A vent-free fireplace is a perfect choice for a homeowners who want options, not limitations. Vent-free fireplaces don't need vent pipes or a chimney, they draw air from the room. And because they don't need venting, they can be placed anywhere on a wall and in almost any room, giving a home owner even more options.
With stringent design requirements, vent-free fireplaces are precisely engineered to create almost 100% complete combustion. This means that you don’t need to worry about harmful exhaust filling your rooms. Most vent-free units will exhaust water vapor and carbon dioxide, not dangerous gases like carbon monoxide.
And because there isn't a vent system, a vent-free fireplace is completely efficient, making it one the best heating sources. You won't have to worry about losing heat to a chimney or exhaust vent, because there are none. This makes a vent-free unit the best choice for a heating source.
