I also mentioned that about anything new built in Indy is on district steam & chilled water. I gave the example of the new city hospital. 3 boilers are being added to a new central plant and the building will be tied to the existing steam & chilled water lines. Also 4 of the 5 Marriott hotels just built including the worlds largest JW Marriott are on the steam & chiller loop. Lucas Oil Stadium which hosted the Super Bowl 2012 is across from the steam plant and served by district energy. The convention center, new IU Health buildings, a large new "City Way" shop & hotel complex just opened... All told, over 200 buildings downtown are heated and 50 cooled by district energy. Many buildings with dying chillers tie into the loop instead of replacing chillers. On Monument Circle, the Circle Tower and the Monument both did that, the World War Memorial, Embassy Suites...
Yes, I can see office buildings without access to this service doing without a boiler. Many will use large packaged units on the roof instead of boiler/chiller. But as I also posted, most schools built recently do have boiler/chillers. A new Renaissance Inn in our suburb has an air cooled chiller and a couple boiler stacks. Also in our suburb, a new 2 building performing arts center is served by a small district energy plant. City hall and the cop shop tied into it. On a bitter morning, you'll see steam from a cooling tower on plus steam from the boiler stacks.
Boilers over 50# here in Illinois have to have 24/7 monitoring. other wise it is up to the facillities manager. Insurance provider. Small boilers big bombs!
This reminds of a story that's not really on topic at all but I feel like telling it anyway, there is this banquet center that has about 30-40 residential split condensers out back, and I assume an equal amount of gas furnaces inside somewhere. I thought somebody had gone mad and paired clusters together for each banquet room. Last year I had gone there for an event, and to make matters worse, come to find out that each split condenser/furnace operated as a SEPARATE system.
Each single banquet room had 5-10 zones each. There were remote sensors placed every 10 feet on the walls....couldn't imagine what the room with all the thermostats looked like! :Faint:
To this day I wonder WTF they thought they were doing. :confused:

Originally, central power plants were the way to go. Two, 3 or 4 pipe systems were the way. Now it's more or less small water source heat pumps located in the inaccessable ceilings.
Two reasons for this. Most local codes require a permanent on site building engineer where there are large chillers or boilers. This is expensive. Second, chiller/boiler rooms take up entire floors of space that could be use for rental income. So ceiling mounted heat pumps take up no rental space, just a cooling tower on the roof. And no building engineer needs to be on site.
So the answer is it depends on when the building was built. Early 80's and before you probably will have central chiller/boilers rooms. After that it's all individual systems located in ceilings.

You're right, everyone else here is wrong. This thread can now be closed and destroyed.

Ask away, all the questions you want. I for one will never ATTEMPT (since you can't comprehend what you read) to answer one again. :censored:
Here is a valid question that I have;
In going through the TDLR Boiler Records, I have seen many licensed Boilers that are for the purpose of providing domestic hot water. Many laundry centers, hotels, apartments have a "boiler" listed for the purposes of: "hot water supply".
My question today is; Why are these units called "boilers" when they are doing the same thing a water heater does??? A commercial water heater does not have to be licensed, regulated etc as a boiler does. Why not have a large water heater??
Any information is appreciated. Thank you.
PS: The “boilers” listed for providing hot water supply could not too large, as I have seen these units listed as being located in smaller places such as apartments and even restaurants.
