Can You Convert a Wood Fireplace to Gas?
Don’t get us wrong, wood-burning fireplaces are great - to a certain extent. They have an amazing ambiance, as there’s nothing quite like the crackling of burning firewood. But they’re a hassle to manage and maintain. They don’t burn that clean, either.
The good news is you can easily convert any working masonry or factory-built wood-burning fireplace with an intact chimney into a gas fireplace. In fact, it’s easy and cost-effective since the firebox and chimney are the expensive parts of a fireplace.
Different Ways to Convert a Fireplace to Gas
Three paths laid out in front of you, and the right one comes down to:
- Your budget
- The end result you’re going for
Gas Log Sets (Simplest Option)
The easiest way to convert a wood fireplace to gas is by plopping log sets where the wood used to burn. Ceramic or refractory logs sit on a burner that drops onto your existing grate.
You don’t have to deal with any sort of sealed combustion chamber - just let the fire burn in the open like your wood used to. You can get some really realistic-looking logs, but the trade-off is efficiency. An open burner is just going to send most of the heat up the chimney. Super wasteful.
Still, these have their place if your only goal is to keep the ambiance of your wood-burning fireplace and you don’t care about supplemental heat. Also the cheapest way to go about it. Get the best gas fireplace insert at The Great Fire Company!
Gas Fireplace Inserts (Better Efficiency)
These sealed fireboxes slide right into your existing fireplace opening to take care of both combustion and venting. Your old firebox is basically just a shell that holds the new insert.
Most inserts are direct vent, which just means they pull outside air for combustion and exhaust through a liner that runs up your chimney. There are vent-free alternatives if you want to skip the liner, but they’re not always allowed. Some jurisdictions restrict them, so double-check your local building codes before buying anything.
Built-in Gas Fireplaces (Most Involved)
A built-in gas fireplace is undoubtedly the most expensive and complicated way to convert a wood-burning fireplace to gas. But there’s a reason so many homeowners bite the bullet and go this route.
You take the old firebox out and place a new one into the framed opening, complete with its own vent system. The appeal here is customization, as you’re not limited to finding something that fits the old firebox. You can jump from a 30” traditional opening to a 60” linear style. Just expect to shell out quite the cash for all the labor that goes into this.
How Much Does it Cost to Convert Fireplace to Gas?
So, how much does it cost to convert fireplace to gas? Let’s break it down by conversion method:
- Gas log sets: $300 to $1,200 for the unit itself. Simpler and more affordable if you already have a gas line in place. Total with labor is $500 to $2,500.
- Gas fireplace inserts: Our entry-level units are around $1,899, but you have to factor in professional installation and a chimney liner for direct vent models. Expect to spend between $2,500 to $5,500 all in.
- Built-in gas fireplaces: Our built-in gas fireplaces start at $1,489 and go past $10,000 for large linear and see-through models. Installation is expensive. You may need a new gas line on top of framing and surround work. Budget for between $8,000 and $12,000.
It’s not cheap, but it’s a project worth undertaking if you’re looking to sell your home or just want to enjoy your living area more.
Factors That Influence the Cost to Convert Wood-Burning Fireplace to Gas
The first factor at play is whether or not you can use an existing gas line. You save between $500 and $2,000 in line work if you already have a gas stub to connect to. Running a new line from the meter can run between $15-$25 per linear foot! Most runs are 20 to 60 feet, so that's $300 to $1,500 just for the pipe.
Your fuel type matters as well for the initial installation cost. The connection is simpler for a natural gas fireplace (assuming your home already has gas service). Choosing to go with a propane fireplace setup requires a tank and a regulator at the connection point.
We touched on venting already, but adding a chimney liner will cost another $400 to $1,200, depending on chimney height. You can skip this with a ventless model, but those aren’t always a viable option.
Then there’s the stuff you may not have even thought of yet, like permits. Those are another $50 to $400. Some municipalities require a gas permit and a separate building permit. Messing up on the permitting side of things could void your homeowner’s insurance, so don’t overlook this step.
The biggest line item is going to the fireplace itself. Our inserts range from $1,899 to $3,889. Built-in fireplaces start at $1,489, and large linear models run well past $10,000. Remember, though, you’re getting the lowest price on the best model, guaranteed, when you shop at The Great Fire Company!
How to Convert a Fireplace to Gas: Step-by-Step Guide
This isn’t a weekend DIY project by any stretch of the imagination. You should expect to contract out portions, from the gas line to the framing work. Here’s an overview of the project.
Get an Inspection and Figure Out Permits First
Like we just touched on, you need to do your due diligence on the compliance side. Have a chimney tech inspect the firebox and flue before you buy anything. They'll check for structural damage and make sure clearances are within code.
This is also a good time to get your chimney cleaned if you haven’t done that recently. You have to remove years of creosote buildup before any new equipment goes in.
Call your local building department to figure out permit requirements. Most jurisdictions need at least a gas permit. Some require a building permit, too. Get this dialed in before the installer shows up.
Installing a Gas Line (If You Don’t Already Have One)
You might get away with skipping this step if you have a gas line nearby already. Otherwise, you’ll need a licensed plumber or gas fitter to run the line from your main supply to the fireplace.
Cost depends on distance and whether the run goes through finished walls or crawl spaces. Budget $300 to $2,000. For propane fireplaces, the installer connects to your tank with a properly sized regulator. Your propane supplier can help size the tank for your unit's BTU.
Installing Your Gas Fireplace Insert/Log Set
The installer positions the unit and connects the gas supply. A liner goes up the chimney if you're going with a direct vent model. A gas log set could take just a few hours. An insert with a chimney liner is a full-day job.
Enjoy the Vibe!
At this point it’s just a matter of testing for gas leaks and confirming the ignition is ready to be used, which your installer should do on your behalf before leaving. Then, you hit a switch and enjoy the fire.
Should You Consider Converting to an Electric Fireplace Instead?
We know you came here curious about the cost to convert fireplace to gas, but hear us out. An electric fireplace could be a better fit if running a gas line is a dealbreaker. These plug into your typical 120V outlet and don’t need any venting or gas line work. You probably don’t even need a permit! The electric fireplace installation cost can be under $1,000.
You just won’t get the same exact ambiance or heat output with an electric fireplace. But, we encourage you to read through our gas vs electric fireplace comparison and then make your own decision!
Bottom Line on the Cost to Convert Fireplace to Gas
In closing, how much does it cost to convert a fireplace to gas? Anywhere from $2,500 to $5,500 for the full project. More if you decide to tear out the old firebox and build a new one, but that’s more work than it’s worth for a lot of homeowners.
We carry the fireplace units you need to make the conversion happen, always at the lowest prices online - guaranteed. Our experts are available for you from A to Z, whether you want help setting expectations on cost or navigating the installation process. Get in touch today!
