Flip a Switch, Feel the Heat—Right Here in Drexel Hill.

For a direct-vent gas insert into an existing masonry fireplace—the most common project in Drexel Hill's older twins—expect roughly $4,000 to $9,000, with the low end applying to homes that already have a gas line nearby and the high end covering a full liner, new gas run, and higher-end unit. A built-in gas fireplace for a room addition or basement finish, where framing and venting have to be built from scratch, typically runs higher, in the $6,000 to $12,000 range. A local installer will size the gas line and venting for your specific twin or Colonial and give you a firm number after an in-home look.

Yes, and it's the most common gas project in Drexel Hill. Most of the twins and Colonials here built from the 1920s through the 1950s came with a masonry wood-burning fireplace that many owners no longer use—a gas insert with a stainless steel liner runs through that same chimney, so you keep the look of the original firebox while gaining real, controllable heat output. Since PECO gas service already reaches most of these blocks, the main cost driver is usually how far the nearest gas line is from the fireplace, not whether gas is available at all.

Drexel Hill sits solidly inside PECO's natural gas service territory, so the overwhelming majority of homes here already have gas service for the furnace, water heater, or range. Propane is uncommon as a primary fireplace fuel in this part of Delaware County—you'll mostly see it used for grills or standalone outdoor appliances rather than indoor fireplaces. If your home already has gas heat or a gas range, adding a fireplace is almost always a natural gas hookup, not a propane tank installation.

Most modern gas fireplaces will, with the right ignition system. Units with IPI (intermittent pilot ignition) run on AA battery backup that kicks in the moment PECO power drops, so the fireplace lights on demand just like normal. Valor fireplaces go a step further—their pilot generates its own electricity through the thermocouple, so there are no batteries to remember at all. Drexel Hill doesn't see outages as often or as long as more exposed rural areas, but ice storms and downed lines do happen here in winter, and a battery-backed or self-powering gas fireplace is genuine backup heat when the furnace's blower motor won't run.

A gas fireplace is a fully built-in unit framed into a wall—the right choice for a basement finish or new addition without an existing firebox. A gas insert slides into an existing masonry opening and uses the chimney as its vent path, which fits perfectly with the original fireplaces found in most of Drexel Hill's older twins. A gas stove is a freestanding cabinet-style unit that sits on the floor and vents out a nearby wall—a good option for a room with no chimney at all, like a converted garage or sunroom. For most homeowners here with an existing firebox they want to bring back to life, the insert is the natural fit.

Yes. Drexel Hill is unincorporated and falls under Upper Darby Township, so permits go through the Upper Darby Township Building & Housing Department, which requires both a building permit for the appliance installation and a gas permit for any new or modified gas line. The gas line work has to be done by a licensed gas fitter—one of the main reasons homeowners hire a certified hearth dealer rather than a general handyman, since the dealer coordinates the gas work, venting, and inspection as one job instead of leaving you to manage separate trades.

Vented (direct-vent) gas fireplaces pull combustion air from outside and exhaust it back outside through a sealed pipe—they're the cleanest, safest option and produce real, substantial heat. Vent-free gas fireplaces burn without any outside venting at all, releasing some water vapor and combustion byproducts into the room; Pennsylvania permits them, but they're governed by strict room-size and ventilation rules. In Drexel Hill's older, well-sealed twins—many with updated insulation and newer windows—that indoor air quality tradeoff matters more than it would in a drafty older farmhouse. Most local dealers steer homeowners toward direct-vent units for exactly that reason, and it's worth asking about both options before you decide.

Plan on an annual inspection, ideally in early fall before regular winter use starts. A technician checks the burner, pilot assembly, venting, and gas connections, and cleans the glass and interior—a much lighter job than a wood chimney sweep, but just as important for safety. Local gas appliance technicians typically charge $150 to $250 for this service, and it's the kind of maintenance that's easy to skip until a unit won't light reliably or the glass fogs from incomplete combustion.

Wood isn't really part of this conversation in Drexel Hill—there's no nearby forest land, no cutting permits, and most original fireplaces in the older twins here have already been converted or sit unused. The real choice is gas versus electric. Gas, run off PECO's existing natural gas network, delivers real radiant heat and works during power outages with the right ignition system, making it the better pick for a primary or supplemental heat source in a main living area. Electric fireplaces install for far less—often under $1,500—need no venting or gas line at all, and are the practical choice for a rental, a condo, or a room where running gas isn't feasible. At PECO's residential rate of about 14.7 cents per kWh, electric costs more per BTU to run than gas, so most homeowners here choose gas for daily heating and save electric units for smaller rooms or purely decorative use.

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.

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.
