Most of the buildings you visit are probably older than you are because, let's face it, America is a heating museum. Many of those buildings have hydronic heating systems that have been touched by lots of hands over the years and it's your job to get them working efficiently. So let's talk about how those classic hydronic systems work, where they came from, how they've changed over the years, and what you can do right now to get the most out of them without breaking the bank. That's what this book is about. I cover everything from systems that worked purely on gravity to classic radiant systems and everything along the way. Oh, and I promise you a bunch of really good stories before we're through. You will not be bored. Why shouldn't you be the one with the answers? - Dan Holohan
