Question 1: "Is this burn in the video the same as before the Regency rep tweaked the insert, or better now?"
Here is a video of the burn before the Regency rep closed up the air leaks with extra gasket. It is hard for me to tell a difference in the control of the fire between before the air leaks were sealed and after, to be honest. Unfortunately, it seems approximately the same as before.
Question 2: "Was the wood put on a large, hot coal bed?"
Yes I would say so. From videos of other wood stoves, I would still have hoped for more control over the fire than I have. See the YouTube video I linked at the bottom of this post. She seems to start with a nice bed of coals, loads it up, has a fire going like I had, and then is able to really control the fire by closing her air intake completely.
Comment: "If the issues around the door sealing can't be resolved..."
The Regency rep did a temporary fix (the permanent fix is a new stove) which seems to have resolved the door sealing for now. Here is a picture of how he added gasket to close up the air leaks to temporarily have the stove work better until the new stove arrives. The bottom right is doubled up. When I do the dollar bill test now the door seems to seal. The smoke test around the glass also looks good so I don't know of any air leaks at this point. So the video I posted last time was with the air leaks sealed up.
I was hoping for an experience more like this lady has in the video (linked below). She gets the fire going like crazy, shuts it all the way down, then is able to have it burning mostly off secondaries. At 4:29 she shuts the door with the air intake all the way open. Her fire at that point (with the door shut but the damper all the way OPEN) looks like my fire does when my door is shut and the air intake is completely SHUT. Honestly she has a HUGE difference between the air intake all the way open and the air intake all the way shut (compare 4:29 to the end of her video). The difference in my fire between the air intake all the way open and all the way shut is very difficult to tell the difference. If it is normal for my stove to not have that kind of control and barely a perceptible difference between the air intake open and the air intake shut, then maybe there is another stove that would work better? I'm still a little hopeful that a brand new stove would have more control, but I'm nervous to get my hopes up too much because I have been disappointed so many times over the past year.
Comment: "I'm sorry this has been a rough experience. The vice grip door handle is classic."
I am so thankful for your sympathy and your feedback - you don't even know! It is an encouragement to me when so much of this experience has been discouraging. A bright spot
. The Regency rep actually replaced the door handle, but I can't use it because so much force is require to open my door that the handle could not stand up to the force required to open it!
