I've just had a new boiler put in - an Ideal combi. It makes a peculiar high pitched noise above the (what i imagine to be) combustion noises, that appear to be related to the pump operating. It's quite piercing - I can here it now, two storeys up, clearly. I might not mind, but I chose this boiler partly on the back of a 'quiet' claim made in the brochure.
I've done a recording here:

sort of gives an idea. I guessed at first that it was something making the case ring, but it doesn't seem to be that - makes the same noise with the cover on or off.Thing is, I don't know what 'normal' is here. The plumber thought it was all OK, but I could ask him to come back and take a second look/listen. Any ideas appreciated.
