Noise caused by heating, cause, who bears the costs for sound insulation?

Hello,

we have placed our heating circuit distributor for the ground floor, as well as the heating system (air-to-water heat pump), in a small annex outside our house, which is directly attached to our house. From this little room, the pipes for the heating circuit run directly through the wall into our guest/workroom and from there into the entire ground floor.

Now we have noticed that (only in this room) a faint noise can be heard when the heating is running. It is not really loud, but still noticeable when the room is silent.

We now need to investigate more closely with the architect and the heating engineer why the noise is transmitted to this room.

Assuming that the noise can be eliminated by various soundproofing measures and these cost money. Who then bears these costs? Does a heating engineer have to ensure that nothing can be heard or, if this was planned incorrectly, does the architect guarantee that this will be resolved? Or are there measurement values stating that the noise is not too loud and can be changed by our financial effort? Normally, I assume that with the money invested in companies and architects, you also receive a service where you do not have to say afterwards that it is not nice but acceptable...

The other heating circuits (basement and upper floor) are not audible...

Hello,

Is this annex developed as living space? And furthermore - as it is currently constructed - has it been approved by the authorities?

Kind regards

Hello,


Is this extension developed as living space? And further - as it is currently constructed - has it been approved by the authorities?

Best regards

No, the extension was not developed as living space and yes, the room was indicated by us during the new construction and also approved.

Hello,

No, the extension was not converted into living space

I thought so ...

and yes, the room was indicated by us as part of the new build and also approved.

Sorry, I expressed myself incorrectly. Is the use of the room as a utility room also specified in the building plans? And if so, did the structural engineer or whoever performed the heat demand calculation point out the necessity (e.g. noise, etc.) of converting this room into living space?

Kind regards

Well, we are building with an architect, so he knew what this room was intended for. Therefore, I assume (or rather hope) that he informed the structural engineer about this. Also, everyone else involved in our construction who has anything to do with the heating system.

But I think I expressed myself incorrectly. The heating room will ONLY be used as a heating room, the room next to it, through which the heating pipes for all the ground floor rooms run, will be used as living space. That was clear from the beginning, and I assume the architect knows that we do not want any "noise pollution" there...

....Now we have noticed that you can hear a slight noise (only in this room) when the heating is running. It is not really loud, but can be heard when the room is quiet.

This noise can have two causes: air in the system or too small pipe diameters or components that cause pressure loss. The first can be eliminated by proper venting. The latter cause excessive energy consumption for the heating circuit pump over time and are unavoidable afterwards unless the hydraulics are changed.

....Normally I assume that with the money invested in companies and architects, you also get a performance where you don’t have to say afterwards that it’s not nice but tolerable...

Absolutely right, flow noises are absolutely not acceptable long term! A well-planned system is acoustically not noticeable at all, i.e., you cannot acoustically determine whether, for example, the heating circuit pump is running or not. Have a look at your pipe network calculation, what flow velocities were planned here? Best regards
