Re: Pex sizing
Join a wood boiler forum or group and you will see literally thousands of people who have had problems with DIY or drain tile type underground lines. Every single one of them is problematic in some way or another. There is no excuse not to just buy the good stuff right away because you WILL end up buying it down the road anyway and have to dig your yard up a second time.

Re: Splitting existing forced hot water gas boiler into more zones
A mono flow system should have its own circulator . Never zone valves and balances valves …

Re: Boiler short cycling?
This failure in the first video and around time stamp 6:23 on the second video remind me of a flame proving signal being lost. More than likely there is a ground path failure in the Flame Rectification path from the UTEC ignition control thru the flame back the the UTEC control That is common when a burner is connected to the rest of the boiler the way your burners are fitted. To be sure the ground path from the burner to the UTEC control is not corroded or compromised I run a physical ground wire from the pilot burner to the GND (BURNER) terminal of the UTEC Control.
Here is an illustration of the wire in place
This wire will eliminate any fault with the ground connection present from the burner to the control
Re: Trade school curriculums - how could they be better?
a good friend was a teacher at a community technical college for many years, solar and hydronics
Before he retired a few years back he noted a majority of the 1st year students could not solve a basis math problem. That makes for a steep hill to climb for plumbing and heating students. Maybe some better testing and prerequisites

Re: Controls Upgrade (1960's AmStan GPM boiler)
you need to determine if the wall thermostat is turning it off or the boiler control

Re: Baffled: Weil-Mclain startup and delay on break relay
@EBEBRATT-Ed Nothing wrong with that. I get it, protect the expensive stuff with the inexpensive stuff (and I have done that too). And often isolation can be a benefit, relays and opto-coulplers are used all the time.
In this case (specifically) a relay would be one way to solve the timer's minimum latch current issue. The need for extra protection of the timer is minimal IMO.
It seems many folks have oversized boilers and if there is an easy, inexpensive (maybe foolproof) way to minimize the short cycling situation I think that would be benefit to add to the system. However, I would venture to say most folks that have oversized boilers have very little electrical experience, so the simpler it is to add a timer device and have it work correctly the better. Many timers and pressure switches are out there, but they would be more complicated than a two wire installation.
Folks could add an EcoSteam ES-25 like product (if you still can find one) or other PLC based control and have fun with that adventure but that is more expensive and more complicated.
In general I like to keep it as uncomplicated as possible. More stuff there is, the more there is to fail (and then figure out) when you need heat.
It just seems to me as time goes on and HVAC controls have become more complicated there has been more problems and possibly less competent folks to repair them.

Re: Peerless steam header height
you can take the jacket off if you are really tight for space moving it in and just move the raw ci block. if you don't have enough height for the header in the installed position you can do a drop header

Re: What can you tell me about this old Weil-Mclain E 5 B boiler?
I'm not sure I want to see the rest of it. Find a reputable service company and get a full evaluation. Hope for the best, prepare for the worst. Even the thermostat is freaking me out.
That hole in the flue that's completely disconnected is a combustion test port. A port that shouldn't be there because the boiler has a draft hood.

Re: how much does size matter in feet?
How are you sure that it's an open tank, @scatgo ? I sounds to me like a regular steel compression tank.
