I am somewhat new to pellet stoves. Until last year, I heated with wood (for 40 years). So, a little bit of a learning curve. I bought a US King pellet stove last year at Tractor Supply. Model 5502M. It has worked much better then I expected. No problems once I got used to cleaning it once a week. Well, no issues except it does not work well if put put on the lowest heat setting. I am now looking at getting another. One for in the house and one in a barn. I went back to Tractor Supply and now they are selling a model KP130 stove. It looks near the same as the 5502M. My plan was to have two stoves the same model. This way, I might get some spare parts to have on hand in case something fails. Now - with two different models - I have no idea what parts fit both? I am worried that in a few years, no new parts will be available. I called the company and so far - even they do not seem to know. Also no PDF manuals to be found so far for the newer KP130. For the 5502M, yes. Considering I got no answer so far from the company, I wonder if they actually design it here, or let the Chinese do it?
