Re: How long is a steam radiator supposed to stay on before cycling?
A radiator — one pipe or two doesn't matter — will continue to make heat as long as the boiler stays on. It will only stop when the boiler stops
What happens on one pipe is that when the vent closes the air is out, but steam will keep coming in and condensing as long as the boiler runs. The only way you can stop it from heating is before the boiler starts — if you close the vent then, it simply won't heat up.
It would seem that your building's boiler is just staying on…

turn the valve off completely instead of relying on the air vent or screw in a TRV with an integral vacuum breaker like this one:

Re: My steam boiler water got a little contaminated, so what can we learn?
It sounds like we both agree that lower isn’t good and this is why I don’t like people relying on auto-feeders. They spend too much time at lower levels
Totally agree with that.

Re: Wiring Weil-McLain AquaPlus to a Taco SR503-5
For DHW priority.
Red on the aquastat to R Zone 1 (priority) on the zone panel.
White on the aquastat to W Zone 1 (priority) on the zone panel.
Yellow on the aquastat (AC1) to Zone 1 (priority) C on the zone panel. (AC1 shows it as the grounded side)
Green on the aquastat (AC2) to R on the zone panel.
Enable the priority, the switch array on the Right hand side.
Connect the Main X-X and Priority X-X (DHW) End Switch terminals to the appropriate place on the boiler.
Connect the heating zones to Zone 2 and Zone 3.
Make sure the circulators are wired appropriately.

Re: Honeywell Help
@Melby More pictures and more clarity and information, boiler make and model about your present issues may help us help you. The thing you call a spring is a Relay.
When the thermostat circuit closes TV to T that puts 24 VAC across W and T (the relay coil of 1K). Relay contacts 1K1 close energizing the circulator (120VAC), contacts 1K2, 1K3 close enabling the burner (24 VAC circuit).
@HomerJSmith if you like repairing Aquastats, next time consider this. Desolder the relay solder joints, unfold the pins so they are vertical (or perpendicular to the circuit board) wrap thermostat wire (or the like) around each pin snugly and extend it at least about 1/2" onto the circuit board and solder it all securely. The added copper wire will make the solder joint must more robust.

Re: My steam boiler water got a little contaminated, so what can we learn?
"And yes I think the upper inside of the sections is getting constantly bathed in boiling water…that is the point."
So if the point of a higher water level is for the upper surface to run "cooler", that would be measurable, yes? An infrared thermometer should be able to pick it up. My bet is, once the water is boiling and steam is being produced, there will not be any difference.
"So my question is why aren't you running your water level higher?"
Mine has been at the recommended water level (it's clearly marked on the front of the boiler) once the mistake was understood.

Re: Good Protocol For Keeping Water Clean in Boiler
Since I replaced the return piping below the witer line with copper, I'm just not seeing a lot of dirt and sediment in my boiler. I see a little when I drain it for the summer, but in the heating season I only add a little water. I never need to drain it. I haven't used my handy-dandy gauge glass blow-down valve in a couple of years.
Does dirty water make it harder to boil? I think sedimentation might impede heat transfer to some exteent, sending more heat up the flue, but I don't think it raises the boiling point. Dissolved solids (e.g. minerals) can elevate the boiling point, but not suspended particles or colloids if I remember my chemistry.
Re: Good Protocol For Keeping Water Clean in Boiler
Since this thread got reanimated, I will take this opportunity to share a video I made the other day about this topic. It shows my current practice to keep my boiler water clean and to minimize corrosion
Re: Good Protocol For Keeping Water Clean in Boiler
Adding in some questions here as it ties in to a situation I have. Appears I've finally located most if not all leaks in my one pipe system. Make up water has been reduced to very little (about a quart over 2 weeks of pretty cold weather here). So I'm in the situation where my boiler water is pretty dirty, likely from the make up water added in the past. Is there any option on getting the water cleaner without draining and flushing the system? Doesn't appear so, my plan once the heating season is over was to flush out the entire system including the inside of the boiler and return lines.
Would adding 8 Way be something done at the same time I replenish the system after flushing it down? BTW Peerless boiler replaced in late 2011.
