1. Where the fireplace sits in the room
The XL is made to disappear into a flat wall, usually under a TV. You see it from the front.
The Bold has glass on the front and both ends. Built into a corner, it shows fire along two walls. Built as a bay, it projects from the wall and is visible from three directions. It can also be installed front-facing if you want the taller glass without the side views.
2. The wall it needs
This is the practical difference. The XL is under 6 in. deep and frames at 5 1/2 in., so it fits flush in a 2x6 wall. The Bold is 12 1/8 in. deep and almost 24 in. tall, so it needs a chase, a bump-out or a purpose-built enclosure. Framing for the Bold depends on whether it is a front, corner or bay install, so take it from the Dimplex installation guide; we can send the detail for your layout.
3. Heat
Both have the same heater, and it does not change with size. Neither is a reason to choose one over the other. See our electrical requirements guide.
4. Price
At 74 in. the Bold costs about $1,900 more than the XL. The Bold's enclosure is also more work to frame and finish, because up to three faces are exposed.
Which should you choose?
- Choose the Ignite XL if the fireplace is going flush into a flat media wall and will be seen from the front. Read the Ignite XL 74 review or see the XL 74.
- Choose the Ignite XL Bold if it is going in a corner, a bay or a wall that projects into an open plan, or you want a taller fire. See the XL Bold 74.
If you want a three-sided gas fireplace instead, compare the options in see-through vs peninsula.
