I've had the boiler (Optia) serviced not 3 weeks ago and tonight when I turned it on, the noise coming from it resembled that of a vacuum (normally its just a dull, deep rumble). It begins when the boiler starts but doesn't get quieter as it goes, it stays loud enough to be heard throughout the house. The boiler itself is a condensing model and only 2-3yrs old. Does anyone have idea what may be causing this loud noise? The boiler itself lights up ok and is producing hot water/radiators, it just sounds so very loud all of a sudden and not particularly healthy.
Any suggestions would be much appreciated.
Thanks
