The OKO S4 Bio Ethanol Stove with Log Store combines the timeless appeal of a traditional wood-burning stove with the convenience of clean-burning bio ethanol technology. Finished in stylish charcoal grey, this freestanding stove features an integrated log store base that enhances its authentic appearance while creating a striking focal point for both modern and traditional interiors. With no chimney, flue, or gas connection required, it offers an easy way to enjoy the warmth and ambience of a real flame almost anywhere in the home.

At the heart of the stove is a premium stainless steel bio ethanol burner with a 1.5-litre fuel capacity, delivering up to 3kW of heat and a burn time of between 3 and 8 hours, depending on the flame setting. The tempered safety glass front provides a clear view of the dancing flames, while OKO’s innovative airFLO™ convection technology helps distribute warmth more effectively throughout the room. The adjustable burner can be safely controlled using the supplied flame control tool, allowing you to tailor both the flame height and heat output.

The integrated log store completes the classic stove aesthetic, making the S4 an ideal choice for homeowners who love the look of a traditional log burner but want the simplicity of a vent-free installation. Suitable for living rooms, garden rooms, home offices, and extensions, the OKO S4 delivers genuine flame ambience with minimal maintenance and no ash, smoke, or soot.
