Wow my head is spinning! I have been trying to figure out the differences and the similarities between different Class A Chimney systems.
The typically specified system offered through my dealer is MetalFab and everything I've ever read really seems super good. It is rated as UL 103HT with an advertised "Continuous Operating Temperature" of 1000F.
But, I've also read thread after thread and THINK (trying to emphasize my extreme doubt in this newly known knowledge of mine!) average temperatures in these Class A Chimneys are around 600 to 750 degrees F (actual inside temps not temps from some surface thermometer). I've also read and THINK (same emphasis on overall doubt) highish temperatures in these chimneys are 800 to 1000 degrees F. Seems that some folks purposely push to 1000F when they are trying to "clean the creosote out".
If this is all halfway accurate I'd like to ask about the benefits (if any) of opting for a chimney system (such as Excell's) where they advertise "Continuous Operating Temperature" of 1200F and they are both UL 103HT as well as ULC S629. How should that factor towards making a product and purchase decision? I also see some specific manufacturers advertise additional tests that they seem to do themselves (such as Simpson's timed tests at various very high temps). How should those tests factor? As I may have mentioned in other threads our dealer is super sharp and although he really likes the line that MetalFab makes he's also agreeable to putting whatever we want (as long as its also listed as acceptable in Regency's info) in there so now's the time to think these things through. With a small sized steel stove like the Regency CS1200 is the 200F degree difference ever even going to matter much? If we ever wanted to put a super large stove in would it matter much then?
Thanks for all the advice; I'm trying to search out most of my own answers here (and I've absolutely learned so much stuff) but sometimes it helps to have another thread as long as I didn't miss one out there already addressing this specific thing? Thanks Again!
