Noisy radiator

[LUCIALIA]

I've just fitted a new combi central heating system & cannot stop the rad that is permanently on gurgling. I have bled it & even run the system with the drain valve open to try & purge any air,all to no avail?

 

[Plumbstar Tom]

did you flush the system out?

 

[LUCIALIA]

yep, hot flush & cold flush

Is it a new radiator

Is it gurgling or maybe the pump presure against the rad valve when all other rads closed down,is it happening all the time,open both rad valves up fully on that radiator

Or could be a restriction in the rad

If just fitted ,maybe leave a few days and see if it settles down

imho
