Do you have a microbore pipe system. (Tiny 6 or 8mm pipe) or the new standard of 22mm/15mm ??

From your discription I would suggest that you have a flow/blance issue with the system as a whole. Try to rebalance the system to see if you get an improvement.

If you have a microbore system the pipes/boiler may be blocked and require flushing and treating with chemicals.

needless to say there are numrous other more serious issues that could cause the noise so i would recommend you call out a boiler ngineer check it out.
