The Celsi Ultiflame Ultra SL Adonis Electric Fire is where classic cast iron design meets modern flame technology. With its distinctive curved fascia in a sleek black finish, this stylish inset fire makes a bold statement in any fireplace while offering a depth-defying flame effect that looks every bit as realistic as a genuine log fire.
Slimline Design for Easy Fitting
Specifically engineered with a slim 70mm inset depth and 40mm spacer, the Adonis is perfect for homes that need a space-saving solution without compromising on style or performance. Its glass-fronted design brings a clean, contemporary edge, allowing the flames and fuel bed to take centre stage.
Stunning Flame Visuals
Powered by Ultiflame’s advanced projection system, this fire creates a layered flame effect that dances naturally across a Living Ember Bed. The combination of Natural Oak logs and wood chips enhances the authenticity, while adjustable flame speed and LED brightness let you fine-tune the display. With 16 colour presets plus an Animation mode, you can change the look of your fire to suit your mood, season, or décor.
Efficient Heating with Smart Control
The Adonis provides a variable 0.75kW / 1.5kW heat output, ideal for quickly taking the edge off a chilly evening. A thermostatic remote handset makes it easy to manage the heat and flame settings, while smart integration takes convenience even further. With the Celsi App (iOS & Android), or via Amazon Alexa and Google Assistant, you can operate the fire directly from your phone, tablet, or by simple voice command.
Built to Impress
The cast iron fascia gives the Adonis a strong, traditional presence, perfectly framing the contemporary flame effects. It’s a fire that doesn’t just warm your room but also enhances it, delivering atmosphere, efficiency, and elegance in equal measure.

Due to the continuing rise in costs for delivery to Highland areas, we have reluctantly concluded that having absorbed these costs for a long time
this is regrettably no longer possible and we have had to introduce a fee for delivery to certain Scottish postcodes. Customers that live in the affected
areas will be contacted when we process your order to be advised on specific extra charges and have the opportunity to confirm the order.
