You want either a fireplace insert or a free-standing woodstove standing just in front of the fireplace. Inserts can retain a lot of the look of a traditional fireplace with all the efficiency of a modern stove, but require electricity for the fans. A free standing stove will look different, but most will function decently without electricity, plus you could cook on them if you had to.
Feel free to email me. We went through the experience of installing a woodstove last winter, and it is an experience for sure.
Fireplace not efficient
