The Gazco Onyx Avanti 150RW is a versatile electric fire designed to enhance your interior décor. With three size options, this electric fire can be configured in different ways to create a stunning focal point in your home. Whether you prefer a single-sided, two-sided corner, or three-sided design, the Onyx Avanti offers flexibility to suit your living space, combining the allure of a traditional log fire with modern technology through Chromalight® Plus technology.

This electric fire comes with convenient features such as a remote control for easy operation, allowing you to adjust temperature and flame settings from your sofa. The built-in thermostat ensures the room stays at a comfortable temperature, and you can also control the fire using the Avanti app on your iOS or Android smart device. With a 2kW heat output, the Onyx Avanti provides instant warmth, and the thermostat control feature allows you to set a desired temperature, automatically shutting off once reached.

For added ambience, you can enhance the look of the Onyx Avanti with the optional mood lighting system, which includes up to 6 meters of flexible LED strips. These strips can be installed around a TV or along shelves to create additional lighting effects in your living space, making the Avanti 150RW a stylish and functional addition to your home.

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.
