I began writing about hydronic systems for Supply House Times’ parent company BNP Media about 16 years ago. Back then, each column was created on a boxy little Macintosh computer with a 9-in. screen, printed on a dot matrix printer and saved on a 3.5-in. floppy disk. Every month, a printed copy of the column along with the floppy disk were mailed to the editors.
