Real Warmth, Zero Chimney Required.

Plug-in electric fireplace inserts and mantel packages typically run $300 to $1,200 installed, since most units just need a standard 120V outlet—no electrician required in many cases. Larger built-in wall units or linear electric fireplaces that need a dedicated circuit run $1,200 to $2,500, including the electrical work. Compare that to a wood or gas installation in this region, which routinely runs $4,500 or more once venting and chimney work are factored in—electric is by far the lowest-cost path to added heat in a Florissant home.

Most electric fireplace inserts include a built-in heater rated around 1,500 watts, which produces roughly 5,000 to 9,500 BTUs—enough to comfortably warm a single room of 300 to 400 square feet as supplemental heat. Running that heater at Ameren Missouri's residential rate of about 12.56 cents per kWh costs roughly 19 cents an hour, or about $4.50 for a full 24-hour day, though most Florissant homeowners run theirs a few hours in the evening rather than around the clock. It won't replace a furnace on a January cold snap, but it's an efficient way to heat the room you're actually sitting in instead of the whole house.

In most cases, no. A plug-in electric fireplace insert or freestanding unit that uses a standard outlet doesn't require any permit. If you're installing a larger built-in wall unit that needs a new dedicated circuit, that electrical work typically does require a permit through the City of Florissant Building Division (or the St. Louis County Department of Public Works if your address is in unincorporated county territory). A licensed electrician handling the circuit work will usually pull that permit as part of the job.

An electric insert is built to slide into an existing masonry fireplace opening, which makes it a natural fit for older Florissant homes with a fireplace that's rarely used—you get the look of a fire without dealing with the chimney. A wall-mounted or built-in linear unit is designed for new construction or a remodel, recessed into a wall or media console, and is popular in finished basements and additions where there's no fireplace opening to begin with. A freestanding electric stove mimics a wood stove's shape and can go almost anywhere with an outlet nearby—a good option for a sunroom or garage workspace. All three plug into standard household power in most cases.

No—and this is the honest tradeoff with electric heat. Because the unit runs entirely on household current, it shuts off the moment the power does, unlike a wood stove or a battery-backed gas fireplace. Ameren Missouri's service area sees occasional outages from summer storms and winter ice, so if backup heat during an outage is a priority for your household, a gas or propane unit with battery ignition is worth considering alongside or instead of electric. For everyday zone heating and ambiance, though, electric remains the simplest and cheapest option available.

Since Florissant's winters are moderate—average lows in the mid-20s rather than sub-zero—most homeowners here use electric fireplaces as supplemental zone heat rather than a primary heat source, and units in the 1,400 to 1,500-watt range cover that job well. Look for a model with a thermostat and multiple heat settings so you're not stuck choosing between off and full blast; that flexibility matters more here than raw BTU output, since you're typically supplementing a forced-air furnace rather than replacing one. A local dealer can help match wattage and flame style to the specific room you're heating.

Yes, and it's a common project in the city's older housing stock, particularly around Old Town Florissant and the mid-century neighborhoods off Charbonier Road. An electric insert slides into the existing masonry opening, and unlike a gas conversion, there's no need to run a gas line or install a liner—the old flue can simply be capped or left as-is. The whole job often costs under $1,500 including basic surround adjustments, which is a fraction of what a gas or wood-burning conversion would run once venting is factored in.

At Ameren Missouri's residential rate of roughly 12.56 cents per kWh, a 1,500-watt electric fireplace costs about 19 cents an hour to run. Natural gas, where available through the local utility, is generally cheaper per BTU delivered, but gas fireplaces cost considerably more to install upfront because of the venting and gas line work involved. For a homeowner heating one room a few hours a day, electric's low install cost usually wins out; for a household planning to run a fireplace as a daily primary heat source in the coldest stretch of winter, gas may pencil out cheaper over several years.

Florissant's housing stock leans heavily on postwar ranch and split-level construction, and a large share of these homes were never built with a masonry chimney at all—installing one after the fact is expensive and often impractical in a finished subdivision home. Local hardwood species like oak, hickory, and walnut are certainly available regionally, but between the lack of existing chimneys, county and municipal restrictions on new solid-fuel construction in some areas, and the convenience factor for a moderate-HDD climate like this one, wood heat has largely given way to gas and electric in Florissant. Electric in particular fills that gap well since it needs no chimney, no venting, and no gas line at all.

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.

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.

On average, a fireplace adds back to the home about the same amount you spent installing it. Add the monthly savings from heating the rooms you actually use instead of the whole house—often hundreds of dollars a year—and the value case is strong before you even count what a fire does for how your family uses the room.
