Unlike vented gas logs, ventless gas fireplace logs do not require a chimney. In addition, almost 100% of the heat produced by this type of fireplace remains within the home, making this an extremely efficient option. When considering ventless gas fireplace logs, it is important to know that a few states do not allow this type of option, to include Alaska, California, Colorado, Massachusetts, Minnesota, Montana, and Utah.
The ventless gas fireplace option has a feature called an Oxygen Depletion Sensor, ODS. In this case, whenever the oxygen level in the air drops below what is considered a safe level, the ODS cuts off the flame. While this problem does not happen very often, this is a great safety feature. A terrific benefit of ventless gas fireplace logs is that they can be burned in either a regular wood burning fireplace or a prefabricated ventless firebox with no chimney. In addition, ventless logs do not require the damper to be opened. Ventless gas fireplace logs produce a blue flame while vented gas logs produce a yellow flame. In addition, ventless gas fireplace logs are made to produce far more heat, and burn cleaner. Many people feel that the blue-flamed fire is not as appealing as a yellow-flamed fire but keep in mind, the main determining factor between the two types has to do with the amount of heat produced. In general, when it comes to sensibility and the best option for heating your home, ventless gas fireplace logs wins hands down. Best of all, the operating cost is only a few cents per hour of use. Keep in mind that ventless gas fireplace logs do not need electricity and therefore offer a perfect solution during bad weather and power outages. Many fireplace professionals will tell you that the ventless option is the most realistic and safest choice you can make. However, before you make your final decision, here are a few other considerations. If your home is not well ventilated, you may need better ventilation before your ventless gas fireplace logs are installed. Then, if you have other appliances that burn fuel, they are using the inside air as a means of combustion. If ventless gas fireplace logs will be located in close proximity to any of these other appliances, you will need to ensure there is appropriate fresh air in order to support all of the appliances. Additionally, homes located at high altitude (above 4,500 feet above sea level) such as Colorado often have trouble with the pilot light going out because of low atmospheric pressure. Finally, ventless gas fireplace logs are beautifully designed to look just like real wood so consider the appearance you want to enhance your home and set the mood.
