What it has going for it

What changes in your evenings

45 in wide, per the listing. Wide enough to be the focal point of a living-room wall. Check in the installation drawing whether the figure is the frame or the viewing area, then hold it against your wall cavity.

Flame without heat. The heater and the flame run separately, so you can have the glow in July without warming the room. The fireplace earns its place all year, not only in January.

Thermostat. Set a temperature and the heater cycles on its own instead of running flat out until you remember to turn it down.

Living room or bedroom?

For a bedroom or a study, the thermostat holds the temperature instead of baking the room. The flame runs without heat, so it can glow on a warm night too.

On balance it is happiest in a bedroom, a study or a cosy corner.

Great for you if…

You want the glow all year, heat or no heat
You hate fiddling with the heat

Skip it if…

You want the heater output stated: the listing we read gives no wattage or BTU figure
You'd rather wait for buyer reviews: none are captured for this listing yet
You want to run it from your phone: the listing names no app or WiFi

Price and cost per inch of width

$1,279.99 Price on Sep 30, 2026 · may have changed

At the price on Sep 30, 2026, each stated inch of width costs about $28. That puts it in the pricier third of the 117 inserts we have a price for.

Cost per inch is only a rough yardstick: the heater, the flame options and the build count as much as the width.

Our take

The verdict

Our favourite thing about the Dimplex BF45DXP 45" Deluxe Firebox is 45 inches of fire across the wall, closely followed by a flame that runs without the heat. No buyer reviews yet, so the Dimplex BF45DXP 45" Deluxe Firebox has to win you over on paper. The catch with the Dimplex BF45DXP 45" Deluxe Firebox: no heater output in the listing, while most picks here state one. We'd pick it if you want the glow all year, heat or no heat; otherwise, put it next to the Amantii Panorama Xtraslim Lumina first.

Living with it

Delivery day

A big, flat box with glass inside: open it with two people and check the front before the cardboard goes out.

The first evening

Try the flame at a few brightness settings; lower often looks more real at night.

Day to day

The thermostat set once, and a quick dust of the glass now and then. Our maintenance guide has the rest.

Summer

Heater off, flame on: the glow stays on the wall in July without warming the room.

The one thing we'd check first

Before you order the Dimplex BF45DXP 45" Deluxe Firebox: check your wall, because the 45-inch figure has to match your opening, and a listing width can mean the frame or just the viewing area.

Before you buy

Your wall

Draw the opening on the wall with painter's tape at the real size, step back, and check it against the installation drawing. Our recessed installation guide lists the clearances to ask about.

The outlet

Pick the outlet before you pick the finish: a free one close by, nothing heavy on the same circuit, and no extension cord. Our power requirements guide lists the questions to ask.

Heat for your room

Treat it as supplemental heat for one room. Our supplemental heat planner turns your square footage into a rough answer.

Delivery and install

Glass-fronted inserts are big, flat boxes: plan two people for the unboxing, and decide early who frames the wall. Our built-in vs wall-mounted guide weighs recessed against wall-mounted.

Frequently asked questions

Is the Dimplex BF45DXP 45" Deluxe Firebox any good?

We rate it 5.9/10 (fair). The rating comes from its documented listing alone, as no customer-review record is captured yet.

What size and heater output does the Dimplex BF45DXP 45" Deluxe Firebox state?

Its listing states a 45-inch width and recessed (in-wall) installation. Those are the maker's figures, so check in the installation drawing whether the width means the frame, the firebox or the opening. The listing we read gives no heater figure, so ask the seller before you count on it for warmth.

What power supply does the Dimplex BF45DXP 45" Deluxe Firebox need?

The listing we read does not state its supply voltage or heater wattage. Read the supply, plug and circuit conditions on the exact listing and in the manual before you order, and never run a heater on an extension cord or a shared power strip. Anything beyond an existing standard outlet, hardwiring or 240 V included, is a job for a licensed electrician.

What do you get with the Dimplex BF45DXP 45" Deluxe Firebox?

Its listing states a 45-inch width, a flame that runs without the heat and a thermostat. Those are the seller's figures; for how real the flames look in a living room and how loud the fan runs at night, the buyer reviews are the better guide.

What should I check before ordering the Dimplex BF45DXP 45" Deluxe Firebox?

Your wall: draw the opening on the wall with painter's tape at the real size, step back, and check it against the installation drawing. Our recessed installation guide lists the clearances to ask about. The outlet: pick the outlet before you pick the finish: a free one close by, nothing heavy on the same circuit, and no extension cord. Our power requirements guide lists the questions to ask. Heat for your room: treat it as supplemental heat for one room. Our supplemental heat planner turns your square footage into a rough answer. Delivery and install: glass-fronted inserts are big, flat boxes: plan two people for the unboxing, and decide early who frames the wall. Our built-in vs wall-mounted guide weighs recessed against wall-mounted.

Where can I buy the Dimplex BF45DXP 45" Deluxe Firebox?

We link to the exact listing on Amazon, where today's price, stock and seller apply. It is an affiliate link, and it has no effect on the rating.
