If all you want is to heat up the room that the fireplace is in, the wood-burning fireplace with gas logs is the way to go as B-line stated - we have done the same in our house.

However, if you are looking for whole-house heating, a wood-burning stove is a great choice. My parents have heated their entire house for years with wood-burning stoves. Load it up, close the door, and you're set.
