How Coal Furnaces Kept American Homes Warm Before Modern Heating?

What kept a coal-heated American home warm through the night after everyone had gone upstairs? In a Pittsburgh house around 1940, the answer began with a basement furnace—and the work of keeping its fire alive. Follow coal from the delivery chute and storage bin to the firebox, then see how draft, ash, and a carefully tended fire affected the rooms above. Discover why the last trip to the furnace before bed mattered, and how thermostats and mechanical stokers took over some of that work. As oil and gas spread, home heating changed—but access to new fuels and equipment varied across America. This story of coal furnaces reveals the daily labor behind central heating.
