banging pipes

I have a very old oil fired boiler that is serviced yearly by my oil company. Lately, however, we are woken in the middle of the night by extremely loud clanging/banging in the pipes. The noise subsides after a huge burst of steam is heard from the regulators. I have also noticed that with 2 of the radiators that there is a bit of rusty water that is coming out of the regulators as well. One problem - when the boiler was serviced before this heating season they filled the boiler with water. When I went to turn it on, I did not realize that there was water and began to fill - really overfill the boiler. I don't know if this is part of the problem. Thoughts?!?!? Thanks!

This is primarily a UK site, so don't know your systems, but it could be you have overpressurised the system and when it heats up the safety valves are operating. Could be blockages/lack of flow that is causing banging.

Only very general advice though.

Call your engineers back in to check.
wow , you use steam :eek: like in the films where there`s steam coming up through the pavements in the dimly lit `hood :?:

When you take any sort of water heating to its basics for any sort of thumping and banging to occur on a system that normally runs ok it must be a faulty boiler stat or a inlet valve passing and allowing flame to stay on when it should be off that is allowing too much heat to get into system..

When the guy mentions steam i don`t think he means it is a steam system but it is getting that hot steam is being produced
