I need some good advise before making any moves I might later regret and I think my reluctance on this topic is warranted. I've owned my home for about 5 years now and included in the purchase was a Harman Advance Pellet Stove. I have advocated to my friends how efficient it heats my home, at a fraction of what they are paying for oil, and so much easier than a wood burner from my childhood. I only burn quality pellets to reduce ash and take the stove entirely apart 1-2 times per season for a full cleaning of the accordion ducts, inspect burn plates (replace if needed), blow the dust out of the motors, lubricate moving parts, and vacuum inner panels and such. The start of this season the ignitor is not working so I think its the element and now the lower combustion motor started making some extra noise but a can of compressed air and some CRC lubricant and it's nearly back to quiet operation. Perhaps there's a brush in the motor that is wearing out? I've tried to remove the lower combustion blower motor but one of the pins is no longer fixed so it spins when you try loosen the bolt and no way to even grab it with pliers on the front side. I know there is probably a trick to removing this and if you can offer advice on how to remove that would be great but not the full intent of my post. 
You see, my father-in-law recently passed and he had his own pellet stove which I now own. It's an England 25PDV but I fear initially it may look like my Harman on the exterior but not act like it. Reading some of the complaints on this stove I cannot determine if it's from poor maintenance, bad installs, or a bigger quality issue of Korean made parts. My wife is thinking to replace the Harman with this newer 25PDV, but I'm not so sure I want to take the Harman out of main service to become my secondary in the basement. It's been steady and reliable for my 5 years and 5 years prior to me (purchased by original owner in 2000). Besides, to me the issues are minor because all parts tend to wear and are certainly replaceable. What would you do? Should I make the new stove my secondary or replace the 10 year old Harman?
