  • High Quality & works great!!!
Size: 3.1" x 20.5" x 2" Ceramic
I was having issues with my Lopi woodstove, smoke would leak through into my house. Wood wasn’t burning good & it wasn’t putting out the heat as usual. After much research, I found out it must be the catalytic combustor. Buying from Travis industries, who makes Lopi were charging over $800. I found Midwest Hearth online, my catalytic combustor was $329. Comparing the two online, they seemed to be equivalent. My ceramic combustor was scheduled to arrive Sunday. To my surprise it arrived a day early on Saturday. Comparing the old combustor to the new Midwest Hearth combustor, they looked almost identical. I cleaned out the stove and installed my new catalytic combustor. What a difference!!! The fire burns beautifully, NO SMOKE, even with door cracked open to get fire 🔥 going. The quality is great, installation was easy & the fire burns bright & strong!!! Can not recommend this company enough!!! They are GREAT!!! ... show more

  • 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

  • Perfect fit for my Blaze King Princess fireplace insert
Size: 4" x 10.6" x 2" Ceramic
We've had the BK Princess for about 11 years. I clean the catalytic cumbustor a couple times a season when we have warmish days and I can power-sweep the chimney at the same time. My white oak firewood isn't always the driest, so I power-sweep the chimney from the underside and brush clean the cumbustor at the same time. It seems to have worked as I am only now replacing the cumbustor for the first time in over a decade. BTW, we burn about 2 cords of oak per season. We live in the Mid-Atlantic region. Last year, I saw that the back side of the cumbustor was starting to flake/chip away. It appears to have reached end of life. This replacement looks just like the original with the gasket material already installed. With the first fire I lit, we noticed a big difference. I could now turn the air flow down to almost nothing and have the heat output way over to the right of the temperature gauge. This is how I remember the Princess on its first year of duty. I am very pleased at this point. As I said, I got about 11 years out of the first catalytic cumbustor and I can't foresee how long this one will last, so I gave the overall rating as a 4. If it lasts 5 years, I will append the rating to a 5. Right now, it's a thumbs up. ... 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

  • This combuster is metal rather than ceramic
Size: 2.5" x 12.75" x 1" Metal
We just cleaned the chimney getting ready for the upcoming winter. When I vacuumed out the fireplace and the combustion chamber the catalyst still was in great shape after one full season. This is being used in a Defiant Vermont Casting. We burn pretty much 24/7 and use 6 cords of seasoned oak in a season. We went through a ceramic one every year, got tired of buying a new one every year. ... 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
