I came across an old boiler I thought I might be able to use to heat my house. I am building a 2500 sq. ft. house and will have radiant heat in the entire basement and first floor. I have a geo system designed but have access to a lot of wood and wanted to get an old boiler like this one to put outside under a roof of some sort where I can chop wood and load it up in winter. To me (no experience with boilers) this looks like a old tank that was built to last and probably would work great. My question for you (veteran plumber with experience) is would I be making a mistake here? Are these things prone to rotting out or something else? Also can anyone tell me more about this unit, I could find very little info when I searched online.
