A little bit of a mystery here: A Church that doesn't heat very well, and certainly not very efficiently.
The building consists of a small partial basement housing the boiler, a ground-level entry foyer and meeting hall, and the 2nd floor sanctuary where service is held. There is inaccessible crawl space under most of the building.
There were (are) 4 plenums (for lack of a better term, -what do
we call these enclosures?) housing 4 banks of 20 each H.B. Smith Gold Pin radiators. Two plenums are in the boiler room, and the other two are at the opposite end of the building higher up on the first floor. These heat the 2nd floor sanctuary through 5 (one plenum has two grates for some reason...) floor grates.
The entry foyer is heated by standing Crane radiators, and the meeting hall is heated alone by the steam pipes running along the walls. The pantry, library, and nursery are heated by Serpentine (my term) "radiators":
