Honestly I’ve lived in NYC my whole life and didn’t realize how big steam was. Of course I’ve seen the smokestacks all over but I never really questioned the origins of the steam or what it’s purpose was other than to be vented into the street lol
ive lived here, not as long as you, but i always just accepted steam everywhere lol without understanding it, but being curious of course as to where it came from and why
Yeah, after a while you stop questioning where it's been used for. Figured it would had to do with their subway system and didnt give it much thought after. Whenever I seee a movie taking place in NY, you just see the steam, unlike any other city I know, coming from every other block. Is it actual warm in the winter when you'd stand on it?
@@nlx78 my mom that grew up in the city just told me "its the vents for the subway" and that was the end of it. i just assumed that all the brakes on the trains made that much heat that it turned into steam and kept the subways warm
True innovating idea to use steam for all those buildings as it can be very versatile. Saves space from needing appliances to create their own heating and any leaks will just leave water.
Sure, back at the time when the alternative was coal. But today? This system is EXTREMEMLY inefficient by todays standards. From an energy perspective it's a literal nightmare. Thousand hundred of miles of pipe, all super hot, just leak heat, and actual leaks of steam is energy pouring down a drain. When he said he expected his company to keep going for another 100 years I cringed.
The cool thing is that you can actually use this for air conditioning as well. Steamjet air conditioning was fairly common in large buildings in New York, high pressure steam was used to draw a vacuum and this vacuum lowered the pressure inside an aeration chamber that would quickly lower the boiling point a bit and this evaporation happened much quicker which would cool the water and the chilled water was pumped throughout the building through the radiators.
Although I'm a born and (partly) bred New Yorker, I think what's just as impressive is how industrial London was powered hydrolically (cranes, lifts (elevators) etc) it was all powered by water pressure and gravity.
I used to work on pressure reduction stations in the buildings, and the heat exchangers. The noises they make are frightening if you don’t know what’s normal and what isn’t. Some of the heat exchangers look like huge submarines.
New York City native here I use a steam stacks in order to tell the weather for today. If there's high pressure in the area then the steam will funnel up wards. If there is low pressure then the steam will lazily exit the stock and disperse closer to the ground
@@tjlovesrachel Which are both influenced by pressure. But I know u can't really seperate them. If we're more so focused on the form the fluids are taking though the main variable is pressure
Adsorbtion cooling made it all feasible. The winter demand for heating made the whole system near idle during summer. So however inefficient, the airco demand filled up that hole for the show completely.
My cousin and I walked through 59th Street along 5th Avenue, and she avoided the steam and was upset that I lured her to it. She thought that it was dirty smoke. And I had to explain to her that it’s just steam - nothing to worry about as it is water vapor. It smells bad? It just smells like boiling water. That’s it. Completely harmless. We’re literally breathing in a lot of particulate matter coming out of exhaust pipes from cars and it builds up inside our lungs, now that’s harmful. Remember, steam is just water. Just think of it as a free humidifier for the streets. It brings down dust and moisturizes the dry air.

Long after it closed I worked in Battersea power station London. When it was built to pacify the locals they agreed to send steam after it generated the electricity, under the Thames into buildings for heat and hot water. The company failed to see the power plant would close and need up having to install steam generationers to fulfil the contracts. It was really interesting t walk into a ruin as vast as that is and find one area still working
Great video but please lower the music volume in the audio mix. The music is often overpowering and makes it really difficult to hear dialogue properly.
This is quite interesting-I have seen steam-powered shovels and pile drivers on construction sites in Manhattan as late as the early 1980s. I've seen a steam-powered dredge in the Hudson in the early 1990s. I used to be a boiler inspector in New York State and the vast majority of boilers used for building heat are steam boilers. A hot water boiler is fairly rare. I now live in Toronto, Canada and here the vast majority of heating boilers are hot water systems. Here, steam is mainly used in industry and rarely for building heating. There are central heating plants here that send steam to downtown office buildings and condos but in those buildings the steam goes through heat exchangers where it heats hot water which is what is used for heating. There is also deep-lake cooling where cold water from Lake Ontario, where it is taken in from one mile out and is 34 degrees year round is used for building cooling. The discharge is then sent to the potable water plants. Ajax, Ontario has a central steam heating system as that's where all the munition plants were during WW2 and having boilers in these plants would be quite dangerous. This system is still in use but on a much reduced basis from the 1940s.
