I turned on my (combi boiler powered) heating for the first time this
season a few days ago, and the pump made one hell of a racket. I was all
for calling out a plumber when I realised I hadn't bled the radiators yet.
A quick bleed of the top radiator (I have one higher than all the others,
so all the air ends up in that one) and the pump is near-silent again.
Interesting, what kind of racket?
I only ask coz I wouldn't describe the noise we get as a racket, just quite
loud.
I could hear it in every room in the house. It sounded like a sort of
metallic scraping noise, hard to describe, but a bit like dragging a bag
full of metal things over rough concrete. I thought a bearing had got
mashed or something.
