My boyhood home in Connecticut in the 50's had a big green "octopus" in the basement that burned oil. You could always tell when it first fired up in the winter from a whiff of that oil aroma. It was slightly scary, as was the huge (to a boy) black oil tank in the basement. The last winter we were there, money was very tight, and we ran out of heating oil. I remember having to huddle around a single old electric heater in the living room. In the spring we moved to California and all the heating there was natural gas fired, or electric powered heat exchanger.
Since then some of my homes have had fireplaces - the current one has two. But I don't heat with them much, even though both have inserts with fans to help distribute the heat.
The closest I've gotten to coal for heat was some charcoal I bought in the late 90's. It was made in China and looked like it had been pressed into hollow little tubules. It had an oily aroma and I figured at least part of it was made from coal. It burned OK, though I may even still have some, since I moved to real charcoal and various woods like hickory for BBQing.
I'm not surprised to read that coal fired heating appliances leave less ash and are less labor intensive than wood fired stuff, since coal is more dense and perhaps has residue that won't burn.
