Anecdote: All 7 developers in my Houston team (semi-geographically scattered in the city) lost power; half for >24 hrs (it's 10-25 degrees F here for the last 2-3 days).

Gas furnaces need power for the circuitry & blower. My experience with fireplaces is that the house winds up net-colder, but you can warm yourself with radiant heat while it burns. Freestanding wood stoves on the other hand are very capable of warming a large space.
Why is that?
EDIT: Oh are you saying that the rate of heating provided by the fire is less than the overall rate of heat leaving the entire house?
