    What sort of noises? Screeches, bangs, buzzing?

    Is it OK if you run the central heating?

    What's the system pressure (on the pressure gauge)?

    Does it make the smae noises at all flow rates?

    What make & model is the boiler?

    What happens if you put the system pressure back up to 1 bar?

    Does it have a water temperature control? How's the problem if you turn
    this down?

    It sounds as if possibly the water is boiling in the primary heat
    exchander. Does this model heat the DHW directly in the primary heat
    exchanger, or indirectly via a plate heat exchanger? Are you in a hard
    water area? Is the scale inhibitor correctly topped up with snake oil? :)

    Fitted properly in a clean system, they are no problem.

    Sound lime the plate heat exchanger is blocked. Best replace.

    Maybe some sediment got moved along the pipework somewhere.
