Add real warmth to a Lemay room—no chimney required.

Plug-in freestanding units and mantel packages typically run $300 to $1,200 installed, since they use an existing standard outlet and require no electrical work beyond setting the unit in place. Built-in wall units and inserts that need a dedicated 20-amp circuit run by a licensed electrician typically land between $1,200 and $2,500, depending on how far the panel is from the install location and whether drywall or trim work is needed to finish the opening. Most Lemay homes with an existing masonry fireplace fall in the middle of that range once an insert and surround kit are included.

Lemay is unincorporated, so building and electrical permits fall under St. Louis County's Department of Public Works. A plug-in unit that uses an existing outlet generally doesn't trigger a permit requirement. If your installer is running a new dedicated circuit for a built-in unit or insert—which is common for larger units—that electrical work needs to be pulled and inspected through the county. A licensed electrician handling the install will typically manage that paperwork as part of the job.

For zone heating, yes. Most electric fireplaces are rated around 1,500 watts and 4,600 to 5,000 BTU, which is enough to comfortably heat a 300 to 400 square foot room—a den, bonus room, or finished basement space—even with winter lows averaging 22°F outside. What it won't do is replace your furnace on the coldest nights of the year or heat an open-concept main floor by itself. Think of it as targeted supplemental heat that lets you turn the thermostat down elsewhere in the house rather than a whole-home heating solution.

If your home has an existing masonry fireplace that's sat unused because the chimney needs work or you've stopped burning wood, an electric insert is usually the best fit—it slides into that opening and puts the space back to use without touching the chimney. Wall-mount units work well in newer rooms or additions without an existing fireplace, since they hang like a piece of art and need only a nearby outlet or a short circuit run. Freestanding stove-style units are a good option for basements or bonus rooms where you want portability or a traditional look without built-in construction.

At Union Electric's residential rate of roughly $0.1256 per kWh, a typical 1,500-watt electric fireplace costs about 19 cents an hour to run at full heat output. Left running for a full evening—say 5 hours—that's under $1. Compare that to running a whole-house furnace to warm the same single room, and the savings add up quickly for anyone using a den or basement space regularly through a Lemay winter.

No—unlike a wood stove or a battery-backed gas unit, an electric fireplace needs grid power to run the heater and, on most models, the flame effect. If Union Electric service goes down after an ice storm or high wind event, the unit goes dark along with everything else in the house. If backup heat during outages is a priority for your household, that's worth discussing with a local dealer alongside your electric fireplace plans—some homeowners pair an electric unit for everyday convenience with a wood or gas appliance elsewhere in the house for outage coverage.

Look at heat output (most quality units top out around 4,600 to 5,000 BTU regardless of price), flame realism (higher-end models from brands like Dimplex and Napoleon use layered LED and mirror effects that look far more convincing than budget units), and whether you want heat-only, flame-only, or both running independently—useful if you want the look of a fire in mild weather without the extra warmth. A built-in thermostat with a remote is worth prioritizing for rooms you'll actually rely on for daily heat.

Gas fireplaces deliver more heat output and keep working during power outages if equipped with a battery-backed ignition system, but they require either a gas line run or an existing gas appliance hookup, plus proper venting—a bigger, more expensive project. Electric fireplaces install in a fraction of the time, need no venting or gas work, and cost far less upfront, but they're limited to supplemental zone heat and go dark in an outage. For a Lemay home already piped for gas with a fireplace opening ready to convert, gas is often worth the investment. For a room without gas service, a rental, or a straightforward heat-and-ambiance upgrade, electric is usually the faster, cheaper path.

In most cases, yes. Many of Lemay's older brick bungalows have a masonry firebox that's been sitting unused, and an electric insert is one of the simplest ways to bring that opening back into service. A local dealer will measure the firebox opening and depth to match an insert that fits without major masonry alterations—no chimney liner or damper work required, since the unit doesn't produce any combustion byproducts that need venting.

No—that's its superpower. An electric fireplace needs a wall and an outlet, period. No vent pipe, no gas line, no clearances to design around, which is why it works in bedrooms, offices, apartments, and walls where venting a gas or wood unit would be impractical or impossible. Installation is typically the simplest and least expensive of any fireplace type.

Yes—with an asterisk. Fireplaces are hot and TVs don't like heat. Either put a mantel between them to deflect rising warmth, or choose a fireplace with heat-management technology that creates a cool zone on the wall above—the wall stays around 125 degrees, barely warm, while the room still gets full heat. If you like clean lines and don't want a mantel, heat management is the answer.

Yes—by creating a comfort zone. A furnace heats every square foot of the house just to warm the one room you're in; a gas fireplace on low burns roughly a sixth of the gas a typical furnace does. Set the furnace around 55–60 degrees as a baseline, then heat the rooms your family actually uses. Families who heat this way commonly save $20–$60 a month.

For an average home—covering the fireplace, the vent pipe, and basic installation—a budget between $3,900 and $5,500 gives you a lot of options across wood, gas, and pellet. By the time you add finish work, gas line, and electrical, the average complete installation lands between $5,000 and $12,000 all-in. In a remodel or new build, a good rule is to put about 2.5% of the total project cost toward the fireplace.