looking for your thoughts on this. I did a massive project job at a the Cliff Central cooling plant in Ottawa like 11 years ago. Re tubing chillers and stuff. One of the of the plant engineers there told me that they use High Temp High Pressure water. I asked why not steam, he said its because it needs to be really high pressure and high temperature to keep it from condensing in the pipes. Where as the high temp high pres water has such a high thermal mass as water, plus you don't need steam traps in the buildings which makes for a more reliable system. Just wondering if that was true and if you have an opinion on it.
plants producing Stem are West 59th street, east 74th Street,east 59th street under 59th street bridge, east river station 14th st,Hudson ave station Brooklyn,Ravenswood station in Queensalso the Woolworth bldg in lower manhattan!!!I worked in all of them! as a Welder and Mechanic!
Here is an insane idea, build a nuclear power plant underground and pipe the steam that comes out (at least a good chunk of it). You get clean energy and the by-product is steam
I think for now we should focus on decommissioning coal plants, we can think about gas later. Even for a gas plant, this is doubly efficient, using its heat loss productively so it would be even further down in the list of carbon intensive infrastructure.
I thought the same thing! I consider myself a pretty knowledgeable person, when I clicked on this video I was like "well duh, of course they're powered by steam that's where most electricity comes from". Then I realized that's not what they meant. Then I thought oh ok, this is an April fool's joke. Nope! I had NO IDEA steam in NYC is piped to buildings like any other utility. Crazy!
They use a steam jet to pull a vacuum on a closed water loop. This causes some of the water to evaporate and chill the water. The steam and evaporated water is then sent to a condenser to expel the heat. And the chilled water is sent to areas that need cooling.
@@beback_ not really, it's an application of Bernoulli's principle and evaporative cooling. There's no engine involved except maybe to circulate the water. The most complicated device is the steam ejector used to pull the vacuum and that's really just a couple of pipes, 2 cones, and a steam jet.
Your giving false information about the purpose of the orange striped stacks.

Con-ed acts like this is such an amazing system that's reliable and safe. The reality is, is extremely dangerous and the system is more than a century old in desperate need of an upgrade. The entire infrastructure in Manhattan is old and run down and con Ed refuses to spend the money to fix it. They even tried to sell Manhattan to national Grid for $1. Yes that's right ONE DOLLAR. And national Grid refused. That's how bad the entire infrastructure is. Not just steam, the gas and electric. There's always an explosion or failure somewhere. How con Ed is still licensed to operate is beyond me.
I worked in an industrial plant that used steam from a near by power generating facility. We had to have mixing valves installed to cool the condensate to below 140 degrees per discharge regulation.
I think the percentage of new york city that is getting that steam is well under 5% of the city and probably less then 1% of people live in buildings heated by central steam ( New York City is much more than just the island of Manhattan which has less then 25% of the population after all ) . Its a hard thing to say the city is powered by it given how few people and buildings are actually heated by central steam
Not that many buildings are served by steam, but the largest buildings all are. So it’s hard to know exact numbers, but just going by connected buildings is a bit misleading
Very interesting. What I find very interesting is the fact that the steam is clean. If it wasn't, then the steam pipes and end-applications would corrode from the inside. And that would get very, very expensive to maintain. So what do they do with the steam after the energy is released and it returns to water form? That would be very pure water. Do they just flush it down the storm drains? Do they send it back to the steam plant? It seems such as waste to have distilled water only to throw it away. It would seem to me that it would be far more efficient to have a closed loop system with a pure coolant, like how a nuclear reactor works. They would have to introduce new pure water to compensate for leakage loss and steam cleaning applications.
I was wondering the same thing. Once the steam is condensed into a liquid it still contains a lot of heat (making it easier to boil than tap water). Is it pumped back to the plant to be converted to steam again or does that hot water just go down the drain?
the steam goes through a steam trap which basically just separates steam from water. The water would then be pumped back to the main plant, reheated back to steam and used again. Water makeup is always needed as you are going to have leaks in the system. but the water is just in a loop. Open ended systems probably still exist, but i would bet their are rare and in the process of being phased out.
