    History
    Installed Feb 8, 2011, replaced a steel one that got plugged burning spruce.
    100_5766.jpg 100_5767.jpg
    The center section of the combustor slipped forward.
    No sure when or why it got loose & it slid out about 1".
    Tried to push it back in, wouldnt' budge, didn't press hard thinking it would break easy.
    Last night I did a good burn down, warm stove & decided to fix it.
    As I pushed on it I could seethe center section was cracked, & I
    had to push it in to have room to slide the whole cat cartridge out.
    Well the center section broke.
    I tried to remove one of the side sections, as I did it had fractures & came apart in pieces.

    Also notice some were dirty, I had vacuumed it yearly but as the pics show , it
    never got totally clean inside.

    Luckily I had the SS cat, installed it, stove up & running fine.
    (It was cleaner than in the above picture, was only in the stove
    for 8 months 24/7 burning, so should have a few years life)
    Noticed the steel one light off a lot quicker.
    Almost 3 years, I'm guessing that's a reasonable life of a combustor ?

    The old broken one have any value for the palladium ?

    Might just start using the Stainless Steel ones.
    Will get a new one,
    & R&R them on an annual PM/cleaning.

    Any reviews out there as to which one is better?
    Ceramic or Stainless ? ?

    SS ones are much more sturdy :)

    Something doesn't seem right there. I pulled mine out after about 20 cord to clean it when performance dropped off...looked like new and is waiting for its turn to go back in.

    Dave, our ceramic cat went bad after a couple years (don't remember just when) so we got the steel cat. That was from the first batch that Woodstock got in and they had some problems with them. We put in another one and it is still going but the time it takes to light off is a bit slower than when new. When new, it fired up within a minute or two at most. Now it seems to take a bit longer but still going strong. I have another one which is one of the updates but have not yet installed it.

    Steel vs ceramic? Todd says he likes the ceramic best. So far I like the steel best.

    Strange that the center slipped out but it's not uncommon to see ceramic cats crack. They can be cracked and still work fine as long as they hold together. One of the advantages of s/s is resistance to thermal shock but they also seem to plug up sooner because of the smaller cells. BK has a 10 year warranty on their cats now so you may want to go through their dealer for a new one.

    I would say 3 years is too short.. I believe they are prorated after 3 years and I always got way more than 3 yrs on the CDW.. Looks like cats for that stove could be expensive..

    Looks like I should be pro active and order a new cat to have on hand so I'm ready when mine bites the dust.

    Also nice to have so that you can pull your working but maybe not ideally cat mid season and do a thorough cleaning if needed without worrying about not having a stove because the cat fell apart while removing it.

    Woodstock has great prices on SS cats.. Better than anyplace I have seen.. https://store.woodstove.com/home.php?cat=265
    I am pretty sure they are made by Condar..
    Do they have your size??

    What do you mean by "replaced a steel one that got plugged burning spruce"?

    I am seriously considering replacing my nc30 with either a BK or Woodstock's new steel hybrid and I've got about 3 years worth of spruce in the stacks. Is there a problem burning spruce in cat stoves?

    WS steel cats are made by Sud Chemie, I doubt they would have one for a King.

    I wonder what caused the center to slip? The rest of the cat looked fine, what a bummer! Mine has cracks but lights of just fine and still seems to work fine, as Todd said above cracks are not big deal as long as it's not missing pieces. Honestly I would've just left it alone, all the pieces were there it was probably working fine. Good thing you had the back up!

    We have to remember Dave has a longer burning season than most of us so his cat may not last as long as some of ours. It takes me two seasons to burn what he burns in one. I think I remember reading on the Condar site that a combustor is good for about 12000 after that it losses it's efficiency. Dave how many months do you burn 24/7?

    I believe BK uses these guys. http://www.firecatcombustors.com
