Re: Weil-McLain Ultra 230 Lockout – High Supply Temp
That piping and wiring is atrocious. Not exactly closely spaced Tee's there.
I can't find the PRV, but find a way from it, to the boiler. The boiler is air locked and must be purged. If you need to raise the weight on the Flo valve and purge backwards, so be it. You could also slowly introduce domestic cold from the drain on the bottom of the boiler and find and easy loop to purge through.

(and the corrosion inhibitors in ann arbor water will form nodules on monel just like they do on any other metal)

Re: steam vs vapor system
Try Dwyer. They have quite a variety (to put it mildly) and there are a few which might suit. They aren't cheap…
Re: steam vs vapor system
find an nos honeywell with a mercury switch?
keep the pressuretrol as a secondary safety set to maybe 2 or 3 psig

Re: Go To Pex Brand For In Floor Radiant
I'm going to run against the grain on this. While Uponor and Rehau are great, all PEX has to meet the same standards. There are some differences in the flexibility and the location of the EVOH layer (some of the cheaper stuff has it on the outside so it can become sticky and make noise in underfloor type applications), but from an actual performance and longevity perspective, I have honestly seen more failures with Uponor tubing than all the rest combined- including the cheapo Rifeng/Riifo stuff. Nobody carries Rehau in my area anymore so I don't see a lot of it, but have never seen a failure yet. I do find Rehau to be the most flexible, if that's of any concern. With that said, I have personally installed hundreds of miles of the Rifeng based "junk" and it has been absolutely flawless- spending 3x the money for He-Pex doesn't make any sense in my opinion unless being able to see the pretty pink glycol in the lines is of concern. Fittings are another story; Uponor or or nothing, but the tubing is subpar at best in my opinion.

Re: When did pressure relief valves become standard?
What year did Hartford Insurance debut their little piping contraption? The LWCO must've been after that, right? Not sure about the relief valve, but I'm glad someone thought of it. I've seen video of a Fulton 100 psi boiler go off like a rocket.

Re: sight glass issue
There is no auto feeder. My untrained guess is #3 as well. Since I've shut off the ball valves into and out of the coil, If the level does not rise tomorrow, would my guess be correct that the coil is the likely culprit? How else can I be sure?
