Onyx Athos 5 Wide Wood Burning / Multi-Fuel Stove

The Onyx Athos 5 Wide gives the classic Athos design a broader firebox and the flexibility of multi-fuel burning. It suits a wider fireplace or a larger room, with the same traditional styling and heritage detailing as the standard Athos. Its fixed multi-fuel grate burns logs or approved smokeless fuels, so you can choose whichever suits your home and supply. A steel body, a cast iron door that swings fully open to 180°, and Cleanburn and Airwash systems combine robust build with clean, efficient burning. It is Ecodesign compliant, A rated and approved for Smoke Control Areas without an extra kit. Contact us to find out more. As part of the Stovax Heating Group, Onyx brings over 40 years of British design and engineering expertise to its stoves and fires, each created in the group’s research and development laboratories. Athos and 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.
