Installer refuse to work on steam boiler with hot water zones


We have a 20++ years old steam boiler (hydrotherm) on which there is a hot water loop with 2 zones. We need to replace the boiler because the boiling chamber is now leaking more and more. When we called our local gaz company (PSE&G) they refused to work on it saying that the water loop would violate their warranty (not allowed). The water loop was installed following this diagram (http://www.bellgossett.com/Press/waterzone.html) It does have the bypass with the valves and everything, it works very nicely (heating a family room and the whole 2nd floor). I actually found this diagram while reading this forum a year or two back now (don't remember) and this is the second winter it's there.

I'm just wondering if this water loop is going to be a problem with most installers or PSE&G has weird rules? Any thoughts? anybody had the same situation?

Thanks for the help.

    The first mistake that you made was asking PSE&G to replace your boiler. They are notorious for using sub-par contractors for their installations. They may seem to have nice cheap prices but you get what you pay for with them. Any qualified, legitimate hydronic heating contractor should be able to do the job properly for you. Where are you located? If you are in NJ let us know and perhaps we could steer you in the right direction.

    hydrotherm leaking

    I can relate to your problem. I have a PSE&G installed Hydrotherm that's leaking badly above the waterline and it needsto be replaced soon. The "installer" 17 years ago piped the whole thing in copper and it's the sorriest arrangement I've seen. The banging in the morning drives me crazy. I'm in Rutherford, so maybe we can find a good contractor together.

    The banging ................

    Has nothing to do with the system being piped in copper, it has to do with staem meeting water, if it were a large building copper and iron may make a difference due to their expansion rates at different temps, that does'nt seem to be the case. Check the pitch on all pipes from rads to boiler and maks sure they are proper

    What I meant to say was that both the piping layout and materials were incorrectly done. The 3" tapping is reduced to 2" at a bullheaded tee, so I geta lot water in the mains. They also lowered the height of the a main which causes condensate to puddle at one elbow.
