Will my Ottawa home insurance rates increase or decrease after replacing an old wood fireplace with a gas insert?

Replacing an old wood fireplace with a gas insert will almost certainly lower your insurance premiums, and potentially by a meaningful amount. Insurance companies view gas inserts as dramatically safer and lower-risk than wood-burning fireplaces — they eliminate the creosote fire hazard, reduce structural stress on the chimney, and produce far fewer insurance claims.

The insurance savings come down to risk reduction. A traditional open masonry fireplace is an underwriter's concern in several ways: it operates at only 30 to 40 percent efficiency, which means most heat escapes up the chimney; it requires annual chimney cleaning and inspections to manage creosote buildup; and it has a meaningful fire risk if the chimney is neglected or damaged. A gas insert, by contrast, burns at 70 to 80 percent efficiency with minimal creosote production, has sealed combustion with direct venting (in most Ottawa installations), and produces far fewer insurance-related incidents. Insurers reward this lower risk with lower premiums.

How much will you save? In Ottawa, insurance premium reductions for converting a wood fireplace to a gas insert typically range from $100 to $300 annually, depending on your home's value, location, and your insurer's specific underwriting guidelines. Some insurance companies offer larger discounts — occasionally reaching $400 to $500 per year — while others are more modest. The discount usually applies as long as the conversion is documented and completed to code. The savings are genuine, but they are not so dramatic that they will fully offset the $2,500 to $5,500 cost of the insert installation. Still, over a decade, the insurance savings can amount to $1,000 to $3,000, which is meaningful.

What documentation matters for your insurer? After the gas insert is installed, you'll need written proof that the work was completed by a TSSA-licensed gas fitter and that the appliance received a compliance tag. You should also request a copy of the TSSA compliance certificate and any inspection documentation. When you notify your insurer of the upgrade, provide these documents — they will confirm the work was done to code and help your insurance agent process the premium adjustment quickly. Some insurers will also want a WETT Level 1 inspection of the chimney system to confirm it is in good condition, though this is less common for gas conversions than it is for wood stove installations.

One important caveat: If your old fireplace was not insured (some homeowners with deteriorated or unsafe fireplaces actually have them excluded from their insurance), then converting it to a gas insert may actually allow you to re-add fireplace coverage to your policy at a lower rate than if you replaced it with another wood fireplace. Conversely, if your fireplace was already insured at a reduced rate due to age or condition, the premium drop after conversion will reflect the difference between "aging wood fireplace" risk and "new gas insert" risk — so the absolute dollar savings may be smaller than the example ranges above, but the direction is always downward.

The broader financial picture: While insurance savings alone won't justify the conversion cost, they are a legitimate bonus on top of the other benefits gas inserts deliver in Ottawa's climate. You'll gain substantial heating efficiency, eliminate the hazard of creosote fires, reduce the need for frequent chimney maintenance, and enjoy the convenience of a fireplace that ignites with a remote or wall switch. For many Ottawa homeowners, especially those burning wood regularly during our long winter season, the combination of insurance savings, reduced maintenance costs, and improved heating efficiency makes the conversion financially sensible over a 10 to 15-year timeline.
