Dimplex DFI400LH Opti-myst Electric Fireplace Cassette with Heat Receptacle



Dimplex DFI400LH Cassette can be used to build a custom fireplace or as an insert into an existing fireplace.

Revolutionary ultrasonic technology is used to create the flame and smoke effect of the Dimplex® Opti-myst® DFI400LH. As the mist rises up through the curved plate, the light reflects against the water molecules creating a convincing illusion of flames and smoke. The result is an appearance so authentic it will be mistaken for a true wood-burning fire.

This attractive water vapor insert can be used with or without a heater (sold separately), which can provide warmth for spaces up to 400 square feet. The unit plugs into a standard outlet and consumes 200-Watts per hour.
