Opus Octave 70 B
There are certain situations where a stove on legs just doesn’t look right and so Opus give you the option of being able to site just the firebox. Whether installed on the optional Opus bench, a purpose-built hearth, or a polished concrete shelf, the Octave 70 will bring the room to life with its warmth and flame.
