Boiler failure mystery solved: Using the pump curve to diagnose the problem, this Friday's video

After taking last week off to visit the grandkids in Ohio, I have a new video this friday. It talks about a failure of a cast iron boiler after 5 years. I talked about this before but this video does a deep dive on trouble shooting a hydronic system using the pump curve. I had some viewers ask me to go into more detail.
