Steady gas heat for Clark County's cold Illinois winters.
With winter lows averaging 17°F and a solid six-month heating season, Clark County homes need reliable heat that doesn't depend on tending a fire. We'll match you with a trusted local dealer who can size the right gas fireplace, insert, or stove for your home.
Every Project Starts From One of These Five Situations
Instant heat without the wood pile.
Clark County sits in east-central Illinois along the I-70 corridor, a mix of farmland, small towns, and older housing stock in Marshall, Casey, Westfield, and Martinsville. With average winter lows in the upper teens, the county's climate is real but not extreme—nowhere near what a place like Duluth, Minnesota or Bismarck, North Dakota deals with, but cold enough for a six-month heating season where a dependable, low-maintenance heat source matters.
Many farmhouses and older homes throughout the county still have a functioning masonry fireplace that rarely gets used because tending a wood fire isn't practical for daily heat. Converting that fireplace to a direct-vent gas insert is one of the most common projects local dealers handle here—it keeps the existing chimney doing the work while turning an ornamental hearth into a real heat source you can flip on during a January cold spell. Natural gas lines generally serve the incorporated town centers, while propane tanks are the standard fuel source for homes out in the unincorporated stretches of the county—either way, a local dealer will know which setup fits your address.

Frequently Asked Questions
How much does a gas fireplace installation cost in Clark County?
A typical gas fireplace or insert installation in Clark County runs roughly $3,800 to $9,500, depending on the unit, the venting path, and whether new gas line work is needed. A direct-vent insert going into an existing masonry fireplace with gas already run to that wall sits at the lower end. A new built-in gas fireplace for a remodel, or a home that needs a fresh gas line or a new propane tank set, runs toward the higher end. A local dealer will give you a firm number after seeing your chimney or wall configuration in person.
Can I convert my existing wood fireplace to gas?
Yes, and it's a common request in a county where a lot of the housing stock is older farmhouses with a masonry fireplace that's more decorative than functional at this point. A gas insert slides into the existing firebox and vents through a stainless liner run up your current chimney, so you keep the look of the fireplace while gaining real, controllable heat. Cost typically lands in the $3,800 to $8,000 range locally, with propane conversions running slightly higher if a new tank or regulator setup is required.
Do I need natural gas, or can I run a fireplace on propane?
Either works, and which one you use mostly comes down to where your house sits. Homes inside Marshall, Casey, and the other town centers are more likely to have natural gas service already run for a furnace or water heater, which makes adding a fireplace straightforward. Homes on the county's rural roads and farm lots typically run on propane, either from an existing tank or one installed as part of the project. Most gas fireplace and insert models can be configured for either fuel—your dealer sets the correct orifice and regulator for whichever you have.
Will my gas fireplace still work if the power goes out?
Most modern direct-vent gas fireplaces will, which matters in a county that sees its share of winter ice storms knock out rural power lines. Units with intermittent pilot ignition (IPI) run on a small battery backup that kicks in the moment power drops, so the fireplace lights and operates normally. A few brands, including Valor, generate their own power off the pilot flame's thermocouple and don't need batteries at all. Ask your local dealer about the ignition system on any model you're considering if backup heat during an outage is a priority for your household.
What's the difference between a gas fireplace, gas insert, and gas stove?
A gas fireplace is a fully built-in unit framed into a wall, typically used in new construction or a remodel where there's no existing chimney. A gas insert is built to slide into an existing masonry fireplace opening, converting that firebox into a sealed, efficient heat source using the chimney you already have. A gas stove is a freestanding cabinet unit, similar in footprint to a wood stove, that can sit against nearly any wall with the right clearances. For the many Clark County homes with an existing but underused fireplace, an insert is usually the simplest and most cost-effective upgrade.
Do I need a permit to install a gas fireplace in Clark County?
Generally yes—new gas fireplace and insert installations typically require a building permit and gas line inspection through Clark County's building department, and propane tank installations are usually subject to their own placement and setback rules from your propane supplier. Most established local hearth dealers handle the permit paperwork and coordinate the licensed gas-fitter as part of the install, so you're not left juggling separate trades and inspections on your own.
What's the difference between vented and vent-free gas fireplaces?
Vented (direct-vent or B-vent) gas fireplaces pull combustion air from outside and exhaust the byproducts back outside through sealed venting—they're the standard, code-compliant choice everywhere. Vent-free units burn fuel directly into the room without exterior venting, which makes them easier to place but means combustion byproducts stay in the living space, so they come with strict room-size and ventilation requirements. Vent-free units are legal in Illinois, but for Clark County homes, direct-vent is the far more common recommendation from local dealers—it delivers real heat output without any tradeoff on indoor air quality.
How often should a gas fireplace be serviced?
Plan on an annual inspection, ideally before the heating season starts in the fall. A technician checks the burner, pilot assembly, venting, and gas connections, and cleans the glass and interior—a much quicker visit than a wood-stove chimney sweep, but just as important for safety and for keeping the flame pattern looking right. Local service providers in the area typically charge somewhere in the $125 to $225 range for this visit.
Gas vs. wood—which makes more sense for a Clark County home?
Wood offers lower fuel costs if you're already working oak, hickory, walnut, or maple off your own property, plus the ability to keep heating during a power outage. Gas offers instant on-off convenience, no ash or creosote to manage, and steady output without having to feed a fire—a real advantage for households where daily wood-tending just isn't practical. Plenty of homes in the county run both: a gas insert or stove for daily use in the main living space, and an old wood fireplace or outdoor setup kept around for backup or ambiance. A local dealer can walk through both options against your specific home.
Why is a fireplace insert so efficient?
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.
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.
Does a fireplace add value to my home?
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.
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.
