Hello everyone!

A few days ago, we moved into a new apartment and have been experiencing recurring issues with a radiator, for which I have not yet found a solution. I would appreciate any advice or help from anyone familiar with this.

To keep the description brief, here is a short video:

[MEDIA=vimeo]386012344[/MEDIA]

What’s happening: The radiator makes a loud, creaking noise after it has been running for some time, occurring quite irregularly, mostly around setting 3, sometimes also at about 2.5. The noise decreases if you gently press or slightly adjust the thermostat valve (see video).

As far as I can tell, the heating system is well bled. I also swapped the thermostat valve with the one on the radiator next to it as a test; the problem still occurs on this radiator, while the other one continues to work without issues. So it doesn’t seem to be a problem with the thermostat valve itself.

Is there anything I can do about this? Has anyone experienced similar problems? Or will I have to call the heating engineer?

Many thanks and best regards

Carlo

If it is an apartment in terms of rental, I would definitely contact the landlord. I haven’t heard of anything like that before; it sounds like something from a haunted house ride.

It seems to be the radiator valve (not the thermostat head). If you remove the thermostat, you will see a metal pin. You can press it in (with pliers or something similar) and move it a few times. If that doesn’t help, only a plumber can replace the valve. Since it looks like a rental apartment, your landlord needs to arrange this.

Hello

The supply and return lines were swapped.

WARNING!
Don’t attempt this if you don’t know what you’re doing!
If you accidentally pull the metal pin out, heating water will spray out. If you haven’t isolated the radiator from the system beforehand, this could be many liters, causing your heating system to drain significantly and leaving unpleasant, dirty water in your home.

It’s better to call a professional or have your landlord arrange for one.

Sorry, but I don’t understand how such advice can be given to an apparent amateur here!

Pushing the metal pin in and out is daily practice in thousands of apartments. It often gets stuck, especially in older systems.
I didn’t even know it could be removed at all. You’d need a real brute to pull it out...
