Dollars to donuts, you would probably get the most bang for the
buck by increasing your insulation over that crawl space.

One change I've noticed in a friend's house with increased insulation
is that not only is the temperature more stable, but the place is
quieter because the HVAC runs less.

Also whenever you have a fire going, cold air is being sucked
into the house to replace the air going out the chimney,

Been there, done that. We used to live in an old place and it was
almost as if having a fire in the fireplace made the place colder!

We eventually learned that the fireplace, which was very shallow, was
actually designed to burn coal, so the fireplace really didn't (and
wasn't meant to) work well with wood.

Any electric heater is just as efficient as any other, if
that's what you want.

If the OP wants a quick fix, an electric heater with a built-in fan
would be my recommendation.

If the OP wants a real fix that will save energy and (in the long run)
save money, and as a side benefits probably make the home quieter, the
temperature more stable yearround, and save wear on the HVAC, the OP
will need more insulation and anything else that an energy audit of
the OP's home will recommend.
