Not to pick nits (or 'knits'), but electricity used does not *create*
heat. Electricity used *is converted to* heat. And the amount of
heat that results is EXACTLY 3.413 Btu per watt 'consumed'. The fun
part is that it is irrelevant of what else is being done by this
electricity - lighting the room, spinning a turntable, chilling your
beer, projecting an HDTV image on a big screen, etc. The amount of
heat that results is EXACTLY 3.413 Btu per watt 'consumed'. In a very
real sense, all of these are simply free byproducts of the electricity-
to-heat conversion. And (getting sorta back on topic), during the
heating season, the efficiency of these devices is irrelevant - there
is zero energy wasted (discounting, of course, leaky windows,
inadequate insulation, etc). Each and every Btu dissipated by these
devices reduces the demand on your primary heating plant by exactly
But wait -- it gets even better! (this blew my mind when I first
heard it expressed this way) Assuming an 80% efficient gas furnace,
each Btu dissipated by your electric appliances/toys reduces the
demand on your primary heating plant by 1.25 Btu (an 80% furnace
sends .25 Btu of this up the chimney). You actually consume *less*
total energy, albeit at a higher cost, when you leave the lights and
the TV on all night! (Tell THAT to your 'green' friends who just
spent a small fortune replacing all their incandescent lamps with
CFL!) Pretty wild, no?
Of course, during the cooling season, it's a very different picture.

That changes when you know that electricity is such quantities has to

as much electricity as it would take to heat it in the winter.
Exactly and although heat may be the lowest form of energy and all
energy may end up converted to heat in the end, the heat may not be
where you want it.
So back to the heaters, the one that wastes the least energy is the
most efficient, by heat output. The light and sound may end up being
heat but it may also be outside your property.
That's true. Buy, typically, when talking about space heaters, "where
you want it" is usually in the room where you place the heater.
That's certainly the case in the context of this discussion.
Any and all energy 'consumed' by an electric space heater is
dissipated as heat in the room in which it is placed. They are 100%
efficient, by definition. That's why efficiency ratings are not
required on electric space heaters (didn't you ever wonder about
that?). One heater that is deemed 'better' than another is better
only in terms of bells, whistles, and/or durability (although
consumers frequently pay a hefty premium for slick marketing).

all this talk about vibrations I'm picking up. lets write a song about it.
Oh yeah, the Beach Boys already did it:
I'm picking up good vibrations. She's giving me excitations.
I'm picking up good vibrations. Ooo, bop-bop, good vibrations.
She's giving me the excitations. Bop-bop, excitations.
Good, good, good, good vibrations.
I've seen a good vibrator get some girls really hot when I had to take a
break. Some girls are worse than guys. :-))))))))
