I have a Baxi back boiler that works fine when Central Heating is selected but is very noisy when the Hot Water is selected. I get creaking and banging of the pipes from the boiler.
If I select the Hot Water and Central Heating at the same time I Do Not get any noise!! It only happens when the water is selected on its own. Can anyone help please. Could it be that the Hot Water circuit needs a flush?