It seems wasteful, but I imagine that a pumped condensate return system for a system the size of NYC would be way more complicated than just pushing steam through pipes. Especially since condensate is corrosive, so you need to add chemicals to the steam which means you can't use it for things like humidification. That plus all the pumps you would need would be a ton of effort to maintain.
In coordination with the city Could certain areas attach devices to the steam lines with mini turbine type generators and run some additional electrical power for small areas or some modified version of this?
@@Gonzo13eth Wait, so they run the steam right into radiators and boilers? Isn't it a bit dangerous to have steam right inside your home? I figured they only lead steam into a local substation, heat up water there and then distribute it through the building. My boiler once exploded due to a faulty regulator, and not only did it ruin all of the bathroom cabinets with a limited amount of steam but I couldn't go inside to cut the valve for at least 30 seconds.
@@velikiradojica yep, the Steam condenses into hot water in the actual radiators. Old apartment buildings in New York are famous for radiator knocking instead of just hearing a quietwhoosh as the water gets pumped. It is indeed to avoid using pumps, because of how old the system is. Because the radiators are designed for steam, even if a building disconnects from the conEd steam to use a boiler in the basement, it still provides similar steam instead of just hot water.
When I visited NYC for the first time last summer, I was really confused as about these Pipes and the steam that was coming out of it. You can even see my reaction in my first NYC video. After thinking about i guessed correctly that it was about heating, but only this video gave me the answer as to why they release steam on the street
How much asbestos gets into the pipes from the asbestos insulation, and how much asbestos is distributed from the vents and steam pipe bursts that are so common in NY?
I'm not too certain but I think it's just the asbestos dust that's harmful to our lungs, and the dust won't be carried out with the steam. As far as I know asbestos is only harmful if it's exposed and deteriorating or if it's being handled.
@@Progan666 The pipes burst with enormous pressure, I can't imagine how NY isn't littered with asbestos. There was one article about this happening but I fear it's highly underreported, instead it's shown as a cute quirk of a cosmopolitan city.
The mixing of music vs. voiceover is really weird, especially around 06:03 to 06:26. Why turn up the music so loud at 06:16? I had to listen to it a couple of times, and when I still couldn't hear what the Con Edison-guy is saying, I was saved by the auto-generated captions. Also, I find it so strange that New York is touting how clean and efficient it is to use steam for everything, but it's generated through burning gas... And the steam stacks that release all of that steam throughout the city seems so incredibly wasteful to me. The city in Europe that I live in uses hot water for heating and hot water, but it's not generated with any fossil fuels, and we don't dump it on the sidewalks (but we do have some heated sidewalks during the wintertime).
As a boiler operator steam is not going away anytime time soon and is going to be here for a long...long time. It's the heat source that needs to change and the answer is nuclear ☢️
I'm surprised to see that only half of the steam plants generate electricity before the steam goes to customers. Might as well take advantage of the high pressure steam
nOwHeRe oN eArTh... bro, like all Eastern Europe has been this exact same thing for like 70+ years, not just big cities but even some villages and small towns... 😅
huh, I thought those things were for redirecting hot air away from the street level so it doesn't block ppl and cars' views. I didn't know it was steam, I thought it was just really hot air that just looked like that because of the cold air (I've only seen them in the winter).
7:43 those things with the LCD screens are steam meters. I believe there's a turbine mounted inline with the service pipe that measures volume (like a large gas meter) and that's integrated over time on the computers in Mlbs (1000lb of steam). I've also seen older, smaller buildings where it's just a mechanical meter mounted right onto the pipe, but it does basically the same thing.
@@slowanddeliberate6893 Possible, but doubtful it's used again for efficiency reasons. Steam jet cool was something from the 1930s: en.wikipedia.org/wiki/Steam_jet_cooling
Those tubes are only used in the winter when it's cold to keep the steam clouds above the traffic. In the warmer months it's not a problem and the tubes are removed.
"Why New York Is Powered By Steam" Welp, time to put on my top hat with brass goggles OVER the brim. It'll go nicely with my pocket watch that has extra gears on the OUTSIDE for some reason.
How does cheddar always find the absolute worst humans to interview? The fact anyone over the age of 5 would thank that steam was a result of underground water vapor or a natural gas pipe just spewing toxic gasses out in the middle of the nations largest city makes me sad.
