We accessed the ceiling pipes from the attic by removing floor boards, insulation and a cardboard backed reflector material, and then popping up about six inches of the plaster to expose the 1/2" galvanized piping. It is shiny and in great shape. I took some water from the system to test, but it looked very clear. More later...
Best,
Leland

You might check with Bill Flint at Historic Deerfield. I recall learning
in 1970 that they had electric radiant in some ceilings there. (perhaps
it was in the apartment above the silversmith's shop, and elsewhere) I
don't know if it is still performing there, or has failed, or what--but
Bill may know.
