Product detail
Create the look and warmth of a traditional fireplace without gas, wood, venting, ash, or open flame with the Dimplex 45 Inch Deluxe Built-In Electric Firebox. Designed for custom mantels, built in fireplace surrounds, remodels, and classic hearth installations, the BF45DXP delivers realistic electric fireplace ambiance in a large, elegant firebox format.
With patented Inner Glow Logs, a brick look interior, supplemental heat, and flame only operation, this UL Listed electric firebox is ideal for homeowners who want the character of a traditional fireplace with the clean convenience of electric performance.
The Dimplex BF45DXP is built for rooms where the fireplace needs to feel substantial, permanent, and refined. Its 45 inch size creates a larger hearth presence than smaller electric fireboxes, making it a strong choice for living rooms, great rooms, family rooms, dens, and custom fireplace walls.
The built in design allows the firebox to be recessed into a framed wall, installed inside a custom mantel, or used as part of a more traditional fireplace surround. This gives the room the appearance of a real masonry fireplace without the installation complexity of combustion based systems.
The BF45DXP features Dimplex flame technology paired with patented Inner Glow Logs. The individually molded logs are designed to glow from within, creating the look of natural burning wood and adding depth to the flame presentation.
Combined with the brick look interior, the fireplace creates a warm and familiar hearth experience that works beautifully in traditional, transitional, and luxury residential interiors.
The Dimplex 45 Inch Deluxe Built-In Electric Firebox supports 120V, 208V, and 240V installation, allowing heating performance to be matched to the project. Depending on voltage, the unit can provide approximately 4,915 to 9,220 BTUs of supplemental heat.
This makes the BF45DXP a strong option for homeowners who want both visual ambiance and functional room comfort from a built in electric fireplace.
The flame effect can operate with or without heat, allowing you to enjoy the fireplace throughout the year. Use the heater during cooler seasons, or run the flames on their own when you want the relaxing glow of a fireplace without adding warmth to the room.
This flexibility makes the BF45DXP useful as both a heating feature and a design feature.
The BF45DXP is designed for direct wire built in installation, creating a clean finished appearance without visible cords. Select installations may also use an optional plug kit, depending on the electrical setup and project requirements.
For luxury remodels, custom mantels, and professional fireplace builds, this firebox provides a dependable electric alternative to wood or gas.
The Dimplex BF45DXP is ideal for homeowners who want a larger traditional fireplace look without the maintenance or installation demands 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 custom fireplace surrounds, large mantels, remodel projects, and upscale living spaces, the BF45DXP delivers classic hearth character with modern electric convenience.
The Dimplex 45 Inch Deluxe Built-In Electric Firebox brings classic fireplace styling, realistic electric flames, supplemental heat, and clean built in installation together in one large format indoor fireplace solution.
