Instant heat for Montgomery County winters.

A typical gas fireplace or insert installation in Montgomery County runs roughly $3,500 to $9,500, depending on the unit, the venting path, and whether new gas line work is required. Converting an existing masonry fireplace to a direct-vent gas insert—common in Clarksville's older neighborhoods—tends to land on the lower end when a gas line is already nearby. New construction or additions without existing gas service, especially homes that need a line run from the street or a propane tank set, push toward the higher end. A local dealer will give you a firm number after an in-home look at your venting and gas access.

Yes, and it's one of the more common projects in Clarksville's older housing stock, where open masonry fireplaces built decades ago are common but rarely used for daily heat anymore. A gas insert slides into the existing firebox and vents through the chimney with a stainless liner, so you keep the look of the original fireplace while gaining real, controllable heat output. Cost typically falls in the $4,500 to $8,500 range locally, depending on whether the home already has a nearby gas line or needs one extended from the meter.

Either works, and the right choice mostly comes down to where you live in the county. Inside Clarksville and the immediate suburbs, Clarksville Gas and Water provides natural gas service to most neighborhoods, so if your home already has a gas water heater or furnace, adding a fireplace is a simple tie-in. Farther out toward the rural parts of Montgomery County, propane from a local supplier is the standard fallback, delivered to a tank on the property. Nearly every gas fireplace model on the market can be configured for either fuel—your installer sets the correct orifice and regulator for whichever you have.

Most will, with the right ignition system. Units with intermittent pilot ignition (IPI) include a battery backup—typically standard AA batteries inside the unit—that keeps the fireplace lighting on demand even when the power is out, which matters during the ice storms and severe weather that occasionally roll through Montgomery County. Valor fireplaces take a slightly different approach: their pilot generates its own electricity through the thermocouple, so there are no batteries to remember or replace. Ask your local dealer which ignition system is on any model you're considering if outage backup matters to you.

A gas fireplace is a fully built-in unit, framed into a wall for new construction or a remodel. A gas insert is sized to slide into an existing masonry fireplace opening, converting an old wood-burning hearth into a sealed, efficient gas unit using the existing chimney as the vent path. A gas stove is a freestanding cast-iron or steel unit that sits on the floor, similar in footprint to a wood stove but burning gas. In Montgomery County, where many homes—especially in Clarksville's older neighborhoods—already have a masonry fireplace, an insert is usually the natural fit. Newer homes and additions without an existing firebox typically go with a built-in fireplace instead.

Yes—both a building permit and a gas line permit are generally required for a new gas fireplace or insert installation, whether you're inside Clarksville city limits or in unincorporated Montgomery County. Permits are handled through the applicable local building and codes office, and gas line work specifically has to be done by a licensed gas-fitter. Most established hearth dealers coordinate all of this as part of the install, so you're not left managing separate trades and inspections yourself.

Vented gas fireplaces (direct-vent or B-vent) pull combustion air from outside and exhaust the byproducts back outside through sealed venting—they're the cleaner, more universally code-friendly option. Vent-free (ventless) units burn fuel directly into the room without any outside venting, which makes them easier to install in spaces without an existing chimney or vent path, but they release some water vapor and combustion byproducts indoors and come with strict sizing and ventilation rules. Tennessee permits vent-free units, and they show up in Montgomery County homes where running a vent isn't practical, but most local dealers steer larger installations and primary living spaces toward direct-vent units for better real-world performance and indoor air quality.

An annual inspection is the standard recommendation for any gas fireplace or insert. A technician checks the burner, pilot assembly, venting, and gas connections, and cleans the glass and interior—a much quicker job than a wood chimney sweep, but just as important for safe operation. Local service providers in the Clarksville area typically charge in the $150 to $250 range for this annual visit, and it's worth scheduling before the coldest stretch of winter each year.

Given the county's mild climate—a fairly short, mild winter heating season and winter lows that average around 28°F—most homeowners here choose gas for the convenience of instant, thermostat-controlled heat without the work of a wood pile. Wood is still an option; local oak, hickory, and pine burn well in a traditional fireplace, and a small number of rural properties keep a wood stove for backup heat or ambiance. But new wood-burning installations are relatively uncommon in Montgomery County compared to colder parts of the country, and pellet stoves see similarly limited local demand despite regional pellet brands like Lignetics and Hamer Pellet Fuel being available. For most homes here, gas offers the better balance of comfort and low maintenance.

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.

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.

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.

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.
