  • Works great!
Size: 3.5" x 14" x 3" Metal
This combuster is metal rather than ceramic. At the moment it is functioning better than the ceramic combuster. We have a Regency stove and really like the metal combuster over the ceramic. Things haven’t gotten really cold here yet but the fast startup of the metal combuster is quite obvious and much appreciated. Kudos to this vendor- good service and fast. ... show more

  • Midwest Hearth Wood Stove Catalytic Combustor Replacement
Size: 6" x 2" Round Ceramic
I have had my wood stove for 35 years & it keeps my home warm every winter very cheaply not having to burn electricity or gas to heat it. The original catalytic converter lasted 12 years & I replaced it with one from the vendor. Now the vendor is out of business & I had to replace that converter with a new one. This catalytic converter fit perfectly into my stove & works great for a price less than I paid for the last one many years ago. It will probably outlast me & keep the next family warm too! ... show more

  • AWESOME
Size: 5" x 10.6" x 2" Metal
I kept a lot of data on years of wood consumption before I was adamantly convinced of the value and performance of catalytic combustors. Altogether, we now have better than 40 years on several different Blaze King King-size stoves. You'll never know it if you don't keep really good records, but I've clearly discovered myself over the past 10 years, first a) that our combustors have outlasted the generally-projected 12,000-hour lifespan; but that b) by the time they do go, we're using almost twice as much wood over a season for the same heating needs. Required chimney maintenance dramatically increases as well. Research encouraged me to try a metallic combustor this cycle... and reviews, cost, and other information decided the next experiment would be to try the Midwest Hearth brand. It fit tight in our stove (as it should, with the gasket), but was easy to get installed. Firstly then, I'm happy to report that our experience corroborates claims that the metallic combustors get up to catalytic temperatures faster than the ceramic types. In fact, with our 2015 Blaze King KE1107LBK, we can just shut the bypass on a relatively new fire, long before the metallic combustor would get up to catalytic temperature, and exhausting the smoke thru the combustor at this early stage all-the-sooner engenders catalytic activity... a few minutes later. Our smoke is clear and odorless, and for better than a week, early fall experiments easily got 24 hours of good heat out of single 16-inch half-rounds of lodgepole and red fir. I didn't even bother trying tamarack. We've got outdoor temperatures in the 20s now, but our house is still toasty thru these colder weeks on a 16-inch half-round every 12 hours now. I'd have been filling the stove every 12 hours to get that kind of heat last year, on a near-expired stock ceramic combustor. We're at 4,300 ft elevation in eastern Oregon, and rely entirely on wood heat. The first year on this stove, on its new ceramic combustor, we used 2.75 cords to keep the house warm over a season that runs pretty close to 8 months. Last year, at the end of the original ceramic combustor's life cycle, we used just over 5 cords for a bit more moderate season. I'm projecting right now that we'll get thru what's already a very early and colder winter this year on about 2 3/8 cords. The stove is giving off an impressive increase in heat with a much smaller load of wood... and the wood is lasting longer than ever. I'm impressed. ... show more

  • Fits well, does the job.
Size: 2.5" x 13" x 2" Ceramic
This is a necessary part to keep the stove functioning efficiently. However, it’s not the best design as it seems to last only a few years before needing replacement. The honeycomb is very fragile and cracks easily when there’s any moisture in the wood. Best to burn only well seasoned pieces and to keep the temperature from getting too hot as it will cause the honeycomb to crack. ... show more

  • Prepare and buy a spare
Size: 3" x 18.5" x 2.5" Ceramic
We bought a spare about five years ago and when it came time to use it, had a hard time finding this catalyst to replace it on our shelf. The newest Hampton uses the same model, so the supply ought to be good. The company we hire to clean the flue and maintain the fireplace does not keep them in stock, explaining they would tie up too much money in parts inventory. Seems short-sighted, but you should check your local support before you get surprised. They took one out of a floor model when ours cracked the first winter, and that's why we stocked up with a spare. Otherwise the catalyst frame and the honeycomb are identical to the original, and fit correctly above the firebox. Recommended. ... show more

  • Product does not last
Size: 2.5" x 12.75" x 1" Metal
We have tried several of these, but the ceramic and the metal ones don't last a full season. Our stove is used 24hrs a day all winter. Maybe other people just use their stoves occasionally. We find this does not hold up for our usage.
