FireFX Atmos 135R Electric Fire

The FireFX Atmos 135R Electric Fire is a beautifully slim insert designed to become the centrepiece of any modern living space. Built for contemporary feature walls, it delivers the cosy character of a real flame without the upkeep of a traditional fireplace. With deeply realistic visuals and fully adjustable lighting, it lets you set the perfect mood at the touch of a button. If you want a flawless built-in finish, this is one of the most striking media wall electric fires in our range.

Designed for media walls

The Atmos 135R is engineered to recess neatly into a stud wall, with an integrated frame that hides any small gaps or imperfections for a clean, professional result. At just 140mm deep, it sits comfortably within a standard partition, measuring 1350mm wide and 450mm high overall, so you can plan your aperture with confidence. Because it runs on electricity, there is no flue or chimney required, which simplifies installation considerably. Always leave adequate clearance above the unit if you intend to mount a television, following the heat output guidance and your TV manufacturer's recommendations.

Flame realism and control

The Atmos uses LED technology to recreate the gentle glow and dancing flicker of a genuine wood fire. Faux logs sit on a bed of blackened glass media, with embedded lighting that makes the logs appear to softly smoulder. You can choose from five flame colours and five brightness settings, plus a fuel bed offering 13 colour options and a dynamic spectrum mode to match your décor. Best of all, the flame effect can be enjoyed independently of the heat, so you can run it through summer evenings as easily as winter nights, all managed by the supplied remote control.

Heat and running cost

When you want warmth, the thermostatic heater keeps your room at a comfortable, steady temperature. Running the heater at full output of roughly 2kW would cost in the region of 50p per hour, based on a UK electricity price of around 25p per kWh in late 2025. Using the flame effect alone costs only a few pence per hour, making it an affordable way to enjoy ambience year round. Smart features such as open window detection and Eco design compliance help keep running costs sensible, while the cool glass surface adds peace of mind.
