Comment on Why is there steam coming out of the streets in New York
TBi@lemmy.world 6 days agoI wonder if they could make it more efficient by running at a lower temperature and installing water source heat pumps in buildings. youtu.be/abGiNL9IT54

That’s a good idea! My understanding is that the old stream 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 currently as much as 400% 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.
