    That boiler is puny.

    I have buildings that have three or four of these used as water heaters. I realize this is being used to heat the building, but lets just say, if you look at it closely, it will have provisions to use it as a domestic water heater.

    The operator rules typically come to a head when there is a danger of issues if the system is not monitored at all times, this would be virtually any high pressure steam boiler or boiler with "manual controls".

    Other than the boiler you pictured being relatively small, it heats water.

    Also, I would be willing to bet that if you look at the piping diagrams in the installation and maintenance manual, you would not see that piping as an example... I see three mistakes and that's just from a quick glance from a picture...

    "Piping Mistakes"??? Now I'm curious. I will attach two other pictures, for you to view. Could you please elaborate on the "mistakes"? Thank you for your interest.Name:  SAM_2686.jpg

    Where is the blow down leg?

    If the boiler were to be isolated from the piping via the isolation valves, would there be a relief valve?

    Where are the dielectrics between the ferrous and non ferrous pipe materials?

    Where is the vibration isolation for the pump?

    Where is the labeling for identification?

    I could go on, but I think you get the point...

    Looks to me like a lowest bidder deal.

    Thanks for your input. Would viewing a few more pictures help, with your anaylsis?

    I did not analyze it.

    Nor do I care to, my point is that this is a pretty rough and somewhat unsafe install.

    I believe the actual side clearance to flammable materials is one inch, however, I also believe they recommend 24" for serviceability...

    All I am saying is that many times, just because it does not require an operator, does not make it safe, just that it is considered "unregulated" for the most part..

    One of our local city inspectors would run out of red ink on that deal.

    Also would hate to be the one to have to work in that fire panel.......

    Would also want to opt out of replacing the circulation pump on the bottom of the boiler. I'm thinking there was little to no forethought in this install.

    The boiler in my dad's apartment building is about the same physical size as that thing....nobodies sat with it since I flipped the switch on (and performed a routine fall maintenance checkup) In October... It's a hot water boiler, BTW.

    Also that install looks like hell. That may be cause there is not many (if any) in Dallas that actually knows hydronics that well! I sure hope that install is not your definition of what a hydronic heating set up is supposed to look like... You really should take a day off and read the wall at Heatinghelp.com....those people are living proof that steam and hot water is alive and well! and that we don't use "electric strip heat" in the north even though you throw that around seemingly not knowing what electric strip heat really is.

    Ha didn't even notice that, not sure how someone got away with that.
    Edit in the last pics it looks like an optical illusion.

    That is a tiny boiler, I have worked on boilers 10 times larger with know one to be found even near them. There is no reason for someone to monitor them, they have safeties o prevent any dangerous situations.

    LOL, is the pump sitting on a cobblestone?

    Listen to GT (amongst others), he knows what he's talking about. To people who work commercial, that's nothing more than a big HW heater that you'd find in a house. No operator needed.

    I have yet to receive a reply on this question; "Why is district steam not utilized in newly constructed buildings for space heating?" The buildings that are connected to a city's steam loop always appear older. And by older, many date back to the 1800s.

    Thanks for the input.

    Can you give a specific building as an example?

    We don't have any such services in my immediate are, there is however such a thing in SoCal.

    If I were the owner of the building I would insist on it.

    .
    Buildings built after 1982, do not utilize any form of hydronic heat, be it on site boilers or district steam. I could show you plenty of older buildings which utilize district steam for space heating.

    I found some information on another thread where another member of this site said the same thing. I will post that here when I get a chance.

    Why don't you instead do research looking for buildings built after 1982 that DO utilize hot water, steam, or district steam?

    Perhaps you should re read this thread! All the answers to your questions are right in front of you.
