I haven't been on here for a long while . I fact I haven't burned wood in 3 or4 years. I boiler sprung a leak and haven't bothered to fix it but I am going to retire and hope to have time to cut wood again and burn. I know some have tried to patch these Pro Fab stoves. I wonder how that worked out. I really liked that boiler. I had a contact before but the phone number has changed for a gentleman in New York that patch his. Has anyone had luck with the heavy duty boiler stop leak Thanks Jim
