Onyx Athos 5 Wood Burning Stove
The Onyx Athos 5 brings the character of a classic stove into the modern home. Its graceful proportions and heritage-inspired details suit period properties and traditional interiors, while the engineering inside is entirely up to date.
The Athos 5 is a dedicated woodburner, built to get the most from seasoned logs. It has a durable steel body and a cast iron door that opens to 180° for easy loading and cleaning. Cleanburn and Airwash technology keep the glass clear and the burn efficient. It is Ecodesign compliant, rated A+ and approved for use in Smoke Control Areas as standard. Contact us to find out more.
Onyx is part of the Stovax Heating Group and draws on more than 40 years of British design and engineering. Every Onyx stove is developed in the group’s own 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.
