Tangential topic : There was a post on HN a while back about steam heating. This talk on YouTube was linked. It was really informative: ▶ this video
As I suspected before clicking, that article cites that explanation as being given by steam heating system expert Dan Holohan. He has a talk up on YouTube that I came across a few years ago. It is interesting on a number of levels, and I recommend giving it a watch: ▶ this video
"When you see something that's old and it's been there for a long time and it's working, don't laugh at it." (From a not-really-related yet quite interesting talk I watched a while back: ▶ this video --- also featured on HN at link )
> I've sometimes wondered if it would be practical to operate a steam heating system at a partial vacuum so that the condensation/vaporization could occur at a lower temperature He actually talks about exactly this in the video! ▶ this video "You'll be sending steam up into the building at temperatures, in some cases, as low as 150 degrees" (83 degrees C)
