Vent-free wood stoves are ideal for homes with limited space. Since they don't require any bulky vent pipe or external attachments, you can place ventless stoves in places you would never be able to fit vented models. Similarly, if you're searching for efficiency, you're definitely going to want to go with a vent-free stove. This is because while vented units can lose a significant amount of the warm air they produce up their chimneys, ventless wood stoves are entirely self-contained, allowing all of the heat to remain inside the home.
Where does the smoke go if one does not have a vent?
Vent free appliances are manufactured so that they do not release soot or CO when burning. The burner is designed to facilitate and optimal fuel ratio, with no obstruction to the flame and the release of only carbon dioxide and water vapor. It is important to note that they do use oxygen from within the room for combustion and as such, they do not work well in smaller spaces and high elevations, due to the lack of available oxygen.
