Will a gas fireplace still work during an Ottawa power outage in the middle of winter?

A gas fireplace will continue to produce heat and flame during a winter power outage in Ottawa — but only if it is a standing pilot model, and even then with significant limitations. If your gas fireplace has electronic ignition that requires constant electricity, it will not light or operate without power, which is a critical vulnerability during Ottawa ice storms when extended outages are common.

Here is why this matters in Ottawa's climate: Winter power outages are not hypothetical risks — the 1998 ice storm knocked out power for weeks across the region, and major outages happen roughly every five to seven years. If your gas fireplace is your primary heat source or a crucial backup during an extended winter outage, losing the ability to light a fire could be dangerous. Conversely, a standing pilot gas fireplace is one of the few heating appliances that will keep working when the grid goes down, which is why some Ottawa families specifically choose them for this reason.

Standing pilot models work without electricity because the pilot flame is lit continuously by a small amount of gas flowing through a thermocouple (a heat-sensing device that generates a tiny electrical current without needing external power). When you turn on the fireplace, that small current opens the main gas valve. These fireplaces use manual controls — typically a wall knob or lever — with no electronic switches or ignition systems. A standing pilot model will heat your room and provide light during a power outage, though the heat output is usually more modest than a full-capacity fireplace burning at maximum BTU.

Electronic ignition models do not work without power. Most modern gas fireplaces use electronic ignition systems powered by wall outlets or hard-wired circuits. When the power goes out, the ignition system shuts down and the fireplace cannot light, even though there is still gas available. Some electronic models have battery backup systems that allow a brief window to light the pilot (typically 30 to 60 seconds of backup power), but once you turn off the fireplace or the batteries drain, you cannot relight it. After the power comes back on, the system resets and works normally.

Remote-controlled and smart gas fireplaces absolutely require electricity. Any fireplace with a remote, wall-mounted thermostat, or WiFi connectivity is electronically powered and will not operate during an outage. These models prioritize convenience and temperature precision over resilience, which is a reasonable tradeoff for most Ottawa homeowners — but it is important to know the limitation upfront.

If you are buying a gas fireplace with power outage reliability in mind, specifically request a standing pilot model and confirm that it can be operated with manual controls (knob or lever) during an outage. Ask the installer to demonstrate the manual lighting procedure before they leave. However, standing pilot models are becoming increasingly rare in new installations because they waste gas by burning the pilot flame continuously (even when the fireplace is off), and they lack the convenience and efficiency of modern electronic models.

A practical middle-ground strategy for Ottawa homeowners is to keep a wood stove or fireplace insert as a secondary heating source and install a standing pilot gas fireplace as a primary heat source or vice versa. A battery-powered backup generator (2,000 to 5,000 watts) can also keep an electronic gas fireplace running during a short outage, though it will not keep your whole house heated. If your gas fireplace is truly your only heat backup during a winter outage, a standing pilot model is worth the efficiency tradeoff — the cost difference between standing pilot and electronic ignition models is typically $500 to $1,500 installed, and that insurance against being without heat during a week-long ice storm has real value in Ottawa's climate.
