In contrast to a traditional wood-burning stove, a flueless fireplace does not burn wood, but rather pure denatured bioethanol, i.e. pure alcohol. No smoke, soot or ash is produced by bioethanol during the combustion process, unlike wood. Put simply, when burned bioethanol produces carbon dioxide (CO2) and water vapour (H2O) in similar amounts to those present in air exhaled by an adult. For that reason, no chimney, flue or additional ventilation is necessary.
