If you want to get fiery log pragmatism, as well as fully efficient, 100% heat generation, choose vent-free gas logs. To reinstate your wood fire, bring in some monitored space heating and provide a emergency backup heat source option to make your home warm, ventless gas fireplace logs may be your ultimate solution! Vent-free gas logs have become trendy in the recent years and their sales in numbers are rapidly catching up with the sales of vented logs.
In a great breakthrough in the evolution process of gas logs, few genius engineers laboriously researched to produce a yellow flame in an isolated environment with these sets, without compromising a clean burn. They came up with a new technology which involves specifically designed burning elements that emit much reduced amount of carbon monoxide in air. They are "Vent-free", meaning, they don't require a chimney and hence the heat produced is circulated within the confined place of your home.
Gone are the days, when you were required to collect the logs of costly firewood. Vent-free gas logs come with their own sets of gas logs which cut down the costs significantly.
100% Energy Efficiency
As, vent-free gas logs don't require a chimney anymore, it ultimately becomes highly energy efficient. In other types of gas logs, which involve chimney as their venting source, almost 80% to 90% heat escapes through chimney, which is prevented in these systems.
Because of the specific burner elements present in the system, this system produced much more controlled burning compared to their other counter parts. This controlled burning helps in producing clean, yellow flame causing complete burning of the gas logs.
Due to the controlled burning of vent-free gas logs, very less amount of carbon monoxide (the by-product of combustion) is released in the air, leading to reduced pollution. Ventless gas logs certified by the American Gas Association (AGA) come with Oxygen Depletion Sensors (ODS) which can identify the level of oxygen present in the room. If it is depleted beyond the marked level, then these sensors cut off the gas supply to the logs resulting in standstill of the system.
If the sensors become defective due to any reasons, the system automatically switches over to safe mode where it cuts off the gas supply.
No Ashes or Sparks
Unlike their previous counterparts, there is a complete absence of any dirty ashes or dangerous flash and sparkles in vent-free gas logs, thanks to the presence of spark screen.
Vent-free gas logs give you the facility of instantly switch heat on and off. You can control the system by both ways- manual or remote. There is no more creosote buildup (which is a thick yellow to brownish oily substance derived from wood tar or possibility of chimney fires).
Huge amount of water vapor is produced by vent-free gas logs. It is estimated that approximately 1.5 gallons of water is produced for every 100,000 Btus of gas burned. As these systems burn around 30,000 Btus per hour, it takes them only 3 ½ hours to produce such amount of water. In case of vent-free gas logs, these vapors can condense on windows and other cold surfaces, creating severe moisture problems. Hence, these products come with directions for leaving a window slightly open during use.
Vent-free gas log systems are not permitted to be used in bedrooms or bathrooms. Some people consider them not as attractive as their counterparts, as they can't get an amber effect, since they can't cover the system. Of course, much has been changed since, as they also started displaying the sought after aesthetic appeal. Vent-free gas logs don't allow any addition or re-positioning of logs, as is possible with their other counterparts.
Certain states like California, Alaska, New York, Utah, Massachusetts, Colorado, Montana, and Minnesota still prohibit the use of ventless gas fireplace Logs. Few municipalities in other states may also prohibit their use. So, it is your responsibility to check with your local building department, prior to purchasing your set. Check for the AGA (American Gas Association) seal on the product. Ensure that manufacturer's instructions are followed at the time of installation.
In summary, there can be nothing comparable to a ventless gas fireplace, installed at home during the chilly winter. It provides the best option and most economical way of heating, to keep your home warm!
