Electric Fireplace Inserts for Wood Burning Fireplace

If you have an old wood burning fireplace that sits unused because of the mess, maintenance, and safety concerns, an electric fireplace insert for wood burning fireplace is a practical and modern solution. This guide will walk you through everything you need to know — from how these inserts work to sizing, installation, and what to look for when buying. By the end, you'll have the confidence to make the right choice for your home.

Unlike traditional wood burning, electric inserts require no chimney, no venting, and no fuel storage. They plug into a standard outlet and deliver consistent, thermostat-controlled heat with realistic flame effects. It's a transformation that can modernize your living space and potentially add value to your home.

Why Choose an Electric Insert for Your Wood Burning Fireplace?

Converting an existing wood burning fireplace to electric is one of the simplest and most cost-effective ways to upgrade your hearth. Here are the primary benefits:

• No venting or chimney required: Electric inserts do not produce smoke or carbon monoxide, so you don't need a chimney or flue. This is especially useful if your existing chimney is damaged or needs expensive repairs. For more details, see our guide on whether fireplaces need a chimney.
• Clean and low-maintenance: There's no ash, soot, or creosote to deal with. You'll never need to schedule a chimney sweep or worry about creosote buildup.
• Safe operation: Electric inserts produce no carbon monoxide, making them a safer alternative for indoor use. You can learn more about electric fireplaces and CO production here.
• Easy installation: Most electric inserts are designed to fit into an existing fireplace opening and simply plug into a standard household outlet. In many cases, you can install an electric fireplace into an existing fireplace yourself with basic tools.
• Energy efficiency: Electric inserts convert nearly all the energy they consume into heat, making them highly efficient for zone heating. They are often considered among the most energy-efficient fireplace types.
• Year-round ambiance: You can enjoy the flame effect with or without heat, making it a versatile decorative feature even in summer. If you're wondering whether electric fireplaces look tacky, our article on whether electric fireplaces are tacky can help.

How Does an Electric Fireplace Insert Work?

An electric fireplace insert is a self-contained unit that fits inside the opening of your existing wood burning fireplace. It typically consists of:

• Heating element: Most models use either infrared quartz or fan-forced heating elements to generate warmth.
• Flame effect: LED lights and rotating mirrors or ribbon effects create the illusion of a realistic fire. Some high-end models even include crackling sound effects and multi-color flames.
• Thermostat and controls: Most inserts come with remote controls, built-in thermostats, and timers. You can also find models compatible with smart Wi-Fi controllers.
• Blower: Many units include a blower fan to distribute heat more effectively throughout the room. If you're unfamiliar with blowers, read our guide on fireplace blower fans.

Because the unit is electric, it doesn't require a flue to exhaust byproducts. However, if your fireplace damper is open, you may lose some heat up the chimney. Using a fireplace draft stopper can help prevent heat loss when the insert is not in use.

Types of Electric Fireplace Inserts

Not all electric inserts are created equal. Understanding the different types will help you choose the one that best fits your needs and your existing fireplace.

1. Standard Electric Inserts

These are the most common and versatile options. They are designed to fit into a standard fireplace opening and typically offer 1,500 watts of heating power, which is enough to heat a room up to 400 square feet. Many standard models include a remote control, adjustable thermostat, and multiple flame brightness settings. These are generally entry-level to mid-range in terms of features.

For a deeper look at how these stack up against other options, see our comparison of electric fireplace inserts for existing fireplaces.

2. Infrared Electric Inserts

Infrared inserts use quartz tubes to produce heat that feels warmer and is distributed more evenly than traditional fan-forced heaters. They are often more energy-efficient and can be a better choice for larger rooms or for people who want a more comfortable, consistent warmth. These are typically mid-range to premium in terms of features.

Infrared heating is known for its quiet operation and ability to heat objects rather than just the air. This can make a room feel warmer more quickly, especially in drafty spaces.

3. Built-In or Recessed Electric Inserts

These are designed to be flush with your wall or fireplace surround for a seamless, modern look. They are ideal if you're planning a renovation or want a clean, built-in appearance. Built-in models often require more precise measurements and may need a professional for installation. They are typically mid-range to premium in terms of features.

If you're considering a built-in unit, our article on built-in vs freestanding fireplaces can help you weigh the pros and cons.

4. Electric Insert with Mantel

Some electric inserts come as part of a complete package that includes a mantel and surround. These are great if you want a turnkey solution that transforms the entire look of your fireplace wall. They are available in a range of styles, from traditional to modern, and are typically mid-range to premium in terms of features.

Sizing and Fit: Will an Electric Insert Work in Your Fireplace?

Before you buy, you need to measure your existing fireplace opening carefully. Electric inserts are designed to fit standard sizes, but you'll need to account for the width, height, and depth of your firebox.

• Width: Measure the opening at the front and the back. The insert needs to fit inside the opening with some clearance for ventilation.
• Height: Measure from the hearth to the top of the opening.
• Depth: Measure from the front to the back of the firebox. Most electric inserts are relatively shallow, but you'll want to ensure there's enough room for the unit and any required clearance.

Most electric inserts are designed to fit standard fireplace openings, but if your fireplace is unusually large or small, you may need a custom solution. For more on sizing, see our guide on how to size a fireplace.

If you're looking for an insert for a smaller space, consider a fireplace for small spaces.

Heating Capacity and Efficiency

Electric inserts are rated by their heating capacity, usually measured in British Thermal Units (BTUs) or watts. Most residential electric inserts produce around 5,000 BTUs, which is sufficient to heat a room up to 400 square feet. Some larger models can produce up to 10,000 BTUs and heat up to 1,000 square feet.

To determine what size you need, consider the square footage of the room and how well it's insulated. A general rule of thumb is 20 BTUs per square foot of living space. For a more precise calculation, see our guide on heating capacity and BTU guide.

In terms of efficiency, electric inserts are nearly 100% efficient at converting electricity into heat. However, the cost of electricity varies by region, so it's worth understanding the electricity usage and daily running cost before you commit. If you're concerned about running costs, our article on whether electric fireplaces are expensive to run provides a detailed breakdown.

Installation: What to Expect

One of the biggest advantages of electric inserts is their ease of installation. Unlike gas or wood inserts, there's no need for venting, gas lines, or complex permitting in most cases. Here's a general overview:

1. Measure your fireplace opening: Ensure the insert will fit.
2. Clean the firebox: Remove any debris, ash, or old logs.
3. Prepare the space: If necessary, cap the chimney or install a draft stopper to prevent heat loss.
4. Place the insert: Slide the unit into the opening and secure it if required.
5. Plug it in: Most units plug into a standard 120V outlet. If you don't have an outlet nearby, you may need an electrician to install one.
6. Enjoy: Turn it on and adjust the flame and heat settings to your preference.

In many cases, you can complete the installation yourself in under an hour. However, if you're not comfortable working with electrical components or if your fireplace requires modifications, it's best to hire a professional. For more information, see our guide on DIY vs professional fireplace installation.
