Will a gas fireplace still work when the power goes out?
In Weaverville it often turns on the batteries. The brand-new fireplaces going into Reems Creek construction are electronic-ignition units that need power to light — most carry a battery backup, but only a live one keeps them working in an outage. Older downtown homes may run self-powered millivolt units that need nothing at all. Radiant heat stays; the blower doesn't.
New construction means electronic ignition
Weaverville's rapid growth around Reems Creek means a lot of the fireplaces we see are recent builder installs, and today's builder-grade gas fireplace is almost always electronic-ignition (IPI). It lights on a spark from wall power, then falls back to a battery pack — usually AA cells or a 9-volt behind the lower louver — when the grid drops. That's a genuinely good outage system, with one catch: it only works if the batteries are alive. A dead pack discovered during a storm is the most avoidable no-heat call we run, which is why we replace them at every annual service.
Older downtown homes, a different setup
The original masonry fireboxes in Weaverville's older downtown homes are a separate story — many are inefficient open hearths, and when we convert one to a sealed gas insert we can spec it millivolt so it needs no electricity whatsoever. That's the most bulletproof outage setup there is: the pilot makes its own current, and the unit heats through the longest grid-down stretch. Whichever you have, the blower stops without power, so you're getting radiant heat rather than fan-forced warm air.
Know which one you've got
The north-facing valley slows Weaverville's spring warm-up, so heating season lingers and it's worth knowing before winter exactly how your fireplace lights. We'll check your ignition, test or replace the battery pack, and pull the Buncombe County permit on any new line. If you're building in Reems Creek now, ask us to spec the ignition for outages before the wall closes up. Call (828) 545-0525.
