An engineer par excellence!
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.

Jack believed in sharing of knowledge and had created two free websites teaching thermal design of Fired Heaters and HRSGs and also provided numerous calculators and scripts for free usage online.
