I didn't realize that Garn boilers could also burn corn cobs, but according to the manual, you can. Has anyone ever burned cobs in a Garn before? I'd love to be able to get feedback about how it compares to wood. I need 2 knee replacements and I just can't slug wood like I used to be able to. I have no idea how much you would burn in a season, or how much corn cobs even cost....but if wood keeps going up (and it will be because no one can afford to heat their homes with anything else nowadays.) I'm wondering if it might be worth looking into. Storage and loading might be a PITA...I'd have to put some thought into that....but it would still be one heck of a lot less work than wood! Just curious! Thanks! Patti
