The radiator makes unbearable noises throu out the night, which drives her insane. We think that this is due to air pockets in the pipes, we can hear crackling and water drops.
The heating system is common to the whole building, and I cant turn off hot water.
How do i open this shit
What is important to say: only turn the little round bolt with the slot in it, do not screw out the whole valve.
The other comments sound really scary, does the US have another system? Why should there be steam coming out?
I don’t have first hand experience, but I think NYC and possibly some other large US cities do actually operate on a steam network. It’s not a closed loop hot water system like I have in my house, from what I understand you purchase hot steam like you would buy electricity.
Take all of that with a grain of salt until someone that knows more can chime in.
Whoa, what the hell? Id like to know more if true!
EDIT: what the actual living hell???

Fascinating, thanks
Oh, I know this!
Radiators run at different temperatures, radiators could run at around 80 C which is enough to “steam”. In my part of the world, we’ve lowered the water temperature to not scald people neither on the radiators nor if they’d start leaking. OTOH we now have more radiator surface area and insulation.
Oh valid point. Dont unscrew the whole valve haha. Only the slotted key hole!
Steam might come out if you have a very major pressure issue or water temprature is way way too high. Either case, slowly opening the valve solves all off that
