Real gas heat for Fremont County's long, cold winters.

Most gas fireplace installations in Fremont County run somewhere between $4,500 and $10,500, depending on the unit, the venting path, and whether new gas line or propane tank work is needed. A direct-vent insert going into an existing masonry fireplace with gas already run to that wall sits on the lower end. A full built-in unit for new construction or a remodel—with framing, venting, and a fresh gas or propane line—lands in the middle to upper end. Homes in more remote parts of the county, like Dubois or Jeffrey City, sometimes see a modest travel charge added by installers covering that distance. A local dealer will give you a firm number after an in-home look at your space and existing fuel line.

Yes, and it's a common project for older homes in Lander and Riverton with masonry fireplaces built decades ago for wood. A gas insert typically drops into the existing firebox and uses your existing chimney as the venting path with a stainless liner, running $4,500 to $9,000 depending on the insert and whether propane or natural gas is involved. Homes already on natural gas in town tend to land on the lower end; homes needing a new propane line or tank sit higher. The conversion keeps the look of your original fireplace while removing the wood-splitting and ash cleanup that comes with heating through a Fremont County winter the old way.

Propane works fine and is the standard fuel for most of Fremont County outside the immediate Riverton and Lander town limits. If your home already runs on propane for a furnace or water heater, adding a gas fireplace on the same tank is straightforward. In the areas where natural gas service reaches—mostly in and around the larger towns—homeowners with gas already run to the house usually find it's the simpler and cheaper path. Nearly every gas fireplace, insert, or stove on the market can be set up for either fuel; your installer just configures the correct orifice and regulator for what you have.

Most will, which matters in a county where winter storms and high-wind events can knock out power for hours at a time. Units with intermittent pilot ignition (IPI) run on a battery backup—typically AA batteries built into the unit—that kicks in automatically and lets the fireplace light on demand with no wall power. Valor units go a step further: their pilot assembly generates its own electricity through the thermocouple, so there are no batteries to remember at all. For a Fremont County home relying on a gas fireplace as backup heat during an outage, that distinction is worth asking a local dealer about directly.

A gas fireplace is a fully built-in unit framed into a wall—the right call for new construction or a remodel where there's no existing masonry opening. A gas insert is built to slide into an existing wood-burning fireplace, sealing it up and using the chimney as the vent path, which is common in older Lander and Riverton homes. A gas stove is freestanding, sitting on the floor like a wood stove but running on gas or propane—a good fit for a room with no fireplace at all, including many ranch homes and cabins scattered around the county. Which one makes sense depends mostly on what opening, if any, you're starting with.

Yes—new gas fireplace installations typically require both a building permit and gas line work signed off by a licensed gas-fitter, coordinated through the local building department covering your part of Fremont County (Riverton, Lander, and unincorporated areas each have their own review process). Most established hearth dealers handle this paperwork as part of the installation, coordinating the gas line, venting, and inspection together rather than leaving multiple trades for the homeowner to schedule separately. If you're on propane, your supplier will also need to sign off on the tank and line setup before the fireplace is connected.

Vented gas fireplaces—direct-vent or B-vent—pull combustion air from outside and exhaust the byproducts back outside through sealed venting. Vent-free units burn fuel directly into the room with no outside venting at all, which is more efficient on paper but releases water vapor and small amounts of combustion byproducts into the living space, and comes with strict room-sizing and ventilation rules. Vent-free units are legal in Wyoming but less common; for a Fremont County home dealing with a winter heating load in the same range as Bismarck, North Dakota, most local dealers steer homeowners toward direct-vent units, which deliver more usable heat and don't require any compromise on indoor air quality.

Plan on an annual inspection, ideally before the heating season ramps up in the fall. A technician checks the burner, pilot assembly, venting, gas connections, and any electronic ignition components, and cleans the glass and interior. It's a shorter visit than a wood-stove chimney sweep but just as important for safety and for keeping the unit running efficiently through a long Fremont County winter. Expect to pay somewhere in the $150-$250 range for a standard annual service call from a local gas appliance technician.

Wood—typically lodgepole pine, aspen, or ponderosa pine cut locally—offers strong heat output, lower fuel cost if you're cutting your own, and the ability to run with no electricity at all, which matters during winter outages on ranches and in outlying communities. Gas offers instant on-off convenience, no ash or creosote to manage, and steadier output without tending a fire. Fremont County's wildfire smoke concerns in late summer and fall also push some homeowners toward gas for cleaner year-round operation, even if they keep a wood stove for backup. Plenty of homes here run both—gas in the main living space for daily use, wood in a shop, cabin, or secondary space for backup heat.

An insert does two things: it seals the chimney completely, so you stop losing air you already paid to heat, and it radiates warmth into the room through the firebox and glass. Most add a heat-exchange fan that pulls cool room air underneath, wraps it around the hot firebox, and pushes it back out warm. Your home is more efficient before you've even lit the first fire.

Yes—modern gas fireplaces have a battery backup for the ignition system that lasts for weeks, so no power equals no problem. Your furnace can't say that: no electricity, no blower, no heat. It's one of the most common reasons families add a fireplace, and worth confirming on any model you're considering.

For an average home—covering the fireplace, the vent pipe, and basic installation—a budget between $3,900 and $5,500 gives you a lot of options across wood, gas, and pellet. By the time you add finish work, gas line, and electrical, the average complete installation lands between $5,000 and $12,000 all-in. In a remodel or new build, a good rule is to put about 2.5% of the total project cost toward the fireplace.

If you're putting a fire in your house on purpose, it's best to work with an expert. Unless you're genuinely experienced in framing, gas line, vent pipe, and the national code on clearances to combustibles, have a professional do it—and ideally the same company that sells you the fireplace, so warranty, service, and liability all live under one roof.
