Ooh. I know this one. Parts of NYC still use a steam heating system that was first designed in the late 1800’s:
Thank you. There’s so many people responding with unhelpful answers.

I’ve never been called a boomer before, I’m far from it. Let me exchange a free idea and information; you’re a fucking moron.
Sorry to have hurt your millennial feelings.
No feeling hurt here. Quite the opposite. Again, allow me express my “free exchange of information and ideas” and my somewhat amused feelings; You’re a fucking moron!
Don’t feed the troll, ignore and move on.
And you, sir, are an accomplished wordsmith! I mean, “fucking moron” twice? Brilliant! Thank you for you contributions!
Wtf? Bad form, Peter Pan.
You should tell this guy.
Imagine having two keyboards just to put your hands in each of them and, like play 4 keys from each… without moving your arms at all…
Wow that’s neat
No, that’s heat.
Yeet the heat or beat the meat
Yeet the meat not the heat.
Steam from the steamed hams we’re having
And you call them that even though they are obviously grilled?
excuse me for a minute
It’s not steam. It’s smoke from wood fired pizza ovens for the turtle men that live there. There was a cartoon documentary about them on tv a few years back.
I never thought of them eating artisan pizzas. I always figured they’d get some shitty dominos.
Ew, gross. They live in a sewer, but they’re not animals.
They’re teenagers, taste doesn’t factor in much after cost and availability.
They wouldn’t do dominos they’d probably get a variation of Rays famous near them
90s dominos also isn’t today’s dominos.
90s Dominos was trash. Even Dominos recognized old Dominos was trash.

I swear I thought this answer was about as accurate as the one that said “dragons”.
How steampunk for probably the largest city in the world to use steam in this day and age? I love it…
I’m going to have to interject, NYC is the 11th [or 35th] largest city.
11th, OR 35th? Could you explain?
Or 3rd or 76th.
It depends on how you define the city, here’s my source: https://en.wikipedia.org/wiki/List_of_largest_cities
I don’t know why they include the surrounding areas as part of the city population. The 5 boroughs is roughly 8 million people. If you live in jersey city, you shouldn’t be counted as part of nyc population
I don’t know why they care about population https://en.m.wikipedia.org/wiki/List_of_largest_cities_by_area clearly land is more important because land votes not people.
That list is from 2018
NYC didn’t grow any more populous since.
https://www.nytimes.com/2024/03/14/nyregion/nyc-population-decline.html
Doesn’t mean other cities haven’t grown. Especially Chinese tech haven and trade hub cities are blowing up. If New York didn’t grow, it probably dropped several spots.
Old steam heating system. They vent it when they’re working on a section.
Side-note: surprised by all the fellow New Yorkers i’m seeing in this thread. I thought yous were still at the other place.
Yep. Detroit has this, too.
Yeah it’s common enough I figured most knew, but a few years ago I went ice skating at the bryant park rink with someone who refused to walk anywhere near the steam. They thought it was toxic and didn’t accept my explanation, so we had to walk an extra few blocks to get around the steam work. Shrug
I wonder if they could make it more efficient by running at a lower temperature and installing water source heat pumps in buildings. https://youtu.be/abGiNL9IT54
That’s a good idea! My understanding is that the old steam network is slated for decommission and replacement by this program, basically a large distributed geothermal heat pump network that also harvests from major heat producers like data centers and provides both heating and cooling.
It will end the era of the steamy-street Sin City aesthetic but should be many, many times more efficient than the old steam system. Phase-change thermal transfer in HVAC systems is nearing 400% efficiency, so 4 times more efficient than the theoretical limit of direct heating, because it only uses the energy necessary to move heat from one place to another rather than produce it, and it works for both heating and cooling.
Right now I believe they’re piloting the system in NYCHA buildings (public housing) of neighborhoods outside the old steam network, like Chelsea and Hell’s Kitchen, but supposedly the plan is to expand to the rest of Manhattan.
Edit: corrected coefficient of performance
That’s the steam from the melting pot
That’s just from the ruins of Old New York that New York is built on top of. The mutants down there are a steampunk society.

