Harman sent another stainless burnpot to my dealer for me to test. This one is a tad different than the last one, it has larger holes drilled in the burn surface. I will post updates to how it performs.

I don't know, Wil, what does this make, your 10th?
My top baffle plate is buckling in the middle, should not, the
way it is constructed....
Wish I had my own gas well!!

A bubble formed on the first stainless burnpot that I had prior to cracking between three holes. The stainless burnpot that is now installed has larger holes, time will tell.Bill B said:
I've had this burnpot in for around 4 days, haven't checked it yet.Bill B said:
I've had burnpots start to form a bubble after a couple of weeks of burning, I even had one that a small bubble formed after 3 days of burning, others 3 months, no set amount of time or quanity of pellets burned.
Wil,
For your sanity, I sure hope this is the ticket for you. I don't know about you, but I would have pulled out my hair by now!
I'll keep my fingers crossed for you!

Wil,
Do you put a new flame guide and insulator on while you are swapping out burnpots? If not how long have they been lasting before wearing out and needing to be replaced?

No, I'm on my fourth year burning with the original insulator and flame guide. The insulator is getting a little ragged, spoke to my dealer about it and he said don't worry about it, it's the norm. My flame guide is made of cast iron, unless it cracks, I see no reason to ever replace it.Pellet_Dog said:
I paid $4700.00 for my boiler. The reason I would do it again even though I've had issues with burnpot failers, my dealer and Harman have been making efforts, no costs to me, to try to resolve the burnpot bubble issue. I'm in hopes that the issue will soon be resolved because I really like the boiler.Pel_Don said:
I paid $3500 for mine, second hand. and yes I would do it again. Harman has been good so far with replacement parts.
Even though I have also had the same burnpot issue as others (2.5 years old with 3 burnpots replaced) I would also buy another PB-105. Yes, my Harman dealer has been very easy to work with but besides that the thing is a piece of cake to clean. I can thoroughly clean it, including the burnpot, tubes, and draft motor/fan in less than an hour. Interestingly, I installed the current burnpot last spring and it is just now starting to show a very slight bubble. Like Wil mentioned, I had one that started to bubble after a month or so. It is almost like they have been experimenting with different burnpot metals all along. Anyway, I am very happy with the boiler.
I do not own a 105 so take my comments with a grain of salt.
From what I understand, cold air is coming through the burnpot to the fire within it, From an engineering point of view, it sounds like the massive temperature difference between the top and the bottom is causing enormous stresses in the steel and subsequent warping. The solution may be in layering with very small air gaps between t he layers in order to mitigate the temperature differences.. Has Harmon tried that?
IF any dealer is reading this, ask them. If it works, then I want a free boiler.....and a Mercedes....and a Porsche......
