coldinnj said:To clarify: Not all the complaints on Harman are about the quality of the stoves but rather about some of the dealers. If I felt the quality was bad I would not have bought one. Also if a stove is being purchased used. Then the dealership may not be such an issue. Except for the blower most of these stoves have no mechanical / moving parts. Therefore if the metal smithing is done at a high standard and normal care is given there is no reason to "rebuild" a stove every few years. My coal furnace has not been rebuilt in over 30 years. All I have replaced so far is the blower motor (rebuilt the old one meanwhile), filters and the stack pipe (as I was too lazy to clean it out after the season and so the coal ash / acid ate it). So to simplify. A good quality used stove should be fine if inspected for abuse.
Engineering and understanding of thermal dynamics has not grown by leaps and bounds in the last 30 years. Albeit we have made improvements but measured ones for sure.
Remember the law of diminishing returns on your purchase.
The issues brought up here have mostly been with Harman pellet stoves. Which do in fact have many mechanical/moving parts as well as circuit boards.
