Yup, if you're heating your house incandescents just lessen heating load. However, if you're cooling your house incandescents are a triple whammy as AC isn't nearly as efficient as heating.

Incandescents heat the room at the ceiling, which I would imagine significantly reduces their effective efficiency relative to a well placed electric heater. Also, of course, incandescents have the same poor system efficiency as other electric heaters, compared to burning the fuel for heat in your house.
