The Opus Octave 90i DS Inset Wood Burning Stove is a practical and visually striking solution for heating two rooms at once. This double-sided stove can be installed in a dividing wall or used as a central feature in an open-plan layout, offering a clear view of the fire from both sides. This layout not only maximises heat distribution but also creates a shared focal point between spaces.
Built for performance as well as style, the Octave 90i DS delivers up to 14kW of heat with an impressive 80% efficiency rating and an A energy classification. It comes with twin 50mm four-sided frames for a clean, modern look that complements a variety of interiors.
