They're all built-in linear fireboxes; the differences are flame presentation, depth and shape. IgniteXL is the core range with edge-to-edge glass and the patented Multi-Fire XD flame. Evolve uses the same Multi-Fire XD system in a slim 5-3/4" deep profile that fits flush in a stud wall. Ultra is the top of the range, with the Dynamic-Fire flame effect, Rhythmic inner-glow logs that pulse with the ember bed and crackling sound options — but it is 14-1/2" deep, so it needs a 2x6 wall or a chase. IgniteXL Bold is the multi-sided version, built for corner, bay and peninsula walls where the fire is seen from two or three sides. If you're comparing two specific models, ask us and we'll put the spec sheets side by side.

Dimplex uses short codes that are easier to match than the marketing names. IgniteXL runs XLF50, XLF60, XLF74 and XLF100 by width. The Bold multi-sided models carry an XD suffix — XLF5017-XD, XLF6017-XD, XLF7417-XD, XLF8817-XD, XLF10017-XD. Evolve runs EVO50 through EVO100, Ultra runs ULT50 through ULT100, and the Aspire fireboxes are ASP30, ASP36, ASP42 and ASP48. The Optimyst water vapour linears are OLF46-AM, OLF66-AM and OLF86-AM. Every product page here lists the code, so you can match a quote or a spec sheet exactly.

It depends on the look you want. Revillusion is a traditional firebox with Realogs® logs and a reflective flame panel that makes flames appear to rise from within the logs — the right answer when you want a classic framed hearth. Ignite Aspire is a tall, portrait-shaped built-in firebox with a three-sided viewing area, shaped like a gas firebox rather than a linear slot. The linear ranges are wide, low bands of flame designed to be recessed into a framed wall, usually as a feature or media wall. Different jobs, not better and worse.

One thing worth knowing: Aspire and Revillusion are built-in fireboxes, not inserts. They are framed into a wall or new enclosure rather than slid into an existing masonry fireplace. Send us your opening dimensions and we'll tell you honestly what fits.

No — it's a different technology. Optimyst makes its flame from ultrasonic water mist lit from within by LEDs, rather than light reflected off a mirror, so the flame has real three-dimensional movement and a smoke-like drift. The Optimyst Linear models (OLF46, OLF66, OLF86) also include a fan-forced heater, while the smaller cassettes and the e-MatriX produce flame effect only with no heat — check the specification on the product page before you choose. Optimyst units need a water supply: the linears are designed to be hard-plumbed with 1/4" tubing, and the cassettes can be filled manually or plumbed.

It varies by model and configuration — some run from a standard plug-in circuit, others are direct-wired and need a dedicated circuit, and several offer 120V or 240V operation with different heat output at each. Settle this before the wall is framed and closed, not after. Our guide to electric fireplace electrical requirements covers what to hand your electrician, and we'll confirm the exact figure for the model you choose.
