Talking about the boiler not the radiator. Label plate says you're rated max is 25 psig steam and 50 HW? I'd find the safety relief and ensure its not scaled-up if your running with an unreliable aquastat or pressure control.

I looked; nothing. In fact the public water comes through a copper pipe and Regulator, then converts to Iron for Automatic fill for Top-Off if some one goes around to bleed the upstairs radiators. A lot of cast iron radiators in this home....1919 home.
