I wrote How Come? in a Q&A format, which I love because it reminds me of the old heating texts that line my shelves. This one covers all the classic hydronic systems::
It's a great reference book, and a fine way to get up to speed if you're new to hydronic heating. It's filled with more than 600 questions and dozens of easy-to-follow
illustrations. And if you're not delighted, I'll give you a full refund.
John Siegenthaler (we call him "Siggy") is hydronic heating's
most famous Professional Engineer, and this book became an instant
classic when it first appeared in 1995. This Third Edition takes in the many advances made in recent years. The
text is 744 pages long and loaded with easy-to-follow diagrams and
full-color photos. It's a designer's dream. If you're new to hydronics and looking for a
complete, college-level course that you can savor at your own pace, this
is the book for you.
I was fortunate to have had the late, great
Gil Carlson as one of my teachers. He invented primary-secondary pumping in the early '50s and went on to do many other things. Over the years, I've watched
a lot of trial and error with primary-secondary heating systems. That's a shame because guesswork costs
both time and money. In this book, I've used what Gil taught me to show
you how to reduce the size of your pipes, valves, fittings and pumps,
and how to lower heating system temperature, and all without sacrificing performance or getting into trouble. This book covers two-pipe primary-secondary heating systems, as well as one-pipe
heating systems. It shows how to get the most out of two-,
three-, and four-way valves, as well as injection pumping. I also give you lots of
options for your boiler-room piping (for both single- and
multiple-boiler systems). It's loaded with diagrams and I went easy on the math because you may not be an engineer (and neither am I). This book will save you time and money and keep you out of
trouble. It is not a primer, but it is easy to understand. And it comes
with a 30-day, money-back guarantee.
