Warm up the mild Mississippi winters with a gas fireplace.

Expect somewhere between $3,500 and $8,500 for most projects in this area, with the spread driven mainly by whether you're setting a new propane tank versus tying into an existing line. A direct-vent gas insert dropped into an existing masonry fireplace, with propane already run to the house, sits toward the low end. A new built-in gas fireplace in a remodel—with framing, venting, and a fresh propane line and tank installed by a local supplier—lands toward the higher end. Since Rawls Springs runs mostly on propane rather than city gas, your propane supplier and hearth dealer will usually coordinate the tank sizing and line work together.

Almost certainly propane. Rawls Springs is unincorporated Forrest County, outside the municipal natural gas service that covers parts of Hattiesburg proper, so most homes here already heat, cook, or dry laundry on propane, and gas fireplaces follow the same pattern. Your local dealer will typically work with a regional propane supplier to size a tank (above-ground or buried) matched to your fireplace's BTU draw plus any other propane appliances in the house. If you do have an existing propane tank and line, that dramatically simplifies and lowers the installation cost.

Yes, and this matters more here than the mild winters suggest—southern Mississippi sees its share of ice storms and hurricane-related outages that can knock out power for days. Most gas fireplaces with intermittent pilot ignition (IPI) run on a battery backup that kicks in automatically when the power drops, so the unit lights and operates normally off stored AA batteries. Valor fireplaces take it a step further: the pilot's thermocouple generates its own electricity, so there's no battery to remember at all. Either way, ask your local dealer about the ignition system if reliable heat during storm season is a priority.

A gas fireplace is a fully built-in unit framed into a wall—the right choice for new construction or a remodel without an existing hearth. A gas insert drops into an existing masonry fireplace and uses that opening (with a new liner and cap) to deliver a sealed, efficient flame—a good fit for the older brick fireplaces common in this part of Forrest County. A gas stove is a freestanding cast-iron or steel unit that sits on a hearth pad, similar in footprint to a wood stove but running on propane. For most Rawls Springs homes with an existing masonry fireplace that rarely gets used, an insert is the simplest upgrade.

Forrest County does not enforce a countywide residential building code outside incorporated city limits, so a formal building permit often isn't required for a straightforward fireplace or insert swap in unincorporated areas like Rawls Springs. That said, the propane line and tank work still needs to be done by a licensed gas-fitter or your propane supplier's certified installer—that part isn't optional for safety and insurance reasons. If your project involves any structural changes (new framing, a new chase, or altering an exterior wall), your dealer can confirm whether Forrest County requires sign-off for that portion of the work.

Vented (direct-vent) units draw combustion air from outside and exhaust it back outside through a sealed pipe—they're the safer, code-compliant choice everywhere, including Mississippi. Vent-free units burn propane directly into the room with no external venting; they're legal here and popular for supplemental heat in smaller rooms, but they require careful room-sizing and an oxygen depletion sensor, and they add humidity to the air—a real consideration in Mississippi's already humid climate. Given how mild winters run in Rawls Springs, a vent-free unit can make sense for a den or sunroom that only needs occasional warmth, but a direct-vent fireplace is the better all-around pick for a main living space.

Plan on an annual inspection, ideally in early fall before the first cold front rolls through. A technician checks the burner, pilot assembly, propane connections, and venting, and cleans the glass and interior. Given how lightly most gas fireplaces get used in a 38°F-average-low climate like this one—often just a handful of weeks a year plus special occasions—annual service is usually enough to keep things running safely rather than a heavier seasonal schedule you'd see in colder states.

Because heating demand here is light—a short, mild winter season, compared to the long, deep-cold winters in a place like Fargo, ND—most homeowners don't need a high-output, whole-home gas heater. A mid-size direct-vent insert or fireplace in the 20,000–30,000 BTU range is plenty for zone heating a living room or den, with central HVAC or the existing ductwork handling the rest of the house. Save the larger, high-output units for homes that genuinely want the fireplace to carry primary heating load during a stretch of freezing nights—less common here than in colder parts of the country.

Electric fireplaces plug into a standard outlet, need no venting or propane line, and cost far less to install—often under $1,000—which makes them an easy option for a bedroom or secondary room where you just want the visual and a little supplemental warmth. At Mississippi Power Co. and Pearl River Valley Electric Power Association's residential rates (roughly 14–15 cents per kWh), running one occasionally costs pennies. A propane gas fireplace costs more upfront but delivers real, sustained heat and—with battery backup or a self-powered pilot—keeps working through the power outages that come with Mississippi's ice storms and hurricane season. For a primary living space, gas is usually worth the extra investment; for a secondary room, electric is hard to beat on simplicity.

If it was installed more than 15 years ago, probably. Older gas fireplaces keep a standing pilot light burning all the time, and that little flame can cost a couple hundred dollars a year. Newer models use pilot-on-demand ignition—the pilot lights only when you use the fireplace and goes out when you turn it off.

Open fireplaces suck—literally. As the fire burns, it consumes air your furnace already paid to heat and pulls it out through the chimney, so the house is actually colder after the fire goes out than before you lit it. An insert fixes this: it seals the chimney, puts fixed glass across the front, and turns that hole in your house into a real heat source.

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.

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.
