Electric Fireplaces & Inserts in St. Thomas, ON

The fireplace that plugs into any St. Thomas wall, no chimney required.

With winter lows averaging -8.5°C and most homes here already heated by Enbridge Gas or a hydro-fed furnace, an electric fireplace in St. Thomas is rarely the primary heat source. It's the fast, clean way to add warmth and glow to a basement, bedroom, or condo. I'll match you with a trusted local dealer who knows what actually fits your wall and your panel.

Why Electric Works Here

A supplement to the furnace, not a replacement for it.

St. Thomas sits in a milder pocket of southwestern Ontario, moderated by Lake Erie, so the winters here are real but nowhere near what a place like Sudbury or Thunder Bay deals with each year. Most homes run on Enbridge Gas for primary heat, and the dense hardwood supply across Elgin—sugar maple, red oak, white ash, yellow birch—keeps wood stoves and inserts common in older houses too. Electric fireplaces fit a different job entirely: instant ambiance and localized warmth in a finished basement, a nursery, or a condo unit where running a gas line or a Class A chimney isn't practical or allowed.

Depending on your street, your electricity comes from Hydro One, Alectra Utilities, or occasionally Toronto Hydro's broader network, with residential rates in the neighbourhood of 12.8 cents per kWh across the province. That keeps running costs modest for a unit used for a few hours an evening rather than around the clock. Installed costs for electric fireplaces in St. Thomas typically run $500 to $1,600—a fraction of a wood or gas project—since there's no venting, no gas line, and often no more than a standard 120-volt outlet or a straightforward hardwired circuit involved.

Frequently Asked Questions

How much does an electric fireplace cost to install in St. Thomas?

Most projects land between $500 and $1,600 CAD. A plug-in insert or mantel package that drops into an existing opening sits at the low end—you're basically buying the unit and setting it in place. A recessed wall unit that needs a dedicated circuit run by an electrician, common in basement finishing projects across Elgin region, pushes toward the top of that range once labour is added. Either way, it's well under what a wood or gas install runs here, since there's no chimney or gas line to account for.

Do I need a permit for an electric fireplace in St. Thomas?

A simple plug-in unit generally doesn't trigger a building permit. If you're having a wall unit hardwired on its own circuit, that electrical work should be done by a licensed electrician and may need to be inspected under Ontario's Electrical Safety Authority rules, and if the install is part of a larger basement or renovation project, the municipal building department in St. Thomas may want it included in that permit. It's a much lighter process than the CSA B365 code and WETT inspection that apply to wood-burning appliances in this region.

Is an electric fireplace enough heat for a St. Thomas winter?

Not as a sole heat source. With winter lows averaging -8.5°C and stretches colder than that, most electric fireplaces are rated to take the chill off a single room rather than replace the furnace tied to your Enbridge Gas service. They're a strong fit for zone heating—a finished basement, a home office, a bedroom that runs cold—while the furnace handles the whole house.

What's the difference between an electric insert, a wall unit, and a mantel package?

An electric insert is built to slide into an existing masonry firebox, which is a popular move for older St. Thomas homes with a wood fireplace that's gone unused—no chimney sweep, no WETT inspection, just a plug and a switch. A recessed wall unit sits flush in new framing, typical in a basement build-out. A mantel package is a freestanding cabinet with the firebox built in, which suits renters or condo owners who can't modify a wall at all. All three run off standard household current rather than a dedicated gas or wood venting system.

What will an electric fireplace add to my hydro bill?

At roughly 12.8 cents per kWh, a typical 1,500-watt electric fireplace costs around 19 cents an hour to run on full heat, less with the heater off and just the flame effect on. Run a few hours most evenings through the colder months and you're looking at a modest addition to your bill compared to what heating the same square footage with your furnace would cost. Whether you're on Hydro One or Alectra Utilities, the rate structure is similar enough that the math doesn't change much either way.

Which utility serves electric fireplaces in St. Thomas?

It depends on your exact address—Hydro One serves a large share of Elgin region, while some St. Thomas-area accounts fall under Alectra Utilities' territory. Check a recent bill to confirm which one bills you and at what rate; either way, current residential rates across Ontario sit close to the 12.8 cents per kWh average, so the fireplace itself isn't going to move the needle much regardless of provider.

Can I convert my old wood-burning fireplace to electric?

Yes, and it's one of the more common projects in St. Thomas's older neighbourhoods, where masonry fireplaces were built decades ago to burn local sugar maple or red oak and have since sat unused. An electric log insert drops into that same opening, needs no chimney sweep, no CSA B365 compliance, and no WETT inspection since it's no longer a solid-fuel appliance—which can actually simplify your home insurance conversation rather than complicate it.

Will my electric fireplace still work during a winter power outage?

No—unlike a wood stove burning sugar maple or white ash from the Elgin region, or even some battery-backed gas units, a standard electric fireplace goes dark the moment the power does. If outage resilience matters to you, especially given the ice storms that occasionally sweep through southwestern Ontario, it's worth pairing an electric fireplace for everyday ambiance with a wood or gas appliance elsewhere in the house as backup.

Electric vs. gas fireplace—which makes more sense for a St. Thomas home?

With Enbridge Gas already serving most of the city, a gas fireplace or insert (typically $6,000-$15,000 CAD installed) can genuinely supplement your heating on a cold night and keeps working with a battery-backed ignition system during an outage. An electric fireplace, at $500-$1,600, is the faster and far cheaper route when what you want is ambiance and zone warmth in a spot without a gas line—a condo, a rental, or a basement you're finishing on a tighter budget. Plenty of St. Thomas homeowners run gas as the main fireplace and add an electric unit in a second room.

How much does an electric fireplace cost to run?

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.

What fireplace styles should I know before shopping?

Four cover most of the market: screen-front traditional (mesh front, open feel, fits craftsman homes), traditional door set (the classic look you grew up with), modern linear (wide, low, the statement piece for entertaining), and clean face contemporary (no trim—your tile or stone runs right to the fire's edge). Walk in knowing those four terms and you're ahead of most buyers.

Do electric fireplaces actually produce heat?

Yes—most put out around 4,800–5,000 BTUs from a standard outlet, which comfortably warms a bedroom, office, or den as a comfort-zone heater. What they won't do is carry a whole house the way wood, gas, or pellet can. Think of electric as ambiance-first with honest supplemental heat: flames on with no heat in July, flames plus warmth in January.

Does an electric fireplace need a vent or chimney?

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.
