24/7 here since about beginning of December.
Lat couple days near 40 or so, burn 2 full loads a day at these temps, or 3 splits at a time.
Since getting the EBT functional, and not having it open full time now, my wood usage has dropped, and burn times extended noticeably.
I can let it go 12-14 hrs plus and still have plenty of coals to get her ripping fairly quick again.
I have been babying the temp to stay around 650 tops, sometimes it will spike to 700ish, but very rarely. Since the fix, I have much better control with the air lever, and can actually almost dial in a temp to hold it at.
The internal corner door opening crack repairs are holding well. I did notice the other night, the face cracks are back. Not as bad, but still came back.
At this point, I don't feel it adds air to cause overfire or diminish the control of the burns, and feel it is not a danger, just a aesthetic bummer. Can't see em with the door closed though.
At some point, I'll have my neighbor come repair them again and see what happens.
I know drilling an hole in cast helps keep cracks from growing. Does the same hold true for plate steel?
I can prolly work some furnace cement in there. At this point, I really feel its a none performance issue.
If things get worse, I may be looking for a new replacement from PE.
I still love this insert. And since getting the EBT correctly hooked up & functioning, I really had to relearn the insert yet again.
When the EBT was out of place unconnected, I could shut the air down at 350 or 500 and it would still go where it wanted to go.....HOT.
Now if I cut it back too soon, she will either hold temp at there, or drop some. With the wet summer, the wood is not as good as I would prefer, but not green either.
I am really impressed at the control I now have since getting things right. The cracks bother me, but like a new car. Once the first few scratches happen and bum me out, after a while it doesn't matter anymore.
I still am very pleased with PE and their support and warranty backing, and the stove now is even better than I liked it before, prior to getting everything squared away.
I hate shutting it down, but if we get near 50, its going to burn out and not be restarted till it gets below 40 again.
