Check to make sure your radiators will work with HW, otherwise you will have to replace them.
Also, make sure they will provide enough heat on HW. On steam, each square foot EDR will give off 240 BTU; on HW, only 150 BTU.
And since HW runs at pressures maybe 10 times higher than steam, converting them might make them leak.
Several reasons we don't convert steam to HW.

And why, oh why, would you be wanting to ditch the steam for hot water? If the old steam boiler gives out — replace it. And in the meantime do the minor repairs to bring your steam system up to snuff.
You'll be a lot happier… and will spend about half as much money…

outdated? i don't think there was ever time that it was the right solution to a problem…
Re: Thoughts on brass bushings and plugs
As I said above, if this system is steam, then PEX simply cannot be used. Anywhere. Whether it's a stub, a through pipe, whatever. Doesn't matter. PEX cannot withstand steam temperatures and it will fail.
Re: hydronicshop.com
I prefer to get everything at the same place. Finding a deal for one or two items at one place and another deal at another place and so on… then needing to purchase everything else at another place is just time consuming. Get the best deal at a one stop local supplier is less expensive in the long run. I had better things to do with my time, like getting the actual work completed.

Re: NJ Boiler replacement decision points...
So I used 55° incoming water temperature, raised to 110, which is about as hot as you could run to a faucet. You could go online and determine the city water temperature high and low probably.
Wintertime water in Phoenix runs around 80°, in Milwaukee down to 35- 37° in above ground water towers.
The only way to get 90% plus is if the boiler is running a low temperature 130 or lower so it condenses. What temperature do you run the Munchkin?
Since the boiler kicks up to 180° for hot water production, 85-87% efficience in that mode.
With a combi the boiler heats water instantly, so no need to calculate gallon like an indirect.
At a 3 gpm flow it could run now until the end of time and produce 110° hot water. It works much like a tankless water heater.

Re: Ignition transformer insulation (Navien)
Item 19, Flame Rod, shows it comes with the gasket. They should supply 10 with every Flame Rod because they fall apart if you breathe on them.
