noisy pipes

Marc_20

I know this is probably an age old question here but I looked back and could not find an answer. So I have an older home with the old fashon radiators. This summer we had a whole house wood stove put in and ended up draining the whole system twice. Before we installed the wood stove the pipes would "bang" maybe once when the heat came on, now they "bang" about 30 times over a minute when the heat comes on. I have bled off all the radiators and they all heat up normally. I'm wondering if we should drain the system again and try to fill it up slower or if there is anything we can do about it.

Where do you hear most of the banging? If it is coming from the boiler itself it could be lime build up on the bottom of the boiler causing a rumbling sound shortly after the burner comes on. You can treat it with a good boiler inhibitor cleaner.
