So, because reasons, I'm doing research on what heating/cooking energy source Steve and Bucky would have had in their tenement, and I ran across this gem: "standard to install boilers that were big enough for people to open their windows in the dead of winter and still be warm"

imagine that, people in the 20s and 30s worried about germs floating through the air

another gem
"nearly 75% of Manhattan’s existing square footage was built between 1900 and 1930"
Steve would have recognized a lot of these buildings!! https://www.bloomberg.com/news/articles/2020-08-05/the-curious-history-of-steam-heat-and-pandemics

Here we go: "Each kitchen had a fireplace, ... burned either coal or wood; gas, ... was not piped in until some time after...Cooking stoves, which tenants had to purchase on their own, would have burned coal...and may have been the source of heat."

I have actually worked with a coal fire before. Those fuckers stink. There is no way in hell Bucky or Sarah would have let asthmatic Steve near one for cooking. Guarantee Steve can't cook worth a damn, or at least he'd've learned after the ice.
