Re: Trade school curriculums - how could they be better?
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.

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.

A mono flow system should have its own circulator . Never zone valves and balances valves …

Re: Boiler short cycling?
This failure in the first video and around time stamp 6:23 on the second video remind me of a flame proving signal being lost. More than likely there is a ground path failure in the Flame Rectification path from the UTEC ignition control thru the flame back the the UTEC control That is common when a burner is connected to the rest of the boiler the way your burners are fitted. To be sure the ground path from the burner to the UTEC control is not corroded or compromised I run a physical ground wire from the pilot burner to the GND (BURNER) terminal of the UTEC Control.
Here is an illustration of the wire in place
This wire will eliminate any fault with the ground connection present from the burner to the control
Re: Trade school curriculums - how could they be better?
a good friend was a teacher at a community technical college for many years, solar and hydronics
Before he retired a few years back he noted a majority of the 1st year students could not solve a basis math problem. That makes for a steep hill to climb for plumbing and heating students. Maybe some better testing and prerequisites
