central heating problem

Every time i switch the heating on, all of the pipes and radiators rattle (sounds like a helicopter). Tried bleeding the radiators there were no air locks.

Thanks breezer.

I'll guess with no information, a valve is stuck shut and the pump is running, or maybe something else......

Thermostatic Rad Valves that are fitted wrongly or just faulty are sometimes described as sounding as a helecopter, if you have TRVs fitted turn them off and on one by one and see if the noise stops.
