Gas and Oil Home Heating Furnaces - noisy pipes & radiators

I would like to know the cure for water hammering on the radiator pipes as well as the radiator, I have tried raising the angle of the radiator a few inches away from the steam relieve valve from the radiator and no luck still as noisy as ever,
i have natural gas heat but old iron radiators.
they do the job but just so darn noisy that sleep is a hard job as it is can anyone give me a helpfull hand on this


thanks:( :confused:

Steam is not really my area but here is some reading untill someone else comes along.

What you are hearing, is the condensate slamming back into the steam on a one pipe steam system, I presume. This is a counter flow system. Most units loose their pitch after seattling of the house, or sometimes a broken pipe support that use to keep the pipe pitched properly. Make sure that you are not using thermostatic radiator valves or the condensate will slam it every time. Make sure the inlet valve is wide open. The radiator itself is pitched. Look at the boiler pressure and it shouldn't be getting over 2# of steam when it shuts off. You may have to actually drain the radiator, or get the boiler pressure to zero, and remove the air vent to speed things along, let it drain for about 20 min, screw the air vent back on. The main is 1/4" per 10', the branch is 1/2" per 10 ft. Make sure the main vent is venting. (not the ones on the radiators). Insure all piping is insulated & The air vents are on the lower tap.

Dan Holohan (the foremost authority on steam) has an excellent web site for steam and books that are excellent reading. Many of the explanations of pumping with circulators and other heating stuff is written by him, you can actually recognize his writting style.
