    Irgendeine Idee, wie man einen solchen Kühler entlüften kann?

      You need a pipewrench and open the nut (dont know if it is the right term for that part) next to the thermostat slightly. The air is being released and when water comes you close it. I’m not a professional for that but that’s how they did it on my radiator. It’s not that difficult but you need the right tools.
      I suggest you ask the landlord.

      Just a layman’s opinion, but I think it’s just not accessible, because the niche is to small for the radiator.

      maybe it’s connected to one in the next room ? 

      or in the wall… you gotta ask the Vermieter.

      It’s not about the type of radiator.
      The valve for bleeding it should be on the top right.
      Unfortunately, whoever placed that rad there had not enough space, just look at how there is a cutout for the thermostat.

      Is it necessary to bleed the rad?
      If you live, e.g. on the third floor and there is a fourth floor above you, you might be lucky enough that air travels to your upstairs neighbor 😉

      If you turn on the rad (thermostat to 5) does the side of the rad where the thermostat sits hot, but not the upper right side, opposite the thermostat?
      If so, yes you will need to find a way to bleed it.
      If both sides get warm, you are fine.

      It doesn’t look like it has a bleed valve. You could try to loosen the union nut next to the thermostat and bleed the air that way, but that’s something you don’t want to leak, it’s not meant for frequent bleeding.

      Generally, radiators don’t require individual bleeding, but bleeding air at the system’s highest point can be sufficient. Do you have nearby, connected, radiators you could bleed more easily?

      If all fails, contact your landlord. They can also make sure that the pressure in the system is sufficient to minimize the need for bleeding.

      The bleeding port is most likely on the right hand side near the top. You will need a tool called „flacher Heizungsschlüssel“.

      I can only bleed one radiator in my flat. Have a look at your other radiators and start from there.

      on the opposite end of the radiator from where the nob is, so in your case the upper right side, from the right side you would see that there is a small socket that accepts a square bleed key (link below).
      unscrew slowly, until you hear the air running out. Have a cloth and a sponge under it as some water will come out as well, and most likely it will be old, dirty and smell bad. Once no more air comes out and only water, close it.

      The problem you have here is that there is not enough space from the right side becase the wall is 1cm away. You might need to look for a side wrench or some bent pliars to get in there.

      That is not the end line. That means you need to bleed it higher in the line. (by bleed I assume you mean trapped air.)

    11. FZ_Milkshake on

      You need a „Schnüffelstück“ an automatic bleed device (or at least it would be nice to have one in this configuration).

      You could get a Dremel in there and hollow out enough room parallel to the vent for the key to fit.
