The Onyx Athos 5 Wide Multifuel Stove combines traditional stove styling with dependable modern performance, making it a great choice for homes looking for both character and efficiency. Built with a solid steel body and cast iron door, this stove feels reassuringly robust, while the large wide glass window offers an excellent view of the flames, creating a cosy focal point in any room. An integrated Airwash system helps keep the glass cleaner for longer, so you can enjoy the fire without constant maintenance.

Delivering a nominal heat output of 4.8–5kW, the Athos 5 Wide provides effective warmth without excessive fuel consumption. Its fixed grate allows you to burn wood as your primary fuel, with the flexibility to use occasional smokeless fuel when needed. Fully DEFRA-exempt, this multifuel 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. The simple air controls are easy to use, giving you straightforward control over how the fire burns, even if you’re new to stove ownership.

Thoughtful finishing details give the Athos 5 Wide its refined appearance, including a knurled door handle with champagne-coloured accents that complement its classic 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 and traditional homes.
