Brad was always on the look out for additional methods to produce a cleaner environment so he became involved in the Ground Source Heat pump industry, became an accredited WaterFurnace installer and a member of the International Ground Source Heat Pump Association. Brad carried out an installation of a residential system at Hornsby Heights in Sydney. During this time Brad saw the need for the replacement of gas heaters in the poultry industry where heaters consumed 1.8 ltrs of gas a minute.
