Standard type testing methods for biomass room heating appliances have driven technological development tremendously in the last decades towards low emissions and high efficiency. However, they are not suitable to reflect real life performance as operating conditions and user habits are not sufficiently considered in the test procedure. Several studies revealed a major contribution of batch fired room heating appliances to harmful gaseous and particulate emissions. Consequently, there is the need to optimize the combustion performance of these technologies in future significantly, especially in real life operation. Advanced test procedures implemented in normative standards or labels are effective instruments to assess product quality and to trigger technological development. Therefore, a new test method for firewood roomheaters (EN 13240) was developed focusing on real life operation performance. The test procedure is based on a European survey on user behavior, long term field monitoring as well as comparative combustion tests under laboratory conditions. Validation tests confirmed a high repeatability of the testing procedure of the suggested test method "beReal-Firewood".