3.2 million pounds of steam per hour, what kind of measurement is that, you can have 1 meter squares of steam which isn’t a lot in such a small place that the pressure is 3.2 million pounds
I don't really get how steam is used for heating, in most places I've been in Canada the furnace either works using electricity or natural gas to heat air that then goes through the ducts.
The steam is piped throughout the building to radiators and baseboards. Through conduction, the metal and pipes heat up. The heat is then transferred into the spaces by convection. As the steam transfer heat to the metal surroundings, it condenses and change to a liquid (steam condensate). This phase change releases a comparatively huge amount of energy. Then cold air comes into contact with the hot metal and then rises as hot air displacing the air above. This creates very slow air currents that allow the space to heat up. Its because of this that it’s much slower to heat up buildings compared to your forced air (fans move the air) system. It’s an efficient way to heat up a lot buildings, but no one is really building new steam systems anymore unless it’s for a specialized system. They’re outdated and more complicated then newer hot water or ducted systems.

I think the percentage of new york city that is getting that steam is well under 5% of the city and probably less then 1% of people live in buildings heated by central steam ( New York City is much more than just the island of Manhattan which has less then 25% of the population after all ) . Its a hard thing to say the city is powered by it given how few people and buildings are actually heated by central steam
Underrated comment
Not that many buildings are served by steam, but the largest buildings all are. So it’s hard to know exact numbers, but just going by connected buildings is a bit misleading
You are probably right … and it’s only Manhattan that’s it
Would it be more accurate to say that Manhattan is thermally powered by steam?
@@dadanifit no , most of it is powered by hydro , nuclear and coal . a small area has some buildings getting steam for HVAC
Very interesting. What I find very interesting is the fact that the steam is clean. If it wasn't, then the steam pipes and end-applications would corrode from the inside. And that would get very, very expensive to maintain.
So what do they do with the steam after the energy is released and it returns to water form? That would be very pure water. Do they just flush it down the storm drains? Do they send it back to the steam plant? It seems such as waste to have distilled water only to throw it away.
It would seem to me that it would be far more efficient to have a closed loop system with a pure coolant, like how a nuclear reactor works. They would have to introduce new pure water to compensate for leakage loss and steam cleaning applications.
I was wondering the same thing. Once the steam is condensed into a liquid it still contains a lot of heat (making it easier to boil than tap water). Is it pumped back to the plant to be converted to steam again or does that hot water just go down the drain?
the steam goes through a steam trap which basically just separates steam from water. The water would then be pumped back to the main plant, reheated back to steam and used again. Water makeup is always needed as you are going to have leaks in the system. but the water is just in a loop. Open ended systems probably still exist, but i would bet their are rare and in the process of being phased out.
it gets dumped down the drain.. NYC does not have a condensate return system.... they should but they dont.
It seems wasteful, but I imagine that a pumped condensate return system for a system the size of NYC would be way more complicated than just pushing steam through pipes. Especially since condensate is corrosive, so you need to add chemicals to the steam which means you can't use it for things like humidification. That plus all the pumps you would need would be a ton of effort to maintain.
@@kelvarnsen this, is probably the main reason.
Is this the "How It's Made" voice??
Haha it is not! Very similar though.
In coordination with the city Could certain areas attach devices to the steam lines with mini turbine type generators and run some additional electrical power for small areas or some modified version of this?
If it would work like that it woul have been done like that. So no
Copper cables are much cheaper.
Why steam and not hot water? Do you superheat it? I've never heard of steam being used for district heating before.
My guess is water would need a lot of pumps to move up buildings.
@@Gonzo13eth Wait, so they run the steam right into radiators and boilers? Isn't it a bit dangerous to have steam right inside your home? I figured they only lead steam into a local substation, heat up water there and then distribute it through the building.
My boiler once exploded due to a faulty regulator, and not only did it ruin all of the bathroom cabinets with a limited amount of steam but I couldn't go inside to cut the valve for at least 30 seconds.
It's like you guys didn't even watch the video.
