Specifications for 2-pipe system in large house, 1914

16-18 Oriole Road steam heating specifications.pdf

In researching my own building (1925) in Toronto City Archives, I came across information on the beautiful duplex house from 1914 that used to stand beside us. In addition to blueprints that showed the location, type, and EDR of every radiator, there was this textual specification. I thought it would be of interest in this forum.

That is very cool, thanks for sharing!

Anti-malleable sentiment goes way back:

EBEBRATT-Ed

CI was always the first choice for HW or Steam and was never accepted for gas in most locations Now the new steam installs have gone away (mostly) and HW uses copper or pex the demand for CI fittings is pretty low compared to what is used to be.

Never seen CI in HD or Lowes and even the large supply houses like FW Webb their smaller branches usually only have malleable.

Supplyhouse has it, but it's somewhat out-of-the-way!

This was a 2-pipe air-vent system.

Also, ISTR Dominion Radiator Co. was the Canadian arm of American Radiator Co.

Toronto was home of HHW. Montreal is colder and steam was more common. My experience in Toronto is that in sixty year old buildings steam is preferable to HHW. After a hundred years more so.
