Instant gas heat built for Powder River Basin cold.
With winter lows averaging 16°F and over 7,100 heating degree days a year, Gillette homes need heat that starts on demand. Find the right gas fireplace or insert and connect with a trusted local dealer.
Every Project Starts From One of These Five Situations
Steady heat when the wind doesn't quit.
Gillette sits at 4,532 feet on the open high plains of northeastern Wyoming, where wind-driven cold snaps push wind chill well below the average 16°F winter low. At roughly 7,150 heating degree days a year, the climate here runs closer to Bismarck, North Dakota than to the milder parts of the Mountain West—long heating seasons, dry air, and stretches where a fire needs to run for days without fail. Campbell County calls itself the Energy Capital of the Nation for good reason: this is Powder River Basin coal and natural gas country, and a lot of homeowners here appreciate the irony of driving past gas wells on the way to a propane delivery truck.
In-town Gillette properties are generally within reach of natural gas mains, while ranches and acreage properties out in Campbell County more often run on propane tanks. Either fuel works fine in a modern direct-vent fireplace or insert—your installer sets the unit up for whichever supply you have. Electric service is split between Powder River Energy Corporation for rural co-op members and the City of Gillette's municipal utility in town, which matters mainly for battery-backup ignition systems and blower-equipped units that need reliable house power. A gas fireplace also earns its keep during the smoky stretches of late summer, when wildfire haze off the Bighorns or the Black Hills makes wood burning less appealing—flip a switch and you get clean heat with nothing to feed.

Frequently Asked Questions
How much does a gas fireplace installation cost in Gillette?
Expect somewhere between $4,200 and $10,500 in Gillette, depending on the unit and the venting path. A direct-vent gas insert going into an existing masonry fireplace in one of the older homes near downtown, where a gas line is already run, sits toward the lower end. A new built-in gas fireplace for a remodel or new construction—with framing, direct venting through an exterior wall, and a fresh gas line—lands in the middle to upper range. Rural Campbell County properties that need a new propane tank set and a longer buried gas line run tend to land at the high end. A local dealer will walk your home and give you a firm number.
Can I convert my existing wood fireplace to gas?
Yes, and it's a common request from owners of older Gillette homes with a masonry fireplace that's more decorative than functional in a Powder River Basin winter. A gas insert typically slides into the existing firebox and vents through a stainless liner run up your current chimney, so you keep the look of the fireplace while gaining real heat output. Most conversions in Gillette run in the $4,500 to $9,000 range, with the swing depending on whether you're already on natural gas or need propane, and whether the flue needs relining.
Should I run natural gas or propane for my fireplace?
It depends on where in Campbell County you're located. Homes inside city limits are usually within reach of the natural gas main network, which is the simpler and generally cheaper option if you're already connected for a furnace or water heater. Outside town—on the ranches and acreage lots that make up much of the county—propane from a local supplier with a tank on the property is standard, and it's the norm for a lot of Gillette-area gas fireplace installs. Every direct-vent fireplace and insert we help match homeowners with can be configured for either fuel; your installer sets the correct orifice and regulator for whichever supply you're on.
Will my gas fireplace still work if the power goes out?
Most will, with a caveat worth knowing. Units with intermittent pilot ignition (IPI) run off a battery backup—typically a few AA batteries in the control compartment—that kicks in when utility power drops, so the fireplace still lights on demand. That matters in Gillette, where high-wind events on the open plains can knock out power for stretches at a time. Valor fireplaces take a different approach: their pilot assembly generates its own electricity through a thermocouple, so there are no batteries to remember or replace. Whichever brand you're considering, ask your local dealer how it handles a power outage before you buy.
What's the difference between a gas fireplace, gas insert, and gas stove?
A gas fireplace is a fully built-in unit framed into a wall—the right call for new construction or a full remodel. A gas insert drops into an existing masonry fireplace opening and uses your current chimney as the vent path, which suits a lot of the older housing stock around Gillette's original townsite. A gas stove is a freestanding cast-iron or steel unit that sits on the floor like a wood stove but burns gas—a good option for a shop, garage, or room without an existing chimney. Most Gillette homeowners upgrading an existing fireplace go with an insert; anyone building new or adding heat to a room without a flue usually looks at a built-in unit or a freestanding stove.
Do I need a permit to install a gas fireplace in Gillette?
Generally yes—a new gas fireplace or insert installation requires a building permit and gas line inspection through the City of Gillette Building Division for in-town properties, or the Campbell County Building Department for county properties outside city limits. The gas line connection itself needs to be run or verified by a licensed gas fitter. Most established hearth dealers in the area handle the permit paperwork and inspection scheduling as part of the installation, so you're not coordinating multiple trades yourself.
Vented or vent-free—which makes sense in Gillette?
Vented direct-vent fireplaces draw combustion air from outside and exhaust it back outside through sealed venting—they're the standard choice and the one most local dealers will steer you toward, since they deliver strong heat output without putting moisture or combustion byproducts into the house. Vent-free units are legal in Wyoming and can be a reasonable option for a room where running vent pipe isn't practical, provided you follow the room-sizing and ventilation rules that come with them. Given how dry Gillette's winter air already runs, most homeowners here prefer a vented unit—it doesn't add extra humidity to a house that's already fighting static electricity all winter.
How often does a gas fireplace need to be serviced?
Plan on an annual inspection, ideally before the heating season ramps up in the fall. A technician checks the burner, pilot assembly, venting, and gas connections, and cleans the glass and interior—a much lighter job than a wood chimney sweep, but just as important for a unit that's going to run through a long Gillette winter. Local service calls for this typically run $150 to $250. If you're on propane, it's also worth having your propane supplier check tank pressure and regulator condition at the same visit.
Gas or wood—which fits my Gillette home better?
Wood is still a solid option in Campbell County, especially with lodgepole pine, aspen, and ponderosa pine available from nearby national forest land in the Bighorns, and it keeps working even if the power's out. But wood burning gets complicated during the late-summer stretches when regional wildfire smoke settles over the plains and adding more smoke to the air isn't ideal—and hauling, splitting, and stacking cordwood through a high-wind Wyoming winter isn't for everyone. Gas offers instant, consistent heat with no smoke and no wood handling, which is why it's become the default choice for a lot of Gillette's newer housing. Plenty of local homes run both: gas for daily use in the main living space, wood as backup heat when it really counts.
What's the difference between an insert and a zero-clearance fireplace?
An insert is a fireplace that slides into a pre-existing wood-burning fireplace—if you don't have one, there's nothing to insert it into. A zero-clearance fireplace is built into a framed wall, which makes it the answer for remodels and new construction. Simple test: existing masonry fireplace means insert; blank or framed wall means zero-clearance.
Are new gas fireplaces really better than old ones?
Two ways, and they're both big. Looks: modern gas fireplaces are realistic enough that it's hard to believe they aren't burning wood. Cost: old units burn a standing pilot year-round (roughly $200 a year), while new ones use pilot-on-demand ignition and modern burners. Add remote controls and thermostat operation, and the day-to-day experience isn't close.
Does a fireplace add value to my home?
On average, a fireplace adds back to the home about the same amount you spent installing it. Add the monthly savings from heating the rooms you actually use instead of the whole house—often hundreds of dollars a year—and the value case is strong before you even count what a fire does for how your family uses the room.
What is an in-home preview and do I need one?
It's a visit where a hearth professional measures your space, confirms the model you picked actually works in your home, and walks the specs—framing, gas line, venting, finish work—before anything is ordered. Some details you just can't know until you see the house. Never make a down payment without one; it's the single most-skipped step that burns buyers.
