Heating through 8,140 heating degree days in Johnson County.

It depends on the home and how remote it is. Wood is the backbone fuel for most rural Johnson County properties—lodgepole pine and ponderosa cut under a Bighorn National Forest permit keep fuel costs low, and a catalytic stove will hold a fire through an overnight low near zero the way homes in Bozeman, MT rely on wood heat through similar stretches. Gas is mostly propane here rather than piped natural gas, since municipal gas service is limited outside Buffalo—propane fireplaces and inserts give instant heat without hauling wood, which matters for older residents or second homes. Pellet is a solid middle ground if you want wood-style heat without splitting and stacking; Bear Mountain, Lignetics, and Forest Energy all distribute in the region. Electric works well as supplemental heat in a bedroom or den but won't carry a home through Johnson County's coldest stretches on its own. Many ranch households run wood or pellet as primary heat with propane or electric backup for convenience and power-outage gaps.

Generally yes for wood, gas, and pellet appliances. New wood stoves and inserts need to meet current EPA emissions standards, and a building permit covers the installation and any chimney or hearth pad work. Gas fireplaces, inserts, and stoves typically require both a building permit and a licensed installer for the propane line connection, since most of the county runs on propane rather than piped gas. Electric fireplaces usually skip the permit process unless you're doing a built-in installation with new wiring. In Buffalo, permits go through the town; outside town limits, unincorporated Johnson County properties typically fall under county building requirements—a local retailer can tell you which applies to your address, and most handle the paperwork as part of the installation.

There's no routine winter air-quality advisory program here the way there is in inversion-prone basins elsewhere in the Rockies—Johnson County's main air quality concern is wildfire smoke in late summer and early fall, tied to conditions in the Bighorn National Forest and surrounding areas. That smoke is seasonal and unrelated to home heating, but it's worth knowing if you're planning outdoor burning or firewood cutting trips near fire season. For home heating, the practical restriction is on the front end: new wood stove installations need to be EPA-certified units, which is standard across the country now and something any local retailer will already have covered in what they sell.

In a county this size, most retailers carry two or three fuel types rather than a full four-fuel lineup—the customer base doesn't support the kind of large multi-fuel showroom you'd find in a bigger market. Wood and pellet are commonly stocked together since both appeal to the same rural, self-sufficient customer. Propane/gas units are often available through the same dealer or through a local propane supplier that also handles fireplace hookups. Electric fireplaces are the easiest to add to any lineup since they don't require venting, so even a smaller dealer may carry a few models. If you're comparing fuels, ask the Buffalo-area retailers directly which lines they carry—with a small dealer base, a phone call upfront saves a drive.

Most technicians covering Johnson County are based in or near Buffalo and drive out to Kaycee, the I-25 corridor, and ranch properties along forest access roads. Expect a modest trip fee for anything beyond a short drive, and plan on booking annual service in late summer or early fall—appointments get harder to land once temperatures drop and everyone's stove or furnace needs attention at once. If you're on a road that closes or gets difficult in heavy snow, it's worth scheduling your chimney sweep or gas inspection well before the first real cold snap, since a mid-January service call may mean waiting out weather before a tech can get to you.

Wood stove or insert installation: roughly $4,500–$9,500 for a typical install, running higher for new chimney construction on a ranch home without existing masonry. Propane fireplace, insert, or stove: roughly $4,500–$10,500, with cost driven mainly by whether a propane line already reaches the install location. Pellet stove or insert: roughly $4,500–$7,500 for a standard install. Electric fireplace: $200–$3,000 for the unit itself, plus $400–$1,200 in labor for anything beyond a simple plug-in installation. Rural properties may see costs on the higher end of these ranges due to travel time and, in some cases, more complex venting through log or timber-frame construction.

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.

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.

Five come up constantly: budgeting for the unit but not the full job (vent, gas line, electrical, finish work); drowning in options instead of starting from style and fuel; buying without an in-home preview; handing installation to a handyman instead of a pro; and giving up out of sheer indecision. Every one is avoidable with a clear plan—step one, step two, step three.
