The Dimplex Optimyst Cassette 1000 Retail Multi is a premium, built-in electric fire that gives you complete creative freedom for your dream fireplace. Measuring 1 metre wide, it’s perfect for large, bespoke installations such as media walls, contemporary room dividers, or panoramic feature fireplaces that become a striking focal point in any home.

Unlike conventional electric fires, the Cassette 1000 has no fixed fascia or trim, allowing it to be recessed into a custom opening. Whether used as a one-sided feature, see-through tunnel fire, or a 360° multi-view installation, this versatile cassette adapts perfectly to your design vision.

At its core is Dimplex Optimyst flame technology, combining ultra-fine cold water mist with energy-efficient LEDs. The result is an incredibly realistic 3D flame and smoke effect that rivals a real wood fire, without emissions, mess, or safety concerns.

The Flame Connect app allows you to change flame colours from warm amber and red to aquamarine, violet, or dynamic mixed tones. Coupled with crackling log sound effects and adjustable volume, the Cassette 1000 creates a multi-sensory fireside experience.

The front-loading water tank provides 8–10 hours of continuous flame effect, and multiple cassettes can be linked to create extended wall-spanning flames. The optional log set adds a natural, traditional look if desired.

Adjust flame colour, intensity, sound, and lighting via the Flame Connect app or included remote control, giving you complete flexibility to personalise your ambience.

The Dimplex Optimyst Cassette 1000 Retail Multi is the ultimate solution for bespoke, modern electric fireplaces, delivering unrivalled realism, versatility, and style for your home.

Please note: The Dimplex Optimyst Cassette 1000 Project Multi is a decorative electric fire only and does not include a heater.
