Immerse yourself in the realism of the Gazco Onyx Fusion electric fire! This stylish and innovative inset fire can be installed as a single-sided, two-sided or three-sided configuration allowing it to seamlessly fit into any living room. This widescreen electric fire is sure to catch the eye of anyone who enters the room. It features a realistic Chromalight Immersive flame effect that is created by a combination of LED lighting and a unique holographic projection system. This creates the illusion of a real fire, complete with dancing flames and glowing embers.

The Gazco Onyx Fusion also comes with a range of features that make it both convenient and easy to use. It can be operated using a remote control, allowing you to adjust the temperature and flame settings from the comfort of your sofa. It also comes with a thermostat that ensures that the room remains at a comfortable temperature. Not only that, but you can control the fire and all of the amazing features through your smartphone thanks to the Mus Flame app giving you full control of the fire at your fingertips.

Boasting a 2kW heat output, the Onyx Fusion fire will offer an instant burst of warm heat to take the chill out of the room. The fire can be enjoyed with or without the heat and the Open Window Detection system senses if the room temperature drops by 4°C within 8 minutes, if it does then the heater will automatically turn off to save energy. To further enhance the effect of your Gazco fire, an optional mood lighting kit can be purchased which includes 6 metres of LED strip lights that can be positioned around a TV or along wall-mounted shelves to create the ultimate media wall experience.

Any order under £100 is subject to a £6.95 shipping fee. Deliveries take place Monday to Friday however we can deliver on Saturday and Sunday for an additional cost.
Free Click & Collect:
If your item is in stock, you can order it online to collect from one of our showrooms or warehouses. This could mean you'll get your product even quicker than we can deliver it to you. When ordering your goods please state in your order comments which showroom or warehouse you would like to collect from and on which day. Feel free to contact us for collection information and locations of our warehouses.
Delivery Information:
Your goods will usually be delivered on a 10-tonne vehicle (about the size of a bin wagon). If there is likely to be a problem with access please contact us in advance of placing your order. Examples of areas we cannot deliver to are long or gravelled drives, areas inside walled cities with height restrictions, narrow lanes, grassed lawns, steep drives, narrow gateways or up/down steps. We may be able to make alternative delivery arrangements if you contact us in advance.
With our standard delivery service, there will be one driver, we suggest you have at least one other person with you to assist. The driver will move the goods to the nearest accessible wheel point depending on access. Unfortunately due to insurance and health and safety issues, the driver is not permitted to move the goods inside your property but can wheel them into a garage. 
We advise that you check the goods while the driver is still there. The driver is obliged to wait for up to 10 minutes, (for palletised goods only) whilst you unpack and check the goods. If the driver refuses to wait then please mark the goods as damaged on the delivery note, so you are covered for all eventualities. If you have checked the goods and they are found to be damaged, please mark this clearly on the delivery note and contact our offices straight away.
If you are unavailable when your goods are delivered on your pre-booked delivery date, then re-delivery charges will apply. If you are unavailable when smaller packaged goods (eg. Stove Glass) are delivered, the courier company will leave a note, explaining how to re-arrange delivery for a more convenient time.
