Ventless gas technology, available in various sizes to suit your home, is the most efficient vent-free option one can use in an existing masonry or pre-fabricated wood-burning fireplace. It also gives one total control over the damper position. Despite the common misconception, ventless log sets can be used as purely ventless (without a damper or with a damper closed), partially vented, or fully vented – a versatility that the vented log set technology cannot offer.
When operated in vent-free fashion, vent free gas fireplace technology is 100% efficient, making the money spent on natural gas or liquid propane well worth the output in heat. Since any fire needs oxygen to burn and produces CO, CO2, water vapor, and smell, ventless gas fireplace logs will be using the room air for combustion and will emit the above-mentioned by-products back into the room. This scares some people, but in reality, using this technology is no different than cooking on a cook top stove.
When compared to a vented gas log set, ventless fireplace logs are nowhere near as pretty or realistic, but they can be used as a secondary furnace if desired, adding a warm glow to your hearth. This added efficiency and functionality make them a valuable addition to any home.
All vent-free products have oxygen depletion sensors (ODS) built in them, which is a nice piece of safety equipment for peace of mind. Should the ODS sense that the oxygen level in the room is approaching an unsafe level; the unit will turn itself off. That way there is no more heat, no more flames, no more exhaust, and, ultimately, no more oxygen being depleted from the room by the fire.
Due to their nature, ventless gas fireplace products cannot be installed in bedrooms, must feature 40,000 BTU's or less, and comply with specific clearance requirements designated by the manufacturer and/or fire code.
Log sets are not the only option when it comes to having vent-free technology installed inside an existing wood-burning fireplace or a vent-free firebox. For people who prefer a modern look to an imitation of a conventional wood-burning fire, there are options of contemporary burners with glass and river rocks, along with simple "linear" burners. Some models even offer dual fuel capability, allowing you to choose between natural gas or liquid propane. These burners, designed with style in mind, function the same way as traditional log sets, hence all the above-mentioned characteristics, requirements, and restrictions apply to them as well. Whether you live in the mountains or the city, our site offers a hand-selected collection of ventless fireplace logs to fuel your home's warmth and provide the perfect design for your space.
