Re: How to delete boiler coil and replace it with a HPWH
Good decision. As you can see, using a boiler for hot water results in a LOT of extra pipes and hassle.
If you are unsure of what can be hacked out of there, find a knowledgeable plumber to help you.
Re: Splitting existing forced hot water gas boiler into more zones
Thanks for all your input Ed!
I read the book.
I've decided that for this heating season I'll close down the dampers on the radiators in the main house, and run the zone off a sensor in the piano room.
Next season I plan on doing it the right way. Changing the setup to pump away, and adding a zone circulator for the piano room. That way future changes (hopefully radiant floor heat in the kitchen once a renovation happens) will be to a much more conventional system, without an oddball combination of zone valves and zone circulators.

Re: Hot water heater not working after boiler was cleaned
got it fixed, turns out the new circulator was working so I put another one on and flushed the system with 22 psi for about 10 minutes and that did the trick. Thanks for all the help.

You've been dealing with salesmen rather than techs. Where in Westchester County are you located? We might know someone………..

Re: Corroded connectors on new boiler.
OP the good news is that this is fixable. The bad news is that the company that made this indirect water heater went out of business on the 3rd. (it's not a boiler in your photo, and its a leak on the domestic side, so no boiler water involved with the leak)
It doesn't matter what language the people that made the pipe nipples speak, you can get a leak free connection there. These are generally regarded as good tanks, despite the company going under

Re: Corroded connectors on new boiler.
Leaks at transition fittings is part of the reason I use unions when connecting appliances. Typically, Propress x male or female. Expensive, but they save time if there's a leak and the next guy that has to service the equipment will thank you, even though you may no longer be in this world.
Re: Makeup water causing boiler failure due to thermal shock
My best answer to your question is "NO". (40+ years in the field). I did however one time see an H B Smith 4500 steam boiler lift off it's base, 3"-4" inches when a helper tried to drain that flooded off line and cold boiler. There were 2 other boilers that were carrying the steam load at that time. I would like to say that I remained calm but no, I did not. There was no boiler damage, just a lot of steam hammer.
I have seen quite a few melted cast iron sectional and steel fire tub boilers, and been in the room when 2 units in different boiler plants exploded due to fuel problems. One was an Erie City 20,000 lb/hr high pressure steam water tube boiler and the other was a small cast iron boiler. It is an experience that you never forget.
