The Hearthstone Clydesdale wood burning fireplace insert. This is the one I plan to use with the living room fireplace.  The two flues have an interconnecting hole in them so the fireplace inspector said we cant use them but an insert like this with stove piping will be fine. This non-catalytic wood insert heats up to 2000 square feet and it has a soapstone interior so it holds the heat well.  Looks pretty warm and cozy to me.
