Hello all, I had purchased a Central Boiler Wood Furnace in 2003 and it is burned out already. The company told me that I must of burned trash in it at one point and it started the corrosion process. I know other owners of Central Boilers and other brands of out door wood furnaces that have had units for over 10 years and they burn tires, telephone poles, and railroad ties (of which I didn't) and theirs are still in good shape. I suspect Central Boiler changed their metal supplier that year and have had to do a lot of warranty work, and they are hiding from something. Has anyone else had simular experiences?
