Was talkin Cat with Steve today of Vermont Elm stoves and asked why he doesn't push the cat more. He said because most people won't maintain or replace as necessary. Sure they are a step up in clean air operation but a cat stove in bypass might be worse than an old smoke dragon. I got to thinking about a person I know with a cat stove that is like 15yrs old and they say I ain't buyin that 100.00 cat. Stove still works why do I need it. I'll bet that goes for most people operating cat stoves today. I know people on here are doing it right but the average jo on the street isn't into it like we are.
