Building An Electric Fireplace Insert: A Step-By-Step Guide

how to build a electric fireplace insert

Electric fireplace inserts are a great way to add a cosy feel to your home, especially if you don't have a built-in fireplace. They can be a cost-effective alternative to a real fireplace, and you can even install a TV above it to complete the look. Before you begin, you'll need to decide on the size and height of your fireplace, and whether you want to include a mantel or surround. You'll also need to ensure you have an electrical outlet or hire an electrician to install one. When it comes to building your fireplace, you'll need to cut and attach 2x4s to create a platform for your insert, ensuring it fits snugly but can still be removed. You can then secure your insert with screws and attach the glass front. Finally, you can customise the look of your fireplace with paint, faux brick sheets, or decorative panels.

Choosing the right electric fireplace insert

Firstly, decide whether you want a log set or a firebox. If you're using an existing fireplace, measure the height, width, and depth of the opening. When purchasing, find an insert as close to these dimensions as possible. If you're building a new fireplace, decide how high you want the fireplace insert to be off the ground, and build a platform for your insert to sit on.

Electric fireboxes can be used to build new fireplaces. They can be framed into combustible walls and inserted into mantels or cabinetry without any special fireproofing or venting. Fireboxes have a traditional fireplace shape, but the flame display ranges from traditional to modern. You can choose to place logs or contemporary glass in front of the flames, and you can even change the flame brightness, colours, and other settings for a unique experience.

Electric fireplace inserts are designed to increase a fireplace's efficiency by up to 99%. They are energy-efficient, low-cost, low-maintenance, and safe. They are an excellent alternative to wood-burning fireplaces, which can absorb warm air out of the room and into the fire, and are often extremely inefficient. Electric inserts are also a good choice if you want to avoid the downsides of a traditional fireplace, such as complicated and expensive installation, air pollution, maintenance, or cleanup.

If you have a chimney, you will need to seal it off to eliminate heat loss. If you don't have an outlet where you want to build your fireplace, consider hiring an electrician to install one inside your fireplace framework.

Measuring the space and cutting materials

When building an electric fireplace insert, it is important to carefully measure the space where the fireplace will be installed and cut the materials accordingly. Here is a step-by-step guide to help you through the process:

First, determine the desired width and depth of your fireplace surround. For example, you may choose a width of 69 inches and a depth of 15 inches, ensuring it aligns with the studs in your wall for easier securing. It is important to consider the available space in your room and adjust the measurements as needed.

Next, decide on the height of your fireplace insert from the ground. A common choice is to set it at 10 inches off the ground. To achieve this, you will need to build a platform by cutting eight pieces of 2x4 lumber to 7 inches in length. Cut three additional pieces of 2x4 to the same length as your bottom front plate.

Now, it's time to assemble the platform. Screw four of the 7-inch pieces into your front plate, spreading them evenly across its length. Place one of the longer pieces on top of these four pieces and screw it down. Repeat this process for the back support, creating a mirror image of the front structure. Ensure that the front and back supports do not touch, as one will support the front of the insert, while the other supports the back.

After establishing the platform, cut four 2x4s to the desired height of your fireplace insert. For example, if the distance from the top of the insert to the portion sitting inside the fireplace is 25 1/2 inches, add 1/4 inch to this measurement to account for the warmth of the insert. This adjustment ensures that the wood isn't resting directly on the insert. Attach two of these cut pieces to the front inside of the left and right studs.

Finally, cut another 2x4 to the width between the studs and attach it to the top of the previously installed 25 3/4 inch pieces. Place the remaining two pieces of the same length on each side of the insert, allowing for a snug fit while leaving some wiggle room for airflow and future removal.

Remember, these measurements and steps may vary depending on your specific project and space constraints. Always measure twice and cut once to ensure accuracy and avoid mistakes.

Building a platform for the insert

Building a platform for an electric fireplace insert is a challenging but rewarding project. Here is a step-by-step guide to constructing a sturdy and stylish platform.