@@velikiradojica yep, the Steam condenses into hot water in the actual radiators. Old apartment buildings in New York are famous for radiator knocking instead of just hearing a quietwhoosh as the water gets pumped. It is indeed to avoid using pumps, because of how old the system is. Because the radiators are designed for steam, even if a building disconnects from the conEd steam to use a boiler in the basement, it still provides similar steam instead of just hot water.
@@DJRenee tell me Suzie where did they answer my questions in the video?
"Why is there smoke coming out of your city, New York?"
"That isn't smoke. That's steam, steam from the steam power we're having. Mmmm steam power!"
When I visited NYC for the first time last summer, I was really confused as about these Pipes and the steam that was coming out of it. You can even see my reaction in my first NYC video.
After thinking about i guessed correctly that it was about heating, but only this video gave me the answer as to why they release steam on the street
they don't intentionally release it, those are leaks or on cold days the evaporation of the hot pipes / rain water hitting the pipes and evaporating.
Why do I feel like I already watched this video? Even though it just came out, dejavu
maybe this? th-cam.com/video/QRKzA8JlYBU/w-d-xo.html
Familiar format
How much asbestos gets into the pipes from the asbestos insulation, and how much asbestos is distributed from the vents and steam pipe bursts that are so common in NY?
I'm not too certain but I think it's just the asbestos dust that's harmful to our lungs, and the dust won't be carried out with the steam. As far as I know asbestos is only harmful if it's exposed and deteriorating or if it's being handled.
@@Progan666 The pipes burst with enormous pressure, I can't imagine how NY isn't littered with asbestos. There was one article about this happening but I fear it's highly underreported, instead it's shown as a cute quirk of a cosmopolitan city.
@@RoboticusMusic nyc is littered with asbestos. We're still chewing on asbestos from the World Trade Center.
Detroit also has a steam system serving the downtown area. 2nd City Detroit had a review called “Detroit…Steam Cleaning While You Walk” in 1994.
I always wondered where do the doors on the ground and also the building basements go. When I was a kid I was excited about secret passage ways.
The mixing of music vs. voiceover is really weird, especially around 06:03 to 06:26. Why turn up the music so loud at 06:16? I had to listen to it a couple of times, and when I still couldn't hear what the Con Edison-guy is saying, I was saved by the auto-generated captions.
Also, I find it so strange that New York is touting how clean and efficient it is to use steam for everything, but it's generated through burning gas... And the steam stacks that release all of that steam throughout the city seems so incredibly wasteful to me. The city in Europe that I live in uses hot water for heating and hot water, but it's not generated with any fossil fuels, and we don't dump it on the sidewalks (but we do have some heated sidewalks during the wintertime).
It would be cool if they could utilise the 'residual' or 'surplus' steam to heat up a large tropical glasshouse
What's the cost per month to heat and cool vs Electric ?
As a boiler operator steam is not going away anytime time soon and is going to be here for a long...long time. It's the heat source that needs to change and the answer is nuclear ☢️
Can't get enough of narrator's voice
So can you turn salt water into fresh water with some adjustments?
Ima let anyone outside of nyc watching this. Nyc housing heat works off this steam and in the winter it's amazing but dangerous for dry skin lol
I'm surprised to see that only half of the steam plants generate electricity before the steam goes to customers. Might as well take advantage of the high pressure steam
Sometimes that steam leaks into other conduits underground and cooks the wires inside. Copper and fiber optic lines dont play nice with steam
Does the water get re-used or is it all boiled off and released?
This question was answered in the video.
Guys, the music is too loud in some parts.
nOwHeRe oN eArTh... bro, like all Eastern Europe has been this exact same thing for like 70+ years, not just big cities but even some villages and small towns... 😅
soundtrack at @4:04?
Found it. Le Chat Noir
huh, I thought those things were for redirecting hot air away from the street level so it doesn't block ppl and cars' views. I didn't know it was steam, I thought it was just really hot air that just looked like that because of the cold air (I've only seen them in the winter).
How does Con Edison know what to charge ? Unlike electricity where a meter is used what do you use to measure how much steam is used ?
7:43 those things with the LCD screens are steam meters. I believe there's a turbine mounted inline with the service pipe that measures volume (like a large gas meter) and that's integrated over time on the computers in Mlbs (1000lb of steam). I've also seen older, smaller buildings where it's just a mechanical meter mounted right onto the pipe, but it does basically the same thing.
