    Boiler expansion tank replace

    The boiler system at my police dept. has a leak in the side of the expansion tank due to rubbing on a support cros beam. We are looking to replace it with a bladder tank (or 2) that would rest on the ground ,because the original tank is ceiling mounted and would be a Bi%$# to remove with everything in the way.. the onlty numbers I have are from a Manchester tank tag on the tank. This building has no startup reports ,O/M manuals ect..

    the tank that has a leak
    Manchester tank
    cat#302543
    120 gal
    MAWP 125 psi @ 650f
    SH .114
    HD .094
    -20f@125psi

    We have 2 Lochinvar copperfin 2 boilers,1512000 btu output. and 32 reheat coils throuout the building

    Near Aurora IL..


    if anyone could use these numbers to come up with a replacement ,that would be great

    Thanks

    there are variables to sizing these things. you should go to "watts" site or "b&g", they may have sizing formulas available.

    I have tried that road , but I couldn't even begin to guess how much water is in the system. I was hoping for a cross reference of some sort..

    Why not put it out to bid and let the lucky co figure that out and take the risk.

    I have to believe that a test can be performed to determine the amount of water in the system.

    I would contact a water treatment company and ask for their assistance in this.
