Thanks that is what I thought, it will come down to preference, however, efficiency has become important with the changes that we see. Mine burns clean with hard wood and this stove is enjoyable with less load maintenance which makes up for the other, so far. 10 to 12,000 is the cat manufactures recommendations, wonder if this would be under ideal conditions or average. You pushed yours a bit more; was it noticeable when replaced that it was time? What decrease in shoulder times/load did you get at the end?
This is the time of the season where I noted it changed a bit from last fall. When you have it at a good clip she is still burning clean and well but what is noted at the low setting could be occurring? If it is a slow constant degradation 18 years I would say may be pushing it a bit at 80,000 hours.
I have a spare cat in the basement as I knew this was a consumable when I bought the stove and we enjoy wood heat. Hope they do not have a short shelf life.
The vinegar bath how many more hours should you get on the cat if you go through this process, worth it? Knowing me I will slap the new one in and bath and cook the other, wrap and shelve it. Then when it is time to do it again I will say if your gonna do it might as well slap a new one in. For another couple of thousand hours (1/2 season) many be not.
Appreciate the responses. Here's your new tractor; no sorry we do not provide a maintenance schedule any more.
