I've been using a pellet stove for the past few winters and after this winter the thing is coming out!
Reason: too noisy. Sure, the fans (there are two of them not counting the small fan for the auger) don't make that much noise but when they run 24/7 the noise pollution gets to you. Also, the stove dries out the air and plays havoc with sinuses and mucus membranes around the eyes. Pellets were once easy to obtain but now that more pellet stoves are being used in the States, guess where the shipments of Canadian pellets are headed. The quality of the pellets varies too. The recommended length is no more than 3/4in but in the last bag I opened they were as long as 2in. Arching of pellets over the auger can cause problems of uneven feed and consequently inregular burn.
