principal of Appropriate Designs, a consulting engineering firm in Holland
Patent, NY. The second edition of his text, Modern Hydronic Heating, and
recently released software, Hydronics Design Studio, are now available through
adjustment to high demand. Simpler transport. Attractive installation and
mounting profiles. These and other benefits can accompany a multiple-boiler
strategy, especially if you follow some tips on piping and sensor placement.
Review what may become a new paradigm as popularity increases in North America.

Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
