Heat that holds through a Door County winter.

It depends on whether you're heating a year-round home or a seasonal cottage, and where you sit on the peninsula. Wood is the traditional choice inland—oak and maple burn long and hot, birch lights fast, and aspen works well as kindling or shoulder-season fuel; a lot of Door County wood is cut from local land or the orchards that ring the peninsula. Gas is the convenience fuel, but natural gas service is really only reliable in and around Sturgeon Bay—most of the peninsula, including Sister Bay, Ephraim, and Washington Island, runs gas appliances on propane instead. Pellet stoves are a strong fit for anyone who wants wood-style heat without stacking a woodpile, and regional supply from Indeck Energy Services and Lignetics keeps pellets easy to find. Electric fireplaces are common in seasonal cottages and condos where an owner wants ambiance and supplemental heat without adding venting to a building they only occupy part of the year. Most year-round Door County homes end up with wood or propane as primary heat and electric or pellet in a secondary room.

In most cases, yes. New wood stoves, wood inserts, gas fireplaces, gas inserts, gas stoves, and pellet stoves typically require a building permit through Door County's Land Use Services office, or through the City of Sturgeon Bay's building inspector if you're within city limits. Gas installations also need a separate permit for the gas line and a licensed propane or gas fitter to make the connection, since so much of the peninsula runs on propane rather than piped natural gas. Wood appliances sold and installed today need to meet current EPA 2020 NSPS emissions standards. Electric fireplaces generally skip the permit process unless you're doing a built-in installation that involves hardwiring or a new circuit. Most local hearth retailers handle the paperwork as part of the installation, so it's rarely something you have to manage yourself.

No—Door County has no air quality non-attainment designation and no history of burn advisories. That's largely a function of geography: the peninsula sits between Green Bay and Lake Michigan, and the wind off both bodies of water keeps air moving through winter rather than trapping smoke the way an enclosed inland basin can. That doesn't mean there are no rules—any new wood stove or insert sold and installed still needs to meet EPA 2020 NSPS emissions standards, and a well-seasoned load of local oak or maple will always burn cleaner than green wood regardless of local air quality status. But if you're moving here from a place with mandatory curtailment days, Door County simply doesn't have that layer of restriction.

Many hearth retailers based near Sturgeon Bay carry three or four fuel types, since they're serving a mix of year-round homes and seasonal cottages with very different needs—a full-time resident inland might want a wood insert, while a Sister Bay condo owner wants a plug-in electric unit for weekend visits. Dealers that stock wood, gas, pellet, and electric let you compare options side by side, which matters if you're not yet sure whether you want a propane-fed gas fireplace or a pellet stove for a place you visit part-time. Smaller retailers may specialize—some focus mainly on wood and pellet installs for year-round homes, others lean into electric and gas for the vacation-property market. Ask directly which fuels a dealer installs and services before assuming.

Service logistics on the peninsula depend heavily on whether a home is occupied year-round or seasonally. For seasonal cottages in Fish Creek, Ephraim, or Egg Harbor, most owners schedule chimney sweeps and gas inspections in spring, before the summer tourist season fills local technicians' calendars, or in early fall before the first cold snap. For Washington Island, technicians typically bundle service calls into a single ferry trip, so booking a bit further ahead—and expecting a modest ferry-related travel fee—helps. If you're only at your cottage part of the year, it's worth asking your technician about a pre-season check tied to your travel schedule rather than waiting for a mid-winter problem you're not there to notice.

Ranges vary by fuel and by how remote the property is. Wood stove or insert installation: roughly $4,000–$8,500 for a typical install, up to $12,000 for new chimney construction. Gas fireplace, insert, or stove: roughly $4,000–$10,000, with propane tank setup or line work pushing toward the higher end for homes without existing service. Pellet stove or insert: roughly $4,000–$7,000 for most installs. Electric fireplace: $200–$3,000 for the unit itself, plus $400–$1,200 in labor for anything beyond a simple plug-in. Homes on Washington Island or other harder-to-reach parts of the peninsula should expect modest travel or ferry-related surcharges on top of these ranges.

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.

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.

It's a visit where a hearth professional measures your space, confirms the model you picked actually works in your home, and walks the specs—framing, gas line, venting, finish work—before anything is ordered. Some details you just can't know until you see the house. Never make a down payment without one; it's the single most-skipped step that burns buyers.

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.
