Very few? Maybe for single family homes, but electric heat is very common in apartments - Every apartment I've ever lived in had electric baseboard heaters.

Apparently it's #2 is the US with 37% of homes.

Now that I live in a single family house I use oil to heat the house - but the boiler requires electricity.

37% makes sense. When you live in a moderate climate and minimally need heating, low capex and high opex makes sense.

Too bad so many air conditioners don’t have reversing valves. One day I want to install a window-shaker “the wrong way” and see how well it works as a heater.

As an alternative, one could put water containers in their freezer and throw the ice outside as it freezes as a rudimentary sneakernet liquid<-> solid phase change heat pump.
