Which brands make electric fireplace inserts that retrofit into an existing fireplace?
For a true drop-in electric insert that slides into an existing masonry or prefab firebox, Dimplex is the brand we reach for — it makes the most convincing electric flame on the market. An electric insert needs only a nearby outlet, adds no venting or gas line, and turns a cold, unused fireplace into instant ambiance with light supplemental heat.
When an electric insert makes sense
You've got a masonry or factory-built fireplace you never light, you don't want to reline a chimney or run a gas line, and you mostly want the look with a little warmth. Drop in a Dimplex insert, plug it in, and you've got flame at the flip of a switch — no hauling wood, no cold-start smoke, no annual chimney sweep. It's the lowest-commitment way to bring a dead firebox back to life, and it's popular with renters and folks staging a home.
The honest limits
Electric is supplemental heat, not a furnace. A unit like this puts out around 5,000 BTU — roughly enough to take the chill off up to about 400 square feet — so it won't heat a drafty Asheville great room on its own. And here's the one we won't soften: electric is dead in a power outage. After Helene, the homes that stayed warm ran wood or gas. If backup heat is the goal, an electric insert is the wrong tool — a sealed gas insert with millivolt or battery-backup ignition gives you real, power-optional heat.
What we'd check first
The opening has to fit the insert, and the outlet needs to handle the load. We'll confirm both, and if your firebox is a good candidate for a gas insert instead — more heat, outage-proof — we'll tell you honestly rather than sell you the easy install.
