Consumers should beware that most manufacturer websites post unreliable and exaggerated efficiencies, except for a small group of companies. Some companies may not post the efficiencies of their pellet stoves because they are poorly designed and have efficiencies below 65%. Click here for an analysis of stove efficiencies.
In addition to the approximately 150 stoves on the EPA list with actual efficiencies, the Alliance for Green heat obtained actual efficiencies from the EPA on five other stoves. The Harman Accentra 52i at 76%, the Quadrafire Mt. Vernon E2 at 75%, and the Ravelli 100 at 70% and Ravelli 80 at 56%. The Alliance obtained these efficiencies through a Freedom of Information Act request and received this chart.

How to read this chart: Some of the Model Names have been shortened to fit into the format of this blog. To check the official source of certified stoves that would contain the full model name(s), refer to the list of EPA certified stoves. The emission rate is the number of grams of particulate matter that make up smoke, per hour. The actual efficiency refers to a average of the range of heat outputs that the stove is capable of, calculated using the CSA B415.1-10, which uses the higher heating value (HHV). Under type of stove, "Cat" refers to catalytic stoves, "Hybrid" refers to stoves that have both catalytic and non-catalytic technology, and "Non Cat" refers to non-catalytic stoves.
