Instant Warmth for Delaware County's Older Homes.

Most gas fireplace and insert installations in Swarthmore run between roughly $4,000 and $10,000, with the wide range driven mainly by two things: whether a gas line already reaches the room, and whether the install is a straightforward insert into an existing masonry fireplace versus a new direct-vent unit requiring fresh venting through an exterior wall. Given how many Swarthmore homes have original brick fireplaces from the early 1900s, insert conversions into an existing chimney tend to land on the lower-to-middle end of that range, since the masonry opening and flue are already in place.

Yes—it's one of the most common projects for Swarthmore's older housing stock. A direct-vent gas insert slides into the existing masonry opening and typically vents through a stainless liner run up the original flue, so the exterior appearance of the fireplace doesn't change. The main variable is gas line access: homes on streets already served by PECO natural gas usually just need a line run from an existing appliance circuit, while a handful of older or more rural-edge properties in Delaware County rely on propane instead. Either way, a local hearth dealer can confirm what your specific chimney and gas service will support before you commit to a unit.

Most of Swarthmore borough is served by PECO natural gas, which makes it the default choice for the majority of homeowners here—if your home already has a gas water heater, range, or furnace, adding a fireplace typically just means an additional gas line run to the fireplace location. A smaller number of properties on the outer edges of the borough or in less densely served pockets of Delaware County may rely on propane, which works with the same fireplace models via a different orifice and regulator setup. Your local dealer can tell you which service reaches your specific address.

Most gas fireplaces sold today use intermittent pilot ignition (IPI) with a small battery backup, so they'll still light and run during a power outage—you just want to keep fresh AA batteries in the unit, since it's easy to forget until you actually need it. Valor fireplaces take a slightly different approach: their pilot assembly generates its own electricity through a thermocouple, so there's no battery to maintain at all. Given that PECO's overhead lines through Delaware County can go down in ice storms and nor'easters, that kind of self-powered ignition is worth asking about if outage-proof heat matters to you.

A gas fireplace is a fully built-in unit framed into a wall—the right choice for new construction or a room without an existing hearth. A gas insert is sized to slide into an existing masonry fireplace opening, which describes most of the older homes around Swarthmore College and the borough's historic districts. A gas stove is a freestanding cast-iron or steel unit that sits on the floor and vents through a wall or existing chimney, useful in smaller rooms or additions that never had a fireplace to begin with. For the typical Swarthmore colonial or Victorian with an existing brick hearth, an insert is almost always the simplest and most cost-effective path.

Yes—Swarthmore Borough requires a building permit for gas fireplace installations under Pennsylvania's Uniform Construction Code, and the gas line work itself needs to be done by a licensed gas-fitter. In practice, most local hearth dealers handle the permit application and coordinate the gas line and venting inspections as part of the installation, so homeowners typically aren't filing paperwork themselves. It's worth confirming with your installer that the permit has actually been closed out, especially on older homes where existing chimney or flue conditions can trigger additional inspection requirements.

Vented (direct-vent) gas fireplaces draw combustion air from outside and exhaust it back outside through sealed venting—they're the standard, code-friendly choice everywhere, including Pennsylvania. Vent-free units burn gas directly into the room without external venting; they're legal in PA but come with strict room-sizing rules and oxygen-depletion sensors, and they release some water vapor and combustion byproducts into the living space. Given how many Swarthmore homes are older and tightly built after retrofit insulation and window upgrades, a direct-vent unit is generally the safer, more comfortable choice—it won't add humidity or combustion gases to an already snug older house.

Plan on an annual inspection, ideally in early fall before the heating season starts. 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 since a dirty pilot or misaligned burner is the most common cause of a fireplace that won't light reliably. Local gas appliance service providers typically charge in the $150–$250 range for this visit.

For most Swarthmore homes, no—wood heating is genuinely uncommon in the borough. There's no nearby national forest with cutting permits, most lots don't have room for stacked cordwood, and Swarthmore's mild climate zone (4A, with a moderate winter heating season) doesn't demand the kind of all-night radiant heat that makes wood the right call in colder places like Burlington, VT. A handful of homeowners do keep an existing wood fireplace for occasional ambiance, but for practical, everyday heat in an older Delaware County home, a direct-vent gas insert is almost always the better fit.

Most fireplaces are a thin metal box—they heat fine, but you rely on the fan to move the warmth into the room. Radiant models use a thick cast-ceramic firebox, about an inch and a quarter thick, that soaks up the fire's heat and radiates roughly 25–30% more warmth into the room with no fan running. If you watch TV in the same room or want heat in a power outage, radiant is worth asking about.

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.

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.

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.
