The Complete Guide
Upgrading an existing fireplace doesn’t mean tearing out your current setup or installing an entirely new system. If you love the charm of your original fireplace but want the convenience, safety, and efficiency of modern technology, electric fire inserts are the perfect solution.
In this guide, we’ll walk you through everything you need to know about choosing and installing an electric fire insert in your existing fireplace—so you can enjoy the best of both worlds.
What Is an Electric Fire Insert?
An electric fire insert is a self-contained unit designed to fit into an existing fireplace opening. It replicates the look of a real fire using LED lighting and often includes features like glowing embers, realistic flame effects, and even crackling sounds. Some models come with built-in heaters, offering both visual ambience and supplemental warmth.
Benefits of Electric Fire Inserts
Easy to Install
Electric inserts are typically plug-and-play—just slide the unit into the fireplace opening and plug it into a standard outlet. No need for gas lines, flue upgrades, or structural work.
Realistic Flame Effects
Thanks to advancements in flame technology, many electric inserts now feature incredibly lifelike flame visuals, some even with adjustable colours, brightness, and speed settings.
Low Maintenance
No ash, soot, or chimney sweeping needed. Just switch it on and enjoy the ambience.
Optional Heat Output
Use the flame effect with or without heat, perfect for year-round use. Many models include a thermostatic heater with multiple settings.
Safe for Families
Since there’s no real flame or combustion, electric fire inserts are a safer choice for homes with children or pets.
Can I Install an Electric Insert in My Existing Fireplace?
In most cases, yes! Traditional open fireplaces—whether wood-burning or previously fitted with a gas fire—can usually accommodate an electric insert. Here’s what you’ll need to check:
Dimensions: Measure the height, width, and depth of your fireplace opening.
Power Source: You’ll need a nearby electrical outlet, ideally behind or next to the fireplace.
Ventilation: Not required. Electric fires don’t need a chimney or flue—just a solid, dry, and level surface to sit on.
Types of Electric Fire Inserts
Freestanding Electric Inserts
Designed to slot into your fireplace opening but not fixed in place. Great for flexibility and easy removal.
Built-In Electric Inserts
These are designed to be recessed into the fireplace for a cleaner, more permanent look. Installation may involve minor modifications for a flush finish.
Log Sets
If you want to keep the open look of your fireplace, opt for an electric log set. These sit in your fire grate and project realistic flames onto the back wall.
Style Considerations
Electric inserts come in a wide variety of styles to suit your home:
Traditional Designs: Classic brass or cast-iron effects, perfect for period homes or original fireplaces.
Modern Finishes: Sleek black or chrome trims, minimalist surrounds, and clean flame visuals for a contemporary update.
Stone & Marble Effects: Ideal for those wanting a more luxurious look.
Running Costs and Energy Efficiency
Electric fire inserts are generally energy efficient and cost-effective. Most models consume around 1.5–2 kW when the heat is on, and only a few pennies per hour when used for flame effects only.
Bonus tip: Many inserts come with timers, thermostats, and remote controls to help you manage energy use and comfort easily.
Whether you’re revamping an unused fireplace or simply looking for a cleaner, low-maintenance alternative, electric fire inserts offer a perfect blend of style, function, and convenience. They’re easy to install, safe to operate, and available in a range of designs to suit both modern and traditional interiors.
