Hopefully i did this right and the pic shows up it is a sears automatic heater that is what it says on the label I believe it was originally a steam boiler the model is C1D71
I am just looking for a rough guess on the age I believe they are going to replace it.
Was there a serial number?
If that boiler was on ebay it would probably be titled atomic age
I’s just a gas furnace, not a boiler.
As I recall those were fairly old when I worked on them before I retired 16 years ago. (Anyway they looked exactly like the one in the picture.)
