When the system was installed 75 years ago, it was a wood and coal system. Manufactured gas was available, but mostly used for lighting and cooking. Oil came in the 50’s. Wood and coal took such a long time to bring the boiler to heat that is could be adjusted by the fire size. The newer burners and boilers steam faster, so quickly over-run when the Hartford Loop is missing. Dead men tell no tales, especially to new plumbers. Old-Timers keep the information flowing.
