Dimplex Deluxe Series

The Deluxe carries the fuller feature set, including the trim and glass options that let it finish flush in a finished wall. If the firebox is going into a visible, finished opening rather than a utility space, that difference is the one that shows.

Measure the existing firebox opening at the front and choose the model that fits inside it with clearance. If you are framing a new opening instead, build to the manufacturer's dimensions rather than to the firebox's outside measurements.

A firebox. It is the insert that produces the flame and heat; the surround, mantel and finish are yours. That is what makes it flexible in a remodel, and it is also why the finished cost is not just the firebox price.

Roughly 4,915 to 9,222 BTU depending on model and setting. Supplemental heat for the room it faces, not a primary heat source.

Check the model's electrical requirement before framing, because it varies with the heat setting. Discovering the requirement after the wall is closed is the expensive version of this question.

Yes. The heater is independent of the flame on all three, so the firebox runs as a visual feature through summer and the heat is switched in when wanted.
