Onyx Olympus 5 Wide Multi-Fuel Stove overview
The Onyx Olympus 5 Wide Multi-Fuel Stove brings together a broad flame view, clean contemporary lines and a refined cast-iron door profile. A durable steel body, cast-iron door and large ceramic glass window create a substantial convector stove designed for long-lasting real-fire warmth.
Its fixed multi-fuel grate is approved for dried wood or suitable smokeless mineral fuels, giving you useful flexibility without losing the character of a real flame. The firebox accepts logs up to 425mm.
Efficient, controllable heat
The Olympus 5 Wide delivers 5kW nominal heat across a 2.5-7kW operating range. The Wide firebox achieves 77.6% net efficiency on wood and up to 79.5% when operated on an approved smokeless mineral fuel. It carries an A energy rating and meets Ecodesign requirements.
Onyx Cleanburn technology introduces combustion air in stages for efficient burning, while the Airwash system directs preheated air across the glass to help keep the flame view clear. The convector design distributes both radiant and convected warmth.
DEFRA exempt and installation-ready
The stove is DEFRA exempt for use in Smoke Control Areas when installed and operated in accordance with the manufacturer’s instructions. It supports a 128mm (5 inch) top or rear flue outlet, is compatible with a 12mm decorative hearth and can use an optional direct outside air kit.
Overall dimensions are 575mm wide x 641mm high x 370mm deep, excluding the top flue collar and front handle overhang where applicable. WooCommerce shipping dimensions are supplied in centimetres in the import file.

Delivery Information
We offer a nominated day delivery service on many of our products. Where this is selected, we will always do our best to meet your chosen date. For example, if you select a Tuesday delivery, we will typically dispatch your order on a next-day service the working day before.
However, once your order has left us and is with the courier, delivery is handled by a third-party network. While we work closely with our carriers, we cannot be held responsible for delays caused once the goods are in transit.
Deliveries are made on a kerbside basis only. This means the driver will unload the goods as close to your property as safely possible, but they are not insured to carry items into your home or unpack them.
Due to the nature of pallet deliveries, access must be suitable for large vehicles and pallet trucks. If you have any access restrictions, please let us know in advance.
Important: We strongly recommend that you do not book installers, fitters, or any other tradespeople until your goods have been delivered, as delays can occasionally occur.
Returns Policy
We accept returns on items that are:
- Undamaged
- Uninstalled
- In their original packaging
Please note that return costs are the responsibility of the customer.
If required, we can arrange a collection on your behalf, however this service is chargeable.
