As I said in another post, I'm looking at a 1980's model Appalachain freestanding/insert for $500 (comes w/ a huge hearth pad thing). I was wondering about how stoves "age." What about a stove would likely be in disrepair after two decades? How big a deal is replacing any of these parts? The cast iron (I believe it's cast iron) is sound with a little surface rust so I was wondering what else to look at that might be serious. It's located in a storage building w/ no electric, so we can't try the blower but I figure at worst we could repair/buy a new one if we need it. In my simple little mind I see it about like cars - the earlier models are still simple and easy to fix. The newer, high tech models don't age as gracefully, though they may be more effecient. Any thoughts??
