Have a local sales/installer sells both Empyre and Woodmaster, he is pushing me towards the empyre but not liking what I've read. Seems like lots of corrosion but most have either the 100 or early 150, and nobody is saying they have enjoyed their customer service. Sales man here said he did replace some of the early units and felt a lot of the problems were moisture content of wood, and that empyre stood behind their product by giving new stoves. Also said that the new SS is the way to go as it laminated over the original giving "twice" the protection but is starting to sound more like a patch. I asked if any one is running woodmaster in the boiler room and got crickets, gonna pop over to the biomass forum and see if they are hiding over there. Thanks and love the site!
