The Look of Fire, No Chimney Required, in Sunset Hills.

Unit cost for an electric fireplace ranges widely—roughly $300 for a simple mantel insert up to $2,500 for a large linear built-in with a realistic flame engine. Installation cost depends on the electrical work involved: a plug-in unit that uses an existing outlet has essentially no install cost beyond mounting, while a built-in unit drawing more than 1,500 watts usually needs a dedicated 20-amp circuit run by a licensed electrician, which typically adds $400 to $1,200 depending on how far the circuit has to travel from the panel. A local dealer can tell you which category your chosen unit falls into before you buy.

A plug-in electric fireplace that uses an existing wall outlet generally doesn't require a permit. If your project involves adding a new dedicated circuit or wiring a built-in wall unit, that electrical work falls under the City of Sunset Hills' building permit requirements, and it needs to be pulled by a licensed electrician. This is a much lighter permitting lift than a wood or gas installation—there's no venting inspection, no chimney clearance check, and no gas-fitter involved.

A built-in (or linear) electric fireplace is installed into a framed wall opening during a remodel or new construction, similar to how a gas fireplace would be framed in. An electric insert is sized to slide into an existing masonry fireplace opening, replacing an unused wood-burning firebox with a heat source that needs no chimney or venting at all. A plug-in unit—a mantel package, a stove-style freestanding model, or a wall-mounted unit—just needs a standard outlet and can be moved if you relocate. For Sunset Hills homes with an existing but rarely-used masonry fireplace, an insert is usually the most popular option.

Most electric fireplaces put out 5,000 to 9,000 BTU on a 1,500-watt heater setting—enough to noticeably warm a family room, bonus room, or finished basement, but not enough to replace a furnace on the coldest nights. Given Sunset Hills' relatively moderate winter lows (averaging around 25°F) and a winter heating season that's a little over half as demanding as a place like Madison, WI, a lot of homeowners here use electric fireplaces exactly this way: as targeted zone heat for the room they're actually sitting in, letting them turn the thermostat down elsewhere in the house.

Yes, and it's one of the more common projects local dealers see in Sunset Hills. Many homes here have an existing masonry firebox that rarely gets used for actual wood burning—an electric insert brings that fireplace back into daily use without cutting, stacking, or hauling firewood, and without needing to have an old chimney inspected or relined. The insert simply sets into the existing opening and plugs into a nearby outlet or a new dedicated circuit if the unit draws more power.

Gas fireplaces put out real heat—20,000 to 30,000 BTU is common—and with a battery-backed ignition system can keep running during a Missouri ice storm power outage, which electric units cannot do since they need grid power to run. Gas installations do require either an existing gas line (Spire serves natural gas in most of the St. Louis metro) or a new line run by a licensed gas-fitter. Electric skips all of that: no gas line, no venting, and a much smaller installation footprint, but it's supplemental heat only and goes dark in an outage. For a primary living room that needs real backup heat, gas often wins; for a basement, bedroom, condo, or secondary space where ambiance and easy installation matter more, electric is usually the simpler call.

At Union Electric's (Ameren Missouri) residential rate of about $0.1256 per kWh, a typical 1,500-watt electric fireplace running on its heat setting draws roughly 1.5 kWh per hour—about 19 cents an hour, or under $5 for an evening's use. Running the unit on flame-only mode with the heater off draws only a few watts, so most homeowners leave the ambiance running for hours without meaningfully affecting their bill.

Most electric fireplaces rated above 1,500 watts (the standard output for a full-size heater) need their own dedicated 20-amp circuit rather than sharing a circuit with other outlets and lighting. This is the main reason a built-in electric fireplace installation involves an electrician and a permit, while a smaller plug-in unit on an existing circuit typically doesn't. Your local dealer or electrician can confirm the wattage draw and whether your panel has room for the new circuit.

Flame realism varies a lot between brands—look at units from Dimplex, Napoleon, or Touchstone in person before buying, since photos rarely capture how convincing (or not) the flame effect looks. Beyond that, prioritize a built-in thermostat with a wall-mounted or remote control, a heater that can be run independently of the flame (so you get ambiance in summer without the heat), and multi-color or adjustable flame settings if you want more design flexibility. Since electric units in Sunset Hills are usually chosen for ambiance and supplemental warmth rather than as a primary heat source, the flame quality often matters as much as the wattage.

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.

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.

If you're putting a fire in your house on purpose, it's best to work with an expert. Unless you're genuinely experienced in framing, gas line, vent pipe, and the national code on clearances to combustibles, have a professional do it—and ideally the same company that sells you the fireplace, so warranty, service, and liability all live under one roof.

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.
