I have an old boiler - must have been fitted when the house was built in the 1980's. Don't know what it is but in order to get hot water I have to have the heating on if there is none in the tank. Anyway, down to the heating, after I have switched I on for about an hour the pipes bang in the walls. If I have run a bath then I can have the heating on for longer before the banging starts, so I am assuming the banging starts when the water tank has reached a max temperature?? If I keep the heating on through the banging it eventually quietens to more of a whirring sound. Can anyone help? It's costing me a fortune turning it on and off and is freezing in the morning! I have tried bleeding the radiators, no air is coming out.
