The Biggest Fireplace Buying Mistakes (and How to Avoid Them)

Buying a fireplace should feel exciting—not stressful, confusing, or full of second-guessing. Yet many homeowners end up frustrated, over budget, or stuck with a unit that doesn’t suit their space simply because of a few avoidable mistakes.

Here are the most common fireplace buying mistakes we see—and exactly how to avoid them.

Mistake #1: Choosing a Fireplace Based on Looks Alone

A fireplace can look stunning online and still be completely wrong for your home.

What gets overlooked:

• Heat output (BTUs)

• Room size and ceiling height

• Mounting depth and wall construction

• Electrical or gas requirements

How to avoid it:
Start with function, then narrow down to style. Ask:

• Is this primarily for heat, ambiance, or both?

• Is the room open-concept or enclosed?

• Will this be a focal point or a background feature?

A good-looking fireplace that doesn’t heat properly—or overwhelms the room—quickly becomes a regret.

Mistake #2: Buying the Wrong Size Fireplace

Bigger is not always better.

Common sizing issues:

• Fireplaces that are too small to visually anchor the room

• Units that are too large and overpower the space

• Incorrect width for wall or framing constraints

How to avoid it:
Measure twice. Then measure again.

• Consider wall width, viewing height, and seating distance

• Linear fireplaces often look best when they span at least 60–70% of the wall feature

• Small rooms benefit from vertical or compact designs rather than ultra-wide units

When in doubt, mock it up with painter’s tape on the wall.

Mistake #3: Ignoring BTU Requirements

This is one of the most common (and costly) mistakes.

Problems we see:

• Fireplaces that barely warm the room

• Overpowered units that cycle on/off and feel uncomfortable

• Assuming all fireplaces heat “about the same”

How to avoid it:
Match BTUs to your space:

• Room square footage

• Insulation quality

• Ceiling height

• Climate zone

Electric fireplaces are excellent for zone heating and supplemental warmth. Gas fireplaces are better for whole-room or primary heating—but only when sized correctly.

Mistake #4: Not Thinking Through Installation Early Enough

Many buyers fall in love with a fireplace before checking if it can actually be installed.

Typical surprises:

• No nearby electrical outlet

• Insufficient wall depth

• Venting requirements not considered

• Clearance issues with TVs, mantels, or shelves

How to avoid it:
Before purchasing:

• Confirm power or gas availability

• Review framing depth and clearance specs

• Decide if the unit is wall-mounted, built-in, or insert-style

• Consult a licensed electrician or gas technician when needed

Installation constraints should guide your shortlist—not derail it later.

Mistake #5: Mounting the TV Too High (or Too Close)

The “TV over fireplace” setup is popular—but easy to mess up.

Common issues:

• Heat affecting electronics

• Uncomfortable viewing angles

• Ignoring manufacturer clearance requirements

How to avoid it:

• Choose fireplaces designed for TV installations

• Respect minimum clearance guidelines

• Consider mantel shelves or heat deflectors

• Balance screen height with seating distance

A well-planned setup looks intentional. A rushed one looks awkward—and feels worse.

Mistake #6: Overlooking Long-Term Costs and Maintenance

The sticker price isn’t the whole story.

Often forgotten:

• Installation labor

• Electrical or gas upgrades

• Venting components

• Maintenance and servicing

How to avoid it:
Ask for the total cost of ownership upfront.
Electric fireplaces generally have lower long-term costs. Gas units may cost more initially but deliver stronger heat output.

Clarity now beats surprises later.

Mistake #7: Buying From an Unauthorized Seller

This is a big one—and it causes real headaches.

Risks include:

• No manufacturer warranty

• No support if something arrives damaged

• MAP violations that void coverage

• Incomplete or outdated models

How to avoid it:
Buy only from authorized dealers who:

• Honor manufacturer warranties

• Follow MAP pricing

• Provide pre- and post-sale support

• Understand freight delivery and inspection procedures

If a deal looks too good to be true, it usually is.

Final Takeaway

The right fireplace should:

• Fit your space physically and visually

• Deliver the right amount of heat

• Install cleanly and safely

• Feel like a long-term upgrade—not a compromise

Avoiding these mistakes doesn’t require expert knowledge—just the right guidance before you buy.

If you’re unsure, ask questions early. A well-chosen fireplace pays you back every winter.
