Researchers have developed new testing methods for biomass room heating appliances reflecting real-life operation.
Recent firewood and pellet room heaters perform excellently under type test conditions. In contrast, typical real life emissions show significantly higher values under usual operation conditions. Consequently, type testing procedures may not account for real life stove operations and, thus, do not allow to distinguish between low- and high-tech appliances.
