ᐅ What is wrong with my heating system?

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:

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

I've seen it all before...
And putting the part back in while the water fountain is coming out is not that easy.

@Specki As you correctly quoted yourself, it is about "pressing in," not pulling out with force. Please read carefully before writing. And the people here are not as inexperienced as you seem to think.

I also think the supply and return were swapped. I have a video about it somewhere, but in our case, it was the heating coil in the mechanical ventilation with heat recovery system.

If you press something in with pliers, you can just as easily pull it out again... Small cause, big effect! I have actually seen it happen live, how a few liters of heating water emptied into an apartment like a fountain because someone pulled this pin out. I just wanted to warn against that. It happens faster than you think if you’ve never done it before. And then you’re the one who ends up with the damage.

All good, on Monday the professional called by the landlord will come and fix it.
Thanks to all of you for the quick and helpful advice – really kind!
