Wood and pellet stoves with actual efficiency numbers


The following 71 wood and pellet stoves have been tested by accredited laboratories for efficiency. Consumers should consider buying one of these stoves if they want a stove that has a reliable efficiency value.  However, with wood stoves, the listed efficiency represents what consumers can get if they use dry wood and give the stove sufficient air.  With pellet stoves, the efficiency reported by the lab is a good approximation of the efficiency the consumer can expect.  

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.

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.
