Direct drive fans increase efficiency and allow for belt-less, maintenance free operation.Modulating speed/capacity equipment that can modulate to meet the exact loads, while staying continuously operational, avoids cycling and puts less wear and tear on the system. Up to 21.3 IEER rating, which is over 1.5x the ASHRAE 90.1-2016 IEER standard.Optimized controls allow for system integration between all modulating components.Modulating technologies allow for highest efficiencies at part-load conditions.Consistent temperature is maintained, minimizing temperature swings and optimizing occupant comfort.Variable speed components adjust heating and cooling capacity to match the required load As defined in the Code of Federal Regulations (CFR), storage water heaters heat and store water within the appliance at a thermostatically controlled temperature for delivery on demand, and have an input rating less than 4,000 Btu/h per gallon of stored water.Fully modulating refrigeration and hot gas reheat components deliver the exact amount of air requested at the desired temperature and humidity.Designed with sustainability in mind, these units are built to last up to 25 years. These units help buildings conserve energy, offer precise temperature and humidity control, superior efficiency, and feature an industry-leading warranty. Technology options for improving efficiency include the use of condensing technology for gas-fired water heaters and improved insulation for tanks on all storage models.High quality DOAS lineup that seamlessly integrates with Rheem commercial systems. The thermal efficiency levels were raised to 80%, matching the current standards for commercial gas-fired storage water heaters, and took effect in October 2015. In 2015, DOE published a final rule amending the standards for commercial oil-fired storage water heaters to reflect the efficiency levels in ASHRAE 90.1-2013. The standards include maximum standby loss requirements and minimum thermal efficiency levels. DOE adopted amended standards for commercial water heaters in 2001 based on the efficiency levels in ASHRAE 90.1-1999. The Energy Policy and Conservation Act (EPCA) requires that if the equipment efficiency levels in ASHRAE Standard 90.1 are amended, DOE must either establish amended standards for the products at the levels specified in ASHRAE 90.1 or establish more stringent standards if they would result in significant additional energy savings and are technologically feasible and economically justified. ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) 90.1 is a commercial building energy code. Those standards were equivalent to the efficiency levels in ASHRAE 90.1-1989. THE STANDARD:Ĭongress established the first national standards for commercial water heaters as part of the Energy Policy Act of 1992. Although there are electric and oil-fired commercial water heaters, gas-fired equipment accounts for most of the energy consumption of this product category. Businesses with commercial water heaters range from office buildings, which typically use very little hot water, to restaurants, which may use large volumes. Commercial water heaters include a wide range of equipment that heats potable water for purposes other than space heating.
