What's the total cost difference between a wood-burning insert and a gas insert installed in Ottawa?

The installed cost difference between a wood-burning insert and a gas insert in Ottawa is roughly $500 to $1,500, with wood inserts typically running slightly higher, though the gap is narrower than many homeowners expect.

A gas insert in Ottawa costs $2,500 to $5,500 installed, while a wood-burning insert runs $3,500 to $7,000 installed. At first glance, this suggests wood is consistently more expensive, but the real picture is more nuanced because both prices include the insert unit itself, installation labour, chimney modifications, and hearth pad work. The overlap in these ranges means that a mid-range wood insert might actually cost less than a premium gas insert, depending on the specific models chosen and your chimney's condition.

What matters more than the upfront cost difference is the total cost of ownership over time. A gas insert requires a gas line installation if one doesn't already exist near your fireplace — add $500 to $1,500 for that run. Gas inserts also need annual service inspections by a licensed technician at roughly $150 to $250 per year. A wood insert requires annual chimney cleaning and sweeping by a WETT-certified sweep at $175 to $350 per year, plus you'll need to purchase firewood at $350 to $450 per cord in Ottawa. If you burn 3 to 4 cords per season (typical for supplemental heating), that's an additional $1,050 to $1,800 in fuel costs annually.

The gas insert wins on convenience and operating cost — you pay nothing for fuel, simply flip a switch or press a remote, and the heat comes instantly without the mess of ash or the commitment to seasoning and stacking firewood. Gas inserts also produce significantly less creosote buildup because they burn cleaner, so your chimney cleaning intervals might stretch longer. However, a wood insert gives you the authentic experience of a real wood fire, provides substantial heat output (often 60,000 to 80,000 BTU), and creates a deeper sense of ritual and comfort that many Ottawa homeowners genuinely value on long winter nights.

One critical consideration: if you're converting from an open masonry fireplace, both insert types require chimney relining with a properly sized stainless steel or aluminum liner. A gas insert typically uses a smaller liner (5-inch or 6-inch), while a wood insert usually needs a larger liner (6-inch or 8-inch). If your existing chimney liner is deteriorated — common in Ottawa's freeze-thaw climate — you may face unexpected chimney relining costs of $2,000 to $5,000, which can dwarf the difference between insert types. Always get a chimney inspection before pricing an insert project; a WETT Level 1 inspection costs $250 to $450 and will reveal whether relining is necessary.

Insurance is another hidden cost factor. Most Ottawa insurance companies require a WETT inspection before insuring a wood-burning insert, and some charge slightly higher premiums for wood-burning appliances due to fire risk. Gas inserts don't typically trigger premium increases, though insurers want documentation that installation was performed by a TSSA-licensed gas fitter.

If you're leaning toward a wood insert, the real payoff comes from the warmth of burning wood and the heating contribution to your home during Ottawa's long winters — the economics work best if you value that experience and have space to properly season and store firewood. If convenience, lower operating costs, and instant heat are your priorities, a gas insert is the more practical choice and will likely cost you less over a decade of ownership.
