Re: Radiant flow not pushing fast enough
Though not impossible, I don't think your problem is the circulator.
What happens on a call for heat?
Does the heat call get satisfied?
Does the boiler cycle on high limit?
What is the supply and return water temp?
I'm not sure your circulator is in the right place in relation to the thermostatic mixing valve(in fact i think it isn't but i'm not an expert on that).

Re: Oversized overtall chimney?
Again, forget about the equipment until you fix the thermal envelope of the structure. If you do, it will take far less boiler to do the job. If you just throw more equipment at the problem the utility will thank you for wasting so much energy and paying for it. You don't have to rebuild the house but close the barn doors then think about the boiler. BTW, the standard is to have a blower door test done with infrared thermography, which will generate numbers on just how leaky the house is as a baseline. Once you tighten it up, you can re-test, calculate the improvement, which can then be used to calculate the savings and if further improvement would pay for itself. You can install a TurboBlaster 2000 with the flux capacitor and inverter raterfrazzer but if the building is a sieve you're wasting money.
Re: Radiant flow not pushing fast enough
The circulator needs to be on the output of the mixing valve. Right now, when the hot water supply is above the setpoint of the mixing valve the valve will close and there will be no circulation.

Are you sure you have the right fuel selected for the analyzer.
Your efficiency numbers can’t be correct.

Re: Indirect water heater drywell overflowing?
The well is leaking. Its very common on those tanks.

Re: Pricing on refurbished cast iron radiators
Castrad brings new radiators in through Canada and NYC.
Not all radiators hold up to the 400 degree powder coat ovens.
If it has rubber seals??

Re: Square Plug wrench
If they used Teflon tape it might come out with a standard twelve point socket and a very large breaker bar. Pipe wrenches or fifteen inch adjustable wrenches work sometimes with cheater bars (pipe). Unfortunately, after twenty years the heads have a tendency to snap off when you try to remove them.
Like others suggested, plan on drilling and cutting the plug out.
Re: Square Plug wrench
maybe slightly more if it is a raised square plug but you are probably cutting it out. take most of the middle out with a hole saw then cut 2 slots almost to the threads and knock the wedge out with a cape chisel.
better installers will replace plugs with nipples and caps so they can be removed or are easier to cut out if needed.

Re: Indirect Water Heater not level ?
Only if you have OCD. It will work just fine 1/2 a bubble off
