Before I retired from speaking in 2016, I spent decades giving talks about heating systems across the U.S., Canada, Europe and even in the Caribbean. Several times, I even did steam-heating seminars in Hawaii. Life’s funny that way.
I’ll be the first to admit that hydronics can be a boring topic if the teacher (or the salesperson) gets too wrapped up in droning on and on about how to determine gallons per minute, if you know Delta-T or how to figure pump head if you don’t have the plans for the job, and blah, blah, blah. I’ve watched teachers and salespeople do this to a point where their students fall off their chairs or their customers walk away.
