Noisy new system

Randy_22

The pictures help a little, however a picture of the piping that comes back to the bottom of the boiler would be good. You may need to light this area up as the black pipes, dark boiler, etc blend together. Also, when this job is finished it may be a good idea to insulate all the piping in the boiler area to get the heat out to the home. I believe bare pipe has 5x the loss that insulated pipe has.

Noisy new system

I had a new boiler installed in Jan. for a closed 2 pipe steam system. This new system is noisier than the original. I hear water sloshing in the walls, like water being pushed up the pipes, and banging in the basement, which I never heard before. The contactor says they would need to open the walls to see the pipes. This just doesn't make sense to me in that these noises only started when they installed the new boiler - nobody touched the pipes in the walls. I would appreciate any feedback.

Thanks,

noise

is this a steam system or a water circ system?
If it is a water systen and not steam, Noise could be air in pipes. Did you have the noise with the old system?

NJ Lady

steam system and I did not have these noises before.
Thanks,

2 pipe system

By any chance was this the replacement of the original boiler that was in the house .If so the new unit is way smaller yes .Do you know if the contractor replecated the old boilers water line ? If not you may have lost the water seal between the wet returns and drip returns also make sure the pressureetroll is turned down to 1/2psi cut in 1 lb cut out or possible a vapor stat is even better .Did the installer leave the installation instruction with you by the boiler if so open them up and look for the manafactures draing of how the boiler should be piped .If you can post a pic ture of your boiler and it's piping peace and good luck clammy where in NJ

Oh Boy !

First , make sure that contractor does NOT open your walls . More than likely the problem is one , or all , of 3 things ( which keeps your walls intact ) -

The boiler is oversized , the piping around the boiler is undersized and connected wrong , or the boiler needs a thorough skimming and cleaning .

From what the contractor said about opening the walls , I bet it's all 3 . Can you give us a little more info about the system ? What make and model number boiler ? What type of radiation do you have ? How many rads ? And any chance of posting a digital picture here of the boiler ?

It sounds that might have a two story house. I wouldn't open any walls since you said that the old boiler did not make these noises before. Since most likely you don't have a infrared temperature sensor to measure the temperature before and after the trap on each one of the radiators, lets start by doing very simple things first. Lets concentrate on the water noises you hear in the walls and not the banging sound in the basement at this time. Try to determine the wall or area that you hear the greater noise of running/slushing water and shut off the supply valve at the radiator on the second floor above that area. If you still hear the sound, open the supply valve on the radiator you closed before and close the supply valve on the next closest radiator to the first one. You most likely will have to repeat this procedure with a few radiators. Let me know the outcome.

Yes, they skimmed 2x after the install. Haven't any pics because I don't have a digital camera but the township fire and plumbing inspectors both came and gave their okays. (This town requires a permit to replace a boiler).

NJ Lady

No, not a replacement of the original, replacement of a Burham from the '70'. This unit is a bit smaller than the old one and the contractor did mention something about the water line but didn't think that to be the problem. I think I will borrow a digital camera this week and post a picture of the boiler and the piping. In the meantime, I'll have a look at the manufactuers drawing and see if they look the same.Thanks,

There are no valves (or vents) on any of the radiators in the house. The radiators are recessed into the walls and have accordian like things in the middle.

Boiler is a Carrier BS2AAN150. There are 12 radiators, all are recessed into the walls, and 1 in the garage, which is turned off or unhooked.
The contractor skimmed 2x after the install and redid the piping a few times, i.e. adding a trap, moving it and then lowering it before removing it completely. (Original design did not have a trap). Plumbing and fire inspectors from the township both okayed the install. I will try and borrow a digital camera a post a picture to show all you guys. Thanks,

NJLady, this is almost certainly a Vapor system

which was the Cadillac of heating in its day and is still one of the best out there.

When you take your pics, include the boiler and associated piping as well as a couple radiators. Also tell us if you could find any manufacturer's names on any of the system's hardware except the boiler. This will help us ID your system.

You mentioned that a trap was added when the new boiler was intalled and that there were no traps at all with the old boiler. What is the trap's make and number? Can you also include pictures of this trap's connections; pipes coming from and leading to. What is the distance from the trap to the water line?

NJ Lady

They removed the trap and went back to the original design. Should have pics to post in a few days. Thanks for taking the time to respond.

When the old boiler was removed , did the plumber installed a Hartford Loop in the system of the proper size. It is my understanding that on a 2 pipe steam system that there are not any traps in the system except at the radiators. The Hartford Loop also acts like a trap if sized correctly. Also what or how much do the inspectors know about steam. Ours look mainly for clearances, beyond that they are clueless. Are the traps in the radiators working properly?

NJ Lady

Finally got pics of the install.

Modified boiler pics...

Not sure if it helps any, but here 'tis... I split them into seperate pictures, zoomed in 200% and turned them into reversed negatives.

Think we need more/clearer shots of whats going on around the left and right lower sides of the boiler. Closer would help.
