We hope to do some more testing later this fall with really high and really low quality pellets to see how much emissions, efficiency and maintenance are impacted on these stoves. John
Hi, first I'd like to say thank you for your time and advices
I was amazed with all of the detail info you came out with the test you made on pellets stove, but only after looking at the picture in the
Background and Testing Details, I stop reading it, I found out that this was probably not much of a scientist test. Please my advice would be; first, you should get knowledgeable people from each company or at least basic knowledge so that all stove would be set properly prior of making such test. Just by looking at the picture bellow, I can assure you,... that the Piazzetta was not set properly,
none of my customers stove would get that ash sponge like on the picture unless I want to, oh! I did fund some on this forum, pore customers.... they had their stove delivered but not installed and neither adjusted just on Hearth forum you will find many post that I have interfered in for that same issue. The result you are getting on this picture is due to a bad settings of Program 3 and 12 called ‘’auto cleaning’’ cleaning intervals and cleaning time, also by a lack of air from program P16 to P22. I can reproduce this problem or ash sponge, on demand with any Piazzetta stove with in a period of 24 hrs if the stove is not set properly. If you ever want to make a better test with a Piazzetta, and don’t know who to turn to, call me, you should get something very different as a result. The Piazzetta stove are one of the rare stoves that as a fully adjustable combustion fan, from 1000 to 3000 rpm at every level, and this make all the difference, but you need the knowledge to set this stove. I’m sure that Ravelli would also have score better. Can’t say much for the other stoves they have almost no adjustments. And by the way, I own a P962, and I almost never clean the grate but I need to empty the ashtray every 5 to 6 days, again, once set up properly.
and please dont get me wrong, I'm not saying that you are not professional but just that you do not know, like many people, how to adjust all the parameters that a Piazzetta offers.
