Are Electric Fireplaces Expensive to Run? The Honest Math

Most people flip the switch and hope for the best. Let's do better and actually run the numbers—because with an electric fireplace, the math is refreshingly simple. Power goes in, heat comes out, and your bill tells the whole story.

The good news: for most homes, that story has a happy ending.

What it actually costs

On its highest heat setting, an electric fireplace costs somewhere around a quarter an hour. Run it for a full evening—dinner, a movie, some reading—and you're looking at about a dollar. Do that most nights for a month and it adds roughly $30 to your electric bill.

Thirty dollars a month. That's the number that surprises people.

A few things move it: your local power rates, how long you run it, and the setting. In pricier areas (parts of New England and California), that monthly figure might land closer to $45–$55. In cheaper areas, less than $30. And if you run just the flame effect with the heat off—which most units let you do—you're paying pennies a night for pure ambiance.

How it compares

• Gas is often the cheapest fuel for serious heat, and a gas fireplace throws far more of it—enough to warm a big space or serve as real backup heat. It may cost a bit more per hour, but it's heating a lot more house.
• Wood can be the cheapest of all if you have access to affordable firewood—but you're also buying chimney cleanings and doing the work of hauling, splitting, and stacking.
• Electric sits in the middle. It's not the pick for heating a whole home cheaply—but for targeted, one-room warmth with zero installation fuss and basically no upkeep, the running cost is hard to argue with.

The savings you don't see on the meter

Two things make electric cheaper than the hourly number suggests.

First, zone heating. Turn the furnace down a few degrees and let the fireplace keep the room you're in warm. The furnace runs less, and the savings there can cancel out much—sometimes all—of that $30.

Second, the costs that simply don't exist. No annual gas service. No chimney sweep. No venting to maintain. No pilot light quietly burning fuel all winter. Over years of ownership, skipping those adds up to real money.

When it does get expensive

Two situations flip the math:

• Asking it to do too much. An electric fireplace comfortably warms a room of about 400–500 square feet—a normal living room or bedroom. Point it at a big, poorly insulated space and it'll run nonstop, never quite win, and cost you for the privilege.
• High local power rates. If your electricity runs well above average, that $30 can double, and a gas unit or wood stove starts to look better for regular heat.

So—expensive to run? For most people, clearly not. At around a quarter an hour, it's one of the cheapest ways to add real warmth and atmosphere to the room where you spend your evenings. Just use it for what it's built for: heating your room, not the whole house.
