Real Heat for New Hampshire's Coldest Nights.

Most Franklin installations run $4,000 to $10,000, and because almost every home here runs on propane rather than piped natural gas, tank setup or delivery-line work is often part of that number. A propane insert going into an existing masonry fireplace—common in Franklin's older mill-era homes—with a tank already on-site tends to land on the lower end. A new direct-vent fireplace built into a remodel, with a fresh propane line run and a new outdoor tank, pushes toward the higher end. Local dealers will walk your home before quoting a firm number.

Franklin does not have widespread municipal natural gas service reaching most neighborhoods, so the overwhelming majority of gas fireplaces installed here run on propane. If you're used to natural gas from elsewhere, the main difference is fuel storage—you'll either tie into an existing propane tank or have one installed, sized by your dealer to match the fireplace's BTU draw plus any other propane appliances in the house. Every major gas fireplace model on the market can be configured for propane, so fuel type doesn't limit your options.

Yes, and it's a common project in Franklin's older housing stock, where many homes still have the original masonry fireplace and chimney from when the city was a working mill town. A propane insert typically runs $4,000 to $8,500 installed, using a stainless liner through your existing chimney as the vent path. The main variable is whether a new propane line and tank are needed or whether the home already has propane service for a furnace or water heater—homes already on propane are usually on the lower end.

Most will, and in Franklin that matters—ice storms and high winds off the Merrimack Valley regularly knock out power for a day or more, and residential electric rates here through PSNH and NH Electric Cooperative are already on the higher side. Units with intermittent pilot ignition (IPI) run on AA battery backup that kicks in automatically when the power drops, so keep fresh batteries on hand. Valor's gas fireplaces go a step further—their pilot's thermocouple generates the small amount of electricity the unit needs, so there's no battery to remember at all. Ask your local dealer which ignition system a given model uses before you decide.

With a long, demanding heating season and winter lows near 9°F, Franklin sits solidly in cold-climate heating territory, and drafty older homes need more output than the same square footage would in a milder climate. As a rough guide, a 20,000–30,000 BTU unit handles a single room or open living area, while 30,000–40,000 BTU units can serve as meaningful supplemental heat for a larger, leakier floor plan. A local dealer will factor in your insulation, ceiling height, and whether you want the fireplace as backup heat or the main heat source for a zone of the house.

Yes—the City of Franklin's building and code enforcement office requires a permit for gas fireplace installations, and propane line or tank work typically requires sign-off from a licensed gas fitter as well. Most local dealers handle both the building permit and the coordination with your propane supplier as part of the installation, so you're not left managing separate trades and separate inspections.

New Hampshire permits vent-free (ventless) gas fireplaces, but they come with strict room-size minimums and require an oxygen depletion sensor, since they release combustion byproducts directly into the living space. Vented direct-vent units, by contrast, draw combustion air from outside and exhaust it back outside through a sealed pipe—they're the more common and more universally recommended choice for Franklin homes, especially given how tightly sealed newer insulation retrofits can make older houses. Ask your dealer to walk through both options if you're weighing a smaller installation like a bedroom or den unit.

Plan on an annual inspection, typically before the heating season starts in the fall. A certified technician checks the burner, pilot assembly, propane connections, and venting, and cleans the glass and interior—usually $150 to $250 for the visit. This is a lighter lift than wood-stove chimney sweeping, but skipping it is the most common reason propane fireplaces start running rough or trip out on ignition.

Wood is still widely burned in this part of Merrimack County—maple, birch, beech, and oak are all common locally, and the White Mountain National Forest issues cutting permits for $20 per cord during the May-to-October season. Wood delivers strong heat output at low fuel cost and keeps working when the power's out. Gas, running on propane here since Franklin lacks municipal natural gas, offers instant on-off convenience, no hauling or ash cleanup, and—with the right ignition system—reliable operation during outages too. Many Franklin households run both: wood for the coldest stretches and heaviest heating load, propane gas for daily convenience in the main living space.

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.

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.

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.

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.
