Labs Test for Actual Efficiency of Wood and Pellet Stoves

In May of 2015, the Environmental Protection Agency began to require efficiency testing for stoves. Those tested and certified before then do not have to disclose their efficiency until they are required to conduct new tests – while will be at least a couple of years.

Many stove manufacturers post efficiency numbers based on non-standardized calculations. This means the information posted on the company website might not be entirely accurate.

The wood and pellet stoves found in the chart below have been tested by accredited laboratories for efficiency in order to find honest data for consumers. Keep in mind that the efficiency of wood stoves is partly based on the operator, while lab-tested pellet stove efficiency results should be considered reliable.
