Noises AFter installing new boiler

MaryAnn

Ron,
It's a one-pipe system. The Equalizer runs with piping to back of boiler - doesn't connect to Main. The main connects to boiler in front, which you see. Do you need more information? Pictures. Thank you for your help/advice.

Noises after installing new boiler - pictures this time

Hello, this is a follow up with pictures. I had sent a message about noises after installing V84 boiler (burnham).
October 2005. Problems are:
1) bathroom rad doesn't heat at all.
2) there are 2 tubular rads (one spits heavily; the other a little bit)
3) bedroom convector rad - a lot of noise.
4) noise starts a few minutes after cycle - then not too much noise.
5) all other radiators are convectors.
6) the bed/room rad - I checked is heavily corroded; the wall has some moisture damage. (this may h ave been going on a long time; but now there's a lot of noise.
7) I read Dan's book. I could change vents myself - or call Contractor after heating season to help me when he has more time(last time he came he helped somewhat but was very hurried).
8) I insulated pipes myself (2" pipe wrap); can I go near pipes near boiler? Is that safe
9) I notice there are no main vents (when I insulated, I didn't see any in basement. I know this is not good - I want comfort, though, but money is a factor - one thing at a time - the boiler cost a lot.
10) I'm a do it yourselfer.
Pictures attached this time. I appreciate all feedback!
Thank you,

MaryAnn

Hello, this is a follow up with pictures. I had sent a message about noises after installing V84 boiler (burnham).
October 2005. Problems are:
1) bathroom rad doesn't heat at all (right above boiler).
2) there are 2 tubular rads (one spits heavily; the other a little bit)
3) bedroom convector rad - a lot of noise.
4) noise starts a few minutes after cycle - then not too much noise.
5) all other radiators are convectors.
6) the bed/room rad - I checked is heavily corroded; the wall has some moisture damage. (this may h ave been going on a long time; but now there's a lot of noise.
7) I read Dan's book. I could change vents myself - or call Contractor after heating season to help me when he has more time. The bedroom and b/r vents haven't been changed in many many years. It's probably better to stay with same contractor who put in system. I just need to be more specific and talk to him so we can have more comfort. He'll be back for yearly maint. (Fall 2006).
8) I insulated pipes myself (2" pipe wrap); can I go near pipes near boiler? Is that safe
9) I notice there are no main vents (when I insulated, I didn't see any in basement. I know this is not good - I want comfort, though, but money is a factor - one thing at a time - the boiler cost a lot.

Is this a counterflow system ?

I did not see any return pipe or a Hartford Loop , just the equalizer pipe going to the return of the boiler ? Do you have just the one 2 inch main with no return pipe connected to the far end of it ? There is a certain way to pipe these systems so that condensate will not mix with the steam in the main . This was piped like a gravity return system , different than a counterflow .

Can you take a pic

of the end of the main pipe ? And can you tell us if this main pipe is pitched up all the way from the boiler to the end of the main ?

MaryAnn

I will take a look at the system when I get home and give you the best description I can for the pictures I have.
I think that will be helpful to you.

Sincerely appreciate your help,

MaryAnn

The pipes around Boiler

It is a one-pipe system. There is the main running across the basement. Then a 2-inch pipe (lenght around 52") runs to the pipe you see across the front of the Boiler. This pipe joins a pipe coming up from the top of the boiler and the Equalizer on the side. The Euqalizer (I believe)goes to the back, and then meet the 2" pipe at the back of the Boiler (around 43") going down into Boiler. I think a couple of the pictures should show this. Does this help?
I would note that the insulation I have is 1-1/2"--but I don't have around Boiler. Does it seem to be piped correctly? What do you suggest?
THANKS!!!

Ron this souunds like, kind of a counter flow system. M.A. This means that the steam and the condensate are running in opposite directions. Not an expert but shouldn't the pipe be larger in a counter flow? and it will be critical that all pipes are pitched back to the boiler with no sags. Every where it sags will bang. So from the boiler all pipes should slope up hill.

From what we see here...

...Mary Ann...this is a counterflow system with the condensate returning through the main into the header.

It's not piped the way it should be. It might work this way, but the condensate will rain down into the header cooling the rising steam, and may be caught up in the velocity of the steam and have trouble returning to the boiler. Some efficiency will be lost.

Before we condem the piping though, all the vents should be changed and the boiler should be cleaned. It takes the better part of a whole day to clean a new boiler, and if this wasn't done it will give all the troubles you describe.

You can certainly insulate the pipes near the boiler, and change the vents yourself when the steam is off.

Let's see a photo of the far end of the steam main, past the last radiator. There should be some vestage of a main vent somewhere out there.

Noise after new Boiler/Thanks for the feedback/I will get pic

Thank you for feedback. My plan is to wait until the cold weather passes so I don't get stuck in the middle of a job. I'll change the radiator vents. I believe you just use a wrench. There's a local heating supply store that is very helpful. Should I suggest the Contractor clean the system in the Spring? He said he would send a card when he will service (probably Fall). Should I request sooner. I want to be sure it is a thorough job...I realize it is a full day job. When should the system be ready to clean; I could either call him back or go with an expert in steam. I will post a picture you asked for. THANK YOU FOR YOUR HELP AND SUPPORT. Very much appreciated.
