Gazco Onyx Olympus 5 Wide Multifuel Stove

The Gazco Onyx Olympus 5 Wide is a contemporary multifuel stove that brings together refined styling and serious heating performance. With a nominal output of 5 kW and a usable range of 2.5 kW to 7 kW, it is well suited to small and medium-sized rooms, while an efficiency rating of up to 79.5% ensures that very little fuel goes to waste. Ecodesign 2022 compliant and DEFRA Smoke Control exempt, it is equally at home in urban and rural settings alike.

Burning is made straightforward by the stove's fixed grate, which removes the need to swap components when switching between well-seasoned hardwood logs and approved smokeless fuels. A clean-burn system with tertiary air jets works alongside an airwash function to maintain efficient combustion and keep the large viewing glass clear, so you can enjoy an uninterrupted view of the flames throughout.

Heat is distributed effectively thanks to a built-in convector system that circulates warmth around the stove body and into the room quickly and evenly. Installation is flexible, with a 128 mm flue outlet configurable from the top or rear, compatibility with an external air supply, and a compact footprint that works with a 12 mm hearth.

The stove is built around a robust steel body and features a 180-degree opening cast-iron door for easy loading and maintenance. Finishing details such as the anodised door handle with its black knurled grip and champagne-coloured ends give the Olympus 5 Wide a distinctly premium feel that suits modern interiors.

Every Onyx Olympus 5 Wide purchased through an authorised retailer and registered accordingly is backed by a reassuring 10-year warranty, reflecting the confidence Gazco places in the long-term reliability of this stove.
