Query: No good for design

I'm designing a hydronic boiler/solar heating system for my own home, which I am currently building. I built many systems in the past but haven't been actively doing this for maybe 25 years. I just wanted a refresher. This book didn't help at all. I should have known by the title 'Fundamentals'. It just explains pinciples like water expands when it gets hot.....DUH!There is little if any practical information here.
