Product detail
Add classic fireplace warmth and clean electric convenience to your home with the Dimplex 33 Inch Deluxe Built-In Electric Firebox. Designed for built in fireplace surrounds, custom mantels, remodels, and traditional hearth installations, the BF33DXP delivers the look of a real firebox without gas lines, venting, wood, ash, or open flame.
With realistic flames, patented Inner Glow Logs, a brick look interior, supplemental heat, and year round flame only operation, this UL Listed electric firebox is a strong choice for homeowners who want the character of a traditional fireplace with the simplicity of electric performance.
The Dimplex BF33DXP is designed to bring the appearance of a traditional masonry fireplace into modern homes. Its 33 inch size, realistic log set, and brick look interior create a familiar hearth style that works beautifully in living rooms, family rooms, bedrooms, dens, and custom fireplace walls.
Because it is built for recessed installation, this electric firebox can be framed into a wall, installed inside a custom mantel, or used to upgrade spaces where a combustion fireplace is not practical.
The BF33DXP uses Dimplex flame technology to create a realistic electric fire appearance with depth, movement, and warm visual ambiance. The patented Inner Glow Logs are individually molded and hand finished, then designed to pulse and glow from within for the look of natural burning logs.
This gives the fireplace a more authentic hearth presentation than a basic electric heater, making it a strong fit for spaces where the fireplace needs to feel warm, classic, and permanent.
The Dimplex 33 Inch Deluxe Built-In Electric Firebox offers flexible heating performance based on the electrical setup. It can be installed on 120V, 208V, or 240V, with heat output ranging from approximately 4,915 BTUs to 9,220 BTUs depending on voltage.
This makes the BF33DXP suitable for supplemental zone heating and, with 240V installation, it can provide stronger heat output for larger rooms or spaces where additional warmth is desired.
The flame effect can be used with or without heat, allowing you to enjoy the look of a fireplace throughout the year. Use the heater during cooler months, or run the flames on their own when you want the cozy glow of a fire without warming the room.
This year round flexibility makes the BF33DXP ideal for homes where design, comfort, and daily atmosphere all matter.
The BF33DXP is designed for a clean direct wire installation into a dedicated circuit. This creates a seamless built in appearance without exposed cords, making it ideal for custom fireplace surrounds and professional remodel projects.
An optional plug kit is available for select 120V installations, giving homeowners and installers additional flexibility depending on the project requirements.
The Dimplex BF33DXP is ideal for homeowners who want the timeless look of a built in fireplace without the complexity of gas or wood. It offers a realistic flame effect, glowing log set, brick look interior, and flexible heat output in a clean electric firebox designed for permanent installation.
For remodels, custom mantels, traditional fireplace surrounds, and rooms where a combustion fireplace is not practical, the BF33DXP provides a reliable way to add warmth, atmosphere, and classic hearth character to the home.
The Dimplex 33 Inch Deluxe Built-In Electric Firebox brings classic fireplace styling, realistic electric flames, supplemental heat, and clean built in installation together in one dependable indoor fireplace solution.
