Warmth That Doesn't Depend on the Texas Grid.

Most gas fireplace and insert installations in the Granbury area run $3,500 to $8,500, depending on the unit, the venting path, and whether propane line work or a new tank setup is needed. Because most homes here run on propane rather than municipal natural gas, factor in an additional $500 to $1,500 if you don't already have a propane tank sized for a fireplace—your local propane supplier can advise on tank size and delivery scheduling. A direct-vent insert going into an existing masonry fireplace with propane already plumbed to the house is typically on the lower end; new construction or a fireplace added to a room with no existing gas service runs higher.

Propane is the standard fuel for the vast majority of gas fireplace installations in Granbury and Hood County. There's no citywide natural gas main serving most of the area—the local utilities (Oncor, Texas-New Mexico Power, United Electric Cooperative) deliver electricity, not gas—so homes here typically run on a propane tank, either buried, above-ground, or a smaller cylinder for lower-demand units. Nearly every gas fireplace model on the market can be configured for propane with the correct orifice and regulator, so fuel type shouldn't limit your options. Your local dealer will coordinate the tank sizing and setup with a propane supplier as part of the install.

It depends on the ignition system, and this matters more in Granbury than in most places given the 2021 Winter Storm Uri outages that left parts of Hood County without power for days during a hard freeze. Standing-pilot gas fireplaces will light and run with zero electricity. Units with intermittent pilot ignition (IPI) typically include a battery backup that keeps them functional during an outage, as long as the batteries are fresh. Valor's gas fireplaces take it a step further—the pilot's thermocouple generates the small amount of electricity the unit needs, so there's no battery to remember at all. If grid-independent backup heat is a priority for your Granbury home, ask your local dealer specifically about the ignition system before you buy.

A gas fireplace is a built-in unit framed into a wall—the right choice for new construction or a room without an existing fireplace. A gas insert slides into an existing masonry firebox and uses the chimney as its vent path, which is common in older Granbury neighborhoods with existing wood-burning fireplaces that homeowners want to convert. A gas stove is a freestanding cabinet-style unit that sits on the floor, often chosen for lake houses or additions where a full fireplace surround isn't practical. All three can run on propane in this market.

Yes. Whether your home falls under the City of Granbury's building department or unincorporated Hood County's permitting office, a new gas appliance installation requires a building permit, and the propane or gas line work needs to be done by a licensed installer. Most hearth dealers serving the Granbury and Lake Granbury area handle the permit application and inspection scheduling as part of the job, so you're not coordinating separate trades yourself.

Vented (direct-vent) gas fireplaces draw combustion air from outside and exhaust it back outside through a sealed pipe—they're the most common choice and produce real, substantial heat. Vent-free units burn fuel directly into the living space without external venting; they're legal in Texas but come with strict room-size and ventilation requirements, and they're generally better suited to supplemental or ambiance use than as a primary heat source. For a lake house that sits closed up for stretches of time, or a primary residence where indoor air quality matters, direct-vent is usually the safer, more universally recommended option. Ask your local dealer to walk through both if you're weighing a smaller secondary space.

Plan on an annual inspection, ideally before the first cold snap each fall. A technician checks the burner, pilot assembly, gas connections, and venting, and cleans the glass and interior—this typically runs $150 to $300 in the Granbury area. It's a shorter, less involved visit than a wood-stove chimney sweep, but skipping it is how small issues (a dirty pilot, a failing thermocouple) turn into a fireplace that won't light on the one cold night you actually need it.

For most Granbury homes, gas is the more practical choice. Wood heat isn't really part of the local climate story—with an average winter low around 31°F and a mild, short heating season, a wood stove is more heating capacity than most homes need, and it's uncommon to see one installed here as a primary source. Oak, pecan, and mesquite are all available regionally, but locally they're firewood for smokers and fire pits more than for hearth heating. A propane-fed gas fireplace gives you real, on-demand warmth for the occasional hard freeze—including grid-outage scenarios like Winter Storm Uri—without the upkeep, ash, or storage that comes with burning wood.

It depends on whether you're heating a full-time residence or a Lake Granbury weekend property, and how open the floor plan is. A smaller direct-vent unit (20,000–30,000 BTU) is plenty for supplemental heat in a den or lake cabin given the area's mild winters. A larger unit (30,000–40,000+ BTU) makes more sense as a focal-point fireplace in an open living area of a primary home. Because most installations here run on propane, tank size and delivery capacity should factor into the decision too—a local dealer can size both the fireplace and the propane setup together during an in-home consultation.

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.

For an average home—covering the fireplace, the vent pipe, and basic installation—a budget between $3,900 and $5,500 gives you a lot of options across wood, gas, and pellet. By the time you add finish work, gas line, and electrical, the average complete installation lands between $5,000 and $12,000 all-in. In a remodel or new build, a good rule is to put about 2.5% of the total project cost toward the fireplace.
