ᐅ Controlled ventilation system manufacturers – Which ones are recommended and where can you arrange the design?

Hello everyone,

Next year is the time, and we will start building.
The building permit (planning permission) will be submitted next week before the electrician begins with the conduit planning and the structural engineer starts. I have the following questions for you experts:

Key data:
"City villa" 200 sqm (2,150 sq ft)
Summer bypass
Enthalpy system

Now to my request...

We want to install the ducts for the mechanical ventilation with heat recovery ourselves and possibly have the mechanical ventilation system installed and commissioned by a professional company or dealer.

Since we have not yet decided on a heating manufacturer or specialist company and want to remain independent in this regard, we are now looking for information:

1. Which manufacturer would you recommend given the key data?
2. Should we request professional planning directly from the manufacturer or the dealer? Does anyone have an idea of the approximate costs?
3. Should everything be done through Selfio.de? Is the planning good? Has anyone gained experience there? Is the material of good quality?
4. If there are other options, please share them...

I am sure I have forgotten something, but this should be enough to start.

Best regards,
Mateo

Is there a specific reason you want to install it yourself?
I am more the type of person who says, “If something isn’t done properly, I file a complaint,” which can be difficult when you do it yourself.

Hello,
Yes, of course, the reason is the cost.
We got a quote, and I had looked up the installed device (I think it was Vallex). I believe it was just under 5000€ (about 5400 USD). The quote was just under 11,000€ (about 11,900 USD).
That’s basically why we want to do it ourselves. We will also lay the conduit pipes ourselves.

Best regards

And you’re able to do that too? I mean, install it so that the electrical currents are correct, no noise issues occur, etc.?
This isn’t meant to discourage you, but I’m genuinely interested.
Despite having skills and understanding, I wouldn’t trust myself to do that.

At the beginning, I also thought that doing something like this myself wouldn’t be difficult. We probably would have failed already at the core drilling for the pipes...

Okay, that was poorly phrased. We only want to install the pipes ourselves.

Currents, noise pollution, etc. should be avoidable through professional planning, right?
