As Ed and others have pointed out, dp is basically off his rocker here.
You have electric heat, and presumably an electric stove and an
electric water heater. You have electric lights, electric television,
electric radio, electric water heater, electric air fresheners,
basically electric everything. And here is the crux of the matter: any
electricity you use (with one very minor exception, and one slightly
larger exception) is being used to heat your house with near 100%
efficiency (that is, almost all of the energy in the electricity is
converted eventually to heat).
The two exceptions are:
(negligible) If any sound is leaking from your house, then the energy
contained in that sound isn't getting transfered to your house, but
instead is getting transferred to the trees, air, and grass outside
your house. But sound at the levels that are hopefully found in your
house contains almost no energy at all -- otherwise you'd be able to
feel the warmth of your radio's music, after all.
(slightly larger exception) The water that goes out the drain pipes is
sometimes warm, and so carries heat out of your house. So your concern
should not so much be to save hot water because heating water costs
electricity, but simply to avoid situations where hot water is going
directly down into the sewers or septic tank. Even in a very long
shower, if you actually went and felt the water as it leaves the house,
it would be pretty cool. A long shower might use a lot of hot water,
but that heat finds its way into your bathroom, your bathtub, the
supply and drain pipes, your basement or crawlspace, etc., and very
little of it actually leaves your house.
All of dp's suggestions for the kitchen are bogus (in the winter). My
wife cooks a lot of bread in the winter -- it warms up the kitchen,
tastes great, and is a actually, technically, a teeny bit more
efficient than our furnace (there is no chimney/flue loss, at the cost
of having to breath the byproducts of combustion).
So go ahead and make soup, bread, and whatever else you want. Hell, go
ahead and leave the oven door open a crack if you like too. Besides,
with a nice warm kitchen and a bowl of hot soup, you might feel
comfortable setting your heat down a few more degrees in the rest of
the house. Go ahead and leave the TV on if you like (in the winter)
too, and feel free to use all the plug-in air fresheners your heart
desires, and change out those efficient floursecent lights for
ultra-high wattage incandescents if that is what you want to do (in
In summary: the nice part about electric heat is that it is such a
stupid way to heat a house that you can't possibly lose out -- most
anything else you do in your house can't possibly be more expensive
than electric heat.
