Buying guide
Dimplex Ignite Ultra
vs Ignite Bold
Glowing logs, crackling sound and two flame effects. Decide what the upgrade is worth to you.
The decision
Choose the fire you want to look at every evening.
Dimplex Ignite Ultra earns its place when illuminated logs, crackling sound and a choice of physical flame effects are central to your fireplace. Dimplex Ignite Bold is the stronger starting point when you want a customizable linear display with driftwood and crystals, without giving up front, corner or bay installation possibilities.
We would not choose Ultra for more heater power or app access alone. In these 50-inch models, both offer 1,500 watts at 120 volts or 2,500 watts when correctly hardwired at 240 volts, and both support FlameConnect. The worthwhile upgrade is the presentation—and whether your wall can accommodate it.
Start with Ignite Ultra if…
You want the logs themselves to glow, sound to be part of the experience and the option to select Dynamic-Fire or Multi-Fire during setup. You are planning the surround around the appliance, rather than trying to preserve a shallow existing cavity.
Start with Ignite Bold if…
You like its driftwood-and-crystal composition and want to adjust themes and speed without making a physical flame-system choice. You may also be planning a sheltered outdoor location: Bold has specific outdoor instructions, while Ultra’s manual prohibits outdoor use.
See the difference
Watch the logs as well as the flames.
Ultra changes more than the color of the fire. Its supplied inner-glow logs pulse with the presentation, adding another illuminated layer below the flames. Bold’s standard package combines driftwood with small, large and extra-large crystals. Both include a complete decorative-media package. Optional media is a matter of the look you prefer.
Ultra’s Flex-Flame choice deserves a little attention before installation. Dynamic-Fire uses the installed flicker rod; the included alternative rod produces Multi-Fire. That is a component change, separate from selecting a theme with the remote. If your preference is clear from the films, decide it before the surround is completed.
What the upgrade changes
The differences worth paying attention to.
| What changes | Ignite Ultra 50-inch | Ignite Bold 50-inch |
|---|---|---|
| Standard media | 6 inner-glow logs, glass embers, gravel and glass chunks | 6 driftwood pieces, small crystals, 5 large and 3 extra-large crystal pieces |

| Framed opening W × H × D | 50¾ × 28 × 15 in. | 49½ × 24¼ × 11⅝ in., with the manual’s ½-inch drywall framing basis |
| Heat at 120 / 240 volts | 1,500 / 2,500 watts | 1,500 / 2,500 watts |

The Ultra example needs a framed cavity 3⅜ inches deeper and 3¾ inches taller than this Bold example. Those differences are calculated from the listed framed openings—not from the nominal 50-inch name. Even before finishes are considered, this is a different wall-planning decision. The overall appliance dimensions are different again: the 50-inch Ultra is 54⅝ inches wide overall, while the 50-inch Bold is 50½ inches wide. Use the correct framing and finished-face drawings together rather than measuring only the opening or assuming the nominal name describes the full width.

Our take on Dimplex Ignite Ultra
We like Ultra when the fireplace is being designed as a main feature of the room. Glowing logs, sound and the choice of flame system give the premium a specific purpose. The deeper enclosure is part of that decision: allow for it before falling in love with a finished-room photograph.
If you normally prefer a quiet, restrained background fire, you may not use everything Ultra adds. Its value is strongest when its layered display is the reason for the project.

Our take on Dimplex Ignite Bold
We would keep Bold firmly in the comparison. Bold already gives you open-sided installation, adjustable themes, app support and dual-voltage heating. Those shared features make it a well-equipped choice in its own right.
Bold is also the relevant one of these two for a sheltered outdoor project that meets its instructions. Paying more for Ultra would not solve that requirement.

What owners say
Owners highlight the modern appearance and the option to expose or enclose the glass sides. Another appreciates the fireplace both switched on and as a feature in the room when off. Those accounts reinforce the importance of the finished installation: the shape and viewing angles are a large part of Bold's appeal, not just its flame settings.
Plan the complete wall
The same nominal width does not mean the same opening.
Mark the actual framed opening, visible sides and finish thickness on the drawing. Both fireplaces offer several viewing arrangements, but the side-panel, glass and finishing steps depend on which sides will remain open. Neither appliance supports the weight of the wall above it.
Choose the electrical arrangement with the installer. Both examples can operate at 120 volts; a suitable 240-volt hardwired installation increases the listed heat output. The higher-voltage option is a supply and wiring decision, not an app setting. Flame-only operation remains available when the room does not need warmth.
For app use, check Wi-Fi coverage at the intended fireplace location before the wall is closed. Ultra also supplies a Bluetooth remote with a magnetic wall mount; you do not need to make a phone the household’s everyday control.
If you are considering a covered patio, use Bold’s outdoor instructions for shelter, electrical protection and service requirements. Ultra’s indoor-only restriction is a selection difference, not a small-print detail to discover after ordering.
What arrives
The flame display comes with its decorative media.
Ignite Ultra 50-inch
- 6 illuminated inner-glow logs plus the supplied ember/glass/gravel collection
- Installed Dynamic-Fire rod and supplied alternative Multi-Fire rod
- Bluetooth remote with wall mount and plug kit
- Front and side glass, mounting and finishing components listed in the manual
Ignite Bold 50-inch
- 6 driftwood pieces and the supplied crystal collection
- Remote control and the model’s standard glazing and mounting equipment
- The installation instructions for the chosen visible-side arrangement
A finished fireplace still needs its suitable surround, electrical work and installation. Compare that complete project alongside the live appliance prices. Optional rocks or other media should be chosen against the exact model’s guidance rather than treated as required extras.

Confidence in the purchase
Five-year indoor coverage on both.
Both manuals provide five-year limited coverage for the fireplace in an eligible indoor installation, including on-site or in-home service for covered claims under the terms. That is a meaningful shared ownership benefit; it is not a reason to assume the more expensive model has a longer indoor term.

Good questions
A clearer choice.
Does Ignite Ultra have a more powerful heater than Ignite Bold?
Not in the 50-inch configurations compared here. Both list 1,500 watts at 120 volts and 2,500 watts at 240 volts. Installation, room conditions and the chosen electrical supply still matter.
Can I change Ultra from Dynamic-Fire to Multi-Fire with the remote?
The physical effect uses a different flicker rod. Ultra includes the alternative rod with its installation instructions. Remote theme, brightness and speed adjustments are separate controls.
Do both fireplaces offer corner and bay installations?
Yes. Both manuals provide viewing-arrangement instructions. Check the exact size’s framing and finishing requirements; the two 50-inch models do not share the same opening.
Is the app exclusive to Ultra?
No. Both support FlameConnect. Ultra’s supplied Bluetooth remote and app functions should be considered alongside its illuminated logs, sound and physical flame options—not treated as proof that Bold lacks connected control.
