Overview, Pros, And Cons
IgniteXL

Pictured: Dimplex IgniteXL 100" Built-in Linear Electric Fireplace
The Dimplex IgniteXL is the basic model that the Ignite Series offers. It features a slim profile with a depth of about 6” which is suitable for a 2x6 framed wall installation (using the optional trim kit).
It has the patented Multi-Fire® Flame Effect, which produces vivid and realistic flames. Additionally, the Comfort$aver® ceramic heater provides supplemental heating for up to 1,000 sq. ft. Aside from this, it uses 11% less energy than traditional quartz infrared heaters, which amounts to more savings on electricity bills. This can be hardwired to 120v or 240v.

Ignite Evolve

Pictured: Dimplex Ignite Evolve 74" Built-in Linear Electric Fireplace With Tumbled Glass and Driftwood Media
The Dimplex Ignite Evolve offers the same sizes, specifications, and dimensions as the IgniteXL Series. This means that you can easily replace your IgniteXL with the Evolve without any issues because the fit is identical.
It features ultra-realistic flames that are complemented by lifelike driftwood and multi-tonal tumbled glass media for a truly immersive fire experience. The Comfort$aver® technology delivers energy-efficient heating for up to 1,000 sq. ft., and the Multi-Fire XD Flame Effect creates vivid, customizable flames with seven theme options and five adjustable flame speed settings.
This fireplace integrates seamlessly into a 2” x 6” or 2” x 4” wall, and its edgeless design allows it to blend with various wall materials.

Ignite Bold

Pictured: Dimplex Ignite Bold 100" Built-in Linear Electric Fireplace
The Dimplex Ignite Bold offers a 12” deep ember bed that allows for larger logs, which come in standard with the unit. It features four installation options: front-facing, right or left corner, and bay-style, all customizable with removable side panels.
It has seven flame themes and five media color options, as well as three media modes: Prism, Kaleidoscope, and Midnight. It is compatible with the Flame Connect app, which enables endless customization using a smartphone.
The patented Dimplex flame technology creates realistic flames with a multi-layered color effect and adjustable speed. These can be complemented by a media bed of acrylic crystals and driftwood for an authentic fire appearance.
The Comfort$aver® technology provides supplemental heating for up to 1,000 sq. ft. Aside from this, it uses 11% less energy than traditional quartz infrared heaters, which amounts to more savings on electricity bills. This can be hardwired to 120v or 240v.
Technologically, the Bold uses standard 2D LED lighting combined with multiple spinning rods to create the flame effect. Reflections are utilized to enhance the depth of the firebox, giving the illusion that the logs are set further back in the flame, with the fire rising from the center. This stencil effect contrasts the bright flames and the dark background.

Flame Technology
Optiflame

Pictured: Dimplex Ignite Ultra 50" Built-in Linear Electric Fireplace
Optiflame is Dimplex’s original flame effect that was first launched in 1988. Instead of the common rolling LED lights, this technology uses LEDs that project upwards through a rolling stencil which forms the flame pattern. This technique enhances contrast, as the bright flames stand out against the dark background.
Heating Capabilities
Comfort$aver Heating

Pictured: Dimplex Ignite Bold 88" Built-in Linear Electric Fireplace
All Ignite Series models feature the patented Comfort$aver Technology, which is designed for energy-efficient heating. This system gradually supplements heat, allowing the fireplace to maintain a consistent room temperature. Aside from this, it uses 11% less energy than traditional quartz infrared heaters, which amounts to more savings on electricity bills. Additionally, these heaters are considered one of the best in the industry because it is powerful yet quiet.
All fireplaces under the Ignite Series can also be hooked to a 120v or 240v wire. These units output 5,000 (120v) to 8,500 (240v) BTUs, which is enough to heat up to 1,000 square feet of space. Plus, the Heat Boost feature allows the fireplace to quickly warm a room by temporarily operating at maximum output. You can also enjoy the beautiful flame effect year-round without heat.
Ambiance, Design, And Features
IgniteXL

Pictured: Dimplex IgniteXL 74" Built-in Linear Electric Fireplace
The IgniteXL features the patented Multi-Fire® Flame Effect, which produces vivid and realistic flame effects. It only offers orange flames with customizable ember bed colors. Yes, no speed adjustments are available. All adjustments can be made via the included remote control.
Its design features a reflective background that creates the illusion of flames rising from the center of the logs or rocks. Although the reflection helps with this illusion, using the fireplace in a place with lots of light or open windows can make the flames too bright.
Additionally, you can choose from different color themes or use the prism mode to cycle through colors and freeze on your favorite. The Multi-Fire XD® flame effect creates a realistic flame that can be enjoyed with or without heat, making it suitable for year-round use. The hidden backlit touch controls keep the design smooth and modern, and a remote allows you to adjust all the settings from anywhere in the room.
Ignite Evolve

