The OKO S4 Bio Ethanol Stove combines timeless stove styling with innovative clean-burning bio ethanol technology, bringing the warmth and ambience of a real flame to your home without the need for a chimney or flue. Finished in contemporary charcoal grey, this freestanding stove features a stainless steel bio ethanol burner, tempered safety glass door, and advanced airFLO™ convection technology to deliver efficient heat and outstanding flame performance.
