We are planning our 40+ single-family house with a ground source heat pump and a ventilation system with heat recovery.
Some time ago, we visited a show home from a company that starts with "Finger" and ends with "Haus" (I'm not sure if the name can be mentioned). This show home also had a ground source heat pump with a ventilation system equipped. The air ducts for it were located on the floor, both on the ground floor and the upper floor. We already noticed the relatively loud noise from the ventilation downstairs, but when we were upstairs in a closed meeting room, it was really disturbingly loud.
I can’t quite describe it properly; it sounded like metal blowing air. Really hard to explain, but it was definitely noticeable and unpleasant.
On another occasion, we visited a show home by a company with "Streif Haus" in the name, but no extra suffix at the end. Here, however, there was a ground source heat pump with integrated ventilation. We absolutely couldn’t hear anything, not even with the door closed and my head (almost) right at the air outlet on the wall.
Actually, we have never heard the air in any of the houses; it was only noticeable in the first house mentioned.
Since we are considering the same system principle, albeit with different brands, I’m now a bit worried that it might be the same with us, and then this system would be turned off 100%, permanently! That’s simply not an option, not only when sleeping but in general.
Are there general things to consider in advance to reduce the "noise"?
Is the brand decisive?
Are the ducts included with the brand of the ventilation system, or do they generally come from somewhere else, so that one can be lucky or unlucky depending on what the builder installs?
I would appreciate your answers…
Best regards Dany250

Yes, using a general contractor (GC) from outside the region is indeed a risky move, especially because of the subcontractors. On the other hand, if the client feels confident with their GC and is practically ready to sign the contract, how useful would it be to introduce any “uncertainty” at that point?

What does that actually mean? It means that we don’t know any architects, nor do we know anyone here who might know one. We’re not from this area ourselves...
Since you keep hearing that even architects can fail, we immediately decided not to go down that route. We simply agreed that, given their volume of projects, prefab home manufacturers must know what they’re doing. Of course, over the past few months, we’ve also identified a few “talkers” and learned a bit along the way, so we’re actually quite confident that this shouldn’t be a big mistake (knock on wood and amen!!).
We also had to consider our plot of land regarding which builder would construct our dream home — and do a good job at it. Unfortunately, the location isn’t the easiest to access, so several (most) were eliminated immediately (two even declined because of this and gave us the cold shoulder), but that’s another matter.
As I said, we really feel very comfortable with our choice and hope we won’t be proven wrong. But yes, we are fully aware of the risks posed by the distance.

To make things even more complicated, one of our four remaining candidates actually lives in the neighboring town and really knows everyone and everything (he can recommend a company for almost any issue). Honestly, our gut feeling about him isn’t great (but not terrible either), even though he also “redesigned” our dream home, but he’s still in the running because he’s known these people for decades. I even joked about whether, if we don’t choose his company, he could still be hired for those kinds of tasks (since he’s also an independent sales agent). Unfortunately, he declined with a grin...

I'm curious if the air-to-water heat pump will really work!? I'll just say "24°C (75°F) all year round, please" 🙂.It will definitely work with the air-source heat pump, why not? But to maintain 24°C (75°F) every day of the year, you'll also need an air conditioning system.
