I'm Stumpped !

in THE MAIN WALL
My helper, a well qualified plumbing apprentice who's about to hit journeyman, asked me a stumper.

We were disassembling a steam boiler today, and came across this Hoffman Pressure Differential Loop. While I understand the way it works and what it's purpose is...I was all agog when asked how it was put together ! How Was IT ?

All the threads appear to be right handed...but I'm really curious and puzzled. Oh Guru's of the Old...please help. Thanks. Chris

    i would suspect that

    its not all right handed threads...better question is why remove it? don't you feel it belongs in the house?

    Knowing Chris and Scott , I bet it's a whole house conversion to a more suitable heating system . Now before anyone goes batty for what I said , I do believe steam heat is right up there with radiant for comfort , our customers tell us all the time . But the challenge is what to do with all the low flying piping that is associated with steam . Is it a whole house renovation Chris ?

    You got it Ron.

    The rest of the home is now eletric and it has grown by a factor of 3. The original part that was steam heated was just 7 rooms and the boiler was GROSSLY oversized.

    I'd still like to know how these were constructed. Even if there are left handed threads on top or bottom, how did they do it and have them not leak? JCA

    It has to be right-and-left threads

    The Dead Men used these all the time. You had to get them caught just right, but if you did they worked fine. I still see them out there occasionally.

    The rest of the house is electric? That must be extremely expensive to run.....

    The secret will now be revealed Chris, they used the "original" version of the Pro-Press. See, there is nothing really new in this industry.

    It IS extremly expensive to run and thats part of why we are there.

    They main part is that, as Chris said, its a mish/mash. New W.M. forced hot water boiler to do the indirect and another W.M. to do seven steam rads. and the boiler is three times to large with Copper Piping. Its pretty ugly.

    We (Chris and Helper ) will replace the steam boiler with a Buderus and then tie that in with the exsting W.M. to handle the load.

    You'll see some great photos from this one.

    No Way **** !

    This is when Men were iron. I took out almost 300' of steel pipe today, and that proves it !

    We will be keeping the radiators in the old part of the house as 7 of 8 have been pressure tested and hold at 40 psi with a few minor repairs. The 8th one, we had a bad time with as an elbow fell apart up over the sill, right behind one of the many electrical sub panels....we'll get to it Monday.

    This is going to be an interesting project, to say the least, but the "conserver in me" wants to keep the old section as intended with the beautiful hunks O' cast iron that have lived there for so long. Chris
