Quick Answer: Installing an electric fireplace takes anywhere from 5 minutes (freestanding, just plug it in) to a full weekend (recessed built-in with new wiring). Wall-mount units bolt to a bracket like a TV and need no venting since there’s no combustion. The step that actually determines your timeline and cost isn’t the fireplace itself — it’s whether your circuit can already handle roughly 12.5 amps of continuous draw, or whether you need a dedicated circuit added first, per manufacturer installation guidance from brands like Touchstone and Dimplex.
Unlike a gas insert, an electric fireplace never needs a flue, gas line, or combustion-safety inspection — every install question comes down to power and framing, not venting. Here’s the process for each of the three common install types, in order of difficulty.
Installation by type
| Type | DIY difficulty | Typical time | Electrician needed? |
|---|---|---|---|
| Freestanding / stove | Easiest | 5-10 minutes | No |
| TV stand / mantel package | Easy | 30-60 minutes | No |
| Wall-mounted (surface) | Moderate | 1-3 hours | Sometimes |
| Recessed built-in | Hardest | 1-2 days | Usually |
Full cost breakdowns for each type (unit price plus labor) are in our installation cost guide. Replacing an old wood or gas firebox instead of mounting new? Our insert installation walkthrough covers that specific process step by step.
Step 1: Confirm your power situation first
Before buying anything, check what circuit the fireplace will run on. Most plug-in electric fireplaces draw close to 1,500W, which is about 12.5 amps at a standard 120V outlet — already roughly 83% of a 15A breaker’s total capacity by itself. That’s why installation manuals for brands like Touchstone and Dimplex specify a dedicated circuit: sharing that breaker with a lamp, another appliance, or a second heater risks nuisance tripping at minimum, and is a safety issue at worst. If your intended spot doesn’t already have an outlet on its own circuit, budget for an electrician to add one — our cost guide puts a new dedicated circuit around $650-$700 on average, per HomeGuide’s 2026 data.
Step 2: Freestanding units — no installation, just placement
If you bought a stove-style or mantel-package unit, there’s no real “installation” step. Set it on a stable, level, non-flammable-adjacent surface, keep the manufacturer’s minimum clearance from walls and furniture (check the specific model’s manual — this varies by unit), and plug it into a grounded outlet. Done. This is the entire appeal of a freestanding electric fireplace for renters or anyone who wants zero commitment to a wall.
Step 3: Wall-mounted (surface) units
What surface wall-mounting actually involves
- Find studs. Most wall-mount fireplaces are heavy enough (30-60+ lbs) that they need to hang from studs or a stud-anchored bracket, not drywall anchors alone — use a stud finder and mark 16" on-center spacing, the standard US framing interval.
- Mount the bracket. Screw the included steel bracket directly into at least two studs, level it, then hang the unit onto the bracket exactly like mounting a flat-screen TV.
- Route the cord. Plan the outlet location before mounting — either an outlet already positioned behind or beside the unit, or a cord-management channel if you want a flush look.
- Confirm clearance. Most manufacturers require a minimum of 12" above the unit and 3-6" on each side for airflow, per typical installation manuals — check your specific model, since this varies.

Step 4: Recessed built-in units
This is the install type where a general contractor or electrician usually gets involved. The core steps: frame a rough opening to your exact model’s spec (measure twice — recess depth requirements range from 3.5” for many standard linear units up to 5.5-6” for larger units like some Dimplex IgniteXL configurations, per our sizing guide), run power into the cavity (this is almost always the electrician’s part, especially for a new dedicated circuit or if hardwiring a 240V unit for higher heat output), slide the unit into the framed opening and secure it per the manufacturer’s mounting hardware, then finish with trim, tile, or a mantel surround to close the gap between the fireplace and the wall opening.
FAQ-adjacent troubleshooting
If your fireplace is installed but not producing heat, that’s a different issue than installation — see our electric fireplace not heating troubleshooting guide. Missing a specific part mid-install, like a mounting bracket or trim kit? Our parts guide covers where to source replacements.
The bottom line
Power, not the fireplace itself, decides how hard your installation actually is. Freestanding and TV-stand units need nothing beyond an outlet. Surface wall-mount is a solid weekend DIY project once you’ve confirmed stud locations and clearance. Recessed built-ins are the one type worth budgeting an electrician for, mainly for the dedicated-circuit wiring rather than the mounting itself — get that part quoted before you buy the unit, not after.
