    There is still a few around. You know your getting old when you've seen your share. I'm sure there a few that have never seen some gravity systems like these. I have to bid a replacement for the hot air system. The dual gravity boiler system I bid on during the summer, never heard back. Rental property.

    I remember the old Arco boilers and Holland furnaces. So does my poor spine. I also remember the taste and especially the smell of the soot that came out of the old firebox when we were junking it.

    It has been awhile since I've seen any so nice and clean!

    Maybe that is why you never heard back.

    I had to look real close at those boiler pictures to see if it was one I took. Friend of mine rented a double in St. Paul for a store. Down the cellar were 2 snowmen just like that only had oil burners in them. He moved, the oil bill was steep!

    At least they knew how to make HX in them days.
    I did lots of those, is that asbestos on there?
    Go make a midnight dumpster run.......

    Cant say Ive ever seen one of those, I also haven't seen the north side of the Mason-Dixon line either, that might explain it

    I would say that is definately asbestos painted silver on those Arcos. I am safe from asbestos disease, as all that I ingested years back is now permanantly covered up by the fiberglass.

    I remember like it was yesterday...cut the drawrods, spilt the sections and use an appliance dolly up out of the basement

    So....somebody explain to me how these things work, where does gravity come into play?

    Warmer water (or air) is lighter, it rises in the pipes (or ducts) and it's volume is replaced in the vessel (or HX) by gravity. Note the size of the pipes and ducts returning to the bottom of each unit.

    Basic law of physics...heat rises..hot water rises up the pipes ..gives off its heat, cooled water returns to boiler...heated..up it goes. This description is a "closed system" I have seen a couple of "open systems" The expansion tank in the attic with open drain to the roof. Same principle except you had to add water occasionally... you had to "know your system." I just pulled an "Ideal #7" 5 section replaced it with a Columbia 4125 with bypass piping. It works fine ..nice slow even heat. Nothing high tech just a reasonably priced system that will last a long time.

    Yea asbestos at both loacals. The boilers are coated withit, the old coal stoker has the 3/8 panels nailed to ceiling in the whole furnace room. The landlord is having problems renting the store where it is located because of excessive gas bills. ya think
