Our split level ranch has a small family room downstairs with a corner fireplace. I want to put in a free-standing wood or pellet stove to supplement the electric baseboard. I'm worried an insert won't be very efficient, and it still uses electricity. My question: what do you think is involved in removing that corner gas fireplace? I want the walls to meet at 90 degrees and put the freestanding stove in that corner. Would there be much heavy material to remove in the chimney, or could I just rip out the bottom part of the flue (use it for the new free-standing stove), cut out some drywall, and patch it back up? Pictures attached. The back left corner of the dining room appears to contain the flue from the fireplace below it.
