Gas heat that works when St. Louis County winters turn sharp.
Wellston sits low and close-built along the inner ring of St. Louis County, where winter lows average 25°F and older homes rely on zone heat to take the edge off. Find the right gas fireplace or insert and get matched with a trusted local dealer.
Every Project Starts From One of These Five Situations
A compact city built for efficient, low-maintenance heat.
At just under 2,000 residents and barely half a square mile, Wellston is one of the smallest incorporated cities in St. Louis County—a dense grid of early-to-mid-20th-century bungalows and duplexes built long before central air was standard. Climate zone 4A here means real winter, with a solidly cold, months-long heating season and lows that regularly dip into the mid-20s, but nothing close to the sustained sub-zero stretches you'd see in a place like Fargo or Duluth. That makes gas an especially good fit: enough cold to justify a dedicated heat source, not so much that you need a wood-burning workhorse running around the clock.
Wood heat is uncommon here for practical reasons—narrow lots, shared walls, and tight setbacks make cutting, stacking, and burning cordwood impractical for most Wellston households, even though oak, hickory, walnut, and maple are the common regional species just outside the city. Natural gas infrastructure, by contrast, runs through most of this part of St. Louis County via Spire, the regional utility that inherited much of the old Laclede Gas system, which means many of Wellston's older masonry fireplaces are strong candidates for a direct-vent gas insert. For homes without a gas line nearby, electric fireplaces through Union Electric (Ameren Missouri) at roughly 12.6 cents per kWh are a straightforward, low-cost backup option.

Frequently Asked Questions
How much does a gas fireplace installation cost in Wellston?
Expect a typical gas fireplace or insert installation in Wellston to run somewhere between $3,800 and $9,500, depending mostly on whether you're converting an existing masonry fireplace or building out a new one. Many of Wellston's bungalows and duplexes from the 1920s through 1940s already have a working chimney, which keeps costs down since the insert can vent through the existing flue with a stainless liner. Homes needing a new gas line run from the street, or a fireplace built into a wall with no existing chimney, land toward the higher end. A local dealer will give you a firm number after seeing the space in person.
Can I convert my old wood fireplace to gas?
Yes, and it's one of the more common upgrades in this part of St. Louis County, where older housing stock still has the original wood-burning masonry fireplace intact but rarely gets used for actual wood fires anymore. A gas insert slides into the existing firebox, uses a stainless steel liner run up your current chimney, and connects to a gas line—typically a one- to two-day job. It preserves the look of the original brick surround while giving you instant, thermostat-controlled heat instead of a fireplace that mostly sits cold and unused.
Is natural gas available in Wellston, or do I need propane?
Most of Wellston is served by natural gas through Spire, so if your home already has gas service for a furnace, water heater, or range, adding a fireplace is usually a matter of tapping into the existing line rather than starting from scratch. Propane is rarely necessary inside city limits here—it tends to come into play only for detached structures or outbuildings without an existing gas connection. Either fuel works in most modern fireplace models; your installer sets the unit up for whichever you have.
Will a gas fireplace still work if the power goes out?
Most direct-vent gas fireplaces with intermittent pilot ignition (IPI) include a battery backup that keeps the unit operable during a power outage—the igniter and blower can run off AA batteries when the grid drops. Valor units go a step further: their pilot assembly generates its own electricity through the thermocouple, so there's no battery to remember or replace. For Wellston homes on Ameren's grid, where ice storms and summer line work can occasionally knock out power for stretches, that self-powered ignition is worth asking about when comparing models.
What's the difference between a gas fireplace, insert, and stove?
A gas insert is built to slide into an existing masonry firebox—the most common option for Wellston's older homes with a fireplace already in place. A gas fireplace is a fully framed, built-in unit used in new construction or when you're adding a fireplace where none existed. A gas stove is a freestanding cabinet-style unit that sits on the floor and vents through a wall or ceiling, useful in smaller rooms or additions where there's no chimney to work with at all. For most homeowners here with an existing brick fireplace, the insert is the simplest and least invasive path.
Do I need a permit to install a gas fireplace in Wellston?
Yes. Gas fireplace installations require both a building permit and gas line work performed or inspected by a licensed gas-fitter. Because Wellston is a small city, permitting and inspections for this kind of work are typically coordinated through St. Louis County's Building Division rather than a standalone city department. A reputable local hearth dealer will already know this process and will pull the permits and schedule inspections as part of the installation, so it's not something you need to manage yourself.
Should I get a vented or vent-free gas fireplace?
Vented (direct-vent) gas fireplaces pull combustion air from outside and exhaust it back outside through a sealed pipe—they're the safer, more universally recommended choice and the standard for real heat output. Vent-free units burn gas directly into the room without external venting; they're legal in Missouri but come with strict room-size and ventilation requirements, and they release some combustion byproducts into your living space. Given the tighter floor plans typical of Wellston's older homes, most local dealers steer homeowners toward direct-vent units, both for air quality and because they perform better as an actual heat source through a Missouri winter.
How often does a gas fireplace need to be serviced?
Plan on an annual inspection, ideally in early fall before you start using it regularly for the season. A technician checks the burner, pilot assembly, gas connections, and venting, and cleans the glass and interior—a service that typically runs $150 to $250 in the St. Louis metro area. This is far less involved than chimney sweeping for a wood-burning unit, but skipping it is still the most common reason gas fireplaces start acting up or triggering safety shutoffs mid-winter.
Gas vs. electric fireplace—which makes more sense for a Wellston home?
Gas delivers real, consistent heat output—enough to meaningfully offset a furnace during Wellston's colder stretches—and most models keep working during a power outage with battery or self-powered ignition. Electric fireplaces, running through Union Electric at about 12.6 cents per kWh, cost far less to install (often under $1,000), require no venting or gas line at all, and are a good fit for renters, upper-floor units in Wellston's duplexes, or homes without existing gas service. Wood isn't a realistic option for most lots here given how tightly the housing stock is built, which leaves gas and electric as the two practical paths—gas for real heat, electric for simplicity and low upfront cost.
Can I put a TV above my fireplace?
Yes—with an asterisk. Fireplaces are hot and TVs don't like heat. Either put a mantel between them to deflect rising warmth, or choose a fireplace with heat-management technology that creates a cool zone on the wall above—the wall stays around 125 degrees, barely warm, while the room still gets full heat. If you like clean lines and don't want a mantel, heat management is the answer.
Is my gas fireplace wasting gas?
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.
Can I install a fireplace myself?
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.
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.
