A wall mounted electric fireplace changes a room without requiring a chimney, gas line, or major renovation. You mount it to the wall, connect it to a power outlet, and you have a working fireplace the same day. But "wall-mounted" covers a wide range of installation types, from true surface mounts that hang like a picture frame to fully recessed units that sit flush inside a drywall cutout. Choosing the wrong configuration for your wall structure is the most common mistake buyers make, and it usually becomes clear only after the unit arrives.
This guide covers what you need to know before ordering a wall mounted electric fireplace: how installation types differ, what specs to prioritize, and which models are worth considering at different price points.
Most electric fireplaces marketed as "wall-mounted" fall into one of three installation categories. Understanding which one you need shapes every other buying decision.
Surface mount units attach directly to the wall face with mounting hardware. No recess is required. The unit protrudes from the wall, typically 5 to 7 inches, which works well where no wall cutout is available. The SimpliFire Format 36" is a purpose-built surface mount that ships with a separately purchased floating mantel kit, creating a finished built-in look without any drywall work. This is the fastest and most renter-friendly installation type.
Recessed (built-in) units sit inside a wall cavity. Most require between 4 and 12 inches of wall depth depending on the model. A standard 2x4 framed wall offers roughly 3.5 inches of usable depth, which is not enough for most recessed fireplaces without additional framing or a chase build-out. A 2x6 wall provides around 5.5 inches. Anything requiring more depth needs custom framing built in front of the existing wall structure.
Dual-mode units are designed to work both ways: surface-mounted on the wall or recessed to varying depths for a more integrated look. The Modern Flames Spectrum Slimline and Modern Flames Orion Slim both support slide-in built-in or direct wall-mount installation, so the same unit works whether your wall has a cutout or not.

Available wall depth is the first constraint to verify, not the last. Measure from the wall surface to any wiring, insulation, or structural elements behind the drywall. If your wall has less than 4 inches of clearance, a surface-mount model is the correct starting point. Ordering a recessed model without confirming depth compatibility is the single most expensive mistake in this category.
Width relative to your wall affects how the unit reads in the room. A useful starting point: the fireplace face should span 50 to 80 percent of the wall it occupies. On a 12-foot wall, that puts you in the 72 to 96-inch range. Going too narrow on a wide wall makes the fireplace look like an afterthought rather than a focal point.
Electrical requirements vary by model. Most residential wall-mounted electric fireplaces run on a standard 120V/15A or 20A circuit and are plug-in ready. Some larger or dual-zone models require a 240V hardwired connection, which adds installation cost and requires a licensed electrician. Always confirm the electrical specification in the product listing before ordering.
Heat output is consistent across most residential electric fireplaces. The standard heater rating is 5,000 BTU (approximately 1,500 watts), which covers roughly 400 to 450 square feet. Heat is an optional feature on all electric fireplaces, so these units work equally well in spaces where you would not want added heat by simply running the flame effect without the heater engaged.
Controls and connectivity range from basic remote-and-manual to full Wi-Fi integration with app control and voice assistant support. The Modern Flames Orion Slim includes Wi-Fi connectivity, Alexa and Google Home support, and a physical remote. The Spectrum Slimline uses remote and manual controls only. If smart home integration matters to you, confirm that the model supports it before choosing.
Worth Considering for Bedrooms: Modern Flames Spectrum Slimline
Media wall setups are the most common application. The fireplace sits below the TV, either recessed into a custom entertainment surround or surface-mounted with a floating mantel. Models in the 50 to 60-inch range tend to balance visually under a 65-inch or larger TV. For wider media walls, the 74" and 100" sizes available in the Spectrum Slimline and Orion Slim families provide a proportionally correct look.
Bedrooms benefit from a narrower footprint and quieter operation at lower flame settings. The SimpliFire Format at $779 is built for this kind of placement: surface-mount, no recess needed, and paired with an optional floating mantel for a finished appearance. In a bedroom where wall depth is limited or the installation budget is modest, it covers the use case well.
Open-plan living rooms generally need 72 inches or wider to register as a focal point against a full wall. The Modern Flames Orion Slim is available up to 100 inches and includes a 15-inch viewing window height that carries well across large open spaces. Three customizable flame pattern styles and multi-color ember and downlighting give more ambient control in rooms where the fireplace is the primary focal point.
