Who Is This For?

Dimplex Clement Optiflame

The electric fireplace electric inset fire is aimed at people planning an inset, media wall-style installation with a realistic-looking flame display. It is designed for a 9 cm inset (recess) depth, making it a sensible fit where installation space is limited. Heat output is adjustable with a 2 kW fan heater, including 1000 W and 2000 W settings for milder days and colder rooms. It also suits buyers looking for a black LED flame effect fireplace with a logs-style appearance. Depth is fixed for this model, so it is not ideal where a deeper recess is required.

KAMINIO HENRI

The electric fireplace suits people who want the look of an electric stove, with a log-burner style front and room control via a remote. It fits households looking for a straightforward electric fireplace setup because it includes an electric heater and a flame effect, plus LED mood lighting.
