Instant gas heat, built for Moline Acres winters.

A typical gas fireplace or insert installation in Moline Acres runs roughly $4,000 to $10,000, depending on the unit and whether a new gas line run from the meter is needed. Many homes here are older brick ranches with an existing masonry firebox, so a direct-vent gas insert with a stainless liner run up the existing flue tends to land on the lower-to-middle end. New construction, a built-in gas fireplace in a room without an existing chimney, or a long gas line extension from the street to the unit pushes costs toward the higher end. Local retailers will give you a firm number after an in-home walkthrough.

Yes, and it's one of the more common projects for homes in Moline Acres. Given the small lots typical of this part of St. Louis County and the lack of nearby woodlots for cutting or storing firewood, converting an old masonry fireplace to a sealed gas insert is often the practical move rather than trying to keep a wood-burning setup fed. The conversion typically runs $4,000 to $8,500, using your existing chimney as the venting path with a new liner, and tying into the Spire gas line already serving the house. It keeps the look of the original fireplace while adding real, controllable heat output.

Natural gas is the standard here—Spire Inc. serves essentially all of Moline Acres and the surrounding St. Louis County area, so most homes already have gas appliances and a line ready to extend to a fireplace. Propane is the exception rather than the rule in this part of the county, generally showing up only for detached outbuildings or properties that fall outside the gas service footprint. If you already run a gas water heater or furnace, adding a gas fireplace is usually a straightforward tie-in rather than a new fuel setup.

Most modern gas fireplaces will, which matters in this area since Union Electric Co. (Ameren Missouri) service can go down during winter ice storms that pass through the St. Louis region. Units with an IPI (intermittent pilot ignition) system run on a small battery backup that kicks in automatically, letting the fireplace light on demand even with the power out. Valor's gas fireplaces take it further—the pilot's thermocouple generates its own electricity, so there's no battery to remember to replace. Ask your local dealer which ignition system a given model uses if outage backup matters to you.

A gas fireplace is a fully built-in unit set into a framed wall or new construction. A gas insert is sized to slide into an existing masonry firebox, sealing it up and venting through the existing chimney with a liner—the common choice for the older brick homes found throughout Moline Acres. A gas stove is a freestanding cabinet-style unit that sits out on the floor like a wood stove but burns gas. For a home with an existing fireplace, an insert is usually the simplest upgrade; homes without one are better suited to a built-in unit.

Yes. Moline Acres is a small incorporated city, and building and gas permitting for a project like this is typically handled through the St. Louis County Department of Public Works rather than a standalone city building office, given the city's size. A licensed gas-fitter is required for the actual gas line work regardless of who pulls the permit. Most hearth retailers coordinate the permit, the gas line, and the final inspection as one package, so you're not left managing separate trades.

Vented (direct-vent) gas fireplaces pull combustion air from outside and exhaust the byproducts back outside through sealed venting—they're the cleanest and most universally code-compliant option. Vent-free units burn fuel directly into the living space without external venting; they're legal in Missouri but come with strict room-size and ventilation requirements, plus an oxygen depletion sensor. For most Moline Acres homes, direct-vent units are the more common recommendation since they deliver strong heat output without any tradeoff on indoor air quality—worth discussing with a local dealer if you're weighing the two.

Plan on an annual inspection, ideally before the coldest months set in. A technician will check the burner, pilot assembly, gas connections, and venting, and clean the glass and interior components. This is a much lighter job than chimney sweeping for a wood-burning unit, but it's what keeps a gas fireplace running safely and efficiently year after year. Local service providers typically charge $125 to $200 for a standard annual inspection.

Given that wood and pellet stoves are rare fits for the small lots and dense housing here, the real comparison for most Moline Acres homeowners is gas versus electric. A gas fireplace, tied into the Spire line most homes already have, delivers genuine heat output well-suited to the area's moderate winter heating season and 24°F average winter low—enough to meaningfully offset a furnace on cold nights. An electric fireplace, running on Union Electric Co. power at about 12.6 cents per kWh, is simpler to install, needs no venting or gas line, and works well for supplemental warmth or ambiance in a room where running gas isn't practical, but it won't match a gas unit's heat output during a real cold spell. Many homeowners here choose gas for a main living space and electric for a bedroom or den.

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.

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.

Yes—by creating a comfort zone. A furnace heats every square foot of the house just to warm the one room you're in; a gas fireplace on low burns roughly a sixth of the gas a typical furnace does. Set the furnace around 55–60 degrees as a baseline, then heat the rooms your family actually uses. Families who heat this way commonly save $20–$60 a month.

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.
