Instant heat for Polk County's coldest nights.

Most gas fireplace and insert installations in Polk County run roughly $3,500 to $10,000, depending on the unit, the venting path, and whether new gas line work is required. A direct-vent gas insert dropped into an existing masonry fireplace in a Des Moines or West Des Moines home that already has gas service nearby tends to land on the lower end. A new built-in gas fireplace for a remodel or new-construction great room in Ankeny or Waukee-adjacent Polk County neighborhoods—with framing, venting, and a fresh gas line run—sits higher. A local dealer will give you a firm number after an in-home walk-through.

Yes, and it's one of the more common projects local hearth dealers handle across Polk County. Plenty of homes built in the 1970s through 1990s in Des Moines, Urbandale, and Clive came with a standard open masonry firebox that rarely gets used for an actual wood fire. Converting it to a direct-vent gas insert reuses the existing chimney chase with a stainless liner, typically runs $4,000 to $8,500, and turns an underused feature into a fireplace the household will actually rely on through the winter. Given how uncommon new wood-burning installs are in this metro, conversion to gas—rather than restoring the wood option—is by far the more requested route.

MidAmerican Energy provides natural gas service across the vast majority of Polk County, including Des Moines, West Des Moines, Ankeny, Urbandale, Altoona, Johnston, and Clive, so most homeowners already have a gas meter and just need a line run to the fireplace location. In a handful of more rural pockets toward the edges of the county—around Elkhart, Alleman, or Mitchellville—propane is the more practical option. Nearly every gas fireplace on the market today can be configured for either fuel; your installer sets the correct orifice and regulator based on what's available at your address.

Most modern direct-vent gas fireplaces will, as long as they use an IPI (intermittent pilot ignition) system with battery backup—typically a set of AA batteries built into the unit that take over automatically when the power drops. Polk County sees occasional winter ice storms and thunderstorm-driven outages that can knock out power for hours, so this matters more than it might seem. Valor fireplaces handle it differently: their pilot generates its own electricity through the thermocouple, so there are no batteries to remember at all. Ask your local dealer which ignition system is on any unit you're considering.

A gas fireplace is a fully built-in unit installed into a framed wall opening—common in new construction and remodels throughout Ankeny, Waukee-adjacent Polk County, and West Des Moines. A gas insert slides into an existing masonry firebox, which is the more typical situation in older Des Moines and Urbandale homes with an underused wood-style fireplace. A gas stove is a freestanding cabinet-style unit that sits out in the room and vents through a wall or existing flue—a good fit for smaller homes or rooms without an existing fireplace opening. For most Polk County homeowners upgrading an existing fireplace, an insert is the simplest and most cost-effective path.

Yes. Each city in Polk County issues its own building and gas permits—Des Moines, West Des Moines, Ankeny, Urbandale, and the rest each run their own permitting process, and unincorporated areas fall under the Polk County building department. Gas line work specifically requires a licensed gas-fitter, which is one reason working with an established hearth dealer is worth it: they coordinate the gas line, venting, and inspection sign-off as one job instead of you managing separate trades.

Vented (direct-vent or B-vent) gas fireplaces pull combustion air from outside and exhaust combustion byproducts back outside through a sealed vent—the standard, code-compliant choice in every state. Vent-free units burn directly into the room without exterior venting; they're legal in Iowa but come with strict room-size minimums, oxygen depletion sensors, and ventilation requirements. Given how many Polk County homes are on open floor plans with forced-air furnaces already handling background heat, direct-vent units are by far the more common and more recommended choice locally—better indoor air quality with no compromises.

Plan on an annual inspection, ideally before the first cold snap in late fall. A certified technician checks the burner, pilot assembly, venting, and gas connections, and cleans the glass and interior. This is quick compared to wood chimney sweeping, but it's what keeps the unit safe and efficient through a Polk County winter. Local gas appliance service providers typically charge $150 to $250 for the visit.

Wood is genuinely uncommon as a new install in Polk County—there's no public timber land nearby and most homes are on tight suburban lots, so it's not a fuel path most local dealers push, though older masonry fireboxes do exist. Gas is the default for real heat output: instant on-off control, no ash or soot, and reliable performance through a winter with lows regularly in the teens. Electric fireplaces and inserts fill a different niche—condos, apartments, rentals in the Des Moines urban core, or rooms where running gas line or venting isn't practical—offering ambiance and mild supplemental warmth without any venting requirement at all. For most single-family homes across Ankeny, Urbandale, West Des Moines, and Des Moines proper, gas remains the primary recommendation.

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.

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.

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.
