any secondary burn that routes the exhaust to the rear of the stove is junk, cat or not. the best cat stoves i have ever run into are the woodstocks, as their cats are underneath the stove top, thus routing all that usable heat to a spot on the stove where it (generally) works the heat into the room and not the back of your hearth (they are also cast iron housings for the cat, which i will get into the housing in a minute!)... some of the Old and new CDW stoves routhe the exhaust in the same fashion, but there are too many parts in there for my liking... a good non cat stove with a simple tube style system and a baffle will work great for you. Most of these top load stoves you see out there (with the "firedome, afterburn or everburn et all" rear secondary) systems were all designed by old VC engineers... this must be a pretty good gig for them, cause they had one idea about 20 years ago and keep shooping it around and peddling it to all these companies that want to build a stove to compare to the VCs. ask the sales guy to let you touch the secondary burn chamber in these rear routing cat and non cat stoves which introduces 2ndary air or holds the cat in place, just touching the fragile fiber crud in the back, and seeing how you have to handle it several times a year to clean it, will turn you off from these units.
I feel opinions are like a-holes. Everyones got one
No offense to you summit, just makin a joke. But seriously, keep that in mind when your are deciding on your cat or not cat stove. I'm about to give you opinion.
Summit mentions above that all stoves that re-route the exhaust to the rear of the stove are junk, well, I don't agree. I think it really depends on your stove and whether it is cast-iron or steel, whether it is correctly sized, who makes it and where it will be placed (in a fireplace hearth or on a platform hearth). I own a Jotul F600 cat model which is a rear-diversion cat stove. I also have a heat deflector shield to deflect heat away from wall. Traditionally rear diversion stoves need more clearance from walls creating intrusion into the room (one reason they are not liked). Some models are speced to use a heat shield (must be manufactured approved) My Jotul is set up for this. Anyway this stove absolutely cooks and I can't see it ever being refered to as junk. It will outperform many other stoves and is built solidly. Further more Summit stated "needing to clean the cat several times a year". NOT TRUE! I clean mine once a year. If you burn seasoned wood or at least semi seasoned wood, and you wait until the stove is up to temp before you turn the cat on (open the diversion) there is no need to clean the cat more than once a year. The catalytic combuster (not the stove, my stove is over 10 years old) usually last 5 years then you have to buy a new one for about $150.00. I have heard of people getting ten years out of one. This is not alot of money when you think about it. To clean the cat, all you need to do is soak it in white vinegar for a day and then air dry it, don't scrub them, they get fragile as they age. As far as the insulation around it, yes its delicate but its also sorounded by cast iron plates so the only time its exposed is when you are doing maintinance, all it takes is being gentile when handling the cat once a year. Don't be a caveman. As far as top loading, I love mine. There is nothing like coming in with an armful of wood, stepping on a top loader lift pedal and dropping the wood in. No ashes dropping out of the door, no wood wanting to roll out. So basically my TOP LOADER, REAR CAT stove has made me very, very happy for the last two years of burning. I think summits use of "all" when refering to "some" stoves is no help to you and does you no good when investigating stoves. Without a doubt there are bad stoves of all designs, its up the forum members to share their unbiased information based on experience.
The cat stoves in "my opinion" are slightly better than non-cat stoves since they are more controlable, burn cleaner (not all, but most of the good names), give longer burn times and are far prettier to watch when burning.
So I have to disagree with Summits post. From time to time you find a Jotul f600
cat model (they no longer make them due to being to expensive to make) on craigs list. I have been keeping my eye out, for if I do find one I would snatch it up to use in my timber frame.
Either way you go, you will be happy if you stick with a good name. I agree with Summit that woodstocks are a quality product, but I lean towards Jotul since they have been doing it along long time. Anyway I hope this helps. I do agree with the others about staying away from VC, not alot of good recent history there.
