Midwest Hearth Wood Stove Catalytic Combustor Replacement Catalyst Blaze King Princess (4" x 10.6" x 2" Ceramic) Made in USA

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!!!

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.

A difficult item to find, that was shipped promptly. A perfect fit in my Blaze King Princess stove

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.

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.

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.

My old catalytic combustor was broken and cracked. This new one has improved the perfomance of the stove drastically! I wasn't sure if it would be a noticeable difference but I was pleasantly surprised by how much it improved.

Works well but warranty is only 90 days where you can get a free replacement for a fault. After that you have to pay. With the touted 5 year warranty they give you a 10% credit to a new one.Your statutory rights in England is longer. Minimum 1 year for full refund/replacement and up to 6 years for faults.

Works well luckily I had a roll of gasket around, product description does state it comes with one. Would be nice if they corrected that like other buyers have stated otherwise product is great so far.

So fare this combustor seem to be good .

I purchased for a Blaze King Princess stove. Fit perfectly out of the box and made my stove much hotter and more efficient.Everything is included with the package and no need to buy extra tape for installation.
