Heat pumps are quite a bit more efficient than electric heaters.

  ... only if you're willing to cool something else ;)

    Every time we clean something, we simply dirty something else. Ala Einstein, energy is neither created nor destroyed. Chaos is neither created nor destroyed, simply moved. And to move chaos, requires isotropic heat emission, which releases chaos in itself - hence entropy increasing. Thus, moving chaos, increases the total chaos a little bit. Until there's chaos everywhere and nothing can be moved, ie. heat death of the universe. Prepare for the big crunch, the big pancake deep freeze, the cyclic big bang, conformal cyclic rebirth, or whatever your cosmological spirit holds to be an inkling of inclination. :-)
