Convert Fireplace to Gas: 2025 Cost, Option & Kits Explained
If you're tired of stacking wood, cleaning ash, and waiting forever for your living room to warm up, you're not alone. More and more homeowners are converting their traditional wood-burning fireplaces to gas, and for good reason.
Gas fireplaces offer instant heat, cleaner operation, and a sleek, modern look without losing the cozy ambiance you love. But what does it take to make the switch?
In this guide, we’ll break down everything you need to know about converting your fireplace to gas, from the types of gas systems available to the installation process and costs involved.
Can You Convert Your Fireplace to Gas?
The short answer is: yes, in most cases. But the type of fireplace you currently have plays a big role in determining your options. You should also understand how a wood fireplace works before going about this process.
If you have a masonry fireplace made of brick or stone with a working chimney, you’re in the best position for a gas conversion. These structures are ideal for either gas inserts or gas log sets.
Prefabricated fireplaces (also called zero-clearance units) can also be converted in many cases, but you’ll need to verify compatibility with the manufacturer and local building codes.
Before doing anything, bring in a certified fireplace professional. They'll assess whether your current setup is safe for gas and recommend the right path forward.
Conversion Options: Gas Insert vs Log Set vs Built-In
When converting your fireplace to gas, you have three main options, and each serves a different purpose:
Gas Fireplace Inserts
Gas fireplace inserts are sealed systems that slide into your existing firebox. They’re the most efficient option, capable of heating a room while maintaining a realistic flame look. Great for those wanting warmth and style.
Gas Log Sets
Gas log sets are more about ambiance. They sit openly inside your firebox and produce a beautiful flame, but they’re not very efficient for heating. If you just want aesthetics without much heat output, this is a simple, lower-cost option.
Built-In Gas Fireplaces
Built-in gas fireplaces are often chosen when doing a full remodel. These units are installed into a framed wall and don't require an existing fireplace. They're ideal if you're starting from scratch or replacing a poorly functioning unit.
And while gas is the most common upgrade, don’t overlook electric options, especially if you live in an apartment or a home without a gas line. We’ll compare those later in the article.
Gas Fireplace Conversion Kits: What Do They Include?
If you’ve been looking into how to convert your fireplace to gas, chances are you’ve come across gas fireplace conversion kits.
These kits are designed to provide the essential components needed for the upgrade, usually including a burner system, gas valve, pilot light or ignition, decorative gas logs, and the necessary connection hardware. Some even come with remote controls or built-in thermostats for added convenience.
However, despite how straightforward they may seem, these kits aren’t made for DIY installs. Working with gas lines is serious business. Improper installation can lead to gas leaks, carbon monoxide risks, and even void your warranty.
That’s why manufacturers and safety codes strongly recommend and often require that a certified technician handle the setup. So while a gas conversion kit might be marketed as a simple solution, the safest and smartest route is hiring a pro.
This is especially important to avoid mishaps when trying to turn on your gas fireplace in the future.
Step-by-Step Overview of the Conversion Process
Converting a wood-burning fireplace to gas isn’t a weekend project. Here’s what the process typically looks like when handled by a pro:
1. Initial inspection: A technician will assess the condition of your existing firebox and chimney, ensuring it’s safe and compatible with gas components.
2. Gas line installation: If you don’t already have one, a gas line will need to be run to your fireplace. This often involves cutting through walls or floors, so it’s not something to tackle without experience.
3. Install the insert or log set: Depending on your choice, the technician will place the gas insert or log set into your firebox, connect it to the gas line, and ensure everything is sealed and properly aligned.
4. Venting and safety check: Gas inserts require proper venting (usually through your chimney), while ventless models have stricter requirements. The installer will run full safety diagnostics, including carbon monoxide checks and leak testing.
To get this done right, search for “fireplace conversion to gas near me” and choose a licensed contractor who’s familiar with your local codes. They’ll also handle permitting, which is required in most jurisdictions.
Cost to Convert Fireplace to Gas: What to Expect
The convert fireplace to gas cost can range widely depending on the type of system you choose, the condition of your current setup, and whether a gas line already exists. On average, most homeowners spend between $2,000 and $5,000 for a complete conversion.
A basic gas log set will fall on the lower end of that range, while a high-efficiency gas fireplace insert, complete with new venting and a custom surround, can push the cost higher.
Labor costs, gas line installation, chimney modifications, and permits all add to the final price tag. If your home doesn’t already have a gas line in place near the fireplace, that alone could add several hundred to over a thousand dollars to the total.
It’s also worth asking about available rebates or energy efficiency incentives in your area, which can help offset the upfront investment.
Is Gas Better Than Electric?
It depends on your goals. Gas fireplaces offer a real flame, strong heat output, and ambiance that’s hard to beat. If you’re looking to heat a room efficiently while maintaining the look and feel of a traditional fire, gas is the clear winner. However, electric fireplaces are becoming increasingly popular for their simplicity and low-maintenance setup.
Unlike gas, electric fireplace units don’t require venting, which makes them easier to install, especially in condos or apartments where running a gas line might not be an option, or if you’re looking to convert a fireplace to electric instead.
They’re also safer in homes with small children or pets since there’s no real flame. On the flip side, electric fireplaces typically provide less heat and a less realistic flame compared to gas.
If you're weighing both options, consider how often you use your fireplace, what kind of ambiance you want, and what’s feasible in your home. Sometimes, the choice between gas and electric comes down to budget and logistics as much as personal preference.
Safety, Permits & Local Codes
When you convert your fireplace to gas, safety isn’t just a box to check. It’s the foundation of the entire project. A professional installation ensures that gas lines are securely connected, venting is properly configured, and the system passes all safety checks.
One of the biggest risks with improper installation is carbon monoxide buildup, which is why certified technicians always perform leak testing and ventilation assessments before signing off on the job.
You’ll also need to secure the right permits. Most municipalities require approval before any gas line work can begin, and inspections are typically required once the installation is complete. Working with a licensed contractor makes this process much smoother.

Final Tips Before You Convert Your Fireplace To Gas
Before you greenlight the project to convert your fireplace to gas, take a few steps to make sure you're setting yourself up for long-term satisfaction. First, schedule a chimney inspection and cleaning especially if it's been a while.
Even with a gas system, you don’t want to overlook venting safety. Next, talk to your installer about venting compatibility (see our full guide on vented vs ventless fireplaces) especially if you’re leaning toward a direct-vent or ventless system
Choosing a quality insert or log set from a reputable brand will make a big difference in both performance and appearance. And finally, ask about ongoing maintenance. While gas systems are lower maintenance than wood, annual checkups are still a good idea to keep things running smoothly. A little planning now can save you time, money, and stress down the line.
