That stands for Unidentified Roof Object.
Anyone want to take a guess.?
It will be good as mine.

Looks like what left of an old heat exchanger for a water tower heater??

The tank is most likely a condensate return tank from the boiler. Here in Ga. it is uncommon that boilers are used for heat but I have seen this in industrial application's

Expansion tank for the heating system. Open type.

Chimney was at least 30 feet from there
