Rhythmic banging in pipes/radiators at random points in the day

Hi, We had a radiator removed in the front room which has been capped off along with some other plumbing work (pipes relocated under floor boards in front room and installation of a towel rail) and are waiting for the new radiator to be reinstalled post decorating. I'm fairly sure the sounds have started since this visit a few months ago so could be linked. At various points in the day our heating system has a rhythmic clunking sound in the pipes/radiators. You hear a dull click/thud in the airing cupboard then a few seconds later a much louder sound in all the radiators/pipes over the building. It last for 5 - 10 mins then stops and seems to occur randomly - for example, it's just done it now and the heating/water isn't on and there have been no taps or toilets being flushed. Any ideas? Would air in the system cause a regular rhythmic sound like this?
