Dimplex Juneau XL Multi Optimyst Fireplace Insert – Authentic Flame, Effortless Ambience

The Dimplex Juneau XL Multi Optimyst Fireplace Insert brings the mesmerising beauty of a real flame to your home without smoke, soot, or maintenance. Powered by Dimplex’s patented Optimyst® technology, it uses fine water vapour and LED lighting to create an astonishingly realistic three-dimensional flame and smoke effect. The result is a lifelike, flickering fire that adds warmth and atmosphere to any interior – all without producing heat.

Designed for flexible installation inside existing mantels, fireplace openings, or bespoke surrounds, the Juneau XL is ideal for larger spaces where a bold visual statement is desired. Its versatile, freestanding design allows easy placement and seamless integration into both modern and traditional interiors. With no heat output or chimney required, it provides a safe and captivating flame effect suitable for use all year round.

Flame effects can be customised to suit your mood, with adjustable brightness and a choice of colours including amber, blue, violet, and aquamarine. Using the Flame Connect app or the included remote control, you can tailor the look and intensity of the flames and even add a subtle crackling sound for extra realism. The front-access water drawer makes refilling quick and convenient, delivering up to ten hours of continuous operation per fill.
