Product Description

Overview

The Dimplex Opti-Myst® Pro 1000 Built-In Electric Firebox (GBF1000-PRO) is a built-in electric fireplace designed to create a highly realistic flame display using patented water-vapor technology. By combining ultrasonic water mist with LED lighting, the system produces three-dimensional flames and smoke effects that closely resemble a real wood-burning fire. The firebox can be installed as a traditional front-view fireplace or converted into a see-through design by removing the rear panel, making it suitable for custom wall installations and modern architectural spaces.

Benefits

  • Supports single-sided or see-through installation for flexible design layouts.
  • Provides supplemental heating for rooms up to about 400 sq. ft.
  • Operates without gas lines or venting for simpler installation.
  • Creates a dramatic focal point for modern feature walls or room dividers.
