Flame effect can be used independently of heat Optiflame® is the world’s most popular electric flame effect, and can be found in a wide selection of Dimplex fires. It is a unique, patented means of generating realistic simulated flames from an electric source and creates the illusion of flames emanating from the centre of an enhanced depth fuel bed to provide a realistic glow that can be enjoyed throughout the whole year. Dimplex revolutionised the fires market when we launched the first Optiflame® effect in 1988 and since then Dimplex have consistently refined and improved it to the level of perfection that you see today. As a result, they have won numerous awards for their fires and they have also been selected to feature on a number of mainstream TV home interest programmes and in feature pieces at home interest shows.
