John Abularrage entered the radiant industry back in "the pioneering days" of 1979 when he did research and development for Bio-energy Systems. The company manufactured a product called the Radiant Roll. Abularrage ran a series of experiments in a specially equipped environmental room to determine sizing guidelines.
He's been involved in other aspects of radiant ever since and ultimately founded the precursor of his current company in 1986. Advanced Radiant Design's business is exclusively radiant, with about 65 percent of the work in residential and 35 percent commercial.
