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
I guess they are from US or something. Over where I live it’s not that big of a deal, radiators have valves built in to allow safe outgassing like you’re describing.
