A ventless #fireplace is a heater that either has live flames or one that has realistic looking flame images. These heaters do not produce any smoke, they do not produce any ash, they are cool to the touch, they do not produce any soot, and they do not make breathing difficult for people who have chronic breathing conditions like asthma. These units require no chimney or vent pipes to let smoke escape from the room.
