I was talking with the neighbor the other evening while we both out moving snow. He put in a pellet stove about ten years ago after suffering a chimney fire with his wood stove (he has had a history of misadventure that way)
With insurance money to have the replacement pellet stove installed properly, he got a high end (quad fire?) and a lined chimney.
He likes the pellets well enough, and though he gets the dealer (reputable) to service the system every spring, he can't seem to keep ignitors in the thing. He is on his second one this season already. Plus the auto ignition is spotty at best.
He is at the point of cleaning the combustion basket every evening after coming home from work. The stove is shut down and allowed to cool, then it's a bristle brush and a hooked pick to get all the holes in the basket cleared out.
The ignitors are not costly, $30 IIRC, but installation is laborsome by his account.
The entire conversation has turned me against putting in a pellet burner to replace the 40 year old Fisher log wood stove that has served without fault. (Other than burning lots of wood! ;-)
