Are Unvented Gas Log Fireplaces Right for Your Home?


Over the last few years, the unvented gas logs have become extremely popular. More and more people are attracted to the reasonable price and inexpensive installation, but if you are one of those people looking to purchase an unvented gas log fireplace, keep in mind several things. First of all, it’s important to know that there are two basic types of gas logs: the vested gas logs and the gas logs that are not vented at all. As you probably know the carbon monoxide produced from burning gas or wood is extremely dangerous. It is a lethal gas which can affect your health. However, this is not the case with the unvented gas logs which are specially designed to produce a hot flame. The flame produced by these fireplaces decrease the levels of carbon monoxide.

As compared to the gas logs that vent to the outside, the unvented fireplaces come with an Oxygen Depletion Sensor. This sensor stops the carbon monoxide from reaching to a dangerous level in your room. Despite the fact that it is equipped with this sensor, it’s recommended to install more carbon monoxide detectors in your home. In some states, these detectors are required by law. Contact your local council to find out if you live in a region where the carbon monoxide detector is mandatory. The unvented fireplaces are a low-cost alternative to those fireplaces with chimneys and flues. They are more efficient than the vented fireplaces, but they require good ventilation. The latest models are equipped with an automatic thermostat which will help you control the heat output and with a convenient automatic ignition feature.

Where can these types of gas logs be installed?

Some unvented gas logs can be placed in masonry fireplaces, while others can be housed in special fireboxes. Some of these vent-free gas logs are mobile and can move around from a place to another. Nowadays, people are more annoyed about the dangers with such gas powered units. However, some people don’t even know how to use and operate an unvented gas log fireplace.
Another problem regarding the use of this device is the moisture. If you are thinking about purchasing a vent-free gas log, keep in mind that you might have some issues with the moisture. If you have a vented gas log, you already know that the moisture escapes out the vent, but if you own an unvented device keep in mind that all that moisture enters your home. This can be great during the cold season, but it’s recommended to avoid using a humidifier because it may cause condensation and moisture on cold windows.
