Boiler problems - banging noise and only lukewarm water with a fully open tap

My boiler has been banging loudly of late, like someone is hitting it with a hammer. Not only that - when I try to run a bath or even wash the dishes in the sink downstairs, the hot water is very lukewarm with a fully open tap - and I can only get the water to heat up if I close the tap off to a very slow trickle. Filling a bath takes absolutely ages, whereas before the hot water would flow properly with a fully open tap. Does anyone have any idea what's the problem? It's a combi boiler by the way. Thanks!!
