    Was ist das für eine Maschine in Reihenhäusern?


    Wird diese Maschine im Winter zum Heizen verwendet? Sie macht ziemlich viel Lärm? Bedeutet das, dass mit meinem Strom geheizt wird?

      It’s for ventilation and for transferring heat from the warm air going out to the cold air going in. If it has started making more noise than before, I would open it to check that the air filters are clean (mine are replaced twice a year) and that there’s nothing funny going on.

      There’s usually a electric heater to warm up the incoming air even further and there’s probably a thermostat there somewhere if you want to adjust it. Your apartment also has an adjustment for the flow, mine is over the stove and has three steps.

      Iirc there’s some sort of an air filter inside. The word “air” appearing on the label also suggests that

      That’s an HVAC machine or something like that. It’s responsible for fresh air, exhaust and heat recovery of the whole apartment. Do not turn off. It indeed is natural for it to make some noise. But yeah it needs filters changed twice a year, or it will get noisier until they are changed. Ask your landlord.

      Ventilation unit with heat exchanger. Depending on the configuration, there’s a knob/control panel for controlling it somewhere close to the bathroom or it is connected to your exhaust hood in the kitchen and controlled from there.

      The speeds typically go from 1-4 or 1-5 and if you’re home you should use 2 or 3, if you have showered you should increase it for some time to help things dry. Never turn it off, but the lowest level is for when you’re away.

      Like you already know it is ventilation unit with heat recovery. I just have to add that if you hear wierd sound it could be condensation water accumulating inside.
      I used to live in a house with very similar unit and one day I heard a sound that resembles moonshine distilling.
      Turns out the bottom drain of the unit was clogged and I was greeted by a mini tsunami when I opened the ventilation unit door.
      TL;DR: if you live in a rented house do not touch it at all, let the maintenance company sort it out.
