Noise from slender radiators

Steamhead (in transit)

If the boiler is piped like your diagram shows, Gerry is right- it's wrong. There is no header to help separate water from steam, so the water goes out into the system and bangs. Post a pic to be sure.

Also, if there is any oil sitting on top of the boiler water, it will interfere with steam production. There should be a skim tapping somewhere on the boiler, which I'll bet the installer put a plug in that will be very hard to remove. Once it comes out, a pipe nipple goes in and you skim according to Burnham's instructions to get rid of the oil.

Noise from slender radiators

I recently bought a house built in 1924 which had the original Arco 'snowman' boiler in the basement, a coal burner which at some point was converted to burn oil. I had the old boiler replaced with a gas-fired Burnham
boiler and have had problems with hissing vents and
water hammer ever since. As part of the boiler
conversion my plumber installed new Ventrite #1
adjustable radiator vents on all the radiators. He
has been back several times to adjust the Pressuretrol
and vents but cannot seem to solve these problems.
The water hammer occurs mainly at 2 radiators
on the first floor which seem to be hot water radiators
judging from the low height & skinny columns, and the plumber suspects this might be part of the problem. The hissing occurs at all seven radiators.
I have insulated the mains in the basement, checked
the Pressuretrol, which is set at approximately
1.25psi Main, 1psi Differential (subtractive), and
turned the radiator vents on the noisy radiators down
to #2 on the dial to try to slow the rate of
condensation in the radiators. All of this has
lessened the noise slightly but has not nearly solved
the problem. I am wondering A) if there are different
vents that I can install to lessen the
hissing/whistling noises, and if there is anything
I can do at the first floor radiators short of trying
to find steam radiators to replace them. I have no
idea what to do about the noisy 2nd floor radiator. I
would appreciate any advice you might have.

okay,

first- if thats how he piped the boiler its wrong..post actual picture to be sure..second, is the boiler water clean? has it been scimmed several times? third- the firing rate may be to high..your old boiler made steam ''slow and steady''..your new boiler will make steam like right now..in huge quantity..have your installer fire that boiler in a manner that will mimic the coal boiler..if not, it will drive you nuts figuring it out..also gorton brand vents would best serve your system.
