  • Electric Boiler

    I was wondering if anyone has had any experiences, good or bad with Electric Boilers?
    I'm specifically looking at the Burnham Cast Iron model, but am also considering the Seisco SH-11 because its half the price.

    Experiences? Good / Bad? Thoughts?

    Re: Electric Boiler

    This probably won't be of much help to your situation but the only electric boiler I worked on that had a serious problem (as in fire) was a 'small' one we used to keep an 5000 gal. asphalt tank hot. This feed was 200A @ 480V and the boiler ran 100 PSI steam to all the heat tracing which was wrapped around the piping, valves, etc. in the asphalt system. This was to keep the stuff from rocking up (solidifying) in the lines.

    We were going through pre-operational testing following installation and the lugs where the feeder cables were landed were aluminum (this was early 80s) and the conductors were copper. The repeated heating/cooling caused the lugs to loosen, resistance increased and eventually they caught fire. The Fire Dept. got it out in short order and there was some damage to controls and electrical of course. We got it back up and running in about 4 days after some parts were expedited in.
    "When we build let us think we build forever. Let it not be for present delight nor for present use alone. Let it be such work that our descendants will thank us for, and let us think, as we lay stone upon stone, that a time is to come when these stones will be held sacred because our hands have touched them, and that men will say, as they look upon the labor and wrought substance of them, "See! This our fathers did for us."
