We have radiators throughout our house and have banging in the pipes when the heat is on. Is this a sign of something or is it rather normal for this type of heating system? We just replaced our boiler so I don't think that is the cause. Any ideas? |

There are lots of threads on this topic if you search the forum but the bottom line is: banging comes from steam meeting standing water and that only happens in horizontal piping and radiators.
Don't be so quick to excuse your new boiler, though. A bad installation can cause water hammer for various reasons.
Can you post a picture of it?

On a new boiler install the first place to look is the 'near boiler' piping, with a good look at the mains.
After that you have several things to look at next, but that new main piping is the first.
Do post a picture. It helps a lot. |

Walk around the house with a level and see if the radiators are balanced. Carry some pennies with you. Radiators should be ever so slightly tilted such that the water flows back through the system, avoiding the thunder that comes when water remains in the unit and meets steam the next time around.

Also check the air valves on each radiator. They are the silver or painted bulbous looking things on the side opposite the floor valves. They get over looked and if painted they get "gooked up". They sell ones with a small dial on the bottom so you can adjust as needed. they are about 15-20 a piece but a one time purchase. Simply and gently remove the old one and screw the new one back in. over a couple of days play with the setting. I suggest you start right in the middle setting. First though is to make sure the radiators are angled toward the floor valve.
You may want to disconnect the radiator and drain all the water out. Turn of valve first and let cool. If the floor valves are very old and rusty - DON'T DO THIS.
Also you may want to wait until after the winter is over before removing the radiator just in case the floor valve needs replacement. you'll have all spring and summer to "tortue" yourself with this job
