Instant Heat for Union County's Cold Central-Ohio Winters.

Costs vary with the unit, the venting path, and whether new gas line work is needed, but a typical direct-vent gas fireplace or insert installation in Union County generally runs somewhere between $3,800 and $10,000. A gas insert dropped into an existing masonry fireplace with a gas line already nearby sits toward the lower end. A new built-in fireplace in a Marysville-area new-construction home—with framing, venting, and a fresh gas line run from the meter—lands toward the middle or higher end. Rural homes needing a new propane tank installation or a longer gas line extension can run higher still. A local dealer will give you a firm number after seeing your home.

Yes—it's a common project for the older farmhouses scattered through Union County's townships, many of which still have a masonry fireplace built decades ago for burning local oak or hickory. A gas insert typically slides into the existing firebox, running a stainless liner up the current chimney as the vent path. Cost usually falls in the $3,500-$8,500 range depending on whether the home already has a gas line nearby or needs one run from the street or a new propane tank. The result keeps the look of the original fireplace while replacing the ash, smoke, and constant tending with a switch or remote.

Either works, and which one you use mostly comes down to where in the county you live. Columbia Gas of Ohio serves Marysville, Plain City, and most incorporated areas, so if your home already has natural gas for a furnace or water heater, adding a fireplace on the same line is usually simple. Outside those service areas—much of rural Union County, including areas around Richwood and Magnetic Springs—propane from a local supplier is the standard fallback, either from an existing tank or a new one set specifically for the fireplace. Most gas fireplace models can be configured for either fuel; your installer sets the correct orifice and regulator for whichever you have.

Most will, with the right ignition setup. Units with IPI (intermittent pilot ignition) include a battery backup—typically standard AA batteries inside the unit—that keeps the fireplace lighting on demand even when the power's out. Given how many Union County winters bring at least one ice storm or extended outage in the outlying townships, that's worth asking about specifically. Valor fireplaces take a different approach: their pilot assembly generates its own electricity through the thermocouple, so there's no battery to remember at all. Ask your local dealer about ignition type on any unit you're considering, especially if you're outside Marysville proper where outages tend to run longer.

A gas fireplace is a fully built-in unit framed into a wall—the natural choice for the newer construction going up around Marysville as the county grows. A gas insert is built to slide into an existing masonry firebox, which fits the older farmhouses common in Union County's rural townships. A gas stove is a freestanding cabinet-style unit that sits on the floor like a wood stove but runs on gas, useful when you want zone heat in a room without an existing hearth or the framing for a built-in. Most homeowners with an existing fireplace go with an insert; new-construction and remodel projects usually call for a built-in unit.

Yes—both a building permit and a gas line permit are typically required for a new gas fireplace installation, whether you're inside Marysville city limits (permits through the city building department) or in unincorporated Union County (through the county building department). The gas line connection itself needs to be run or inspected by a licensed gas-fitter. Most established local dealers coordinate all of this as part of the install, so you're not left managing separate trades and separate inspections yourself.

Vented gas fireplaces—direct-vent or B-vent—pull combustion air from outside and exhaust the byproducts back outside through a sealed pipe. Vent-free units burn directly into the room with no external venting, which is more efficient on paper but releases some water vapor and trace combustion byproducts into the living space. Ohio permits vent-free units with restrictions on room size and required oxygen-depletion sensors, but for Union County's well-insulated modern homes and older farmhouses alike, direct-vent units are by far the more common and more broadly recommended choice—full heat output with no indoor air quality tradeoffs. A local dealer can walk you through both if you want to weigh the options.

Plan on an annual inspection, ideally before the heating season ramps up in the fall. A technician checks the burner, pilot assembly, venting, and gas connections, and cleans the glass and interior—a much lighter service than wood chimney sweeping, but still important for safety and efficiency. Most local gas appliance service providers in the Marysville and Union County area charge in the $150 to $250 range for a standard annual visit.

Wood has deep roots in the county's rural townships, where oak, hickory, maple, and cherry are all common on local woodlots, and a wood stove or insert keeps working during a power outage with no electricity required. Gas trades that self-sufficiency for convenience: instant on-off heat, no ash or wood handling, and a consistent flame that suits the busier pace of Marysville's growing subdivisions. Union County has no air quality non-attainment restrictions, so neither fuel faces burn curtailment concerns—the choice really comes down to whether you value the ritual and backup capability of wood or the low-maintenance convenience of gas. Plenty of local homes end up with both: gas in the main living space, wood as a backup or secondary heat source elsewhere on the property.

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.

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.

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.
