ᐅ Technical room in the attic, issues with soundproofing?

Even with mechanical ventilation with heat recovery, people can ventilate however they like. Using the window in a tilted-open position continuously doesn’t make sense because it leads to significant energy (heat) loss. But this isn’t really related to the ventilation system itself.
For us, nothing beats mechanical ventilation with heat recovery. Always fresh air (which you simply can’t achieve in new buildings by just opening windows), especially very comfortable during pollen season.

I am fully aware of the advantages, and of course leaving windows tilted open all the time is really a bad idea. But what’s the use of all that if, during a family discussion, it turns out that, for example, the beloved one feels disgusted by mechanical ventilation with heat recovery and doesn’t want to give up constantly opening the windows? Should one then change the partner? And put “mechanical ventilation with heat recovery” under desired preferences in the next dating profile?

Most people I know who are involved in house construction and building services find ventilation systems really terrible; they prefer to ventilate normally by opening windows.

Oh dear. Haven’t people been told that they can still do that anyway?

I have exactly the opposite impression.

Most people I know with controlled residential ventilation don’t want to give it up and are glad they no longer have to open windows to maintain ventilation intervals.

Those who can’t handle it often have other serious problems in their home.

Which one do you mean? He has more than one available.

It helps to explain that there is no reason for disgust, and that it is usually just fear of the unknown. The person can still open the windows if they want to.

I have his book "A Custom Architect-Designed House at a Fixed Price." Of course, it is no longer up to date since he discontinued his own construction company, but it contains some very valuable fundamental ideas that are definitely worth reading.

Regarding mechanical ventilation with heat recovery: when people flat-out reject it, no amount of argument will change their minds. This is similar in many other areas of life. People simply have their fixed opinions. That said, I am still not sure whether the benefits of mechanical ventilation with heat recovery ultimately outweigh the drawbacks, or if it might become more of a problem in the long run.

Sure, but that has nothing to do with this case. It is still interesting because those who reject it still drive cars or use public transport and spend hours in office buildings, restaurants, and hotels without any issues.

What kind of problems?

Something homemade for the condensing boiler? Did your installer and utility company see that? Especially the latter tend to be very strict about the installation conditions of gas boilers. What do both say about accessibility? Out of curiosity: How did you run the gas line from the building entry point to the condensing boiler to comply with regulations? What does the insurance company say about this type of installation regarding water damage? Do the buffer tank and expansion vessel have drip trays? How is the heating system refill handled, is there a mains water connection in the attic?

What do you mean by "homemade"? Whether I fasten the boards myself or a professional does it, it should be the same in the end. Maybe even better.

How should the installer not have seen the "homemade" parts when he assembled the heating system and everything else?!

Accessibility is provided through the attic hatch. Or is that what you mean? Otherwise, there is significantly more space around the piping “at the unit” than in many utility rooms!

The gas line was routed from the multi-utility connection through a core drilling in the concrete ceiling, then vertically inside a wall of the room above, leading up to the attic. Of course, all copper pipes with protective coating around them.

Drip trays with drains into the house drainage system are installed for the buffer tank and expansion vessel.

Also, there is a mains water connection which I can connect to the heating system as needed (a suitable hose is on the heating unit) to refill it.

Any other questions?

On the topic of sound insulation:
A soundproof booth that is decoupled from the floor could be a good alternative to a concrete ceiling. The most important thing is that no structure-borne sound is transmitted. Ask companies that build recording studios. Everything else is relatively easy to manage.
