In the September 1996 edition of PM we ran a feature article about Aztec Radiant Heating title "The 'Waste Not' System Designers," bylined by Jim Olsztynski and Dan Holohan, who collaborated on the coverage and writing. The point was made in that article that the designs and techniques used by Aztec's father - son owners Elwin and Bruce Maur were unconventional, even controversial.
How prophetic! Soon after the article was published, we received a scathing letter from Mark Eatherton, a radiant/hydronics contractor from the same Rocky Mountain area, taking on the owners and their techniques.
