This isn't the article I read before but another testing of 7 year old stoves.
http://www.omni-test.com/publications/Long-Term.pdf
Of interest to this thread is the following
"Of concern has been the fact that laboratory and field studies have shown that certified
wood heaters can physically degrade with use and their air emissions commensurately increase."
"deterioration of the catalyst over time was estimated to result in emissions from catalytic wood
heaters over their useful lifetimes approximately equal to non-catalyic wood heaters."
And
"The particulate emission factors of the certified Phase 2 stoves evaluated in this study
appear to have increased with use, but on the average, after about seven years they still have
lower emissions than uncertified conventional stoves. In addition, it was clear from the results
that the emission rates for Phase 2 stove models reported as part of the NSPS certification
process do not represent emission levels of same stove models inhomes after extended use."
I work with the EPA division of air quality here in Ohio on a steady basis and I understand their language. In words that us normal people would use in every day conversation that last quote should say
The emissions of the phase 2 stoves did indeed increase but still are somewhat lower than non regulated stoves when averaged by this test. (this tells me that some where higher or they would have said ALL stoves, not average.) AND FINALLY the last sentence, the truth comes out, well kind off.
They are not the same stoves after 7 years as they were when manufactured. In our words, they no longer do what you paid for and they are just like my dumb ole 1975 Arrow. So guess what is going to be next on the hit list boys??? your gen 2 stoves. Are you gonna turn them in or join the fight??
