...you can? Electric heaters exist?

  Always worth mentioning we should be using heat pumps, not straight resistive heating.

    For sure. Heat pumps aren't the best option everywhere (though modern heat pumps probably function acceptably at lower temperatures than most people realize), but if you need to do electric heating, they are the best option most places.

      For "human" temperatures don't they just degrade back to the efficiency of resistive heating? Or are some places actually cold enough to push the factor below 1?

        > Or are some places actually cold enough to push the factor below 1? Probably some far north, but not that many. My Kaiteki 6600 has[1] a SCOP of 5.1 and a factory guaranteed COP at -25C (-13F) of 3.1.
