The Difference Between Vented and Ventless Gas Logs
If you decide to install a gas fireplace, one of the first questions you’ll be asked is what kind of gas logs are you interested in: vented or ventless? Most people aren’t prepared for this question. This blog will break down the differences between vented and ventless gas logs so that you are prepared to make a choice.
Vented gas logs look more realistic. The first major difference is that vented gas logs look more like a real flame than ventless gas logs. Vented gas logs dance around the logs and the flame is much taller. The flame is also more realistic in color than ventless logs.
Ventless gas logs are more efficient. Vented gas logs are more realistic, but ventless are the way to go if you’re looking for efficiency. Ventless logs disperse almost all of the heat into the room and use slightly less energy than vented logs.
Burn vented gas logs with the damper open. Vented gas logs produce exhaust that goes up the chimney. One nice thing about ventless logs is that they are so efficient that they can be used with the damper closed.
Ventless gas logs need some ventilation. You can burn ventless logs with the damper closed, but that means the water vapor and carbon dioxide (CO2) that are byproducts can get into your home. You should make sure a room with ventless gas logs is properly ventilated to prevent mold or mildew caused by excess moisture. Some people are also irritated by the smell of CO2 which makes ventilation even more important.
Vented logs are great if you want a realistic looking fireplace, and ventless are better if your main concern is energy efficiency.
