Banging in my steam pipes since boiler replaced

I have a single pipe steam system. Recently (about 4 weeks ago) I had my old one replaced because it had a crack in it. Luckily I had assistance with a grant to replace it.

Since it was replaced the pipes have been banging and clanging like mad. I did not touch any of the radiators, they are set as they were before it was replaced and there was no noise at all. They are all tilted as should be etc to allow the water to flow back down. I tried emptying the boiler all the way (after it cooled off) and then filling it back up with water but the banging persists. I only have a small house (about 1000 sq-feet) and only 5 radiators and as I said nothing was touched in the way of the radiators when the boiler was replaced. I can't call the guys back that replaced it because to help me with this as it was an assistance program and everything was free. Can't afford a plumber too.

This is so loud it wakes us up at night now.

Any clues as to how I can reduce this noise. As i said before it was replaced I had no noise at all. I had replaced all the steam vents on the radiators prior to the replacement so they are good.

How can I have a quieter house please?

The boiler probably needs to be skimmed... I would start there...


Does the site glass surge up and down on a call for heat?

Show us pics if you can...

Water level too high? Any new piping pitched the wrong direction?

My vote goes to poor piping as the cause. Post some clear pictures of the system, including the piping from the boiler. The steam pro's will chime in.
