This allowed us to carry exhaust through roof in just two locations, discharging into VFD-driven chimney fans, minimizing the need for multiple penetrations,” added Brown. “And, with our series, lead-lag boiler arrangement, we set up the system so that each boiler runs for a set number of hours before it cycles off as another system comes on board to meet the need,” continued Brown. “This way, we’ve set equal run time for all of the boilers.” “When demand requires multiple boilers, they activate one at a time until heat needs are met,” said Brown. “We haven’t yet seen a situation where all boilers were on at the same time, though it’s possible. In most instances, just a What’s In Your Hydronics Library? Here at BNP Media, we don’t just do magazines, websites, and webinars. We want to help build your reference library, too. Here are a few publications to enhance your hydronics knowledge, including work by previous ES author John Siegenthaler. See or purchase these, and browse additional books and software, at http://store. bnpmedia.com/store/aec_online/hydronics-radiant/index.html. Also, don’t forget to check our own ES archives for past hydronics features and columns anytime at www. esmagazine.com. • Radiant Precision 2007 Completely revised in 2007— John Siegenthaler, P.E., one of the undisputed leading experts in the field of radiant heating and cooling, has rewritten this book from cover to cover. Radiant Precision is the manual for the RPA’s advanced course in the design and control of radiant panel heating systems. It is also designed for self-study. This book is not for the faint at heart. It is designed for the serious student or consummate expert of radiant heating and cooling. It is filled with the formulas, graphics, and excellent schematics that John has become known for. Within its pages can be found everything from simple tube layout to intense calculations for flow restrictors in manifold assemblies. System design and wiring schematics for the latest in controls are explained in detail. Zoning, hydraulic separation, flow and pressure balancing, buffer tanks, mixing controls, mini-tube systems, proportional- integral-derivative (PID) controls, and multi-load systems are just a few of the topics covered. • How Come? Hydronic Heating Questions We’ve Been Asking For 100 Years (With Straight Answers!) by Dan Holohan This useful book about hot water heating is written in a question and answer format. Some of the systems covered in this book are: gravity systems, indirect radiation, diverter tee systems, loop systems, and radiant heating. One hundred years worth of hydronic heating questions (over 600 in all!) are covered, and answered in plain English. There are also easy-to-follow illustrations. This is a terrific reference book and one you’ll be glad that you added to your library. • Modern Hydronic Heating for Residential and Light Commercial Buildings by John Siegenthaler, P.E. From simple applications to multi-load/multi-temperature systems, you can now learn how to use the newest and most sophisticated hydronic heating materials and methods without compromising between comfort and energy. Heavily illustrated with product shots from top manufacturers, plus more than 300 diagrams of system piping/control schematics, this one-of-a-kind introduction to today’s hydronic heating systems concentrates engineering-level design information into tools that can be used by technical students and professional contractors alike. Thoroughly updated, Modern Hydronic Heating, 2nd Edition now features the latest information on state-of-the-art techniques for use in residential and light commercial buildings, such as: radiant panel heating, injection mixing, primary and secondary piping, use of buffer tanks to improve system stability, and advanced control methods. Ideal for anyone involved in the heating trades, from basic installers to design engineers, this preeminent resource of the North American hydronic heating industry is as well suited for use in a formal education course or for self-study as it is on the job.
