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.

How do you know it’s vastly undersized?
That would be a 1st!

Re: Steam Near Boiler Piping
steam is only ~212f, nowhere near hot enough to burn wood. the pipe just needs enough clearance to move without making noise.
i can't tell for certain in those pictures but it looks more like rot than char
Re: Steam Near Boiler Piping
I agree with that, except there will be very little liquid water in there and it probably won't even flow, it will either get pushed on down the main, or it will re-vaporize. There will be a little more on startup when the pipes are heating up. No biggie.
Re: New garage radiant floor
knowing the heat load would be helpful. Typically .50-.65 gpm for 1/2” loops
If it is down in the 20,000 range a tank type water heater could be an option.
If it is just a hand sink a small under counter 6-10 gallon 120v tank may enough
Smallest mid con is 50,000, smallest combi around 110,000. Both would turndown to 8-10,000 btu:hr
Is cost the determining factor? A mod con would be the most efficient option

Re: What can you tell me about this old Weil-Mclain E 5 B boiler?
Don't know what the duct tape is all about but it shouldn't be there and the flue pipe is falling apart with the joint in the second picture almost open. Really should not run this the way it is . Need a good tech to check it out (if one exists).
Post the city and check "find a contractor " on this site.
Re: steam radiators are hissing loudly and spraying hot water/steam
Piping does not look bad. Water might need a good cleaning for starts
