Need pictures of the near boiler piping from a distance.

Take a picture of the pressuretrol (pressure control box on the front of the boiler) When is the last time the pigtail (siphon loop, usually steel or brass under the pressuretrol) was cleaned?

see photo
s…..i have since insulated the pipes …….

Pressuretrol seems set correctly assuming the dial inside is at the lowest setting of 1. Definitiely as mentioned clean that pigtail if you haven't already. If it is dirty or blocked the pressuretrol will not sense the true pressure in the boiler allowing pressure to rise higher than settings.
Did this problem just develop recently? What do you have for a main vent and is it working?

in the 1st picture what the steel pipe on the right that’s capped off? Can you get a pic of that side?

Go in the basement and watch a cycle. When steam reaches the header and starts travelling down the main (you can feel it through the pipes, won't be able to keep your finger on it) you should be able to tell if the main vent is releasing air. You can listen, feel or use a visual such as match/candle smoke or hanging a thin strip of paper towel above the vent. If you just can't tell then take the vent off and while holding it upright blow through the bottom. Should be able to blow air through it.
Have long is your main and what size pipe?
Have you checked the boiler size vs your connected radiator EDR?

Why and how much do you turn the thermostat down each night? Steam radiant heat works best by maintaining a consistent setpoint.

Not practical for many.

example….i may put down to 68 at night….then first thing in morning….i will put to 70 or even 71 (old 3 story 100 year old house! — no insulation in walls!).

Is your stat programmable? Can you start your recovery earlier and break it up into some 30min on off steps? House will keep heating during the off steps.

Doesn't anyone see a problem with this piping?
I think maybe 1-1/2". copper risers going to 2" mains might be a reason for getting wet steam into the mains, but maybe it's just me!
I can only guess at the pipe sizes from the picture but I believe this is what is going on under that insulation.
The installer followed the manufacturer's piping arrangement perfectly, but the manufacturer does not tell you how to connect to the rest of the system. You need some common sense for that. 1'1/2" copper is not the right choice in my opinion. I thins at least 2" for good measure, and I might choose iron/steel pipe and fittings over copper. But that's just me.

After you make that expensive repair and you still have the same problem, What will you check next?

Supplies shouldn't be smaller than the mains they're feeding. 😬
Trying to squeeze the best out of a Weil-McLain JB-5 running a 1912 1 pipe system.0 -
another photo…..so the problem is the copper going into the steel at the top?

Give them a break he only had 1 1/2" on the truck😊
How is the boiler water level when the boiler is steaming? Does it stay rock steady? Move up and down gently total movement under an inch? Or bounce up and down violently?

OK I take it back, It looks like that copper is 2" and that is the full size of the connected mains. It just looks much smaller in the first photo.
NEVERMIND
