Looking over existing steam system
Bought new house, looking over the existing one pipe steam system. Very satisfied owner of 'We've got steam heat!' and 'Greening Steam' . After reading both books I've noticed several things about my steam system that aren't quite up to spec.
It appears this "Steam Main" is a Vent:
My regular steam main is hooked up to cast iron, but the wet return is copper (which I think is OK):
However, it is flush to the floor, which might make it moderately difficult to insulate:
I've also noticed my supply lines are copper and not steel and as per my reading they can't flex with the pressure steam gives out. I can't seem to find the skim tap either:
Already cranked the pressuretrol down to .5 with a differential of one, I don't see the water surging that much. The boiler dates to 03/2000, Burnham Boiler Model: SIN4LNCP-LE2
Any other general best practices are welcome.
