New York City usually waits out snowstorms.
A few days pass, temperatures climb, and the piles slowly disappear on their own.
But that strategy isn’t working this time…
After last weekend’s storm dumped heavy snow across the five boroughs — followed immediately by a deep freeze — the city has rolled out one of its strangest winter tools: giant snow-melting “hot tubs.”
And with another round of snow expected this weekend, they’re likely not going anywhere anytime soon.
“These cold snaps are really hard to deal with,” Acting Sanitation Commissioner Javier Lojan said in a press conference earlier this week. “The snow is just not melting.”
Why NYC had to break out the snow hot tubs
Normally, time does the job. Sunlight, salt, and warmer air slowly break snow down, but this stretch of winter hasn’t played along.
Temperatures have dipped into the teens and single digits in the past few days, causing snow to refreeze into thick, compacted ice that plows and shovels struggle to move.
Bus stops stayed buried, crosswalks have narrowed into slippery corridors, and cars remained encased under gray mountains days after the flakes stopped falling.
“If we don’t melt it, it’ll just sit there for a while,” Lojan said. “It’s not going to go away anywhere anytime soon.”
How the snow-melting machines actually work
Despite the nickname, these aren’t bubbling jacuzzis.
The official name is the Trecan Combustion Snow Melter, and the water inside is heated to about 38 degrees Fahrenheit — just warm enough to melt snow efficiently while controlling how much water flows into the sewer system.
Here’s how it works:
- Dump trucks haul massive piles of snow from city streets
- Front loaders scoop the snow and drop it into the machine
- Steam erupts as the snow disappears almost instantly
- Melted snow drains directly into nearby sewer access points
Each machine can melt between 60 and 120 tons of snow per hour, according to DSNY. In some cases, half a ton of snow disappears in seconds.
Where the snow hot tubs are operating right now
The city owns more than two dozen snow melters, but running them is labor-intensive. For now, eight machines are in operation, spread across the five boroughs.
As of now, snow melters have been active in all five boroughs this week.
Sanitation crews are working around the clock in 12-hour shifts to keep the machines fed, while hundreds of additional workers focus on clearing sidewalks, bus stops, and intersections.
“We want to make sure businesses and residents feel the difference,” Lojan said. “If you go across the city, you’ll notice it.”
Why they’re especially important with another storm coming
Officials say the snow melters haven’t been deployed since 2021, but this winter left little choice.
Forecasts show more snow on the way this weekend — with no meaningful warm-up behind it.
The goal now is to reduce what’s already on the ground so the city doesn’t fall even further behind once the next storm hits.
“We plan on running this system for the next couple of weeks,” Lojan said. “There’s a lot of snow out there.”
Watching a loader dump filthy street snow into a glowing orange “hot tub” that shoots out clouds of steam feels extremely on brand for NYC — strange, industrial, and oddly mesmerizing.
It’s not glamorous, but it’s effective. And as long as the cold hangs on and storms keep lining up, these snow-melting machines are officially part of the city’s winter survival plan.
So stay safe out there again this weekend NYC, and keep your eyes peeled for the hot tubs rolling through your neighborhood.
