Ventless gas fireplaces are a good option for your home because they don’t waste any heat, are easier to install since they do not require a chimney, and cost less than traditional fireplaces.
However, ventless gas fireplaces can pose a safety hazard, since they do not vent any carbon monoxide that is created by combustion out of your home. Several states, including California and Massachusetts, prohibit installation of ventless models, so check the code requirements in your area.
If you do add a ventless gas fireplace to your home, be sure to install a carbon monoxide detector in the room. Watch this video to find out more.
