Description
Excerpt: The key findings of the review included: (1) The NSPS certification procedure only qualitatively predicts the level of emissions from wood heaters under actual use in homes, (2) Wood stove durability varies with model and a method to assess the durability problem is controversial, (3) Nationally the overwhelming majority of RWC air emissions are from non-certified devices (primarily from older non-certified woodstoves), (4) New technology appliances and fuels can reduce emissions significantly, (5) The ISO and EPA NSPS test procedures are quite dissimilar and data generated by the two procedures would not be comparable, and, (6) The effect of wood moisture and wood type on particulate emission appears to be real but to be less than an order of magnitude.
