Which is Which? The Difference Between Vented and Ventless Gas Logs

Posted on

As the winter season settles in once again, homeowners are likely looking for gas logs for their fireplaces. Most of them, however, feel overwhelmed with their choices as they search logs that most closely resemble a real wood fire. Most of them are torn between vented and ventless gas logs, and it is important to know the differences in order to pick the best choice for every fireplace.

Vented Logs

This type of log is the most popular choice among homeowners, since it is able to provide the most realistic look compared to firewood in a fireplace. Vented gas logs are intended to be used within a gas-powered fireplace, with the damper opened. You have a lot of choices when it comes to vented gas logs as these come in different wood designs, including oak, birch, and hickory.

If you choose to go for vented gas logs, remember to check if your fireplace has a flue or a chimney to get rid of carbon monoxide. Also, the dampers should be locked in the open position at all times when the vented logs are burning.

Ventless Logs

Considered a technological marvel, ventless gas logs contain special burner elements, allowing them to burn gas while producing less carbon monoxide. Most ventless gas logs are certified by the American Gas Association and often comes with an oxygen depletion sensor. These sensors detect the oxygen levels within the room, and will shut off the gas supply to the logs once it sees that the oxygen level drops to a particular percentage.

If you’re looking for a more energy efficient choice, ventless gas logs are the best option. Since you can leave the flue closed, you can use your fireplace as a temporary source of heat, especially during a power outage.

Before Installing Gas Logs

Whether you’re going for a vented or a ventless gas log, remember to prepare your fireplace for installation. Make sure that your chimney is cleaned, as gases produced by these logs can still build soot within your fireplace. Also, make sure that the area around your fireplace is free from any item or material that can burn, melt, or be damaged. More importantly, your fireplace should have grating as a safety precaution for everyone in the family.

Finally, never install gas logs on your own. The installation of gas logs is not a DIY job and will require the help of an HVAC professional. Experts like those from Buchanan Fire and Outdoor in Greenville, SC can provide installation services to almost any kind of fireplace, be it a propane gas fireplace or the like, so you can be assured that your fireplace, as well as your home and family, is in safe and trusted hands.
