Before purchasing an electric fireplace insert, ensuring the unit will fit perfectly within the existing fireplace is essential. Proper measurements will help prevent buying a unit that’s too large or too small for the space, ensuring a secure fit and optimal performance. This guide will walk through the steps needed to measure a fireplace for an insert accurately.
Tools Needed:
- Tape measure
- Notepad or digital device to record measurements
- Flashlight (if the fireplace is dark)
Key Measurements to Take
1. Measure the Fireplace Opening Width
The first measurement to take is the width of the fireplace opening. This is the distance between the two vertical sides of the fireplace at the front of the opening.
- How to Measure: Place the tape measure along the bottom front of the opening and measure from one side to the other. This is the maximum width the insert can be.
- Tip: For some fireplaces, the width may differ at the back of the opening compared to the front, so it’s also a good idea to measure the width at the back to ensure a snug fit.
2. Measure the Height of the Opening
Next, measure the height of the opening from the fireplace floor to the top of the opening.
- How to Measure: Position the tape at the bottom of the firebox (inside the fireplace) and measure up to the top of the opening. Make sure the tape is straight to get an accurate measurement.
- Tip: Check if the height is consistent across the front and back of the opening, as some fireplaces taper near the back.
3. Measure the Depth of the Fireplace
The depth measurement ensures the electric fireplace insert will fit entirely inside the firebox without protruding.
- How to Measure: Place the end of the tape measure against the back wall of the fireplace and pull it towards the front edge of the opening. This is the total depth.
- Tip: Check for any obstructions inside the firebox (like gas lines or uneven bricks) that could interfere with the installation. If any are present, factor these into your depth measurement.
4. Measure the Rear Width (if applicable)
Some fireplaces are not uniform in shape and may narrow at the back. This rear width is essential to measure if the fireplace has sloping sides or a tapered design.
- How to Measure: Measure the width at the back of the firebox where the rear wall meets the floor and compare this to the front width. This helps determine if a tapered insert may be needed.
5. Check the Surrounding Area
Take note of the clearance around the fireplace to ensure enough room for ventilation and any decorative trim or mantel. Some electric inserts come with surrounds or trim pieces, which may add to the unit’s overall size.
- Tip: Make sufficient space around the fireplace’s edges for these additional components.
6. Consider the Power Source
Lastly, determine the proximity of an electrical outlet. Most electric fireplace inserts plug into a standard 120-volt outlet, but make sure the cord can easily reach without creating a tripping hazard or needing excessive extension cords.
- Tip: If the outlet is farther away, consider using a power strip, but ensure it is rated for appliances like heaters.
How to Choose the Right-Sized Insert Based on Measurements
Once the measurements are taken, it’s time to choose an insert that fits the space. Remember that most electric inserts come in standard sizes, but there are also custom-sized options if your fireplace has unique dimensions. Here’s a quick guide:
- Width: The insert should be slightly smaller than the width of the fireplace opening to ensure it slides in comfortably. It’s generally recommended to leave 1/4 inch on each side for clearance.
- Height: Ensure that the height of the insert will not be taller than the opening. Most inserts are designed to fit comfortably inside standard fireplace openings but double-check the height to avoid cutting or modifying the structure.
- Depth: Ensure the depth of the firebox is sufficient to house the insert fully. Look for inserts designed for shallow or zero-clearance installations if the firebox is shallow.
- Adjustable Trim Kits: Many inserts come with adjustable trim kits that cover small gaps between the insert and the fireplace opening. This provides flexibility if the insert is slightly smaller than the fireplace dimensions.
Special Considerations for Oddly-Shaped Fireplaces
Measuring becomes more complex if the fireplace has a unique shape, such as an arched or tapered design. In such cases:
- Measure both the most comprehensive and narrowest points of the opening.
- Consider inserts that come with adjustable or flexible surrounds to fit non-standard shapes.
- You should consult a fireplace insert retailer for custom solutions if the measurements fall outside standard sizes.
Conclusion
Measuring for an electric fireplace insert is a simple process that ensures a perfect fit for your existing fireplace. By accurately measuring the width, height, depth, and any unique features of the firebox, it’s easy to find an insert that fits and enhances the room’s ambiance. Whether upgrading an old fireplace or adding warmth to a space, careful measurement is critical to a seamless and enjoyable installation.
FAQs
Can any electric fireplace insert fit inside an existing fireplace?
No, the insert must match the dimensions of the fireplace. Proper width, height, and depth measurements are essential to ensure a good fit.
What if the insert is slightly smaller than the fireplace opening?
Many inserts come with trim kits or surrounds that can cover small gaps between the insert and the fireplace opening, providing a clean and finished look.
How deep should a fireplace be for an electric insert?
The depth of the fireplace should match the depth of the insert. A minimum depth of 12-14 inches is ideal for most models, but shallower inserts are available for narrow spaces.
Do electric fireplace inserts need ventilation?
No, they do not require ventilation like gas or wood fireplaces. This makes them a low-maintenance option, suitable for a wide range of installations.
Can an electric fireplace insert be installed in a non-working fireplace?
Electric fireplace inserts can be easily installed in non-working fireplaces, transforming them into decorative and functional focal points without chimneys or vents.
