Apples to Oranges,,,

NG is not as hot a flame as oil, so that`s a factor(not in his favor), but

did he perform any kind of H/L for the units as they are now?

Perhaps you don`t need to satisfy HUGE rads completely across all the sections to meet the load requirements nowadays, if it`s an "old system" building upgrades definitely reduce the needed load,,, but again, that can ONLY be calculated by a proper H/Loss room by room.

Tricky stuff if you play-it that way,,,, but it is accurate!
