Gazco Onyx Olympus 5 Wood Burning Stove

The Gazco Onyx Olympus 5 is a beautifully crafted wood-burning stove that brings together contemporary styling and genuinely impressive thermal performance. With a nominal heat output of 4.8 kW and an operating range of 2 kW to 6 kW, it's well suited to heating small and medium-sized rooms with ease and consistency.

Efficiency sits at the heart of this stove's design. Rated at up to 82% efficiency and awarded an A+ energy rating, the Olympus 5 is fully Ecodesign compliant and DEFRA-exempt, meaning it can be used legally in Smoke Control Areas across the UK. Clean-burn technology, supported by tertiary air jets, promotes more complete combustion, reducing particulate emissions and making better use of every log you load.

Everyday usability has been carefully considered throughout. A powerful airwash system keeps the glass door clear so you can enjoy an uninterrupted view of the flames, while a convector heat system circulates warm air around the room for more even heat distribution. The wide-opening 180° steel door makes loading logs and carrying out routine maintenance straightforward, and the heavy-gauge construction ensures long-term reliability.

Installation is flexible and practical. Both top and rear 128 mm (5") flue outlets are available, and the stove is compatible with a slim 12 mm hearth. An optional external air supply connection makes it a strong choice for modern, well-insulated homes where indoor air quality is a priority.

The Onyx Olympus 5 is designed exclusively for well-seasoned wood with a moisture content below 20%. Avoid treated timber, pallets, and household coal to maintain performance and protect the stove. A carbon monoxide alarm in the same room is strongly recommended as standard safety practice.
