Understanding the Difference Between Vented and Ventless Gas Fireplace Logs

If you’ve shopped around for gas-burning fireplaces for very long, you’ve probably heard about vented gas logs and non-vented logs. Is one style better than the other? Which would be best for your home?

fireplace insert installations in Destin FLDoodlebuggers Fireplace, Grill & Outdoor Store of Pensacola, FL, and Destin, FL, would like to give you some helpful information about each style of gas log to help you make the right decision.

The primary difference

Vented log sets are designed for use in vented fireplaces that draft combustion gases out of the unit, similar to traditional fireplaces. Vent-free log sets require no venting, and the fireboxes they’re used in are completely self-contained appliances.

Vented vs. non-vented gas logs

Let’s look at some specs on each style of fireplace log.

Legality

Certain areas of the United States – the entire state of California, for example – have banned the use of non-vented gas fireplace logs. Before you purchase a vent-free gas log set or a fireplace that’s designed for them, check with your city, county or state government.

Gas line connection

Both styles of logs will need to be connected to a natural gas or propane source. This connection should be made by someone familiar with the process.

Flame appearance during use

Vented logs exhibit robust and dazzling flames, while non-vented logs tend to produce smaller, less-exuberant flames. Both log types can be enhanced with attractive faux ember beds and other amenities that present stunning firebox backdrops. 

The “look” of the logs

Vented and vent-free gas logs both come in a range of attractive designs that look quite a bit like natural wood logs. They include unique bark patterns, curious shapes and realistic colors to give your fireplace a “traditional” feel.

More heat with ventless

Ventless gas logs will bring more heat to your room than vented logs. If heat is a key reason for bringing home a set of gas logs or a gas fireplace, go with ventless if this style is lawful in your area.

Fuel efficiency

Because vented logs run with an open drafting chamber, some of the heat produced will be lost during combustion. The completely closed system of a vent-free fireplace retains more heat – as much as 99% of it, according to some studies.

Odor and moisture

Two possible drawbacks with non-vented gas logs are the odors and moisture they sometimes produce in the air. Vented logs do not present these drawbacks.
