two types,an open and a closed system. Or vented and nonvented. The vented needs the flue open the non vented does not. The non vented puts more heat in the room the vented puts heat up the chimney. the non vented is more heat efficient, but the logs have an aroma to them. The non vented also have a oxygen sensor on them so you do not suffocate from oxygen depletion. I have a nonvented system in my kitchen/family room and it does heat the room nicely. The room measures about 20x20. I have 14 ft ceilings in that area so I have to put the fan on reverse to circulate the heat off the ceiling. If you have a mantle, you must use a shield so it will not catch fire with the non vented. That all being said, I got mine at home depot. Always have a carbon monoxide sensor in the same room.
