So here we go, bought our first pellet stove used on Craigslist. Seller advertised it as a 4 year old Enviro M55 Free Standing with enamel finish. It looked good and we needed to large BTU output and we bought it for $1850. We go to get it installed and find out it’s a 2009 Enviro Empress FS. So smaller and 5 Year’s older than we were told. Now it’s installed and one of the fan motors is whining constantly. Can anyone tell me the value of a 2009 Empress vs a 2014 M55 FS?
