Question: are pellet burners any good?
Answer: Up to 90% efficiency, and even more. The efficiency of a pellet stove can be as high as 90% or more. ... This is more than a classic wood-burning stove, with an efficiency of only 40 to 50% (60 to 80% for recent high-efficiency stoves) and much more than an open fire, with an efficiency of 5 to 15%.
