ᐅ Rough-in installation of central ventilation system

Hello everyone,

we have decided on a central controlled residential ventilation system for our new build.

The rough installation is now complete.

We did not interfere beforehand and trusted our installer.

However, we now have a few questions to better understand the setup and would also appreciate a brief confirmation on whether the installation was carried out correctly, if it can be done this way, or if there are alternative options.

--> The system is located in the laundry room because the technical room, due to the kitchen above, was not suitable for it (according to the installer).
So, we chose to separate the ventilation system and the air-to-water heat pump.

1. Is this feasible? Can the devices still communicate with each other (important for BAFA funding)? So far, I have not seen any wired connection between the two rooms (the rough installation has been completed since yesterday evening).

Unfortunately, I don’t have a picture of the laundry room at the moment, but logically the pipes come out of the ceiling in the basement in the same arrangement.

2. How should the piping be installed? Are additional pipes laid on the floor from the respective pipe outlets, possibly together with the underfloor heating pipes? These would then connect to the respective connection points (we have ventilation outlets either at the ceiling or high up on the wall).

3. Is it necessary or usual to install 6 such pipes—and is it “no problem” if all of them run directly underneath my bed? This can be seen in the second picture, where our bed is located.

I would appreciate some brief feedback and, if possible, pictures of your controlled residential ventilation installations.

We have not dealt with the rough installation at all and would like to gather some information from other sources before discussing again with our installer.

Thanks in advance!

I was at twice 78. Did I misread that?
But even 230 have 5kW in new builds if done properly. My non-insulated older building with 260 reaches 11.

That sounds about right. 160m² (1722 sq ft) of living space plus an unheated basement.

It's good that if the basement is unheated, then the air-to-water heat pump is indeed oversized.
