Measuring your existing wall opening is the first step before buying a Fireplace Insert Replacement Walls. Many homeowners struggle with dimension mismatches when trying to replace an old unit with a modern insert.

The Electactic 36-Inch Electric Fireplace is a linear indoor heating appliance built for either fully recessed in-wall installations or direct surface wall mounting. Measuring 36 inches wide, 18.11 inches high, and only 3.86 inches deep, it is well suited for homeowners and apartment residents who desire the ambiance of a fireplace without the venting, gas lines, or masonry work required by traditional hearths. Its minimalist black frame and low-profile design make it an attractive focal point below a television or along a main accent wall.
Heating capability is delivered via two selectable settings: a 750-watt low mode for gentle energy conservation and a 1,500-watt high mode producing 5,100 BTUs. The manufacturer specifies heating coverage for areas up to 400 square feet, making it an effective choice for zone heating in bedrooms, living rooms, and dens. For year-round visual enjoyment, the heating element can be turned off while keeping the flame effects active. Operating noise is rated at 45 decibels, and an integrated sleep mode pairs with a 1-to-8-hour timer to ensure controlled, quiet runtimes.
Visual customization is a standout feature of this model, powered by efficient LED lighting. Users can choose among 12 flame colors and 12 ember bed color combinations, alongside multiple levels of flame speed and brightness. Management of these features is straightforward via the front-facing touch screen or the included handheld remote control. Safety is supported by an onboard overheat protection system that shuts down the heating coil automatically if interior temperatures exceed operational limits.
From a setup standpoint, the 28.65-pound chassis and shallow profile facilitate straightforward installation, but planning is still necessary. For recessed applications, wall framing must accommodate the 3.86-inch depth, while surface-mounted setups require secure fastening to wall studs. Buyers should also verify access to a standard 120-volt grounded electrical circuit capable of supporting a 1,500-watt appliance, as running other high-draw devices on the same branch could lead to tripped breakers.
This electric fireplace serves as a reliable, cost-conscious heating and display solution for modern residential spaces. While it should not be expected to serve as a primary whole-house heat source, its customizable aesthetics, quiet operation, and flexible mounting options make it an appealing addition for anyone wanting clean, supplemental electric warmth.
The heating assembly in the Electactic 36-inch unit produces 5,100 BTUs on its 1,500-watt high setting, with a 750-watt low option available for mild temperature maintenance. The manufacturer rates this output to warm spaces up to 400 square feet, making it ideal for targeted zone heating where you want to warm an occupied room without adjusting the central thermostat.
Aesthetic controls operate independently from the heat blower, utilizing low-energy LED technology. Users can cycle through 12 flame color options and 12 ember bed hues, tailoring the ambiance to personal preference. Variable flame speed and brightness adjustments further allow the display to transition from a calm, low glow to an energetic linear visual.
This linear electric fireplace provides two distinct mounting configurations.

The outer dimensions are 36 inches in width, 18.11 inches in height, and 3.86 inches in depth, with a total unit weight of 28.65 pounds.
