in THE MAIN WALL
You may remember these pics of a steamer from a week or so ago. It was about 17 years old before it rotted out this fall. Most would agree that there's some pretty poor piping to boot. Total EDR was about 235 with a few missing rads. One 2 inch main about 30 feet and another about 10 feet with no insulation. Boiler was 175,000 input.

    And new life

    Here's the new install. A 112,500 input Dunkirk, New 2 1/2 inch drop header, new return header below the water line, Full size 2 1/2 inch return piping to blow down valve and inspection/ cleaning port, 2 1/2 inch cross with inspection/ cleaning/ skim port, 3/4 inch customer skim valve with hose coupler off the bottom of the cross. And a Hartford loop with shut off and drain valve for the return. 2 new Gorton vents... one still to be installed. Insulated the piping too....much cooler in the basement now. Oh and by the way, the vent pipe now slopes up to the chimney.

    Looks great!

    Let me guess, you're waiting for a Gorton #2 for the long main?

    Thanks, Steamhead and....

    Actually,I just wanted the system to get a little cleaner before I installed it. Not having trouble getting them around here. A supplier just down the road was bought out by a big outfit from Chicago and has them on hand.

    Always the kidder....

    Glad to hear from you. Using more and more of your Zone Valves. Twas wondering, were you down in Rochelle to look at a Presbyterian church's controls few weeks ago? It had old Barber Coleman controls... most of which appeared to be bypassed and just gone.

    Wasn't me...but,

    Our field office that covers Rochelle is called "Alpha Controls" now and they are located in Rockford, Peoria and Springfield. They may have been out to see the system. If you need there contact info I can get it for you.

    Let me ask....

    I see alot of gas fired steam here...they are dry base boilers, correct? Wouldn't an oil fired, wet base boiler w/ a GOOD quality conversion, (say a riello)(NOT one of these gas company midco jobbers) do a better job w/ steam and efficiency? Oil design has a bigger steam chest and heat transfer area, does it not? Just thinking here in NH.kpc

    curious

    The Hartford loop looks low. Where is the water line?

    We typically keep the loop 2" below the water line.

    Never installed a Dunkirk before.

    I suspect you're right....

    But have never worked with oil. The boilers are defintely taller, so I suspect you'd get a nice big steam chest. I don't know of any lower input standard atmospheric gas boilers with big steam chests. If you start to look at larger "commercial" boilers..ie Dunkirk D-247, they get some steam space. I think the Burnham Independence give you more steam space than many residential steamers, but the tappings are only 2 inch and on top, so its very difficult to inspect the boiler topside once its piped in. The 247 starts out at 300mbh in, way too big for most residential systems.

    I see what you mean..

    The water line is at 24 inches, and the Hartford loop is specified to be 6 inches below this. This works out to about 6 inches above the centerline of the bottom tapping, which appears to be where it is.... That return tapping and piping is 2 1/2 inch so it can fool the eye a bit. If you look carefully at the bottom of the guage glass you'll see the minimum water level is an inch or so below the bottom of the guage glass. Thanks for pointing this out, I double check this.
    My previous post with another Dunkirk steamer I had the Hartford loop higher than specified...about right at the waterline, however, haven't had any hammer at the loop... just out in the poorly sloped system piping when the water is dirty and the Ph high. Lots of really hard water round here.
