More information about Optimyst Electric Fireplace


What Is an Optimyst Electric Fireplace?

An Optimyst electric fireplace is one of the most realistic alternatives to a traditional wood-burning fire – without smoke, soot or mess. Developed by Dimplex, Optimyst uses ultrasonic technology to create a fine water mist that rises and reflects light, forming convincing, three-dimensional flames and smoke effects.

Unlike flat LED-only displays, Optimyst creates depth, movement and glow that feels almost indistinguishable from the real thing. It’s a perfect solution for British homeowners who want a real-fire look with none of the hassle. Just add water, plug it in, and enjoy the magic of mist-based flame effects in your living room, bedroom or media wall.

Why Choose an Optimyst Electric Fireplace

British homeowners love Optimyst fireplaces for their lifelike performance and safe, mess-free design. Key benefits include:

  • 3D flame and smoke effect created by ultrasonic water vapour
  • Flame without heat for year-round ambience
  • Safe to touch – perfect for homes with children or pets
  • No chimney, gas or ventilation required
  • Easy installation – freestanding, wall-mounted or inset
  • Energy-efficient LED lighting combined with water mist
  • Top-quality craftsmanship from trusted UK brand Dimplex

This makes Optimyst ideal for both modern and period homes across the UK – whether you're renovating a fireplace recess or upgrading a blank wall.


A Realistic Fire Experience Without the Drawbacks

Unlike other electric flame technologies, Optimyst mimics the depth and movement of a real fire using actual mist. The result is a swirling flame that rises and shifts like real combustion – but with no risk of burns, sparks or fumes.

All you need is a standard UK plug and regular tap water. The built-in reservoir provides hours of operation, and many models include adjustable flame height, lighting intensity, and remote control. You get the feeling of a log-burning fire with the ease of electric operation.

This makes Optimyst fireplaces perfect for UK homes that want atmosphere without the commitment, cleaning or building work required by traditional options.

Available in a Range of Styles and Sizes

Optimyst electric fireplaces come in a wide variety of formats to suit different spaces and tastes. Choose from:

  • Inset cassette fires to fit existing fireplaces or bespoke builds
  • Freestanding Optimyst stoves for a traditional cottage look
  • Wall-mounted units for modern interiors
  • Double-sided and open-view fires for room dividers or feature walls
  • Optimyst media wall suites with integrated shelving or TV space

Whether you're furnishing a compact city flat or a large country home, there's an Optimyst model that will elevate your room with warmth, realism and elegance.

Low Maintenance, High Impact

Operating an Optimyst fireplace is as easy as filling the water tank and pressing a button. No wood, no ash, no servicing – and no permanent installation required. The mist is odourless and clean, and the units are designed with energy efficiency in mind.

Many models also include:

  • Thermostat and heat settings
  • Timer function
  • Remote control or smart compatibility
  • Flame-only mode for summer evenings
  • Water level indicators and auto shut-off

This makes Optimyst fireplaces one of the most advanced and convenient electric fireplace options on the UK market today.