Thank you, much a-brie-ciated.
I love how plausible this is
There’s a really good explanation here:
Some big cities originally heated their buildings by producing steam in one one centralized building and delivering it to large buildings thru pipes underground. The steam you see is from leaking pipes in this antiquated infrastructure. It’s a very inefficient method if you ask me. Cities should offer these buildings low interest loans so they can update and be independent but they never take my advice
District level heating is actually pretty efficient, some universities do the same thing on purpose to save on bills. Our relatively young city does it with the downtown skyscrapers for the same reason.
The other nice thing is that when you upgrade the heating system to be less carbon intensive, you can instantly have a ton of buildings all jump instantly to fewer emissions too.
Afaik it’s not inefficient if the heating is done via fossil fuels as big furnaces (especially in the past, especially turbo-fan super-fine grind coal ones) are much more efficient than smol ones for individual buildings (even if the buildings are giant).
It’s terribly inefficient. The efficiency is lost when the steam that condenses back into hot water is lost and none of it is returned to the boiler to be reheated. Rather than reheating this returning water which normally is at 120-160 degrees Fahrenheit, fresh water is used which in the winter here is around 56 degrees. Aside from this the cold water taken in contains impurities such as dissolved gasses which cause corrosion and dissolved minerals which can cause scaling that acts as an insulator raising the amount of energy needed to heat the water.
Oh, I didn’t know it was a one-way system in NY.
A weird decision, but I guess it lowered the initial cost a bit?The difficulty was drainage. Isolated steam systems in steam era construction were designed to use gravity for condensate collection. It’s one of the reasons boilers are always in the basement of old buildings.
Steam system engineering was a well-compensated profession. A well-designed system would accurately predict the rate of condensate flow for every part of the building, prior to construction, and reflect these predictions in the slope/grade and diameter of the steam pipes. Inaccurate predictions resulted in problems like pipe knock (aka steam hammer) which you can often hear when you or a nearby neighbor partially close the shut-off valve of a radiator.
Since construction in the city had many elevations and could not be predicted in advance, there was no equivalent solution to facilitate condensate collection. The system had to be one way. And yes, it’s inefficient compared to modern systems, but was innovative in its day.
I can’t speak for NY but that is the situation in Cleveland. I have a customer downtown on city steam. I watch hot water discharge to a drain at the rate of about 3 gallons a minute and there’s 1440 minutes in a day. When it was built I’m sure they reclaimed most of it (80% return is considered good) but over time the pipe corrodes and you have leaks.

Why not just have the city mandate the upgrades and then implement them? It’s probably not that big of a problem for everyone involved.
If it were that simple everyone would have done it by now. This method of heating your building is very expensive. Long story short, I’m in the HVAC business and two of my customers have made themselves independent. One was a private property management company that gutted an empty building and was successful, the other is a federal building that hired a private company to convert over and got screwed.
You know how when rockets take off in Florida there’s lots of smoke?
Yeah there’s a tunnel that goes from Florida to New York that the smoke goes through to help heat up the New York streets. So anytime you see smoke in New York it’s cause a rocket was recently shot up in Florida.
TechnologyInfrastructure is incredible!The New York City steam system includes Con Edison’s Steam Operations, a piped steam system which provides steam to large parts of Manhattan. Other smaller systems provide steam to New York University and Columbia University, and many individual buildings in New York City also have their own steam systems. The steam is used to heat and cool buildings and for cleaning and disinfecting. It is the largest such system in the world and has been in operation since 1882.
Wow this makes me realise why so many movies set in New York I watched in the 80’s and 90’s often had steam coming up from the ground.
Wow, that was quite a read, thanks. Amazing technology
Amazing for the 1800s
Whole parts of Eastern Europe still transport Steam for heating.
What you think of is district heating, it (usually) just uses warm/hot water instead of steam.
You are likely correct.
We have these in Lansing MI too! Part of the Satanic Panic back in the 80s involved kids playing D&D down in parts of the steam tunnels under MSU, which, I’m told, is much harder to do now unfortunately

It’s the only explanation that fits
Hot. Moist. Air.
it’s steam not air
No it is Moist. Air.
You can’t see steam. It’s not visible to the naked eye.