Planning and Materials

Firstly, decide on the desired height of your platform. In this example, 10 inches is chosen, but you can adjust this to your preference. You will need to purchase or source wood, fasteners, and finishing supplies. For wood, consider using pine, oak, or poplar for their strength and durability. You will also need wood screws, wood glue, and drywall screws. A Kreg Jig is a useful tool for creating pocket holes, and a brad nailer is perfect for trim work. Don't forget to wear protective gear like eyewear and gloves when using tools.

Cutting and Assembly

Cut 8 pieces of 2x4 to 7 inches in length. Cut 3 more pieces of 2x4 to the length of your bottom front plate. Screw 4 of the 7-inch pieces into your front plate, spreading them out evenly. Place one of the longer pieces on top and screw it down. Repeat this process for the back support, creating a mirror image of the front structure.

Platform Height and Insert Placement

Now you have a basic platform structure. Place your insert on the platform and ensure it is level and you are happy with the height. Measure from the top of the platform to the top of the insert, adding a little extra space to avoid the wood resting directly on the insert, which can get warm.

Final Assembly

Cut 4 2x4s to the measurement taken in the previous step. Attach one to the front inside of the left stud and one to the right, with the other two set aside. Cut another 2x4 to the width between the studs and attach it to the top of the previous two pieces. Now you have a secure platform for your electric fireplace insert.

Optional Steps

You can create studs for mounting a mantle or TV above your fireplace. Measure and cut 2x4s to the desired height and secure them. You can also add a shelf for TV components or any other decorative touches you desire.

Attaching the insert and securing it in place

First, determine how high you want the fireplace insert to be off the ground. This will depend on your personal preference and the overall design of your fireplace. In the example, the height chosen is 10 inches.

Next, build a platform at the desired height for the insert to sit on. Cut 8 pieces of 2x4 lumber to 7 inches long. Cut 3 additional pieces of 2x4 to the same length as your bottom front plate. Screw 4 of the 7-inch pieces into your front plate, spreading them out evenly. Then, place one of the longer pieces on top of these 4 pieces and screw it into place.

Repeat this process to create the back support. Place one longer piece on the floor between the two side walls, mimicking the front plate. Screw 4 of the 7-inch pieces into this longer piece. Finally, place another longer piece on top and screw it into the 4 shorter pieces. These two structures should not touch; one will support the front of the insert, while the other will support the back.

Now, it's time to attach the insert. Cut 4 2x4s to the appropriate length, allowing for some wiggle room for the insert. Attach one to the front inside of the left stud and one to the right stud. Cut another 2x4 to the width between the studs and attach it to the top of the previous pieces.

Place the insert inside the structure and secure it. You can use screws or other appropriate fasteners, depending on the insert's design. Make sure to follow the manufacturer's instructions for a secure and safe installation.

Once the insert is in place, you can make any necessary adjustments to ensure a snug fit while leaving some space for airflow and the removal of the insert.

Finally, you can reattach any trim or additional components, such as a glass front, to complete the look of your electric fireplace insert. Remember to follow the specific instructions provided with your electric fireplace insert for the best results and to ensure safety.

Customising the fireplace surround and mantel

Firstly, determine the size and proportions of your mantel and surround. The mantel should be wider than the fireplace by 3-6 inches on both sides to achieve a pleasing proportion. The surround can be made to the exact width of the mantel or extended further out to create a more substantial look. Keep in mind that the surround should be proportional to the size of your fireplace insert.

Next, choose the materials for your surround and mantel. MDF or oak are great options as they are easily painted and customisable. You can also consider tiling over an existing brick fireplace to create a fresh look. If you're using MDF, cut the sheets to size and attach them to the existing structure using adhesive and a nail gun. This will provide a smooth base for your surround.

Now, you can add built-ins or other decorative elements to your surround. Consider adding shelves or cabinets to the sides of your fireplace for storage or displaying items. You can also get creative and incorporate a TV mount above the fireplace, making it a functional entertainment centre.

Finally, don't forget to personalise your mantel with decorative items. This could include items like family photos, plants, candles, or seasonal decorations. You can also add hidden storage by building a drawer into the mantel, perfect for remotes and small items.

By following these steps and adding your own creative touches, you can design a fireplace surround and mantel that transforms your space and reflects your unique style.
