Re: Weil McClain Evergreen Pro Boiler Line (299, 399, etc) vs Lochinvar Knight XL Opinions
At this point you need to work with the hand you were dealt. Connect a boiler that meets the heat load calculation number. Pipe it properly, good air removal, purge points. etc, etc.
Fire it up on ODR with design set at 180.
Does it heat adequately on the coldest, design day? If so, start cranking down the design supply temperature. Get it as low as possible to maintain your desired indoor temperature.
Enable the outdoor reset function and the boost feature.
Now if the system is grossly under-radiated, that will take a different solution.

Re: Trade school curriculums - how could they be better?
I can only speak of my trade school education which was First Class: Plumbers Local 2 Four Year Apprenticeship, Manhattan & Bronx . We went to school for a full day, every other week and worked side by side under seasoned, Union, Journeyman plumbers.
Along with shop class, we did mechanical drawing, code and theory. As far as Math, it was kept extremely simple...only the important formulae that we were expected to use every opportunity we had.
By the end of 4 yrs, converting decimals to fractions and vice versa, 1.41 for a 45 degree offset, rolling offset, takeoff, et al where ingrained and second nature. Most importantly, we were taught the quick, fast and dirty Rules of Thumb...not long , complicated math problems that Blue Collar guys to sleep 😴. Mad Dog

"How could they be better?" Have the administration and the faculty working together for what's best for the students. If you find that school, you have won.

What resources don't the primary and secondary schools have access to?
Just textbooks and teachers are all that is needed.
My financially strapped school district offered Algebra 1 & 2, geometry, trigonometery, and the beginning of collage level calculus. (late 1960's).
Having taken all of these prepared anyone for any trade school math.

Have you been in a grade school classroom lately? Mayhem! Any education received may be pure luck.
I believe in this day and age more than ever it is incumbent on the parents to assure the students are actually learning.

Re: Old Richmond Furnace looking to replace Fan limit switch.
The existing is two separate controls, where the new one will be a combination fan/limit. Some metal fabrication will need to be done so everything is properly sealed.

Re: Trade school curriculums - how could they be better?
the textbook explains it more or less one way. there are many other ways to explain it and many different algorithms for that matter. if you don't get that particular way you probably aren't going to learn much math in the school systems. different people learn different ways and most school systems don't have the time to explain it different ways to different people.

Re: Trade school curriculums - how could they be better?
Apprenticeships through union are the best way that I have seen. It's a commitment on par with college typically but you are working and being paid the whole time and when you are done you have options. Being union affiliated has some big advantages if for nothing else than the experience you get.

Re: Pex sizing
Join a wood boiler forum or group and you will see literally thousands of people who have had problems with DIY or drain tile type underground lines. Every single one of them is problematic in some way or another. There is no excuse not to just buy the good stuff right away because you WILL end up buying it down the road anyway and have to dig your yard up a second time.
