OMNEJD extractor hood

Since we have planned a low-energy house, there should be no problem with the exhaust air...

We are torn back and forth:

OMNEJD Dunstabzugshaube
- Optics TOP
- Performance OK
- Price well

BOSCH DIB097A50
- Optics OK
- Performance fits
- Price OK

A difference of 10 dB is approximately twice the loudness.

A difference of 10 dB is perceived as twice as loud, although it is difficult to say what twice as loud means and it can vary from person to person. An example: A dishwasher with 42 dB is very quiet and does not disturb even in an open kitchen. A device with 50 dB is perceived as loud and disturbing.

The best thing will be to go there again and have a rehearsal, although it is usually not as quiet there as at home...

I don't want to be a killjoy, but ... especially with low-energy houses, in the end the guy with his blower comes along, tapes the front door with a plastic sheet, installs the blower and a pressure sensor in the house. When the blower then sucks the air out of the house, a negative pressure must develop if everything is sealed tight, but this does not happen to the same extent if air enters the house through the wall box.
Then the funding can quickly come to an end.

You should clarify this better with your architect/builder beforehand.

I also have a wood stove that has an extra ventilation duct, you can forget about the subsidy... It is not a passive or low-energy house, but this should not be up for debate here either.

Then that's good for you. But in one post you had written "Niedrigenergiehaus".
