Real Heat, Real Ambiance—No Chimney Required.

A basic plug-in electric insert or wall-mounted unit typically runs $150 to $800 for the unit itself, and if it plugs into an existing standard outlet, there's no installation cost beyond mounting hardware. Built-in units with a custom mantel surround, or larger models that require a dedicated 240V circuit, push the total project to $1,500–$3,000 once an electrician is involved. Because Greendale's original 1938–41 housing stock often has older wiring and smaller panels, it's worth having a local electrician confirm panel capacity before committing to a larger built-in.

Most electric fireplaces are rated around 5,000 to 10,000 BTU (roughly 1,500 watts on the heat setting), which is enough to noticeably warm a 300–400 square foot room with the door closed, but it isn't sized to carry a whole house through a long Milwaukee County winter. Think of it as targeted zone heat for a den, finished basement, or bedroom addition—most Greendale homeowners run their electric unit alongside the furnace rather than instead of it, and use it on its own in the shoulder seasons when the furnace would otherwise cycle on for one chilly room.

A standard plug-in unit that uses an existing 120V outlet needs no permit at all. If you're installing a built-in model that requires a new circuit or panel work, that electrical work needs to be pulled by a licensed electrician and typically gets inspected through the Village of Greendale Building Inspection Department. Because Greendale has a historic district covering much of the original Greenbelt-era housing, any exterior changes tied to the project—like altering a mantel surround on a home with historic designation—may also need a quick check with the Village before work starts.

An electric insert is sized to slide into an existing fireplace opening, which works well if your Greendale home has one of the original decorative fireplaces from the 1938–41 build-out that was never hooked up to gas or used for wood. A built-in unit is framed into a wall from scratch, usually with a custom mantel, and is the choice for additions or basement remodels with no existing fireplace. A wall-mounted linear unit hangs like a piece of art with a slim profile and no surrounding cabinetry—popular in condos and smaller rooms where floor space is tight. All three plug into standard or dedicated circuits and need no venting.

At We Energies' residential rate of about $0.1923 per kWh, a typical 1,500-watt unit running on the heat setting costs roughly $0.29 per hour, or a little under $3 for a full evening. Running the flame effect alone without heat draws far less—often under 100 watts—so you can leave the ambiance on for pennies an hour even in the shoulder seasons when you don't need the extra warmth.

Many of the Cape Cods and Colonials built during Greendale's original 1938–41 development have a small existing fireplace opening that was never wired for gas or used regularly for wood. An electric insert sized to that opening is usually the cleanest fit—it uses the existing mantel and surround and needs no structural work. For additions, finished attics, or basements without any fireplace at all, a slim wall-mounted linear unit is the more practical option since it doesn't require framing a new hearth wall.

We Energies supplies both electric and natural gas service throughout Greendale, so most homes have the option either way. Gas delivers real, substantial heat output and can be sized to genuinely supplement the furnace on a cold January night, but it requires a gas line, venting, and a few thousand dollars more in installation. Electric skips all of that—no gas line, no venting, install cost often under $1,000—but its heat output is modest and best treated as zone heat rather than a serious backup source. For a room that just needs ambiance and light supplemental warmth, electric is usually the simpler and cheaper answer. For a room you want to genuinely rely on when it's below zero outside, gas is the better investment.

Very little, which is a big part of the appeal. There's no chimney to sweep and no annual gas technician visit required—just an occasional wipe-down of the glass front and a check that any air filter or vent on a fan-forced unit isn't clogged with dust. Most LED flame effects are rated for 20,000+ hours of use, so you're unlikely to replace bulbs for a decade or more of normal use. It's one of the lowest-upkeep heating appliances you can put in a Greendale home.

No—electric fireplaces need grid power to run the heater fan and flame effect, so they'll go dark the moment the power does, unlike a wood stove or a gas fireplace with battery-backup ignition. Milwaukee County sees its share of winter ice storms and summer outages, so if backup heat during an outage is a priority for your household, an electric fireplace should be considered ambiance and supplemental warmth only—pair it with a generator, a gas unit, or another non-electric heat source if outages are a real concern for your home.

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.

With the heater on, a typical unit draws about 1,500 watts—at average electric rates that's roughly 20 cents an hour. Run the flame effect alone and it costs pennies; the flames are LED-driven and use about as much power as a light bulb. There's no pilot light, no fuel delivery, and essentially no maintenance.

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.

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.
