    That would be great but like you I have one foot out the door into retirement.

    It's not a trust issue, I just don't understand your statements and I feel like you aren't answering the question. Maybe I just didn't ask it right.

    Place a metal substrate combustor above a bunson burner. Place a ceramic substrate combustor next to it but over it's own bunson burner. Ignite a propane torch below each of them at the exact same moment.

    The metal substrate combustor will take right at 11-14 minutes to hit 550F.

    The ceramic substrate combustor will take 20-25 minutes to hit 550F.

    The M28R, as of 2015, requires the filter train to be pulled at 60 minutes. 100% of the time, the first hour PM levels are lower with a metal combustor than the ceramic combustor. Has NOTHING to due with integrity, warranty, price or anything else.

    It is all about PASSING the test.

    That makes more sense. Here I was thinking we were talking about running the catalysts in an actual stove. Not just on a bench over a bunson burner.

    Thank you BKVP

    Same thing happens to combustors in an actual stove.

    Well, believe what you want and go with that over truthful informed and EXPERIENCED data.

    You write "us", but no one else questions full disclosure, honest responses. Your fear of being lied to has put you into the mindset that you are being lied to all the time. That is most unfortunate because every single post on this site and others where I share very truthful information, you the same way. Either you believe or you don't, I can't fix that.

    But what I do have is my integrity, 30 years experience with the leading company (and working with suppliers) in catalytic technology and a willingness to put up with pushback. But fear is not data. The data exists and I openly share it.

    Update to this thread regarding an alteration to my install of a 6" chimney on the BK40

    As many on this forum already know, I'd been battling a random stale smoke smell for the last two months. If you'd like to catch up on that and the resolution, read it here:
    Blaze King 40 Smoke Smell Near Stove (No Visible Smoke) on Low Burn

    So, while troubleshooting the smoke smell issue, one of the things I did, at the advice of some on here, I actually added an additional 3 feet of pipe to my chimney. Holy cow!!! Amazing difference in the stoves performance, and I thought it worked great before this change! Without moving my thermostat from my usual burning position, the stove completely changed it's behavior. immediately, coals began to glow brighter, and most amazing, within 4-5 hours, the glass had cleared off to almost clear except for a bit along the sides. The addition of pipe took me to just over 22'. Wish I had done this from the start.

    Even though this stove works on a 6" pipe for me, I'd still go with, and recommend going with a 8" stove for the BK40 if installing a new chimney. I was happy with the performance on my existing 6" chimney, and even happier with it now that it has the extension. But, I can definitely see where an 8" could have it's obvious advantages. was add an additional 3' of 6" pipe to my existing chimney. This did nothing to resolve the smoke smell addressed above, but holy cow, what a noticeable improvement in draft!!

    Well, the chimney is the engine that powers the stove...put a V6 in a fullsize truck, meh, it works...but go with a V8, now we're talking!

    Yeah but if they change the test to include the first hour of emissions wouldn’t the hybrids have an advantage over a true cat stove that need to be in bypass mode for part of that first hour?

    Not necessarily. Study emissions reports and some hybrids do better than others, but straight cat stoves still have better emissions and efficiency.

    Todd,

    I should have also mentioned that EPA could implement an exceedance metric. I know first hand that EPA does not like the 1st hour filter pull as a way to evaluate a wood heaters overall performance. Quoting a senior engineer I was speaking with "the first hour doesn't paint a good picture of the overall performance of a wood heater."

    When I then asked, what other exceedance metric could the agency be considering, the same guy responded, sustained PM (particulate matter) over a specific duration of time. So, in other words, it the PM were to exceed a specific level and show no signs of decreasing (cleaning up), then it may not get certified.

    For real! EPA acts like America is the ONLY contributor to global "pollution".

    Truthfully, there are folks out there that don't care about even trying to burn clean. They burn trash and other items they shouldn't burn and they don't care that the neighbor 60 ft away has asthma. In my 30 years in the industry and working with EPA, I have learned they react to the pressures of State regulators. Candidly, EPA has much bigger projects to deal with. But States sue them to act!

    One thing that occurs to those that contemplate the advances made in emissions reductions in wood heaters, regulation made it happen. Our company went from making 80 g/hr stoves to stoves below 2 g/hr, some below 1 g/hr. Regulations have "pushed" innovation and manufacturers have acknowledged this fact.

    But when it clean clean enough? Does the increased R&D, engineering and testing costs, translating to more expensive wood stoves, serve as a disincentive to replacing older wood heaters...darn right it does!

    So much so that the government had to subsidize/incentives it with tax credits. Probably why I still have an old black box.

    Exactly...we are well past that point IMO...getting diminishing returns now, big time!
    The stove regulations in the 80s :yes:
    Even maybe up to 2017, when they included wood furnaces :yes:
    But now, now it's more like just someone's agenda.
    If they want to do something productive, figure out how to get the big polluters on the other end of the jet stream to even halfway comply!
    It's a lot like regulating how much the goldfish on one side of the bowl can poop, but not the fish on the other side.

    Yeah used wood stoves around here are going at a premium! Many people will not dish out $4-5k on a higher end stove. Homemade stoves and barrel stove kits are making a comeback as well. It’s almost like the EPA is taking baby steps to just do away with wood burning.
