Keep Your Family Warm and Safe—No Matter What

For most Mehlville homes, no—not as a primary heat source. Natural gas is widely available and already built into the vast majority of homes here, and the region's winters (average low around 22°F, a moderate heating season) don't demand the kind of heavy-duty wood heating that colder climates rely on. Where a wood stove does make sense is as a secondary option: homeowners with an existing masonry fireplace who want a real heat source instead of a decorative one, or households that want a non-electric backup for winter ice storms. A local dealer can walk your specific house before you commit either way.

Because wood stove installs are infrequent in this part of St. Louis County, there isn't a deep local pricing history to point to, but expect the same broad range seen across the Midwest: roughly $3,500 to $8,000 for a freestanding stove with a new Class A chimney, or somewhat less—often $3,000 to $6,000—for a wood insert into an existing masonry fireplace that already has a working flue. Homes without an existing chimney will land at the higher end once framing and roof penetration are factored in. A local installer will give you a firm number after seeing the house.

New wood-burning appliance installations in unincorporated St. Louis County (which includes Mehlville) go through the St. Louis County Department of Public Works building permit process, and the stove itself needs to meet current EPA 2020 NSPS emissions standards. Since air quality restrictions here are minimal compared to non-attainment regions, there's no seasonal burn curtailment to worry about—but a permit and inspection are still required for the installation itself. Most local hearth dealers handle the permit paperwork as part of the job.

Missouri's oak-hickory forest belt runs right through the region, so oak, hickory, walnut, and maple are the standard species you'll find from local firewood suppliers around St. Louis County. Oak and hickory are the workhorses for heat output and long burn times if you're using a stove for real supplemental heat; maple and walnut burn a bit faster but season quicker. Expect to pay in the neighborhood of $200 to $275 per cord delivered, with well-seasoned hardwood commanding the higher end.

Yes, and it's usually the more sensible wood project for a Mehlville home compared to a full new stove install. If you have an older masonry fireplace—common in the pre-1970s housing stock around Lemay and Oakville—a wood insert with a stainless liner can turn a drafty, inefficient fireplace into an actual heat source, using the chimney you already have. It also keeps the footprint contained to the existing hearth, which matters in smaller ranch-style homes typical of the area.

This is probably the strongest local argument for wood in Mehlville. Union Electric (Ameren Missouri) service in St. Louis County can go down for extended stretches during winter ice storms, and a wood stove is one of the few heating options that keeps working with zero electricity—no furnace blower, no thermostat, no dependency on the grid. If that's your primary motivation, look at a simple non-catalytic stove rather than a high-tech unit with electronic controls, since simplicity is the whole point of a grid-independent backup.

For nearly all Mehlville homeowners, gas is the more practical everyday choice: it's already the standard heating fuel in this part of St. Louis County, installation is generally simpler where gas lines exist, and there's no wood to source, season, or haul. Wood's advantage is narrow but real—it keeps working when the power is out, and it suits homeowners who specifically want a solid-fuel fireplace for ambiance or an existing masonry hearth. If you're deciding purely on heating economics and convenience, gas wins here; if backup capability or a wood-burning aesthetic matters to you, wood is still a legitimate option.

Several firewood suppliers serve the greater St. Louis County area, delivering seasoned oak, hickory, and mixed hardwood by the cord, typically running $200 to $275 delivered and stacked. Since Mehlville doesn't sit near public forest land with self-cutting permit programs the way some western states do, buying seasoned wood from a local supplier is the standard route rather than cutting your own.

Electric fireplaces are a much more common addition in Mehlville than wood stoves, largely because they install almost anywhere with no venting, chimney, or gas line, and Union Electric's residential rate (around 12.5 cents per kWh) keeps operating costs reasonable for supplemental or ambiance use. A wood stove offers real heat output and works without power, but requires a chimney, clearances, and fuel handling that an electric unit doesn't. If you want ambiance and flexibility in a room without an existing fireplace, electric is the easier path; if you want genuine backup heat or you already have a masonry fireplace, wood is worth the extra effort.

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.

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.

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.

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.
