No, why would I bother?
Only "Blau" is from me.
As an expert and planner, I come across the most peculiar things ;-)

Hello everyone,

First, thank you for the discussion.

In another forum, I came across a study that states it is not absolutely necessary to follow the supply air and exhaust air principle strictly in a single-family house. Therefore, air circulation around doors is quite acceptable.

For this reason, I would find it very practical to place the supply air vents on the first floor as well, since I don’t see many other options. After all, these vents shouldn’t be located above the desk or bed, and the rooms aren’t very large. The only exhaust vent I would position above the toilet in the bathroom.

Any concerns from your side? Unfortunately, I’m under pressure and have to make a final decision by around 3:00 PM today.

Thanks and regards,
Robert

A supply air vent above a bed or desk doesn’t cause any issues. In our case, there is a supply air vent in the ceiling above the bed. With a room height of 2.50 meters (8 feet 2 inches), you don’t feel anything at all. I can feel a slight air movement only within about 10 cm (4 inches) around the vent; beyond that, the airflows are so slow that they are not noticeable. Since the ducts run in the ceiling cavity, you should have complete freedom to position the supply and exhaust air vents as you wish.

According to Helios' planning manual, the valves should not be positioned directly above a bed. What type of valves have you installed, please?

Round with a plate in the middle – no idea what they are called.
