Onyx Olympus 5 Wood Burning Stove
The Onyx Olympus 5 is a wood burning stove with clean, contemporary lines and a refined, understated presence. It is designed for modern interiors, where its simple form sits comfortably in an open-plan space or a minimal fireplace setting.
As a dedicated woodburner, the Olympus 5 is optimised for burning logs, with Cleanburn and Airwash systems for efficient combustion and clear glass. The steel body is paired with a cast iron door that opens a full 180°. It is A+ rated, meets Ecodesign standards and is approved for Smoke Control Areas as standard. Contact us to find out more.
Onyx belongs to the Stovax Heating Group, whose 40-plus years of British design and engineering stand behind every model. Each Onyx stove is developed and tested in the group’s own laboratories.
Olympus stoves can take their combustion air from the room or, with the optional outdoor air kit, directly from outside the home.
Standard (room air) – The stove draws air from the room it heats. Your installer will advise whether a fixed air vent is needed under Building Regulations.
Outdoor Air Kit – Ducts air to the stove from outside, which suits well-insulated, airtight homes and helps avoid drawing warm air out of the room.
