Hello, I have a customer with a modern anthracite vertical radiator and a modern TRV and lockshield.
The radiator makes a loud metallic bang from within the radiator, when it heats up and cools down. I have opened the lockshield fully, lowered the boiler pressure from 2.5 bar to just over 1 bar, turned the boiler temperature down and bleed the radiator. But it makes no difference.
I haven’t experienced a noise like this before and was wondering if anyone could shed some light on it, before we consider replacing the radiator. Many thanks