Pictured: Dimplex Ignite Evolve 60" Built-in Linear Electric Fireplace With Tumbled Glass and Driftwood Media
The Dimplex Evolve is essentially an upgraded version of the IgniteXL series. It offers the same sizes, specifications, and dimensions, which means that you can easily replace your IgniteXL with the Evolve without any issues because the fit is identical. It features the patented Multi-Fire XD Flame Effect, which produces vivid and realistic flames similar to what you can see in a traditional fireplace. It also offers more customization options like 1-5 speed settings, more flame colors (blue, orange, neutral, neutral with orange and blue accents, neutral with orange accents, neutral with blue accents, orange and blue combined), ember bed colors, media accent lighting, and WiFi control.
You can also alternate between three media modes: Prism, Kaleidoscope, and Midnight. The Prism mode cycles through colors, the Kaleidoscope mode changes colors at different rates, and the Midnight mode turns the media and overhead lights off while reducing glare for TVs installed above the fireplace.
While logs are not included as standard, they are available as an upgrade. The unit has a framed appearance, and the top night light is less noticeable due to the unit’s deeper design. The slim firebox creates a more outward-facing flame. Visually, it appears closer to the viewer and brighter compared to the IgniteXL. This change in the firebox design also enhances flame contrast. Additionally, certain flame colors can make the flames appear larger, which fills the firebox more. This creates dynamic, rotating mood settings that cycle through various color options.
Lastly, its integrated smart self-diagnostic technology works seamlessly behind the scenes to help diagnose potential issues. When a problem arises, the system displays a specific error code on the LED screen. This code can then be shared with service providers or customer experience representatives, enabling them to quickly identify the issue and provide assistance in troubleshooting or ordering the necessary parts for repair.
Ignite Bold

Pictured: Dimplex Ignite Bold 74" Built-in Linear Electric Fireplace
The Ignite Bold offers all the features of the Evolve but with a different design. The patented Dimplex flame technology offers realistic flames with a new multi-layered color effect. It has 7 flame themes (blue, orange, neutral, neutral with orange and blue accents, neutral with orange accents, neutral with blue accents, orange and blue combined), 5 speed settings, 5 media color options (white, blue, violet, red, green), 3 media modes (prism, kaleidoscope, midnight), and WiFi + app control.
This model also boasts a true built-in design with taller glass, which creates a seamless and frameless appearance that extends beyond the bezel into the drywall. Its 12-inch depth accommodates a deeper ember bed, offering the flexibility to customize the unit with larger standard logs. This enhanced depth also amplifies the effect of the top night light, which shines down to brighten the overall aesthetic. The Bold further enhances versatility with removable corners, enabling an open-corner design for a more modern look. Additionally, tinted glass minimizes front reflection, delivering a clearer and more immersive view of the flames.
These reflections are utilized to enhance the depth of the firebox, giving the illusion that the logs are set further back in the flame, with the fire rising from the center. This stencil effect contrasts the bright flames and the dark background.

Ignite Ultra

Pictured: Dimplex Ignite Ultra 60" Built-in Linear Electric Fireplace
The Ultra model is the newest addition to the Ignite Series. It offers a more robust design and a variety of media options that come standard.
The patented Dynamic-Fire Effect is Dimplex’s brand-new flame effect that provides realistic flames for better ambiance. It also comes with quick connect and moveable Rhythmic Inner Glow Logs that glow and pulse in rhythm or with the crackling sounds.
Unlike the Ignite Bold, this unit only comes with 3 color options (orange, yellow, and light yellow). However, it still has adjustable flame speed and flame brightness, customizable ember bed and top-light colors, app and Wi-Fi control, and crackling sounds and glowing logs with adjustable colors via the app.
Installation Options
IgniteXL

Pictured: Dimplex IgniteXL 50" Built-in Linear Electric Fireplace

Ignite Evolve

Ignite Bold

Pictured: Dimplex Ignite Bold 50" Built-in Linear Electric Fireplace
The Ignite Bold features a true built-in design with taller glass, creating a frameless aesthetic that extends beyond the bezel into the drywall. It also offers four versatile installation options: front-facing, right or left corner, and bay-style, all customizable with removable side panels for a personalized look.
At 12 inches deep, this model includes a deeper ember bed, which allows for the customization of larger standard logs. Additionally, it is available in larger models, so the Bold can be coupled together using a coupling kit for expansive installations. You often see this setup in restaurants or commercial spaces.
Ignite Ultra

