Case Studies

EDC Technologies Savegas control and monitoring technology has been around for almost 40 years, successfully providing proven energy savings to thousands of customers across the nation.

Founded by Terry Pfaff in 1984 and incorporated in 1987, EDC's Savegas control technology has gathered and recorded over 39 years of historical energy savings control data on

thousands of centralized hot water systems. 


Over these any years, EDC Technologies has worked closely with various Utility companies such as PG&E and SoCal Gas and reputable energy consultants across the nation, recording and documenting energy savings case studies on different types of centralized hot water systems. Since 1984 EDC has gathered and documented proven energy savings with our Savegas control technology in various forms, from Case Studies to public Work Papers.
