This book is filled with rare charts, tables, and formulas that will help you both size and troubleshoot steam- and hot-water-heating systems.

I wrote this book for people who prefer plain-English explanations of how things work. You won't find much math in this book. No formulas. No mumbo-jumbo. What you will find are simple words of ordinary conversation, and a lot of very easy-to-follow drawings relating to hydronic radiant heating. There are also stories - lots of them I like to tell stories about the things I've seen as I've traveled around the US, Canada and Europe, looking at hydronic radiant installations. I've seen installers do things the right way and the wrong way, and I learned from them all. I dug into old books as well as the current literature to write this one, and I did my very best to boil down the engineering into understandable terms. This book contains 215 pages of practical, common sense information that you can use right away. I've made lots of analogies to things you already know. Hydronic radiant heating doesn't have to be complicated or spooky. There are rules of thumb that work, and installers are using them with great success every day. There are simple ways to install and control these systems. I'll show you how. All in all, you're going to find straight answers to direct questions in this book. I've done my best to present a subject that I love in a way that I think you will find both informative and very enjoyable.

From simple applications to multi-load / multi-temperature systems, learn how to use the newest and most appropriate hydronic heating methods and hardware to create system the deliver the ultimate in heating comfort, reliability, and energy efficiency. Heavily illustrated with product and installation photos, and hundreds of detailed full-color schematics, MODERN HYDRONIC HEATING, 3rd EDITION is a one-of-a-kind comprehensive reference on hydronic heating for the present and future. It transforms engineering-level design information into practical tools that can be used by technical students and heating professional alike. This revised edition features the latest design and installation techniques for residential and light commercial hydronic systems including use of renewable energy heat sources, hydraulic separation, smart circulators, distribution efficiency, thermal accumulators, mixing methods, heat metering, and web-enabled control methods. Everyone involved in the heating trade will benefit from this preeminent resource of the North American heating industry. It is well-suited for use in a formal education course, self-study, or as an on the job reference.

This was my first book and a true labor of love. I spent decades studying steam and the work of Dead Men, in both old buildings and on library shelves. I traveled the country, haunting used-book stores, looking for engineering books that held the answers to questions that nagged at me. I was obsessed with this topic, and when I finally sat to write, I poured all that I had learned into this book, and as I wrote, I tried my best to make the words sound good to you - like we were together and having a conversation. I wanted you to know what I know and I wanted you to be able to do what I can do when it comes to old steam systems. This book arrived in 1992 and has since gone though dozens of printings. We've sold it in every state as well as in foreign countries. Steam heat is everywhere there are old buildings, so why shouldn't you be the one with the answers? Dan Holohan

If you're replacing a steam boiler, there's only one right way to size that boiler, and that's to measure the radiators. If you're replacing a hot-water boiler, you'll do a heat-loss calculation on the building as it is today, but it also pays to measure the radiation to see if you can reduce the water's temperature and save fuel. The challenge, though, is that it's often difficult to find the ratings for many of those old radiators and convectors, and that's why I compiled this book. I've been saving heating books and heating-manufacturers' literature since 1970. I have a lot of this stuff. E.D.R. is 272 pages of nothing but radiator and convector ratings and if that old unit is out there in the field, it's probably also in this book. This is a terrific resource for any heating professional who wants to get it right the first time.

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. - Dan Holohan

If you're a homeowner with steam heat, know that I wrote this one for you. If you'd like to fix uneven heat and squirting air vents or want to reduce your fuel bills and silence clanging pipes, then arm yourself with this book and smile. This is not a do-it-yourself book. Here's what you'll learn: How your steam-heating system works (and why it might not) What each component does (or what it's supposed to do) Why high pressure in a steam-heating system won't work How the choice of fuels can affect your system What causes all that noise (and how to get ride of it once and for all) Simple ways to lower your fuel bill What you can do yourself When you should keep your hands in your pockets How to find a steam-heating pro (and how to avoid the knuckleheads) Things that should be in every contract you sign for steam-heating work The right questions to ask when replacing a boiler How to fix, move, clean, paint and/or replace an old radiator How to have a hot-water zone added to your steam-heating system How to know if you can have your steam-heating system converted to hot-water heat And a whole lot more Arm yourself with this book. You will not be sorry. Dan Holohan
