PME contributing author John Siegenthaler has launched a new website at www.hydronicpros.com containing an overview of the engineering and training services available through his firm, Appropriate Designs. The site also offers an "e-store" featuring a variety of technical publications and software for hydronic heating professions, including "The Hydronics Know-How" CD-ROM, containing over 100 of John's articles from PME and Plumbing & Mechanical magazines.

The tech corner also offers free, downloadable articles on the design of hydronic systems that are exclusively available through the website.
