Instant heat for Grafton County's long, cold winters.

Most gas fireplace and insert installations in this region run somewhere between $4,000 and $10,000, depending on the unit, the venting path, and whether new gas or propane line work is required. A direct-vent insert dropped into an existing masonry fireplace with fuel already available nearby sits toward the lower end. A new built-in gas fireplace in a remodel—with framing, venting, and a fresh propane line or tank installation—runs higher. Homes in Lincoln, Woodstock, or other outlying towns without an existing propane setup should budget for tank installation as a separate line item. A local dealer can give you a firm number after an in-home look at your chimney or wall cavity.

Yes—it's one of the more common projects for older homes around Hanover, Plymouth, and Littleton that still have a masonry fireplace built decades ago for wood. A gas insert typically drops into the existing firebox and vents through a new stainless liner run up your current chimney, so you're not tearing into walls. Whether you run natural gas or propane depends on where you live in the county; either way, the conversion keeps the look of your existing hearth while giving you real, controllable heat instead of an open, heat-losing fireplace.

Propane is the more practical answer for most of Grafton County. Liberty Utilities runs natural gas service through the Lebanon and Hanover area of the Upper Valley, so homes there can often tie into an existing gas line. Everywhere else—Plymouth, Littleton, Lincoln, Woodstock, and the smaller towns scattered through the White Mountains—propane is the standard, either from an existing household tank or a new tank set by a local supplier. Nearly every gas fireplace on the market can be configured for either fuel; your installer sets the correct orifice and regulator for whichever you're running.

Most will, which matters in a county where ice storms and downed lines can leave rural roads without power for days. Units with IPI (intermittent pilot ignition) include a battery backup—typically AA batteries inside the unit—that keeps the pilot lighting on demand even when the grid is down. Valor fireplaces take a different approach: their pilot assembly generates its own electricity through the thermocouple, so there are no batteries to remember at all. For homes in Woodstock, Lincoln, or other spots where outages tend to run long, ask your local dealer which ignition system a given model uses before you buy.

A gas fireplace is a fully built-in unit, framed into a wall—the right call for new construction or a major remodel. A gas insert is built to slide into an existing masonry firebox, using your current chimney as the vent path, which is common in Grafton County's older farmhouses and colonials. A gas stove is freestanding, sitting on the floor like a wood stove but running on gas or propane instead—a good option if you want zone heat in a room with no existing fireplace and don't want to frame in a built-in unit. Most homeowners with an existing fireplace they want to upgrade land on an insert.

Yes, but it's handled at the town level, not the county—Hanover, Lebanon, Plymouth, Littleton, and every other Grafton County town issues its own building and gas permits through its local building inspector's office. If you're running a new propane tank, there are also setback and placement rules to follow, which your propane supplier or installer will know. Most local hearth dealers coordinate the permitting, gas line or tank work, and inspection as part of the installation, so you're not chasing down multiple trades yourself.

Vented gas fireplaces—direct-vent or B-vent—pull combustion air from outside and exhaust the byproducts back outside through sealed venting. Vent-free units burn directly into the room without external venting, which is more efficient on paper but releases water vapor and small amounts of combustion byproducts into your living space. Vent-free models are legal in New Hampshire with proper room-sizing and oxygen depletion sensors, but for a climate zone 6A county with a long, demanding heating season, most homeowners here want real, sustained heat output—which favors a direct-vent unit. Ask your local dealer to walk you through both if you're weighing the tradeoff.

Plan on an annual inspection, ideally before heating season starts in the fall. A certified technician checks the burner, pilot assembly, venting, and gas connections, and cleans the glass and interior—a lighter job than a wood chimney sweep, but just as important for safe operation. Expect to pay somewhere in the $150 to $250 range for a standard annual service call from a local gas appliance technician.

Wood has real staying power in Grafton County—maple, birch, beech, and oak are all common locally, and cutting permits through the White Mountain National Forest run about $20 per cord during the May-to-October season, which keeps fuel cheap for anyone willing to cut and split their own. Wood also keeps working when the power goes out, which matters given the county's ice storms. Gas trades that self-sufficiency for convenience: instant on-off heat, no ash or creosote, and a cleaner look, though a vented unit still needs a fuel source (natural gas near Lebanon and Hanover, propane almost everywhere else). Many Grafton County homes end up with both—wood for the deep-winter backup, gas for the everyday 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.

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.

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.

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.
