Midtown NYC on July 18 2007
If you’ve ever wandered the streets of Manhattan, or watched a movie, you’ve likely to have seen tall orange-and-white striped chimneys billowing clouds from steam vents. These aren’t random puffs of city magic, they’re a fascinating part of New York City’s unique infrastructure.
Sometimes they go boom and explode. On July 18 2007 there was a steam vent explosion and a good day to play hooky. That is, not be around E 41St Street and Lexington Avenue.
Watch the video below to find out what happened that fateful day.
Why New York Has Steam Vents

New York’s steam vents are part of an intricate system called the Con Edison steam system, one of the largest in the world. It’s been delivering steam to power heating, hot water, and even air conditioning since 1882. The Empire State Building is heated with steam.
The system uses underground pipes, some dating back to the 19th century, that carry high-pressure steam beneath the city streets. The vents, those bright chimneys you see, safely release excess steam, preventing dangerous pressure build-up.
An NYC Look
These steam vents have become an unofficial symbol of New York City, a photogenic backdrop for everything from fashion shoots, to moody noir films. Tourists and locals alike are drawn to the surreal, foggy plumes that give New York’s streets an almost cinematic vibe.
Where To See Them
The best time to spot the vents is in the colder months, when the difference between the hot steam and chilly air is most dramatic. Popular areas include:
- Midtown Manhattan: Around Grand Central and Bryant Park
- Lower Manhattan: Near Wall Street and the Financial District
- Around Times Square: Where the bright lights meet steamy streets for truly iconic NYC photos
Tips for the Curious Traveler

Stay safe: Don’t stand too close to the vents. It will cook you like a chicken. They’re part of a powerful system under high pressure.
Go wild with your creative side: The sight of steam rising in front of New York’s historic skyscrapers is perfect for dramatic city shots. It looks fabulous on your wall at home.
Forget standing near a steam drain: It may be tempting to stand on or near a steaming drain or grate, thinking you’re Marilyn Monroe. You don’t want that. The smell is 18th century.

Final Thoughts
Next time you just ‘happen’ to be in the Big Apple, take a moment to appreciate those swirling clouds of steam. They’re more than just atmospheric, they’re part of New York’s beating heart.
