Question Summary
Central heating boiler making an awful noise worse when you turn the tap on have turned it off the noise was really frightening It is a sime E comfort HE it is 3 years oldAnswer Summary
Hi I am Rick, UK Plumber, and I specialize on Boiler problems, can you tell me the make and model of the boiler please, Rick OK the noise you are experiencing is most probably caused by lack of flow through the heat exchanger, so the pump is the first item to check, then the diverter valve for jamming, and blockages in the waterways including the aqua guard filter on the flow pipe just after the heat exchanger, what is the system pressure?if it is low then that can cause it as well, Rick
