When I was growing up there were still many homes that heated with coal in the 1950's. My parents first house and my grandparents house in Brooklyn, and my first house out on the Island, all built in the 1920's and all had coal bin rooms built into the layout of the house foundations. All the bins were rooms under porches near the street end of the house. With a simple hinged window for the coal shute.
Up until I moved upstate in the 90's, it was not uncommon to hear some Long Islanders still refer to garbage cans as, "ash cans".
My house here, built in the 1800's, still has many lumps of stove coal that had bounced up on the foundation above the shute window where the old coal bin used to be.
And, the basement dirt floor still has the brick-lined, slate covered, cold air chaise that lead from the base of the "octopus", coal furnace, to a wooden duct attached to the front basement wall, leading up to a 3 foot square cold air return floor register near the front doors and base of the front stairs. It steered the cold air back under the furnace to be re-heated by natural convection.
