Totally agree in terms of the fridge concept. Corrosion on the the other hand is discriminate.I used to think if stoves as “forever” items, before I was a real wood burner, similar to the way I thought of appliances when I was a child. But now I realize the tech changes quickly enough, and all of the working parts and gaskets take enough abuse over the course of a decade or two of full-time burning, that I’ve changed my perspective. Stoves are consumable, like the modern refrigerator or range. Use them 15 years, and then replace them with something far better. Building an expensive and weighty tank with a shell that will vastly outlast the working components within, or their relevance with regard to current emissions targets, is not likely the best path for any manufacturer trying to compete in a market with any cost sensitivity.
So there may be stoves out there with thicker shells than my BKs, but I don’t think I care. They generally don’t perform as well as the BK today, and will almost surely fall even shorter in comparison to the new ca.2030 BKs with which I’ll replace these, after fifteen years of full-time use and 150 cords thru the pair. Likewise, my mom has a 1953 GE fridge, and can brag it lasted longer than my last three refrigerators combined, but it uses 6x more electricity and has fewer conveniences than any of my more modern variants.