Apartments and rentals with limited wall access call for a true surface mount. No drywall cutting means no permanent modification, which matters in rental situations or where the wall finish must stay intact. The SimpliFire Format ships with all hardware needed for wall mounting and is available in stock for immediate shipment.
The following models cover the main tiers of the wall-mounted electric fireplace collection, from entry-level surface mounts to Wi-Fi-integrated premium units.
SimpliFire Format 36" ($779) is the most accessible option. Surface-mount with no wall cutout required, plug-in power on a standard 120V outlet, and up to 400 square feet of heat coverage. A separate floating mantel kit creates a built-in appearance. One-year warranty. In stock.
Modern Flames Spectrum Slimline (starting at $1,599) is a mid-range option available in 50", 60", 74", and 100" sizes. It supports both slide-in built-in and direct wall-mount installation, delivers 450 square feet of heat coverage, and includes a hand-painted Canyon Driftwood log set with independently controlled flame, ember bed, and downlighting in 10 color options. Controlled by remote and manual panel.
Litedeer Homes Latitude II (starting at $2,499, reduced from $2,899) is a smart wall-mount electric fireplace available in 48", 58", 68", and 78" widths. It connects via mobile app in addition to remote and manual controls, covers up to 400 square feet, and includes a 3-inch trim kit for a clean recessed finish. In stock.
Modern Flames Orion Slim (starting at $4,279) is the premium option in the category. Available in 52", 60", 76", and 100" sizes with a 5,000 BTU heater, Wi-Fi control via the Modern Flames app, Alexa and Google Home integration, and three customizable flame pattern styles in six colors. The viewing window is 15 inches high. Supports both wall-mount and recessed installation.
A Fan Favorite for Media Walls: Modern Flames Orion Slim
Ordering before measuring wall depth. The most expensive mistake in this category. Built-in capable models require a minimum wall cavity depth to recess properly. If your wall cannot accommodate the depth, you need a surface mount or a framing build-out. Measure before ordering, not after.
Choosing based on width alone. Two models can share the same face width but differ significantly in recess depth, viewing window height, and feature set. The Spectrum Slimline and Orion Slim both come in 100-inch sizes but represent very different price points, flame technologies, and control options. Width is one input, not the only one.
Assuming all models are plug-in ready. Most residential electric fireplaces in this collection run on 120V and are plug-in compatible. Confirm the electrical specification in the product listing before purchasing, especially for models above 60 inches where 240V requirements become more common.
Skipping the trim or mantel kit. Many recessed fireplaces require a separately purchased trim kit or mantel to achieve a flush-finished look. The SimpliFire Format requires a floating mantel purchased separately. The Litedeer Latitude II includes a 3-inch trim kit. Factor these into the total cost when comparing options.
For a broader look at built-in configurations, the built-in electric fireplace collection includes additional models that support recessed or semi-recessed wall installations.
Not all of them. Surface-mount models like the SimpliFire Format attach directly to the wall face with no cutout needed. Recessed or built-in models require a wall cavity, typically 4 to 12 inches deep. Models that support both methods, like the Spectrum Slimline and Orion Slim, can be installed either way depending on your wall construction.
Standard 2x4 framed walls provide roughly 3.5 inches of cavity depth. Most recessed models require at least 4 to 5 inches. If your wall depth is insufficient, you can build a chase or custom framing in front of the existing wall to create the necessary depth, or choose a surface-mount model instead.
The recommended configuration is below the TV, not above it. Heat from the fireplace rises, which causes discomfort when seated and can put sustained heat stress on electronics mounted directly above. Below-TV placement also reads better visually and allows heat to distribute across the room naturally.
Most residential models in this range run on 120V and plug into a standard wall outlet. Some larger models or those with dual heating zones require a 240V hardwired connection. Always confirm the electrical specification in the product listing before ordering.
A useful starting point is that the fireplace face should span 50 to 80 percent of the wall width where it will be installed. For a 10-foot wall, that puts you in the 60 to 96-inch range. For media wall applications, the fireplace should be proportional to or slightly narrower than the TV it sits below.
Electric fireplaces convert electricity to heat with 100 percent efficiency, since no heat is lost through venting. The 1,500-watt (5,000 BTU) heaters common in these models cost roughly 15 to 20 cents per hour to run at full heat output, depending on your local electricity rate. Running the flame effect only, without the heater engaged, draws significantly less power.
