Plenty of homeowners love the idea of a fire but not the work that comes with wood: hauling logs, building and tending the flame, cleaning ash, and keeping up with sweeping and creosote. Converting a wood-burning fireplace to gas solves all of that, trading the ritual for push-button convenience and, in most cases, far better heat. It is one of the more popular fireplace projects we handle. Here is what your options are, what it costs, and the one technical detail that makes or breaks a safe conversion. For the wider decision, see our gas vs wood comparison.
Can You Convert a Wood Fireplace to Gas?
In almost all cases, yes. A standard masonry wood-burning fireplace is a good candidate for conversion to gas, and there are three common ways to do it, ranging from a simple ambiance upgrade to a full efficient-heat conversion. The right choice depends on what you want out of the fireplace and the condition of your chimney. Every option requires a gas supply to the fireplace, and the flue needs to be evaluated before work begins, since venting is where a conversion most often goes wrong.
Your Three Conversion Options
Gas Log Set
The simplest and cheapest conversion. A set of realistic ceramic gas logs is installed in the existing open firebox and connected to a gas line, and it burns with the damper open, venting up the existing flue much like a wood fire. A vented gas log set is mostly about ambiance rather than heat, since the open flue lets most of the warmth escape. It is the right choice if you want the look of a fire with none of the wood work and do not need the fireplace to heat the room.
Gas Insert
The efficient-heat option. A sealed gas insert is fitted into the fireplace opening and vents through a stainless steel liner run up the chimney, usually in a sealed direct-vent style. Because it is sealed and does not lose heat up an open flue, an insert delivers real, efficient warmth, often up to 90 percent efficiency. This is the choice for homeowners who want the fireplace to actually heat the room, and it is the most common full conversion we install.
Built-In Gas Fireplace
In some cases the old firebox is removed and a new built-in gas unit is installed. This is more involved and more expensive, and it usually only makes sense when the existing masonry is failing or you want to change the fireplace substantially. For most conversions, a log set or an insert is the simpler path.
What a Conversion Costs
Cost tracks the option you choose. A basic vented gas log set runs roughly $500 to $2,500 installed. A gas insert, which includes the unit, the liner and the connection, typically runs $3,000 to $7,000 and delivers the efficiency to match. If a gas line does not already reach the fireplace, running one adds to either project, and the distance and access determine how much. As with any fireplace work, the venting is the variable that most affects the total, which is why an inspection comes first. See our fireplace installation cost guide for the full picture.
The Liner: The Detail That Matters Most
Here is the technical heart of a gas conversion. A gas insert almost always requires a stainless steel liner sized to the unit and run the full height of the chimney. There are two reasons. First, gas combustion produces acidic byproducts and moisture that corrode an unlined or oversized masonry flue over time. Second, an insert is small and efficient, and venting it into a large old flue lets the exhaust cool and stall, causing poor draft and, potentially, a carbon monoxide hazard. A correctly sized liner keeps the exhaust warm, moving and contained. If a conversion quote for an insert leaves out the liner, that is a red flag.
The Conversion Process
- Inspection. We start with a chimney inspection, including a camera scan, to confirm the flue's condition and size and to catch any repair needed before conversion.
- Gas supply. We confirm or arrange a gas line to the fireplace, done by a licensed professional.
- Unit and liner. The log set or insert is installed, and for an insert the correctly sized liner is run and connected.
- Testing. We test the gas connection, confirm the unit lights and drafts correctly, and check for leaks.
- Documentation. You get a written record of the work and guidance on the simple annual maintenance a gas fireplace needs.
Life After Conversion: Easier, But Not Maintenance-Free
The big payoff of converting to gas is how little the fireplace now asks of you. No wood to buy or haul, no ash to clean, no creosote, and no annual sweeping. But gas is not maintenance-free: the chimney or vent still needs an annual inspection, because gas byproducts corrode the liner over time and a blocked or cracked flue is a carbon monoxide risk. That yearly check is far less involved than maintaining a wood fireplace, but it is not optional. Our guide on maintenance by fuel type explains what changes when you switch.
Can You Convert Gas Back to Wood?
It is possible but less common, and more involved than going the other way. Reverting to wood means removing the gas components and confirming the flue is properly lined and sized for wood-burning, which produces more heat and creosote than gas. If you think you might want the option of a real wood fire later, keep that in mind when planning, and mention it during the inspection so the flue can be evaluated for both uses.
Is a Gas Conversion Right for You?
A conversion makes the most sense for a specific kind of homeowner: someone who has an existing wood-burning fireplace, enjoys having a fire, but has grown tired of the work, the mess, or the maintenance that wood requires. If you find yourself lighting fewer fires because hauling wood and cleaning ash is a chore, a conversion often brings the fireplace back into regular use. It also suits homeowners who want more reliable heat than an open wood fire provides, since a gas insert delivers efficient warmth on demand. On the other hand, if the ritual and sensory experience of a real wood fire is exactly what you love, a conversion trades that away, and you may be happier keeping wood and simply improving its efficiency with an insert instead. There is no wrong answer, only the one that fits how you actually use the fireplace.
What to Expect After the Switch
Homeowners are often surprised by how much easier life becomes after converting to gas. A fire is a matter of a switch or a remote, there is no wood to store or buy, no ash to shovel, and no creosote to worry about. The one adjustment is remembering that the chimney or vent still needs its annual inspection, even though it no longer needs sweeping. Most people find the trade well worth it, which is why gas conversions remain one of the most common and satisfying fireplace projects we handle.
The Bottom Line
Converting a wood fireplace to gas is a popular, practical upgrade: choose a gas log set for simple ambiance or a gas insert for real, efficient heat. The critical detail is the liner, which a proper insert conversion always includes, and the essential first step is a chimney inspection.
