The OKO S4 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 S4 stove is glass fronted and you can operate the door by turning the attached handle by 90 degrees. Completing the look is the supplied log storage which is also finished in charcoal grey and the Adam tall angled stove pipe in black which makes it simple and easy to install by enabling you to place the stove freestanding along with the stove pipe on top.
