Rheem’s H2AC Rooftop Unit featuring eSync Integration Technology unites a restaurant’s HVAC and water-heating systems to achieve significant efficiencies. The unit works by using heat removed from the restaurant by the HVAC system - which normally would be ejected into the atmosphere - as an efficient source for heating water. When a restaurant has a demand for air conditioning and hot water, this integrated solution switches over from a refrigerant-to-air system, to a refrigerant-to-water system, creating an energy-efficient option due to the heat of the refrigerant being transferred to the water instead of being ejected outside in a normal air-conditioning cycle.
