The Onyx Athos 5 Wood Burning Stove blends classic stove styling with modern, efficient performance, making it a perfect choice for homes that want traditional character without sacrificing reliability. Built with a robust steel body and cast iron door, the Athos 5 feels solid and dependable, while the large glass viewing window provides a clear, inviting view of the flames.

Designed to deliver excellent heat with minimal waste, the Athos 5 offers a nominal heat output of 4.8–5kW and achieves efficiency of up to 82%, helping keep running costs low. The advanced Airwash system helps keep the glass cleaner for longer, while Cleanburn technology improves combustion and reduces emissions. Fully DEFRA-exempt, this wood burning stove is approved for use in Smoke Control Areas, making it suitable for homes across the UK.

Heat is distributed evenly thanks to the built-in convector system, which circulates warm air gently around the room for consistent comfort. Everyday operation is simple and intuitive with a single air control lever, giving you full control over how the fire burns without unnecessary complexity.

Thoughtful finishing touches give the Athos 5 its premium feel, including a knurled door handle with subtle champagne detailing that complements its traditional proportions. Installation is flexible, with compatibility for a 12mm non-constructional hearth and the option to connect an external air supply, making it suitable for both modern airtight homes and more traditional properties.
