I have seen this up on the board and you haven't had much help. You need to be a bit clearer on what you want to achieve. Do you want to heat the room as primary heat or do you want the decorative effect as in the photo? Any small wood insert will heat that small of a room. Actually overheat it. An electrical unit may look nice but that is actually too large of a space for a 1500W unit as primary heat depending on the heat loss in the room.

If it's for décor only get the electrical insert of your choosing. For heat, wood insert with glass doors and the mess and labor that goes along with wood burning. It is a young mans sport. Look at what's available to you in your area for both. The wood insert and all that goes with it can be costly, then there are insurance issues to be dealt with for wood burning.

Thank you for the reply! I was thinking a small wood burning fireplace, with seating. Probably far too large for my space (with dining) so I'm now thinking table in other area, with two chairs and ottoman by fireplace.

The space is 12' wide and I would like to include french doors, but they would obviously not be centered on wall. I'm guessing fireplace would need to be 4' to 5' on each side, with the diagonal being to 6' to 7'.

The chimney would also have a wood stove hooking into it, from another room. Thanks again, for the reply :)
