Is it cheaper to convert wood to gas or install a brand new gas fireplace in Calgary?

Converting an existing wood-burning fireplace to gas is typically $1,000-$3,000 cheaper than installing a brand new gas fireplace in Calgary, assuming your existing masonry chimney is in good structural condition and can accommodate a gas liner.

Wood-to-gas conversion costs range from $2,500-$5,500 in Calgary, which includes a gas insert unit ($1,500-$3,500), flexible aluminum or stainless steel liner installation ($800-$1,500), gas line connection by a licensed gas fitter ($400-$800), and the required gas permit and Safety Codes Officer inspection ($100-$200). You're essentially retrofitting your existing firebox and chimney rather than building from scratch.

New gas fireplace installation runs $4,000-$8,000 for a complete project, including the direct-vent unit ($2,000-$4,500), venting through an exterior wall or roof ($500-$1,200), gas line installation ($400-$800), framing and finishing work ($800-$1,500), and permits. The higher cost reflects the need to create a new fireplace location, run new venting, and complete all the finishing work around a brand new installation.

The conversion advantage disappears if your chimney needs major repair work. Before converting, you need a thorough chimney inspection to check for cracked liners, deteriorated mortar joints, damaged crowns, or structural issues. Calgary's extreme freeze-thaw cycles and chinook wind effects accelerate chimney deterioration, especially in homes built before 1980. If your chimney needs relining ($1,500-$3,500), crown repair ($500-$1,500), or extensive tuckpointing ($15-$30 per square foot), the total conversion cost can exceed new installation costs.

Efficiency considerations also matter for the long-term value. Your existing masonry fireplace operates at only 10-15% efficiency, losing most heat up the chimney. A gas insert conversion achieves 70-85% efficiency, while a new direct-vent gas fireplace reaches 75-85% efficiency. Both provide substantial heating improvement, but the new unit may have slightly better efficiency ratings and longer warranty coverage.

ATCO Gas availability makes both options cost-effective to operate in Calgary, with running costs of roughly $0.50-$1.00 per hour at current natural gas rates. The conversion route makes sense when you love the existing fireplace location and your chimney passes inspection. New installation gives you complete flexibility in placement and the latest efficiency technology.

Both projects require gas permits and Safety Codes Officer inspection — never attempt DIY gas line work. A licensed gas fitter must handle all gas connections, and the completed installation needs approval before operation.
