Transform your existing fireplace with a modern, efficient electric insert. Explore design possibilities, sizing tips, and features to create the perfect focal point for your home.
Why Choose an Electric Insert? An electric fireplace insert is one of the most versatile and cost-effective ways to upgrade an old, inefficient fireplace. It offers instant ambiance, supplemental heat, and a wide range of design options—all without the need for venting, gas lines, or chimney maintenance. Whether you're looking for a modern linear design or a traditional insert with a mantel, there's a style to match your home.
Popular Electric Insert Design Styles
Electric inserts come in a variety of design styles to complement any interior. From sleek and contemporary to rustic and traditional, your choice of insert can dramatically change the look and feel of your living space.
Modern & Linear
Clean lines, wide viewing areas, and minimalist frames. These inserts often feature realistic flame effects and can be installed flush with the wall for a seamless look. Perfect for contemporary homes.
- Wide, linear fireboxes
- Black or stainless steel frames
- Adjustable flame colors and brightness
- Crystal or glass ember beds
Traditional & Classic
These inserts mimic the look of a wood-burning fire with logs, glowing embers, and a more traditional frame. They often come with a mantel and surround to complete the look.
- Realistic log sets with ember glow
- Brick or stone interior panels
- Arched or rectangular frames
- Antique brass or black finishes
Rustic & Farmhouse
For a cozy, country-inspired aesthetic, consider inserts with a distressed wood or stone surround. These pair beautifully with DIY surrounds made from reclaimed wood or shiplap.
- Faux stone or brick panels
- Wood beam mantels
- Warm, amber flame settings
- Cast iron or dark metal accents
Sizing Your Electric Insert: A Critical Step
One of the most common mistakes when buying an electric insert is choosing the wrong size. An insert that is too small will look lost in a large opening, while one that is too large simply won't fit. Before you shop, you must measure your existing fireplace opening carefully.
How to Measure: Measure the width, height, and depth of your existing firebox at the front opening and at the back. Also note the size of any existing gas lines or vents. Most manufacturers provide a "framing" or "rough opening" dimension—this is the size your insert needs to fit into. For a deeper dive, see our guide on how to size a fireplace.
If you have a very small opening, you may need a 22-inch wide electric fireplace insert or a 18-inch model. For larger, grand fireplaces, a 60-inch ultra-thin insert can create a stunning focal point. You can also consider a best-fit insert for your existing fireplace to ensure a perfect match.
Installation & Design Considerations
Installing an electric insert is generally a straightforward DIY project, but there are a few design and safety factors to keep in mind.
Power & Venting
Electric inserts require a standard household outlet. They do not need venting, which means you can install them almost anywhere. However, you should ensure the outlet is accessible and not blocked by the insert. If you're replacing a wood-burning fireplace, you may be able to use the existing power or run a new line. Learn more about plug-and-play installation.
Surround & Mantel
The insert is just one part of the design. The surround and mantel complete the look. You can build a DIY surround for an electric fireplace using wood, tile, or stone. A popular option is an insert with a mantel that combines both elements in one package.
Heating Capacity
Many electric inserts are designed for ambiance, but some also provide supplemental heat. If you want an insert that actually warms the room, look for one with a heater. Models with a blower can circulate warmth more effectively. Check our guide on electric fireplaces that give off heat for more details.
Key Features for Your Electric Insert
Modern electric inserts are packed with features that enhance both aesthetics and functionality. Here are some of the most important ones to consider:
- Realistic Flame Effects: Look for inserts with realistic-looking flames and adjustable settings. Some models offer crackling sound effects for added authenticity.
- Remote Control: A remote control allows you to adjust heat, flame intensity, and timer from across the room. Many also offer universal remote options.
- Thermostat & Timer: Built-in thermostats help maintain a consistent temperature, while timers can automatically shut off the unit. See our fireplace thermostat guide for more.
- Flame Colors: Many inserts allow you to change the flame color to match your mood or decor, from traditional orange to modern blue and purple.
- Ember Bed Options: Choose from logs, crystals, or glass media to create your desired look. For a traditional feel, consider realistic electric fireplace logs.
Design Ideas by Room
An electric insert can be a stunning addition to any room. Here are some room-specific ideas:
Living Room
Make your insert the centerpiece of a fireplace wall with a TV above. Pair it with built-in cabinets around the fireplace for a custom look. A large electric fireplace with a mantel can anchor a spacious living room.
Bedroom
Create a cozy retreat with a small corner electric fireplace heater or a freestanding corner electric fireplace. For a sleek look, consider a thinnest wall-mount electric fireplace.
Dining or Kitchen
An insert can add warmth to a dining area or kitchen. A double-sided electric fireplace can be a unique room divider, offering views from both sides.
Maintenance & Troubleshooting
Electric inserts are relatively low-maintenance, but a little care will keep them looking and working their best. For general tips, see our electric fireplace maintenance guide and how to clean an electric fireplace.
If you encounter issues, common problems include not heating, flame not working, or remote control problems. Many issues can be resolved with a simple reset. For more, visit our fireplace troubleshooting section.
