noise when running hot water

Hi.

Just moved in to a house , and when i am drawing water from the hot tap, not straight away , but after a few seconds there is a humming noise , not sure where the noise is coming from but seem to be the area of the hot water cylinder, or the loft.

The system is an indirectect gas fired central heating system.

seem as tho the noise only starts when the cylinder is recieving the cold water to replenish the hot taken, as the noise still goes on once the tap has been turned off. , but what do i know.

is it an airlock, if so how do i clear it, since i thought that running the tap would remove air lock?

thanks steve
