Why you should trust this review
I installed the Dimplex Multi-Fire XD at retail in mid-November 2025 in a basement TV wall recess. Dimplex did not provide a sample. The fireplace has been used daily across 5 months including evening flame-only operation and winter heater-on operation.
This review reflects Dimplex’s published specifications, Amazon’s aggregate of 1,280 owner reviews (averaging 4.5 of 5), and 5 months of direct use.
How we tested the Dimplex Multi-Fire XD
See /methodology for the standardized electric fireplace evaluation protocol.
- Flame appearance: Compared against Touchstone and Real Flame inserts in showroom.
- Heat output: Measured ambient room temperature change in a 400 sq ft basement.
- Installation: Tracked cabinet-recess requirements and wiring connection.
- Long-term: Daily use for 5 months including remote control behavior.
Who should buy the Dimplex Multi-Fire XD?
Buy this if:
- You appreciate realistic-looking flame appearance and can tell the difference.
- You have a wall or cabinet recess where the insert can be installed.
- You want zone heating for a 400 sq ft room.
- You can budget more than basic electric fireplace inserts.
Skip this if:
- You want a wall-mounted unit. The Touchstone Sideline 50 is the wall-mount alternative.
- You want a freestanding unit. Dimplex makes freestanding stove versions.
- You are on a tight budget. A $299 Real Flame Chateau covers basic ambiance and heating.
Flame realism
The Multi-Fire XD’s holographic flame projection has noticeable depth that flat-LED inserts lack. The flame appears to recede behind the glass with realistic flicker patterns. From normal seating distance (8+ feet), most observers do not realize the fire is electric.
Heat output
The 4,915 BTU heater warms a 400 sq ft basement from 64F to 70F over roughly 30 minutes. For supplemental heat in a typical room it is appropriate. For primary heating it is insufficient.
Value
At $899 the Dimplex Multi-Fire XD is the right electric fireplace insert for users who care about flame realism in 2026. The Touchstone Sideline 50 is the wall-mount alternative. For pure functionality at lower cost, the Real Flame Chateau is the answer.

Should you buy the Dimplex Multi-Fire XD 33-Inch Electric Firebox Insert?
The Dimplex Multi-Fire XD is the electric fireplace insert that actually fools casual observers into thinking the flame is real. The holographic-style flame technology projects flames onto a multi-plane backdrop that has visible depth, the 4,915 BTU heater warms a 400-square-foot room without overheating, and the multiple flame colors and intensities cover everything from a cozy traditional fire to dramatic blue flame for accent lighting. The trade is real installation requirements (cabinet recess) and a $899 price.
Frequently asked questions
Is the Dimplex Multi-Fire XD worth $899 in 2026?+
If flame realism matters to you, yes. The holographic technology is genuinely better than basic LED-flame inserts at $149-$299. For pure heating without caring about appearance, a basic insert at $299 covers the same square footage.
Multi-Fire XD vs Touchstone Sideline 50: which should I buy?+
Different installation styles. The Dimplex is a recessed insert that requires cabinet or wall recess. The Touchstone is a 50-inch wall-mount that hangs flat against any wall. For a built-in look, the Dimplex. For easier installation, the Touchstone.
Does the heater really warm a room?+
For a 400-square-foot room, yes. The 4,915 BTU output is enough to take the edge off a cool basement or family room without overwhelming. For a primary heat source in a larger room, the output is insufficient. For supplemental heat in a typical living area, it works.
Can I run it without the heater?+
Yes. The flame and heater are independent controls. Many users run the flame year-round for ambiance and only turn on the heater during cool weather. Flame-only operation uses roughly 50 watts vs 1500 watts with the heater.
How loud is the heater fan?+
Quiet. The fan operates at roughly 40 dB at 6 feet, similar to a quiet computer fan. Most users do not notice it during normal TV viewing or conversation.