Is it adequately protected from toxic chemicals or other materials being introduced? ב''ה
Hmm informative video but I can't help but feel like this video sounds like one of those they show you when you join the company.
how does the steam-based air conditioning work on a thermo-mechanical level?
My guess is they use the steam to turn the compressor of the AC loop. VERY inefficient and wasteful.
My guess is they mechanically condense the steam into a cold liquid.
@@slowanddeliberate6893 Possible, but doubtful it's used again for efficiency reasons. Steam jet cool was something from the 1930s: en.wikipedia.org/wiki/Steam_jet_cooling
Steam is the best heat!
they should retrofit nuclear reactors into the cogenerating plants, free steam from the cooling system
you have to also set up a storage facility for spent fuel and that's a major hurdle.
1:56 that laugh 😂
That music was so bangin
Those tubes are only used in the winter when it's cold to keep the steam clouds above the traffic. In the warmer months it's not a problem and the tubes are removed.
Or they are working on this site?
Just a note to production: audio is terrible, the music drowns out the dialog.
Thanks Gabe
Didn’t you upload this already?
"Why New York Is Powered By Steam"
Welp, time to put on my top hat with brass goggles OVER the brim. It'll go nicely with my pocket watch that has extra gears on the OUTSIDE for some reason.
Steam Punk, ain't ya?
Are these the same buildings our Dept of Energy wants to heat with heat pumps?
New York City really seems like one of the coolest and most unique cities in the world, I hope to visit it one day.
Those are a lot of leaks they got there.
Super interesting glad I clicked
Do Manhattaners have a steam bill then?
Wasn't there a game or a movie where the city had steam pipes everywhere?
I used to wonder about steam in some movies about Newyork
How does cheddar always find the absolute worst humans to interview? The fact anyone over the age of 5 would thank that steam was a result of underground water vapor or a natural gas pipe just spewing toxic gasses out in the middle of the nations largest city makes me sad.
Next do Chicago's Chilled water line
Wow! Blown away by this. Had no idea about this. Thank you. Great video.
Why the awful background music
I remember the stacks never was there it was just coming from the ground 😏👌🏽
The source of steam is water, is it suistainable in terms of source if it is normal drinking water?
The water has to be purified water. This was explained in the video.
@@DJRenee thanks for the reply. I meant the sustainability of water as a source for steam. Large volumes of water overall going to waste
@@kq7739 most of it condenses back into the system, only a little bit leaks or is vented due to pressure.
I was hoping there would be more discussion about the efficiency of cogeneration
pounds and gallons... nice video but I didn't understand anything 😂
Why not electric heaters
3.2 million pounds of steam per hour, what kind of measurement is that, you can have 1 meter squares of steam which isn’t a lot in such a small place that the pressure is 3.2 million pounds
Get with the joneses. What a waste of water.
Just as interesting as when you released this same video last year
I love to photograph those steam pipes and the steam itself creates a very atmospheric vibes on nyc
I wonder if they can apply this in the coldest city on the planet?!. YAKUTIA in Russia
I don't really get how steam is used for heating, in most places I've been in Canada the furnace either works using electricity or natural gas to heat air that then goes through the ducts.
The steam is piped throughout the building to radiators and baseboards. Through conduction, the metal and pipes heat up. The heat is then transferred into the spaces by convection. As the steam transfer heat to the metal surroundings, it condenses and change to a liquid (steam condensate). This phase change releases a comparatively huge amount of energy.
Then cold air comes into contact with the hot metal and then rises as hot air displacing the air above. This creates very slow air currents that allow the space to heat up. Its because of this that it’s much slower to heat up buildings compared to your forced air (fans move the air) system. It’s an efficient way to heat up a lot buildings, but no one is really building new steam systems anymore unless it’s for a specialized system. They’re outdated and more complicated then newer hot water or ducted systems.
The temp of this SuperheatedSteam is 0ver 700 degrees!
Wow I never thought I'd be in a steamy internet video
Geothermal FTW
"When you maintain... you have to maintain it"? Oh, boy, was that some "DEEP" commentary!
Can/do some buildings take supplied steam and generate electricity on-site?
A lot of cities in Europe use steam power, especially in old soviet countries.
