Vent Free Stoves
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.

I am switching to propane heat and I want to know how the ventless stoves process the water vapor from the propane. I prefer the ventless because of the high efficiency but I do not want all the water vapor from the propane in my home. Where does it go?

Answer:
The water vapor released into the room from the burning of propane is indeed one of the big arguments against using vent-free appliances, as it may cause windows to fog up and there have been issues with mildew in some cases.
