Reliable Heat for Andover's Sub-Zero Nights.

Most Andover installations run between roughly $3,800 and $9,500. A direct-vent gas insert dropped into an existing masonry fireplace with a gas line already nearby sits at the lower end. A new direct-vent fireplace built into a wall for a basement remodel or new addition—with framing, venting through an exterior wall, and a fresh gas line run—lands in the middle to upper range. Homes on propane that need a new tank set can run higher once the propane supplier's install fees are added. A local dealer will confirm the number after seeing your space.

Yes, and it's a common request for the older housing stock in Andover's original neighborhoods that still have a wood-burning masonry fireplace from before the area's big subdivision growth in the 1990s and 2000s. A gas insert typically drops into that existing firebox, using the chimney as the vent path with a stainless liner. The look of the original brick surround stays, but the smoke, ash, and wood handling go away, along with a real jump in heat output. Expect the project to run similarly to a standard insert install once the liner and gas line work are included.

Either works fine. If your Andover home already has a gas furnace, range, or water heater, you almost certainly have natural gas mains service, and adding a fireplace on the same line is the simplest path. If you're on one of the newer or more rural parcels toward the edges of Anoka County that haven't been reached by gas mains, propane is the standard fallback—most gas fireplace models can be configured for either fuel with the correct orifice and regulator. Note that Connexus Energy, which serves electricity to much of Andover, is not a gas provider, so your gas or propane account will be separate from your electric bill.

Most modern gas fireplaces will, which matters here—Anoka County sees its share of winter storms that can knock out Connexus Energy service for hours at a time. Units with IPI (intermittent pilot ignition) run on battery backup and will still light on demand when the power's out, as long as the batteries are fresh. Valor fireplaces take a different approach: their pilot assembly generates its own electricity through the thermocouple, so there's no battery to remember at all. For a home that wants gas heat as genuine backup during an ice storm, that's worth asking your local dealer about directly.

A gas fireplace is a fully built-in unit framed into a wall—the right choice for new construction or a basement remodel without an existing hearth. A gas insert slides into an existing masonry fireplace opening and uses the existing chimney (with a liner) as its vent path—the common choice for Andover's older homes with a wood-burning fireplace already in place. A gas stove is a freestanding unit that sits on a hearth pad like a wood stove but runs on gas, which works well when you want supplemental heat in a room without an existing fireplace at all. A local dealer can tell you which fits your specific opening and framing.

Yes. New gas fireplace and insert installations require a building permit and a mechanical/gas permit through the City of Andover Building Department, and the gas line connection has to be run or inspected by a licensed gas-fitter. Most established hearth dealers in the area handle the permit filing and inspection scheduling as part of the installation, so it's rarely something the homeowner has to manage directly—but it's worth confirming it's included in your quote before work starts.

Vented, direct-vent units pull combustion air from outside and exhaust it back outside through sealed venting—that's the standard, code-friendly choice almost everywhere, including Andover. Vent-free (unvented) units are legal in Minnesota under specific room-sizing and ventilation rules, but they release combustion byproducts into the living space, which is a harder sell in a tightly-built, well-insulated modern home designed to hold heat through a long, demanding winter. For most Andover installations, a direct-vent unit is the safer and more efficient long-term choice, and it's what most local dealers will steer you toward for anything beyond a small supplemental unit.

Plan on an annual inspection, ideally in early fall before the heating season really starts. A technician checks the burner, pilot or ignition system, venting, and gas connections, and cleans the glass and interior. It's a lighter lift than chimney sweeping for a wood stove, but skipping it is how you end up with a pilot that won't hold or a burner that's sooting up the glass in January. Local gas appliance service providers typically charge somewhere in the $150–$250 range for this visit.

Wood and pellet stoves are uncommon in Andover—this is a built-out, fast-growing Anoka County suburb without the acreage, wood lots, or cutting-permit infrastructure that make wood heat practical in more rural parts of Minnesota. Natural gas mains reach most subdivisions here, electric service comes through Connexus Energy at a residential rate around 13.7 cents per kWh, and gas fireplaces deliver instant, thermostatically controlled heat without firewood storage or ash cleanup. For an Andover home, gas is the practical default; wood tends to show up only as a nostalgic choice on larger acreage properties toward the county's rural edges.

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 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.

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.
