Wood stoves are more efficient than fireplaces since wood stoves contain the fire in a firebox and release the heat through radiation.
A fireplace just loses most of it's heat up the chimney and is more for looks than for heating a home with.
If you're gonna heat your home with wood and have a fireplace you can install a fireplace insert which is a wood stove you install inside of your fireplace which will heat your home much better and they have a blower on fireplace insert as well to help warm your house faster.
