Gas fireplace inserts are a convenient and appealing way to add the warmth of a fireplace to your home. Many people enjoy watching the flames of a roaring fire or appreciate their warmth on a chilly night, but don’t love to clean up ashes or keep a stocked supply of firewood. Gas fireplace inserts are popular since they avoid the hassles of traditional woodburning fireplaces and offer a variety of installation and fuel options.
These fireplace inserts come in either vented or ventless configurations, so you’ll need to determine which choice is right for your space. Vented gas fireplace inserts will require a flue for external venting. On the other hand, vent-free fireplace inserts can be installed anywhere without needing an external exhaust route. The heat from a vented gas fireplace isn’t as intense since some of it is lost up the chimney. But a room with a ventless gas fireplace needs to be monitored for a build-up of carbon monoxide during operation. Fortunately, just about all units are equipped with an oxygen depletion sensor that monitors air quality. Other decisions will include whether to buy a model that runs on natural gas, propane, or either fuel source.
You can also purchase vented or ventless gas log sets. These can be used in traditional fireplaces or in gas fireplace inserts. Other options include purchasing a zero-clearance gas fireplace insert that will allow for just about any mantle or surround you have in mind to finish the look of your fireplace. Or, purchase a gas fireplace insert complete with a traditional mantle for a ready-made look. Whichever gas fireplace insert you choose, you can look forward to adding a bright glow and a warm, cozy ambiance to your space.
