilers and oil boilers and this is probably the quietest system I've had.
