Original author of Winheat suite of software



WinHeat suite of software was originally written by Jack Hardie of Conroe, Texas.

Jack was a mechanical engineer and he designed, manufactured and installed hundreds of waste heat boilers, heat recovery steam generators, and direct fired heaters throughout the world for over 45 years for some of the world’s largest oil and gas companies. Jack was a lifetime member of American Society of Mechanical Engineers (ASME) and was well-known and respected throughout the industry.
