Its hard to compare, Seasoned Oak.
A 600 degree stove top on a Blaze King is different than a 600 degree stove top on a non-cat.......For starters , the BK top temp is centered around where the cat is and not the sides front and the whole firebox like a non-cat is. So your heat is dispersed differently. And heat is added to by the cat which slows the burn down which brings more of the heat into the room which would normally go up the flue.
Two different technologies ......I have had both non-cat , hybrid and cat stoves and I can tell you they all get the job done when its cold......The cat stoves just have a wider range of burn choice and control which is really nice when temps aren't so cold. Also I get a longer burn on a cat stove when its cold than a non-cat . Even though that burn time is shorter on the cat stove than it would be in the shoulder season. Hybrid gets a bit longer burn time than the non-cat , but not as long as a BK.
I've got the hang of cat and non-cat stoves now. I'm trying to understand hybrid stoves at the moment. You said you've had all 3 types so I want to ask you, do all your comments about cat stoves having a wider range of burn choice (especially on the lower temps during shoulder season) apply to hybrid stoves to the same degree as cat only stoves? Or to ask the question another way, Can you burn a hybrid as low temp as a non-hybrid catalytics?
