Re: Replacing iron pipe / Non-filling radiator
The size pipe really has to do with the size of the radiator and` the heat load of the room it is in. In some, many cases 1/2" pex is adequate. It can deliver 15,000 btu/hr
Here is a conservative pipe flow chart. Note the 1" pex is quite a bit less flow than 1" copper due to ID.
A home run with 1/2 pex to each radiator might be an option. Locate a manifold in a 2nd floor closet, feed it with 1" pex. Each radiator could be. zone with manifold actuators or TRVs at the radiators.
An example with a ∆P circulator.

Re: Replacing iron pipe / Non-filling radiator
Changing the pipe to a smaller size may upset the existing balancing. I am not saying you shouldn't go to a smaller pipe just be ready for it. I would not use Pex above 3/4" you will find Pex in the larger sizes difficult. I would use copper.
You need to look at the radiation size to determine which size pipe to use.
As far as the problem radiator goes put a 0-5 or 0-10 psi gauge on the radiator vent location and fill the system until that gauge reads 4-5 psi.

Service weight cast lasts at least a century based on what I've replaced.
XH? Who knows. Note the fittings for XH are limited and it's hard to get a good pour going from XH to Service Weight if you need something like a starter or harp which AFAIK is only available in SW.
PVC isn't the best, just the easiest and cheapest to install.
Re: Nothing happens at all when Beckett boiler reset button is pushed
Check and see if the burner motor has a little red reset button on the motor. Some motors do and some do not. It could have tripped on overload protection.
Probably time to call for service.
Re: Nothing happens at all when Beckett boiler reset button is pushed
Exhaust fan or intake fan? Is the boiler power vented, not using a typical chimney?
If power vent, and the power vent is working, it's possibly a bad end switch in the power vent controls, or the pressure control is doing it's job and preventing the end switch from closing. If it's a combustion air fan, same principle.
Any obstruction outside?

Re: Best Material to Use for Drainpipes in Residential Homes.
pvc drainage fittings were not available in some western states for whatever reason. Lately I see both Pvc and Abs fittings at suppliers.
One step glue is nice for ABS, but the pipe really warps in the sun, on the truck in a sub-rough outside.
Both cellular core PVC and Abs are more fragile. I always buy solid core pvc pipe

Hi, I'm out West, so I like the cast iron stack (to help with keeping it quiet) and ABS for the rest. 🤠

Re: Oil smell after Tiger Loop installation?
I also a have a tiger loop that will sometimes have a faint smell when it vents. Look at the fuel level in the unit when it running. If you see bubbles in the fuel, then the unit should vent. The unit I believe only vents when burner is on as the fuel circulates through the pump.
