Is there a EnergyGuide heating furnace efficiency score for the ES40?

  Resistance heating is pretty poor compared to heat pumps.

    That's the joke that I was trying to make.

      I think I remember reading or overhearing that Intel's chips somewhere in the Pentium 4 era were more efficient at converting electricity to heat than a typical hotplate. (Ratio-wise, at least.)
