These are hi rise condo residences that use natural gas boilers to produce hot water for heating in Winter. Probably for domestic hot water year round as well.
As someone who has designed mechanical systems for large buildings, I am here to tell you that retrofitting these building for heat pumps will be quite difficult, and perhaps practically impossible.
This should be fun to watch.
You can’t legislate basic Physics, Thermodynamics, Combustion, Heat Transfer, etc. It’s like legislating Pi = 3. It simply doesn’t work, despite putting it into law.

You’re right about heat pumps.They’re OK for individual homes
in the south,but certainly not capable in the north in the
winter.
—”This should be fun to watch.”
Any owner of a pre-1990 apartment/building would be better off setting the building on fire and becoming homeless.
20k $ per unit? A joke.
Asbestos abatement and patching alone would consume that in a union environment.
Heat pump window units?only $1000/ window unit, NOT INCLUDING the new metered electric service to each unit; price to be determined.$$$
A commercial heat pump, or three or four to replace the existing gas boiler. Most (NOT ALL) only supply 130 F, a bit short of the 180F of the gas boiler. Lots of extra blankets??? The building may not freeze, but you will.
And new building electric service for the new commercial heat pumps$$$
NB; The legendary efficiency of a heat pump disappears as the outside temperature drops below 20F (Check your COP curve) Do not look at your electric bill if you have a weak heart in cold weather.
Burn them down and claim to be white Hispanic.
