Our burners run on bio-ethanol, a clean, environmentally friendly alcohol, extracted from plant residues, offering clean burning free of any smoke or soot. These burners do not require a chimney or connection to a special infrastructure at home, thus allowing complete design freedom, with creative placement of the fireplace in every space, based on any architectural vision. The burner contains an amount of ethanol sufficient for 10-12 burning hours, which allows heating spaces of 20-60 square meters. To double the heating in such space further burners can be added.
