What is the cost to convert a gas fireplace opening to an electric insert in Calgary?

Converting a gas fireplace opening to an electric insert in Calgary typically costs $1,500–$4,500 all-in, depending on whether you keep the existing gas line capped, the size and quality of the electric insert you choose, and the finishing work required around the surround.

The electric insert itself is the biggest cost variable. A basic 36–42" electric insert with standard flame effects and a 1,500-watt (5,100 BTU) heater runs $600–$1,500 for the unit. Premium units with realistic multi-colour LED flames, remote control, adjustable ember beds, and higher-end cabinetry can reach $2,000–$3,000 for the unit alone. Installation labour — fitting the insert into the existing firebox opening, hardwiring it to a dedicated 120V or 240V circuit, and finishing the surround — adds $500–$1,500 depending on the electrical work required.

The electrical component is where most homeowners underestimate the cost. If your existing gas fireplace opening doesn't have a nearby dedicated circuit, you'll need a certified electrician to run one from your panel. That work requires an electrical permit from the City of Calgary and a Safety Codes Officer inspection before the circuit can be used. Budget $400–$800 for the electrical rough-in and permit if a new circuit is needed. A simple plug-in electric insert on an existing outlet avoids this cost entirely, but hardwired units look cleaner and are the better long-term choice.

On the gas side, you'll want a licensed gas fitter to properly cap and pressure-test the existing gas line — don't just leave it disconnected. This is a minor job ($150–$300) but it needs to be done correctly and documented. Some homeowners choose to leave the gas line intact and capped in case a future owner wants to convert back to gas, which is a reasonable approach.

What to Expect on Running Costs

This is where the Calgary math matters. Electric fireplaces running at 1,500 watts cost roughly $0.25–$0.35 per hour at current Alberta electricity rates. A gas fireplace running at 30,000 BTU costs approximately $0.50–$0.80 per hour at ATCO Gas rates — but delivers six times more heat output. For a primary heating source during Calgary's -25°C to -35°C cold snaps, an electric insert simply can't keep up the way a gas unit can. Electric inserts are best suited for zone heating a single room, ambiance, or condos and spaces where gas venting isn't practical.

Surround and Finishing Work

If the existing gas fireplace had a custom surround built around it, the electric insert may not fit the same opening dimensions. Many gas fireplaces have a smaller firebox opening than the surrounding mantel and tile work, so measure carefully before purchasing. If the surround needs modification or replacement, budget an additional $500–$2,000 for tile, drywall, and finishing labour.

The conversion itself is straightforward compared to a gas installation — no venting, no gas permit, no combustion air requirements. The main professional requirements are the electrical circuit work (certified electrician, electrical permit) and the gas line cap-off (licensed gas fitter). The insert fitting and surround finishing can often be handled by a general handyman or the fireplace installer.

If you're weighing whether conversion makes sense for your home, consider that a gas insert into your existing masonry or zero-clearance firebox would cost $3,000–$5,500 installed but deliver dramatically more heat output and lower operating costs over Calgary's six-month heating season. For a living room or primary gathering space, gas almost always pencils out better over time.