Pictured: Dimplex Ignite Ultra 88" Built-in Linear Electric Fireplace
The Ignite Ultra stands out with its flexibility because it offers numerous configurations to suit a wide range of design preferences. It can be installed as a single-sided fireplace for a classic look that emphasizes the flames. For a more dynamic aesthetic, the three-sided configuration allows flames to be viewed from multiple angles, making it ideal for open-concept spaces or as a divider between rooms. Additionally, it supports corner installations that are customizable for either left or right corners. For users who lose their remotes all the time, the Ignite Ultra offers a wall-mountable magnetic remote control.
Maintenance Requirements

IgniteXL & Evolve
The IgniteXL is low-maintenance. Clean the glass occasionally with a soft and non-abrasive cleaner to keep it clear. Check the air vents for dust to ensure proper airflow, especially when using the heat function. The long-lasting LED lights rarely need replacing.
Ignite Bold
The Ignite Bold requires slightly more attention due to its deeper design. Clean the glass regularly to keep the flames visible and check the ember bed for dust if using larger logs or media. Keep the air vents clear for smooth operation. Its sturdy build and long-lasting LEDs make it a low-maintenance choice overall.
Ignite Ultra
The Ignite Ultra is simple to care for, even with its flexible configurations. Clean the glass panels regularly, especially in three-sided setups, to keep the flames visible from all angles. Check the air vents for dust to ensure efficient performance. The LED lights are built to last and rarely need replacement.
Price Point

IgniteXL
The IgniteXL is the most affordable option in the series and has remained popular for nearly 10 years. With this price, you already get the best heater in the industry, some customization, and multiple sizes to accommodate your living space.
Ignite Evolve
The Ignite Evolve costs a bit more than the IgniteXL, but the extra features make it worth the price without a big jump in cost. In addition to the industry-best and quiet heater, you also get a lot more color customization options (flames speed, additional flame colors, media modes), WiFi control, and smart self-diagnostic technology.
Ignite Bold
The price increase from the Evolve to the Bold is significantly higher than the jump from the IgniteXL to the Evolve. However, investing a few hundred dollars more in the Bold could pay off in the long run, as the difference will make a huge difference 10 or 20 years down the road. Since this costs more, it guarantees added features like more installation options (front-facing, right or left corner, bay-style), multi-color flames, standard logs, and app control.
Ignite Ultra
The upgrade from the Ignite Ultra to the Bold is not that much, so it is up to you which aesthetic you like more. Its added features include different-looking flames, crackling sounds, and standard glowing logs that can be customized via the app.
Best Suited For
IgniteXL

Pictured: Dimplex IgniteXL 100" Built-in Linear Electric Fireplace
The IgniteXL model is best suited for those strictly on a budget because of its affordable price. Additionally, it is the basic version of the Evolve model, as it offers fewer features but still delivers reliable performance at a lower price point.
Ignite Evolve

Pictured: Dimplex Ignite Evolve 74" Built-in Linear Electric Fireplace With Tumbled Glass and Driftwood Media
The Evolve model builds on the foundation of the IgniteXL, bringing it up to 2024 standards with cosmetic and functional enhancements. Here, the flames appear brighter and more forward, resulting in a visually striking display. This makes the Evolve a solid, feature-rich unit for anyone seeking an upgrade without sacrificing performance.
Ignite Bold

Pictured: Dimplex Ignite Bold 100" Built-in Linear Electric Fireplace
If you want a fully built-in and frameless design, then the Bold model is for you. Its deeper ember bed and customizable options, like larger logs and removable side panels, make it great for homes, restaurants, or businesses looking for a stylish focal point. With multiple installation options, it works well in different layouts and adds a premium touch to any residential or commercial space.
Ignite Ultra

Pictured: Dimplex Ignite Ultra 100" Built-in Linear Electric Fireplace
The Ultra’s design is suited to those who prefer a fully built-in aesthetic, as the firebox (at 15”) provides a much deeper ember bed. This allows the flames to look more realistic and striking. While the price upgrade from the Bold is relatively modest, the choice between the two models largely comes down to personal preference in aesthetics. If you prefer a more traditional, linear look with brighter, yellow-toned flames and a more realistic log set, the Ultra is an excellent choice for you.
