Top 5 Mistakes People Make When Installing Electric Fireplaces

Electric fireplaces have become a popular choice for many homeowners looking to enhance their space with warmth and style. They come in a range of styles, from modern fireplaces with sleek lines to classic designs that suit any home. With an array of different colors and looks, these fireplaces can help create the perfect ambiance for any room.

While electric fireplaces are known for being easier and safer to install than traditional options, there are still important steps and details that need attention during setup. Knowing what to expect and how to avoid common mistakes can help anyone enjoy the comfort and visual appeal of their new electric fireplace for years to come.

5 Common Mistakes:

1. Failing to check if the home’s wiring can handle the fireplace’s power needs
2. Picking a unit that is too large or too small for the room
3. Ignoring how much space is needed around the fireplace
4. Installing it in a spot with poor airflow or unsafe surroundings
5. Expecting more heat than the unit was made to provide

1. Failing to Prepare for the Right Electrical Needs

Making sure an electric fireplace has the proper power supply is important for safe and reliable use. Some fireplaces can use a basic wall outlet, but built-in models usually need direct wiring into the home's electrical system. If the fireplace will be a main heater, it often needs a dedicated circuit, especially for those with a 1500-watt heater.

Common mistakes:

• Skipping a dedicated circuit, which can cause the breaker to trip
• Not finding out which side the wires must connect to
• Overlooking the need for 240V circuits for higher heat

When installing, always confirm the voltage and circuit needs before starting.

2. Picking the Incorrect Fireplace Size

Selecting the proper size for an electric fireplace insert is essential for safe and effective installation. Improper sizing can result in gaps, unsafe fits, or even the need to redo wall work. For those interested in a built-in model, it is important to measure the planned opening in the wall accurately. Always check the dimensions of the fireplace and make sure the wall is thick enough for the unit’s depth.

When installing an electric fireplace insert into an existing masonry fireplace, careful attention must be given to three main measurements:

• Width
• Height
• Depth

Comparing these measurements with the specifications of the chosen model helps ensure a snug fit. Many manufacturers provide detailed manuals or specification sheets, and it is wise to review these before buying. A well-fitted fireplace insert blends in with the space and works better, both for heat output and visual appeal. Mistakes in sizing can often be avoided by double-checking all measurements before any installation begins.

3. Failing to Allow Enough Space

Not leaving enough space around an electric fireplace can cause problems, especially when placing a TV above it. Even though electric fireplaces are cooler than traditional types, they still produce heat that might harm electronics.

Always check clearance recommendations:

• Look for minimum distances in the fireplace's manual.
• Common guidelines suggest leaving at least 8–10 inches between the top of the fireplace and the bottom of the TV.

Tip: Keeping the correct clearance helps protect both your TV and your fireplace.

4. Choosing an Unsuitable Spot for the Electric Fireplace

Selecting the right location for an electric fireplace is important for both safety and performance. Placing a built-in electric unit in a load-bearing wall without adjusting the wall’s structure can create serious issues. Professional guidance from a carpenter helps ensure the wall can safely support the fireplace and any necessary modifications are made.

Bathrooms are another area where placement can be a challenge. High levels of humidity in bathrooms can damage electric fireplaces not designed for moist environments. Before buying or installing, it's necessary to check if the fireplace is rated for bathroom use. Always review the manufacturer’s specifications and installation guidelines.

Key Considerations:

• Verify wall type before installation
• Seek expert help for structural changes
• Check product approvals for humid rooms

Proper placement can prevent costly repairs and help the fireplace last longer. Choosing the right spot also keeps your home safer and more comfortable.

5. Expecting Too Much from an Electric Fireplace’s Heating Ability

Many people think an electric fireplace can warm an entire house, but these units work best for small areas. A standard electric fireplace usually produces about 5000 BTUs, which is enough to heat a room of around 400 square feet. If the unit is wired to run at 240 volts, the heater might reach about 9000 BTUs, covering up to 900 square feet. This would be suitable for a single large room or a small cabin, but not for most whole homes.

Electric fireplaces are best for zone heating. They are most effective in rooms people use the most, which helps lower the main thermostat and saves on energy costs. It is important not to overestimate what these appliances can handle.
