Electric blanket comes to mind there!
There is no need to heat the room I sleep in here in Seattle. I've got 3
comforters which keep me toasty all night with the house as low as 45F. The
room is the last one I'd heat, except for certain special occasions. A
space heater takes care of those just fine, and warms up the bed in 2
needed when I climb in.

That's what I do, 2 comforters with an electric blanket sandwiched in
between. I haven't heated the bedroom area at all so far, and turn the
heat way down in the living area at night; I'll see what adjustments
need to be made for the Nebraska winters.

The fan uses some electricity that isn't converted to heat.
But it is a very small amount.
But, when the radio wave is absorbed by an object, it heats it.

Why doesn't the electricity the fan uses convert to heat?

It does. Some of the power to run the motor is converted to heat and as the
air moves the friction of the moving air converted back to heat.
For all the electricity used inside a house, there are only a couple of
things I can think of that is not converted back to heat inside the house.
That is light that goes out the windows and some electromatic waves that
penetrate the walls. This is usually a very low portion of power compaired
to the total usage.
The only other things I know of is things that have the heat vented outside
such as a dryer.
