PM columnist John Siegenthaler is an industry authority on designing and installing hydronic systems. He’s been writing “Hydronics Workshop” since July 1996 for the magazine.
In May, at the Radiant Panel Association annual meeting, John will release “PM’s Hydronics Toolbox” — a compilation of his PM columns, along with a new “Hydronics 101” section. The book promises to be a powerful tool for contractors looking to better understand hydronic fundamentals.
