Will my fireplace blower run during a power outage?
No — the blower on a gas fireplace runs on household electricity, so it stops when the power does, even on a unit whose flame lights without power. You'll still get radiant heat off the glass and firebox; you just lose the fan that pushes warm air out into the room. A battery backup keeps the ignition going, but not the blower — that needs a generator or power station.
Why the blower is the weak link
A fireplace blower is essentially an electric fan mounted behind or beneath the firebox, wired to a standard outlet. Its whole job is to move the heat the fire produces out into the room faster. That fan draws more power than the tiny igniter does, which is why battery-backup ignition systems — built to light the fire — don't run the blower. The flame and the fan are two separate questions: your unit may light with the grid down and still leave the fan dead.
You still get heat
Don't write off a fan-less fireplace in an outage. Radiant heat pours off the glass and the hot firebox regardless of whether the blower spins, and a gas fireplace or insert will warm the room it's in through natural convection — heat rises and circulates on its own, just more slowly. During Helene, plenty of mountain families held a living room at a comfortable temperature on radiant heat alone, no fan required. It's the difference between a warm room and a cold one.
If you want the fan in an outage
The only way to run the blower with the grid down is to power it — a portable generator or a battery power station sized for the fan's draw will do it, plugged into the same circuit the fireplace uses. That's a reasonable setup for folks who want maximum heat spread during long outages.
