Hi all,
I am the unlucky owner of a Super 90 boiler which has given me all manner of headaches. We have recently had the TRV's changed on the radiators and now our boiler seems to be making a loud humming noise when the hot water is on. The flame looks fine and is blue and it sounds fine when the heating is on only but as soon as the hot water goes on it is really noisy. I dont really want to pay a call out charge for a plumber if it is something easy to fix. Is it the fan or the pump and will my boiler blow up if its not fixed asap. I have checked the pressure and its at 1.5. I really dont know what it could be, HELP!
