Warm, instant heat for Belknap County's long Lakes Region winters.

A typical gas fireplace installation in Belknap County runs between $4,500 and $10,500, depending on the unit, venting path, and whether new propane tank or gas line work is needed. A direct-vent insert going into an existing masonry fireplace with propane already on site sits at the lower end. New construction or a built-in gas fireplace requiring fresh venting and a new propane tank setup—common for camps around Lake Winnipesaukee being converted to year-round use—runs toward the higher end. Properties on the far side of the lake or up long private roads in Alton or Gilmanton may see a modest travel surcharge from installers.

Yes, and it's a common project in older Laconia and Meredith homes with an existing masonry fireplace. A gas insert goes into the existing firebox, using a stainless liner run through your current chimney as the vent path. In Belknap County this typically runs $4,500 to $9,000, with cost driven mostly by whether propane service already reaches the home and whether new gas line work is needed from an outdoor tank. The conversion keeps the look of your original hearth while eliminating ash cleanup and giving you push-button heat on the coldest nights of a 7,100-HDD winter.

For most of Belknap County, propane is the practical answer. Natural gas mains don't extend meaningfully into this part of the Lakes Region, so homes in Laconia, Gilford, Meredith, Alton, Belmont, Sanbornton, and Tilton almost always run gas fireplaces off a propane tank, whether that's an existing tank shared with a furnace or water heater, or a new tank installed by a regional supplier. Nearly every gas fireplace model on the market can be configured for propane—your local dealer sets the correct orifice and regulator during install, so fuel choice rarely limits which unit you can get.

Most modern gas fireplaces will, which matters in a region where nor'easters and ice storms regularly knock out power for days at a time. Units with IPI (intermittent pilot ignition) run on battery backup—typically a set of AA batteries inside the unit—that kicks in automatically when the power drops, so the fireplace still lights on demand. Valor takes it a step further: their fireplaces generate their own electricity from the pilot's thermocouple, so there are no batteries to remember at all. For lakefront camps in Belknap County that sit empty for stretches in the off-season, that self-powering design is worth asking about specifically.

A gas fireplace is a fully built-in unit framed into a wall, typically used in new construction or a remodel. A gas insert slides into an existing masonry fireplace opening, converting it into a sealed, high-efficiency unit that vents through the existing chimney. A gas stove is a freestanding cast-iron or steel unit that sits on a hearth pad like a traditional wood stove but burns gas. In Belknap County's older lake-town housing stock, where many homes already have a working masonry fireplace, an insert is usually the most cost-effective upgrade. Newer construction and camps without an existing chimney tend to go with a built-in fireplace or freestanding stove instead.

Yes—but permitting in New Hampshire happens at the town level, not the county. Laconia, Gilford, Meredith, Alton, Belmont, Sanbornton, and Tilton each maintain their own building department, and a new gas fireplace installation typically needs both a building permit and a gas permit pulled by a licensed gas fitter. Most local hearth dealers coordinate this as part of the installation, including inspection sign-off, so homeowners generally don't have to navigate the town office themselves.

Vented gas fireplaces—direct-vent or B-vent—draw combustion air from outside and exhaust combustion byproducts back outside through a sealed vent. Vent-free units burn fuel directly into the room with no external venting, which is more efficient on paper but releases some moisture and combustion byproducts into the living space. New Hampshire doesn't prohibit vent-free units, but for Belknap County's long, cold heating season, direct-vent models are the more common and more strongly recommended choice—they put out serious heat without any tradeoff on indoor air quality, which matters in a tightly sealed lake house closed up for a long winter.

Plan on an annual inspection, ideally before the heating season starts in the fall. A technician will check the burner, pilot assembly, venting, and any gas connections, and clean the glass and interior components. This is a lighter lift than wood chimney sweeping but just as important for safety and efficiency—most Belknap County gas service providers charge in the $150 to $250 range for a standard annual visit.

Wood heat still runs deep here—local maple, birch, beech, and oak are common firewood species, and Forest Service cutting permits through the White Mountain National Forest run about $20 per cord during the May-to-October season, which keeps self-cut firewood affordable for rural and lake-area homes. Wood also keeps working without power, which matters through Belknap County's ice storms. Gas wins on convenience: instant on-off heat, no ash or wood handling, and a cleaner look for primary living spaces. Many homes in the county end up with both—gas in the main room for daily use and a wood stove elsewhere as backup heat when the power goes out.

An insert does two things: it seals the chimney completely, so you stop losing air you already paid to heat, and it radiates warmth into the room through the firebox and glass. Most add a heat-exchange fan that pulls cool room air underneath, wraps it around the hot firebox, and pushes it back out warm. Your home is more efficient before you've even lit the first fire.

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.

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.
