I am looking for specifications on this vintage 1920's hot water boiler system in my Sears home and was wondering if the information would be contained in either of the Sears homes books you mentioned to other inquiries?
Either a joint separated or my inner jacket cracked last year. The fix was simple and I haven't had any problems since, but I'd like to insure that I am getting peak efficiency.
FYI, the fix entailed closing the system, drainning, drilling and tapping a 3/8 NPT at the top of one of the returns and adding 3 containers of Radiator Stop Leak. Plugging with the 3/8 NPT plug, refilling & bleeding the system. :)
