These fireplaces create a comfortable feeling in your home or office with their ability to be hung anywhere. Some fireplaces use gel fuel, purchased separately, to keep the fire going for up to three hours with three cans of fuel while putting off 3,000 BTU's. Other fireplaces are electric but both kinds can also be used to hold candles. Gel fuel is canned fuel that gives you a real flame while electric fuel is artificial as the unit gets plugged into the wall. Fireplace screens are available as well, to cover your hearth when not in use.
