Re: Bell & Gossett Circulator
The expansion tank is on the system side of the prv which is correct in itself. It should be positioned such that the circulator it pumping away from where it connects to the system.

Re: Professional opinions please
I would like to take full credit @Intplm. However this is the OP's drawing with some modifications. I find that using the original drawings from the OP (any OP) makes it easy for them to understand the minor changes that improve the design.
Re: Insulation for steam pipes in basement
1"wall fiberglass and PVC fitting covers. Buy the thumbtacks with the pvc covers. Thumbtacks have little barbs to hold them in place skip the tape it makes a mess.
Trick: put the thumbtacks in the PVC fitting before you put the fitting on the pipe
Re: Bell & Gossett Circulator
You could have just as easily set that unistrut on the floor in front of the basement wall as in the middle of the room.

@dandub1960 with all respect I would rateher leave the pipe bare.
Re: Type K copper pipe
Not sure if anyone mentioned a tracer wire? Anytime we bury plastic pipe we zip tie a tracer wire to it.

Re: Replacing thermostat circuit board in a Taco 006 with a 5 wire fan capacitor?
Your post title implied you were removing the thermostat circuit board and replacing it with a 5 wire fan capacitor ONLY !!!
" I'm adding a relay unit with C wire to enable a smart thermostat, and one way to do it is pull the board from the Taco and replace it with the relay, but I still need a starting cap. "
OK, so what you wrote the board goes away and an unknown relay is added with a 5 wire fan capacitor.
No transformer original or replacement was mentioned. What would you expect a thermostat that was connected to that situation would do ???
I have know idea what your electrical knowledge and skill level is, and what you wrote made little sense to me and apparently others.
BTW (not that it matters) I've repaired and tested many VFDs, from fractional to over 100 HP, I get how the tech works.
I'm still under the impression only you condone what you did and how you did it.

Re: Replacing thermostat circuit board in a Taco 006 with a 5 wire fan capacitor?
@109A_5 I don't believe that the Nest problem had anything to do with the capacitor or anything on the line voltage side of the Taco PCB. The Nest had a problem with this transformer on the PCB.
The problem with removing the PCB to get rid of the transformer, you loose the Capacitor. The Nest likes this transformer relay combination, but the Capacitor is missing so the motor won't operate.
So adding a $10.00 Capacitor and a $30.00 relay/transformer thing gets the system to operate. I just think that a $25.00 relay would be a less expensive, less time consuming, and a less liability way to do the job. But that is just my opinion. The different relay/transformer combination would allow for low voltage to operate the Taco PCB. The Combination relay/transformer that @Jells purchased does not have the ability to do the low voltage contacts, only the line voltage circuit switch is available to turn on the circulator motor. And it all fits inside the electric box on the pump housing.
If the thing fails in the future, then @Jells has only himself to blame and will need to spend the $$$ for fix the failure. But if it lasts for 20 years, then we were all worried for nothing. I often tell my customers that just because it works does not mean it is safe. Like driving your car with no breaks is safe as long as you don't need to stop. But It's safe up to that point. just don't stop! Turn off the motor and coast to a gradual stop. It works for years if you are the only car, until there is another care on the road.
