The Rheem H2AC™ Rooftop Unit featuring eSync™ Integration Technology delivers air conditioning and water heating from a single source. This system takes the heat removed by a commercial A/C unit and uses it as an efficient source for heating water. H2AC can pre-heat a facility’s cold water supply to as much as 125 degrees Fahrenheit, and Rheem anticipates it can save a building owner or franchisor 50 percent each month on water heating expenses. The system has been recognized with the 2013 Product of the Year Award at the AHR Expo. It also received the R&D 100 Award from R&D Magazine, which honors the top 100 most technologically significant products introduced in the past year.
