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.

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.
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.
