How is a "natural vent" fireplace different than vent-free? Is there an odor with vent-free fireplaces / fireboxes? Is it safe to use a thermostat with all vent-free fireplaces?

Our Answer:

B-Vent pipe is usually smaller in diameter than Class A chimney pipe (used for wood-burning/coal-burning hearth appliances), and it is much cheaper. However, B-Vent fireplaces and stoves have very poor efficiency ratings. As with a traditional wood-burning fireplace, B-Vent units are open and use the air from the room for combustion. As a result, you will lose a lot of heat up your flue or chimney as the exhaust travels out of the home, so don't expect to use these as a reliable heat source. Vent-free appliances can present a nuisance because the smell of the burning gas is bothersome to some people. It depends on how sensitive the occupants are to odors. It is indeed safe to use a thermostat with vent-free fireplaces that are able to accept a thermostat.
