"To be considered, a stove must use the burning of biomass fuel to heat a dwelling unit or to heat water for use in such a dwelling unit, and have a thermal efficiency rating of at least 75% as measured using a lower heating value;"
Reason I ask is that I have looked at lots of stoves and inserts lately that say they qualify for the credit but the efficiency rating listed from the mfgr is below 70%. Is there a difference in how they are rated and/or tested? Is thermal efficiency different than the mfgr's effiency?
Thanks,
Rob
