Guessing the math may still come up short even by adding 10-15 degrees...not to mention little margin for a boil over...
Limited but steady output less than what pump and pipe size allows spells. Bottleneck somewhere...air,maybe?

Yes very little margin for a boil over, but with constant circulation through 90’ of baseboard it shouldn’t really over shoot much...
I just skimmed through the thread again.. looks like simply he needs a bigger circulator, and more radiation..
Quick and dirty would be a couple T’s and a couple modines depending on piping layout.. but that would get annoying quick in my living room!
Unfortunately now is not the time of year to do doing this stuff..
Either jump all in with a bigger circulator and more radiation, and hope the buried 1” line can supply, or run it and supplement with another heat source inside.

The actual flow rate must be only about 2.27 GPM presuming an accurate 22 degree Delta-T measurement. That means the 15-58 circulator is pumping into about 17.2 ft. of friction head. It seems highly likely that there is a blockage or an airlock somewhere. Either that, or the total length of piping on that loop is in the ballpark of 750 to 1,000 feet.

This afternoon I actually suggested checking into the return policy on this boiler because we all know it's way too big. Then he could take the route of getting a nice second hand stoker boiler like Rob suggested, and do the other things. I realize it's all very bad timing given this time of year.
The boiler did eventually exceed 200 and shut down the combustion air but fortunately it didn't kill the fire this time.
Dave appreciates everyone's input. I didn't see any spigots or valves to power purge the loop with so all that stuff needs to be installed (I'm guessing) to even do that much, unless there is another way.

WOW! They installed it with no boiler drain and no shutoff valves in the whole system?
They were really trying to save a buck. Unfortunately, you may never get the air out of the system.

Lee, you might want to check the baseboards themselves. Sometimes they put bleeders under the covers. Is this a 1 story house? Is the boiler on a piece of ground lower or higher than the house? How do they get water into the boiler? It's an open system so it needs to be checked and filled regularly.

Well, besides a boil situation the fancy controls will kill the combustion air and the fire is in jeopardy of going out and needing a wood infusion in the AM to try and save it.
Please recognize this piping as it stands now is incapable any more increase of flow...forget the bigger pump until the air is purged. Likewise, it is ridiculous to add more rads when there isn't enough flow for the rads it has already.

System opened to install new boiler which allowed introduction of some air and there doesn't appear to be a way to purge the air out.
I'll suggest some PEX fittings, a PEX crimper tool, PEX boiler drains and PEX quarter turn ball valves...for starters...oh. and a Dan Holohan book or two ASAP!

X2, it takes a special "key" tool to crack them open and then back closed...at each and every rad...in one series loop.
This can be a chore. bouncing back and forth for a couple days on your hands and knees...however, some old smart dead guys came up with the "power purge" so they could play on their cell phones during the purge time and skip all that drama of bouncing around and being on their hands and knees in every room multiple times all during a couple of day's time if they got lucky.
