On-demand heat for a damp Fundy cold that cuts deeper than the thermometer says.

Most projects run $6,000 to $15,000 CAD. A direct-vent insert dropping into an existing masonry firebox with a gas line already nearby, common in the older parts of Millidgeville closer to the Kennebecasis, lands toward the lower end. A new built-in unit for an addition or a home without existing gas service, requiring a fresh line run from the street and full venting through a wall or roof, pushes toward the top of that range. Your dealer's quote should include the municipal building department permit and the licensed gas-fitter work as part of the total.

It's a common request in this part of the Saint John Region, especially in older homes with masonry fireplaces originally built to burn sugar maple or yellow birch cut off a family woodlot. A gas insert typically slides into that existing firebox with a liner run through the current chimney, and most conversions land in the $6,000-$9,500 CAD range depending on how close you are to an existing Liberty Utilities line. If your current setup relies on an aging wood stove that would need a fresh WETT inspection to keep your insurance current, converting to gas sidesteps that requirement entirely.

Liberty Utilities, operating locally as Gas NB, serves Millidgeville and most of the built-up Saint John Region, so natural gas is a realistic option for the majority of addresses here rather than a rare exception. If your street falls just outside their distribution footprint, or you're further out toward the rural edges of the region, propane with a tank set is the standard fallback and most fireplace models a local dealer carries can be configured for either fuel.

Most will, and that matters here given how often Fundy coast storms and winter ice events knock out NB Power service for a day or more at a time. Units with intermittent pilot ignition run on AA battery backup that kicks in automatically. Some models, including certain Valor fireplaces, skip the battery altogether because the pilot's thermocouple generates its own current. Ask your dealer which ignition system is on any unit you're considering if outage resilience matters to your household.

A gas fireplace is a built-in unit framed into a wall, typical for new construction or a full renovation. A gas insert fits inside an existing masonry firebox, which is the common upgrade path in Millidgeville's older homes that still have a working chimney chase from their wood-burning days. A gas stove is freestanding on a hearth pad, similar in footprint to a wood stove but running off a gas line or propane tank instead of split maple or spruce. For most existing homes here, an insert is the least disruptive option.

Yes. You'll need a permit through the municipal building department, plus licensed gas-fitter work for the line itself, and the installation has to meet the CSA B365 code that applies to hearth appliances across New Brunswick. Most dealers who install in the Saint John Region handle the permit application and coordinate the final inspection as part of the job, so you're not managing two separate trades on your own.

Direct-vent units draw combustion air from outside and exhaust it back outside through sealed venting, which is code-compliant everywhere in New Brunswick and the safer, lower-maintenance choice for daily use. Vent-free units burn into the room and are legal but come with strict room-sizing limits. Given the damp, salt-air climate along the Kennebecasis and the Fundy shore, most local dealers steer Millidgeville homeowners toward direct-vent so moisture and combustion byproducts stay out of the living space entirely.

Plan on an annual check, ideally in late summer or early fall before the first real cold snap rather than mid-winter when technicians are booked solid. A tech checks the burner, pilot assembly, gas connections, and venting, and cleans the glass. It's a much lighter lift than sweeping a wood chimney, but skipping it on a unit that runs daily through a long Maritime heating season is how an ignition failure shows up on the coldest night in January. Budget roughly $150-$250 CAD for a standard visit.

Wood still has real advantages here—a DNRED cutting permit runs about $6.10 per cubic metre, or roughly $85 CAD for a full household allotment of up to 14 cubic metres, and sugar maple or yellow birch cut locally burns hot and keeps working without electricity during an outage. But wood appliances typically need a WETT inspection to satisfy your insurer, and Millidgeville's more suburban lots don't always leave room for a woodshed or a season's worth of stacked splits. Gas wins on convenience, on space, and on ignition at the flip of a switch, which is why it's become the default choice for a lot of newer homes in this part of the Saint John Region while wood stays popular in the older, more rural pockets nearby.

Most modern gas fireplaces can—turn it on and off from the couch with a remote, or set a room temperature and let the fireplace hold the comfort zone for you. If low maintenance matters to your family, this is the feature set that makes gas the convenience pick over wood and pellet.

Because a fireplace is an iceberg—there's more behind the wall than in front of it. A low quote often covers only the unit; the full scope includes vent pipe, gas line or electrical, framing, and the tile or stone that has to come off and go back on. Make every bidder price the whole job. If a dealer can't speak to the full scope with confidence, that's your signal to keep looking.

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.

Yes—with an asterisk. Fireplaces are hot and TVs don't like heat. Either put a mantel between them to deflect rising warmth, or choose a fireplace with heat-management technology that creates a cool zone on the wall above—the wall stays around 125 degrees, barely warm, while the room still gets full heat. If you like clean lines and don't want a mantel, heat management is the answer.
