Re: Heat loss calculation for rooms with high base temperature
You mix low and high mass radiant if you run a decent outdoor reset curve. With stable water temps, the emitter response becomes less of an issue.

Without a wiring diagram its a guess. You can't see everything in a picture.
Re: Cleaning a 130-year-old hydronic system before new boiler install - was it worth the 30+ hours?
I enjoyed reading this thread. I think the effort you made to clean your system will be worth it.
Unfortunately I think you will be disappointed once you start using that $500 delta T circulator. It's really doesn't work the way you think it should. No matter what mode you operate it in its never "variable speed" or modulating. It just cycles 100% on to 100% off. It doesn't vary the flow based on the delta T.

Might as well repair the consumption issue before a new boiler is installed.

Re: My SteamPunk boiler
If you lost a gallon of water from vents etc during an extremely mild month, I'd start working on that as it's likely why your boiler rotted out.
Obviously weather is different all over, but I haven't added water since last March or so.

Thank you for your question @masonnewb, and for your posts, @hot_rod .
Here is a drawing indicating how we would recommend wood boiler piping and wiring for a heating professional.

Re: Grateful for help recovering from rash changes to steam vent orifices!
After making sure main venting is sufficient I would start out thinking generally 4's for first floor, 5's for second and 6's for 3rd. Modify this by radiator size (and distance from main supply riser) such that small radiators on third floor drop to a 5, large or small radiators on second floor raise or lower to 6 and 4 and larger radiators on 1st floor bump up to 5's. This would be the starting point. Tune further with patience based upon room comfort level. In your own livable space on the third floor you could use adjustable valves like a Hoffman 1a to help your balancing. If using MoM vents you can also get a pack of orifices which essentially makes them adjustable.
