"we replaced our compact flourescent lights with incandescent lights. When heating with electricity, there is no advantage to using flourescent bulbs"

I'm not understanding this statement ?

When heating the house at a given outside temperature that means you need to "burn" a certain number of electrical watts, so replacing the incandescents with those other bulbs doesn't really save you anything except that the heat from the bulbs is in the wrong place for creature comfort, at the ceiling. Heating the ceiling could also increase the heat loss through it. But at 100 watts per bulb?

I see his point as far as that goes. Incandescent bulbs in lamp fixtures (which are usually lower than eye level) make sense. Any RE person's criticism of incandescents usually goes like this: Incandescent bulbs are space heaters that jut HAPPEN to also put out light.

So if you're using them as a 100W space heater, and you're getting light, that's great! Switch to the CFLs in the summertime. Well, or install a skylight. :-)

Yes, It's almost time to switch back to CFL's. We don't need or want the extra heat in the summer.

Incandescents also throw out infrared - more so than visible light. So even near the ceiling much of the heat is thrown toward the floor. (And reflectors that direct light downward do even better for infrared.)

Also: A ceiling fan can bring the rest of the heat down (along with other heat that ended up there) using far less energy than adding more heat down low.
