Reliable Warmth for Melissa, Texas—No Matter What ERCOT Does.

Most gas fireplace installations in Melissa run $3,500 to $8,500, depending on the unit and whether a gas line is already stubbed to the room. Because most homes here are slab-on-grade with no basement, running new gas line to a room that doesn't already have one—say, a primary bedroom or a converted study—adds cost compared to a home with an accessible crawlspace or attic run. Builder-installed units in newer Melissa subdivisions are often mid-grade B-vent fireplaces that can be upgraded to a nicer direct-vent unit for less than a full new installation would cost. A local retailer will quote a firm number after seeing your gas line access and venting path.

If your home has an older masonry wood-burning fireplace—more common in Melissa's original townsite than in the newer subdivisions—a gas insert can usually be fitted into the existing firebox using the chimney as a vent chase, typically for $4,000 to $7,000. Most homes built in the last two decades, though, already have a gas log set or B-vent fireplace from the builder, which is a simpler and cheaper upgrade to a full direct-vent gas insert since the gas line is already in place. Either way, a local installer will confirm what's already run to the room before quoting the job.

Either works, and most gas fireplace models can be configured for one or the other. Inside the city of Melissa, natural gas service reaches the large majority of homes, so if your range or water heater already runs on gas, adding a fireplace is straightforward. In some of the newer developments on the edges of town and in unincorporated Collin County, gas lines haven't caught up with construction yet, and propane—supplied by a tank on the property—is the standard workaround until service arrives. Your installer will set the correct orifice and regulator for whichever fuel you have.

It depends on the ignition system, and this matters more in Melissa than it used to. During Winter Storm Uri in February 2021, ERCOT rolling blackouts left parts of Collin County without power for days during subfreezing temperatures. Gas fireplaces with a standing pilot light will operate with zero electricity—you can light them by hand and they'll keep running. Units with IPI (intermittent pilot ignition) need a small amount of power, usually from AA batteries built into the unit, to fire the igniter, but they'll still work through a grid outage as long as the batteries are fresh. Valor fireplaces go a step further—their pilot assembly generates its own electricity through the thermocouple, so there's no battery to forget. If outage-proof heat matters to you, ask your local dealer specifically about the ignition system before you buy.

A gas fireplace is a fully built-in, framed unit—the standard choice for new construction, which describes most homes in Melissa. A gas insert is built to slide into an existing masonry firebox, which matters more for the handful of older homes near the original townsite. A gas stove is a freestanding unit that sits out in the room on its own base and vents through a wall or ceiling, useful in rooms without any existing fireplace opening, like a converted garage or bonus room. For most Melissa homeowners working from a builder-grade fireplace shell, upgrading to a better direct-vent fireplace insert is the most common path.

Yes—the City of Melissa Building Department requires a permit for gas fireplace installations, and any new or modified gas line needs a licensed gas-fitter regardless of jurisdiction. Homes outside city limits in unincorporated Collin County go through the county's permitting process instead. Most hearth retailers handle the permit application and inspection scheduling as part of the installation, so you generally don't have to coordinate it yourself.

Vented (direct-vent) gas fireplaces pull combustion air from outside and exhaust it back outside through a sealed pipe—they're the cleanest and most universally recommended option. Vent-free gas units burn directly into the room air with no external venting; they're legal in Texas, unlike in states such as California and Colorado, but they come with strict room-size and ventilation requirements and release some water vapor and combustion byproducts into the living space. In a well-insulated newer Melissa home, that added humidity is worth thinking through with your dealer before choosing a vent-free unit over a direct-vent one.

Plan on an annual inspection, ideally in early fall before the first cold snap. A certified technician checks the burner, pilot assembly, gas connections, and venting, and cleans the glass and firebox. This runs $125 to $200 in the Melissa area and is worth doing every year even though gas units don't need chimney sweeping the way wood stoves do—a neglected pilot or igniter is the most common reason a fireplace won't fire on the one cold night you actually need it.

For most Melissa homeowners, no—wood-burning fireplaces are uncommon here. With only 2,429 heating degree days a year and mild winter lows around 34 degrees, there's little practical need for a high-output wood-heat source, and many of the newer subdivisions have HOA covenants that discourage or restrict wood smoke outright. A small number of homeowners on larger lots still install wood-burning fireplaces for the authentic experience, burning local oak, pecan, or mesquite, but it's the exception rather than the rule. Gas remains the practical choice for both everyday ambiance and the occasional hard freeze.

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 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.

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.

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.
