I just returned from Ferris State University in Big Rapids, MI.

It eliminates many of the engineering type questions the techs I have worked with could never answer (like how to properly size a hydronic valve and why). I wanted to get the word out because I really wish I would have been told about this course before I was. Here is a link with info:
