No pics handy, but have a large open wood burning fireplace, and the most helpful purchase I have made to date to make my wood burning more "efficient" was to buy the grate wall of fire fireplace grate. In short, the grate allows the hottest part of the fire (all of the embers at the bottom) to stand vertically and blast heat out and not up. I say "economical" because any open fireplace is probably less efficient than just keeping the flue shut and the central heat on. But for one heck of a warm fire, take a look at this grate - I can honestly say this significantly increases the amount of heat radiated into the room versus my old traditional grate setup. It also looks nicer. I am a weekend warrior, but still burn through 3/4 of a cord a winter and absolutely love this addition.
