Gas Fireplace Costs: A Guide for Homeowners

Gas fireplace pricing guide

A gas fireplace is a great alternative to the traditional fireplace during the cold season. Not only does a gas fireplace make a great supplemental heat source during the winter months, it  provides a warm ambiance without all the mess and upkeep of a wood-burning fireplace.

In this guide, we explore the costs of gas fireplaces, from installation to running costs for the different types of gas fireplaces. We also discuss the costs of add-ons like gas log sets and decorative accessories.

Gas Fireplace Cost

Depending on how advanced of a system you need, gas fireplaces range in cost from $400 (firebox only) to upwards of $3,000 (direct vent fireplace system). If you’re looking for just a firebox, expect to pay $400 all the way up to $1,200. 

Typically, the larger and more featured fireboxes cost more than their smaller, basic counterparts. Vent-free or ventless fireplace systems are significantly less expensive than direct vent fireplace systems; however, direct vent are by far more efficient than vent-free. Direct vent units also offer a more realistic looking fire. 

Finally, gas stoves fall somewhere in the middle price-wise, ranging from $1,400 to $2,200. Advantages of gas stoves include efficient heating and a vintage, old-world ambiance.

Type Cost Note
Firebox  $500 – $1,800 Cost depends on size and features
Ventless gas fireplace $1,300 – $2,800 Considerably cheaper than direct vent, but less efficient
Gas stove $1,000 – $3,100 Midrange option with vintage feel
Direct vent gas fireplace Up to $5,000 Most efficient with realistic fire


Gas Fireplace Add-on Costs

A basic system may not have all the bells and whistles you desire. Fireplace add-ons can enhance the performance, aesthetic, or both of the unit. Gas fireplace add-ons include gas log sets, burners, liners, and decorative accessories such as mantels and embers. All of these items will factor into the total price.

Log sets

Gas log sets are a big purchase with a large price range, so it’s important to understand the different types of gas log sets before you make your purchase. Ventless gas logs are more energy efficient than vented gas logs, but vented sets have a more realistic looking appearance. Vent free gas logs range in price from $450 all the way up to $1,800, and vented gas logs range in price from $550 to $1800.


Gas fireplace burners have a wide price range, costing anywhere from $220 to $2,000. There are a number of factors that contribute to this huge difference, including size and the number of features included. There are various types of gas log burners, including millivolt, variable, and intermittent pilot, and the style you need depends on the type of fireplace purchased.


Firebox liners are accessories that decorate the inside of the firebox for an improved aesthetic. Firebox liners may feature patterns such as brick or stone and range in price from $130 to $300.

Decorative accessories

Of course, you may want to add on some decorative accessories to enhance the look of your unit. Any additional decorative accessories that you choose to purchase will increase the cost of your gas fireplace. These accessories may include embers, fire glass, decorative logs, louvers, and/or decorative frames. Depending on the type of accessory installed, these add-ons can range anywhere from $30 (for decorative rocks and embers) up to $900 (for cabinet doors).


Gas Fireplace Installation Cost

Gas fireplace installation costs depend on the type of gas fireplace purchased. There are two main types to consider here: vented, and vent-free (ventless).

Cost to Install Direct Vent Gas Fireplace

Typically, direct vent gas fireplaces are more expensive than the vent-free type. Direct vent systems rely on outside air for combustion. They vent to the roof or side of the house in order to function. This can make them more appealing for homeowners who are sensitive to the smell of ventless gas fireplaces. 

Direct vent options also allow for more flexibility with installation compared to ventless, which often have restrictions on where they can be installed due to safety concerns. Direct vent fireplace inserts can be installed directly into an existing wood fireplace that’s equipped with a gas line.

Our direct vent gas fireplaces range in price from $1,750 to $5,000. Please note that this price range is for the firebox only and does not include the cost of a termination kit, blower kit, or other accessories. 

A contractor is required to install one of these units, and the installation cost will be greater than that of a ventless system. This is because direct vent units must be vented to the outside via the roof or the side of a home. The cost of a direct-vent installation ranges from $700 to $5,000 for labor only, and $2,100 to $10,000 with materials cost included. These materials include liner inserts, new vents, and gas tubing, as well as gas line modification.

Here are some of our most popular direct vent gas fireplaces:

Cost to Install Ventless Gas Fireplace

As the name suggests, ventless gas fireplaces do not rely on a chimney and flue. Instead, they use air from the room for combustion. These are typically less expensive than vented options since they require fewer parts to operate, and installation costs are lower. However, because there is no vent system with these fireplaces, they may emit an odor, which can be unappealing for some folks.

Our ventless gas fireplaces range in price from $400 to $1,530. Please note that these prices are for the vent free firebox only and that you’ll need to purchase liners, burners, and log sets as well. 

A contractor is required to install a ventless fireplace; however, the installation cost will be considerably lower compared to that of a direct vent fireplace because there is no venting required. The average cost to install a vent-free gas fireplace ranges between $2,000 to $3,500.

Gas Fireplace Running Cost

The cost to run a gas fireplace depends on three things: the cost of gas in your local area, the type of gas fireplace purchased (direct vent or ventless), and the fuel type you’re using (natural gas or liquid propane). Typically, natural gas options are cheaper to run than liquid propane options. Additionally, more heat is lost through direct vent fireplaces compared to ventless gas fireplaces; therefore, direct vent fireplaces are more expensive to run.

A small 10,000 BTU gas fireplace costs an average of $0.15 per hour to run. A standard 20,000 BTU gas fireplace costs around $0.30 per hour, while a 38,000 BTU unit can go up to $0.40 per hour.
