The performance of residential-scale woodburning appliances is of interest because use of these appliances can have significant impacts on been developed so that energy efficiency and emissions can be measured under standardized conditions. During Phases 1 and 2 of this project, the accuracy of these methods was demonstrated for a wide range of appliances including catalytic stoves, conventional stoves, and fireplace stoves. Although some of the flue-loss test methods have good accuracy, there are serious concerns about whether laboratory test results correlated with field performance, i.e., do stoves with relatively high laboratory-measured efficiencies give relatively high efficiencies in field use. The major concerns are the lack of realism due to use of standardized fuel (dimensional lumber with enforced air gaps) in laboratory tests and the possibly rapid degradation of appliance performance. In Phase 3 of this project, three tasks were undertaken: the effect of fuel choice on test results was investigated in a preliminary way; an in-situ efficiency measurement system was developed and tested against the universally recognized reference method (room calorimetry) for efficiency; a flue-loss method developed during Phases 1 and 2 of the project has been demonstrated to be accurate when applied to pellet-burning appliances.
