The OKO S2 bio ethanol stove in charcoal grey offers the brilliance of a real, open flame and lets you benefit from the airFLO convection system for up to 8 hours thanks to the 1.5 litre stainless steel bio ethanol burner. The stove can provide a heat output of up to 3kW depending on the size of the opening which can be safely adjusted by using the supplied control tool. The modern looking S2 stove is glass fronted and you can operate the door by turning the attached handle by 90 degrees. As the stove doesn't require a direct flue in the form of a chimney this can be placed freestanding which makes it simple and easy to install.
