Yes. My 1947 vintage 2nd house in Pocatello has a coal chute. No longer in use as the city added natural gas lines. Radiators pulled (still have 2" holes in the hardwood floor where the radiator pipes passed through). The boiler is gone. A 95% efficient natural gas/forced air furnace does the job now.
Utah may well have active coal heating via radiators. I've seen long lines of coal cars coming from WY into the SLC area.
I saw a prepper type on a video that bought a couple of dump truck loads of coal at 35 dollars a ton. Had it dumped into a big hole in his backyard and covered it in dirt.
Ten tons of coal in his own personal backyard coal mine in case of end of the world.
Amazing.
