What is the price range for a double-sided gas fireplace in Calgary?

Double-sided gas fireplaces in Calgary typically cost $5,000-$12,000 installed, with the wide range reflecting unit quality, BTU output, venting complexity, and finishing materials. These see-through fireplaces are popular for open-concept homes where they can heat and provide ambiance to two rooms simultaneously.

Unit costs range from $2,500-$6,000 for the fireplace itself. Basic double-sided direct-vent models from manufacturers like Napoleon, Regency, or Majestic start around $2,500-$3,500 and produce 25,000-35,000 BTU. Premium linear double-sided units with contemporary styling and higher heat output can reach $5,000-$6,000. The key specification is BTU output — ensure the unit can adequately heat both spaces during Calgary's -30°C winter nights.

Installation complexity drives the higher costs compared to single-sided fireplaces. Double-sided units require careful framing to support the fireplace in the wall opening, gas line routing to the center of the installation, and venting that may need longer horizontal or vertical runs. Installation labor typically adds $1,500-$3,000 depending on gas line distance, venting route, and structural modifications needed.

Venting considerations are critical in Calgary's climate. Most double-sided gas fireplaces use direct-vent technology with coaxial vent pipe that can terminate horizontally through an exterior wall or vertically through the roof. Horizontal venting is usually less expensive but must account for Calgary's chinook winds and snow loading. The vent termination must be positioned to prevent downdrafts and maintain proper clearances from windows, doors, and property lines under the Alberta Building Code.

Finishing costs can significantly impact the total project budget. A basic drywall surround with simple tile or stone facing might add $1,000-$2,000. Custom stone surrounds extending floor-to-ceiling on both sides can easily add $3,000-$6,000. Popular Calgary finishes include stacked ledgestone, slate, and contemporary linear tile. Remember that double-sided installations require finishing materials for both room faces.

Permits and professional requirements include a gas permit from the City of Calgary (approximately $150-$200) and installation by a licensed gas fitter. The completed installation requires Safety Codes Officer inspection before operation. Given the structural modifications often needed for double-sided installations, a building permit may also be required.

Operating costs remain economical with ATCO Gas rates around $3.50-$5.00 per GJ. A 30,000 BTU double-sided fireplace costs roughly $0.75-$1.25 per hour to operate — excellent value for heating two rooms simultaneously during Calgary's six-month heating season.

Consider room sizing carefully — double-sided fireplaces work best in open-concept layouts where both spaces benefit from the heat output. In Calgary's climate, these units provide meaningful supplemental heating that reduces furnace load during extreme cold periods.
