Electric fireplaces are one of my favorite “high impact, low drama” upgrades. You get flame ambiance, optional heat, and no venting. Most plug-in models are DIY-friendly. The trick is doing the boring parts right: support, clearance, and cord routing.
Below is a simple install guide for three common styles:
- Wall-hung units
- Freestanding fireplaces with mantels
- Fireplaces built into TV stands or cabinets
Before You Start: Quick Prep Checklist
Tools you’ll likely need
- Stud finder
- Level (24″ is ideal)
- Drill and bits
- Screwdriver
- Tape measure
- Painter’s tape and pencil
- Optional: cable raceway kit or in-wall power kit (code-approved)
Safety basics
- Use a dedicated outlet when possible.
- Don’t use a cheap extension cord.
- Keep the heater vents clear.
- Follow the clearance specs in the manual.
- Avoid mounting heat outlets under shelves that trap hot air.
Option 1: Install a Wall-Hung Plug-In Fireplace
Wall-mounted units look sleek and save floor space. Most hang like a heavy mirror.
Step-by-step
- Pick the height.
A common target is 12–24 inches above the floor. If a TV goes above, leave breathing room. - Find studs and mark the centerline.
Use painter’s tape for clean marks. Stud support matters more than perfect symmetry. - Confirm your outlet plan.
Ideally, the cord reaches a nearby outlet. If not, use a surface raceway to hide the cord. For a “floating” look, use a code-approved in-wall kit. - Install the mounting bracket.
Hold it level and mark the holes. Drill pilot holes into studs where possible. Use the included anchors only where allowed. - Hang the fireplace and lock it in.
Most units hook onto the bracket. Then you secure set screws underneath. - Test flame-only mode first.
Confirm lights, remote, and settings work. Then test heat on low for five minutes.
Pro tips
- Don’t guess your stud locations. Verify twice.
- Keep the bottom air intake unobstructed.
- Leave enough side clearance for service access.
Option 2: Install a Freestanding Fireplace With a Mantel
Mantel kits give a built-in look with simple assembly. Many are “furniture installs.”
Step-by-step
- Assemble the mantel shell.
Lay parts on a blanket to protect the finish. Tighten hardware, but don’t strip the screws. - Place the mantel where it will live.
Check that doors can open nearby. Also confirm the outlet is within cord reach. - Slide the firebox insert into the opening.
Most inserts screw into side brackets. Align it so the trim sits flush. - Secure the mantel to the wall if required.
Some kits include anti-tip brackets. Use them if you have kids or pets. - Plug in and test.
Run flame-only mode first. Then, run heat and confirm airflow.
Pro tips
- Mantels look best with a tight fit to the wall.
- Use felt pads under the base on hardwood.
- Don’t block the top vents with décor.
Option 3: Install a Fireplace Built Into a Cabinet or TV Stand
These are popular because they combine storage and a fireplace. Installation is usually the easiest.
Step-by-step
- Build the cabinet first.
Square the frame before tightening fully. A cabinet that’s out of square looks crooked. - Mount or place the unit safely.
Some are wall-hung, others sit on the floor. Follow the weight limits for each shelf. - Insert the fireplace unit.
Slide it in from the front or back. Secure it with the provided screws or brackets. - Plan the cord path.
Many cabinets have a cord cutout. Keep the cord away from heater vents. - Test and set your defaults.
Set brightness, flame color, and timer. Many people leave it on flame-only daily.
Pro tips
- Don’t put consoles or routers near hot exhaust.
- If a TV sits above, leave a gap and airflow space.
- Keep the heater intake free of pet hair.
Common Mistakes I See
- Mounting only into drywall with no stud support.
- Using an undersized extension cord.
- Pinching the power cord behind the unit.
- Covering vents with décor or curtains.
- Ignoring clearance rules near bedding or rugs.
Frequently Asked Questions
Do plug-in electric fireplaces need venting?
No, they don’t produce combustion fumes. They still need airflow for the heater fan.
Can I mount a TV above a wall fireplace?
Often yes, with proper spacing. Check the manual for clearance guidance. Use flame-only mode if you’re worried about heat.
Do I need a dedicated circuit?
It’s strongly recommended for heater use. A 1500W heater can draw around 12.5 amps. Avoid sharing that outlet with other heavy loads.
Can I hide the cord inside the wall?
Only with a code-approved power kit. Never run a standard cord inside a wall.
How long does installation take?
Most installs take 1–3 hours. Cabinet builds can take longer.

Conclusion
A plug-in electric fireplace is a solid DIY win. It adds instant atmosphere. It can also add real comfort heat. Pick the style that fits your room. Mount it safely, respect clearances, and manage the cord correctly. Once it’s in, you’ll wonder why you waited.
