Yes mowlston, you have a catchy turn of phrase it seems, not fettered by such inhibitions, such as verbosity. judging by the replies so far.
Noise from plumbing can come from having an air-lock somewhere.
In which case all the radiators need bleeding.
It can also come from a faulty pump. Replace.
Check that the maximum temp setting is not too high; you don't want water boiling anywhere.
Heating will expand the pipes and if resting on wooden beams etcetera, can cause a noisy rubbing sound. I cured that in my old house by having insulation on all the pipes throughout.
The pressure valve on the system may need adjusting. Get a plumber in.
Which is probably what you should have done in the first place.
Unless of course you're just winding everyone up! LOL.
See first answer!
