    Ventless or Vented gas logs

    I need to hear from the experts here. My wife is adamant she wants a gas log fireplace. We do not have a chimney in our home, so I have to decide whether to go ventless or vented. Considerations are many, safety being number one. Cost is also a consideration. I would love to hear the pros and cons from those with experience on this subject. BTW, it will be propane as we do not have natural gas as an option in my area.

    Vented, never ventless
    If I do a job in 30 minutes it's because I spent 30 years learning how to do that in 30 minutes. You owe me for the years, not the minutes.

    Ventless has been outlawed in many areas for good reason.

    X3. In many areas (rightfully so) ventless are illegal, and aside from the potential CO issues and oxygen depletion, they release high amounts of moisture and smell bad. At the very least the flames do not look very real (like a vented gas log can depict a fireplace). If it fails, no one will or can work on it.
    A direct vent fireplace can be installed in lieu of having a chimney and you can get a large enough unit w a blower option that can efficiently heat most of the home if desired (or if your furnace fails). It's also an asset to your homes value, not a cheap appliance.
    If price is an issue, just go w one of the higher end top rated electric decorative fireplaces, at least they look real.

    Ventfree are tested in a lab to emit no more than 200ppm CO. That's not in a home with foot traffic, kids playing, and other forms of air movement that can cool the flames and cause flame impingement. That results in incomplete combustion which leads to CO, soot, aldehydes, and NOx production. You burn for 3 hrs you've produced a gallon of water vapor

    You either love VF or hate it--no middle ground. '
    DV does not use room air, does not emit flue gases into the home and is very efficient.

    I always thought ventless types were a bad idea.

    Thanks for the info. You guys have convinced me to go vented. The cons of ventless far out weigh the any reason for using one.
