The Environmental Protection Agency has done a pretty good job at issuing guidelines for stoves of all kinds so that we are all working harder to protect our environment and making sure that it is healthy for a longer time period.
From the EPA website: "The traditional pot-bellied stove is a thing of the past – today’s
wood stove models feature improved safety and efficiency. They produce
almost no smoke, minimal ash, and require less firewood..While older
uncertified stoves and fireplaces release 40 to 60 grams of smoke
per hour; new EPA-certified
stoves produce only 2 to 5 grams of smoke per hour."
In regards to pellet stoves, the EPA says "Instead of logs, pellet stoves burn a renewable fuel made of ground, dried
wood and other biomass wastes compressed into pellets. They are some
of the cleanest-burning heating appliances available today and deliver
efficiency. Because they pollute so little, pellet stoves do not require
EPA certification; some manufacturers, however, voluntarily seek this
certification. Unlike wood stoves and fireplaces, most pellet stoves
need electricity to
operate, and can be easily vented through a wall, unlike log-burning
There are very good reasons for certification so read up on it and take your questions to Rich's for the Home when you go to shop for stoves. We are always happy to help you learn more.
