Open hearth to central heat in Canadian homes
File opened 2026-05-04. Focus: distribution paths—warm air, water, steam—and how basement mechanical rooms replaced hearth-adjacent fuel storage.

Gravity and duct routing
Early warm-air furnaces used brick encasements and tall stacks to induce draft; suburban Toronto bungalows sometimes retained low-profile trunk ducts beneath floor joists that still constrain retrofit duct sizing.
Hydronic circulation
Steam radiators in Montreal row houses and hot-water baseboards in Prairie bungalows reflect different labour markets for pipe fitting and different freeze-risk profiles. Switching fuels often left abandoned piping in place, documented in renovation archaeological surveys.
Electrification and hybrid layouts
Resistance baseboards reduced chimney dependence but copied perimeter layouts from hydronic systems. Hearths remained social focal points even where inserts or sealed stoves provided auxiliary heat; municipal renovation statistics track continued fireplace retention through national housing datasets.
External checks
Readers weighing renovation impacts should read current efficiency framing on NR Canada and building science summaries published by CMHC for housing stock context.
