Heat That Holds Through a Merrimack County Winter.

Wood is deeply rooted here—maple, birch, beech, and oak are cut and split locally, and cutting permits through White Mountain National Forest still send some households home with low-cost firewood every fall. With climate zone 6A and a winter heating season closer to Burlington, Vermont than to Boston, a cast-iron or steel wood stove that can hold an overnight burn matters for towns without easy propane delivery. Gas is common in and around Concord, where Liberty Utilities runs natural gas service; most of the rest of the county runs on propane delivery instead, and either way a gas fireplace or insert gives push-button heat without stacking wood. Pellet stoves are a strong middle option given regional supply from New England Wood Pellet and Lignetics—wood-style heat without the splitting and stacking. Electric fireplaces work well as supplemental heat for a bedroom or den, but they're not sized to carry a Merrimack County house through a January cold snap on their own. Most homes here run wood or pellet as primary heat with gas or electric backing up secondary rooms.

Yes, in nearly every case. New Hampshire doesn't handle building permits at the county level—each of Merrimack County's 27 towns and cities, from Concord and Franklin down to Hopkinton and Pittsfield, issues its own permits through its local building or code enforcement office. Wood stoves, wood inserts, gas fireplaces, gas inserts, and pellet stoves generally all need one, plus a post-install inspection. Gas work also requires a licensed gas technician and separate sign-off on the gas piping. Electric fireplaces are usually permit-free unless they involve new wiring or a built-in installation. Most hearth retailers pull the permit as part of the installation, but it's worth confirming with your specific town office, since small details vary from Concord to the smaller towns.

No—Merrimack County isn't in a non-attainment zone and doesn't see the winter temperature inversions that trigger burn bans in basin communities out West, so there are no mandatory curtailment days here. That said, new wood stoves still need to meet EPA 2020 NSPS emissions standards, and choosing a certified unit is worth it regardless of any rule: a modern EPA stove burning seasoned oak or maple puts out a fraction of the particulate matter of an old pre-1988 stove and pulls more heat out of the same cord of wood. If you're replacing an aging stove, that efficiency gain is the real reason to upgrade, not a regulatory requirement.

Several of the multi-fuel hearth shops based around Concord carry all four fuel types—wood, gas, pellet, and electric—under one roof, which helps if you're still deciding what fits your home. Smaller shops out in towns like Franklin or Hopkinton often specialize in two or three, typically wood and pellet, since those are the fuels in most demand outside the natural-gas footprint around Concord. If you're cross-shopping, a multi-fuel dealer can show working displays side by side and walk through what venting and clearances your specific house would actually need.

Merrimack County stretches from the built-up Concord area out to smaller towns like Warner, Andover, Sutton, and Danbury—a 30 to 40 minute drive in some directions. Technicians based around Concord and Franklin cover most of the county, but expect a modest trip fee for the more rural towns. Late summer into early fall is the best window to book chimney sweeps and gas inspections, since appointments tighten up once nighttime temperatures drop into the teens. If you're in one of the outlying towns, book early and keep a backup heat source on hand—a second fuel type or a generator for gas ignition systems—in case a winter storm delays a service call.

Wood stove or insert: roughly $4,000–$9,000 installed, higher for new construction requiring a full chimney build. Gas fireplace, insert, or stove: $4,500–$11,000, with the range driven mostly by whether new gas line or venting work is needed—lower if you're already on Liberty Utilities natural gas in the Concord area, higher if you're running propane and need a new tank and line. Pellet stove or insert: $4,000–$7,500 typical. Electric fireplace: $200–$3,000 for the unit itself, plus $400–$1,200 in labor for anything beyond a plug-and-play wall unit. For town-specific numbers, see the county + fuel pages above.

Match the fuel to your life, not the other way around. Wood: lowest fuel cost and total power-outage independence, but you're hauling and stacking. Gas: press a button, set a thermostat, no maintenance to speak of. Pellet: wood economics with automatic feeding, in exchange for weekly cleaning and a need for electricity. Electric: plugs in anywhere with honest supplemental heat. Nobody regrets the fuel that fits how they actually live.

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.

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.

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.
