are working to encourage the use of more efficient wood boilers instead of the older dirty models. The Greenwood Aspen Series, for example, emits only 8.4 grams of particulates per hour, compared to over 70 grams per hour from older technology.
Experts on wood-burning products say there is no independent way to verify the company's claims. The units cannot be sold in Washington because the boilers release more than the maximum 4.5 grams of particulate matter per hour.
Greenwood Technologies' heating products meet the strict requirements for efficiency and emissions set forth in the EPA's Outdoor Wood-fired Hydronic Heaters (OWHH) program. The Aspen Series also meets the even more stringent Phase 2 requirements.
