Next spring, the U.S. Department of Energy, as a part of the National Appliance Energy Conservation Act, will require higher Energy Factor (EF) ratings on almost all residential gas, electric, oil and tankless gas water heaters. NAECA first addressed water heater efficiency in 1990, and issued updates in 2004 and 2010. The next phase goes into effect April 16, 2015. According to the DOE, these standards will save about 3.3 quads of energy — resulting in about $63 billion in energy bill savings for products shipped from 2015-2044. The. U.S. also should avoid about 172.5 million metric tons of carbon dioxide emissions, thanks to NAECA. Wholesalers and contractors may continue to sell existing water heaters manufactured before April 16, 2015, until inventory is depleted. The products that will be most affected by the new NAECA standards are large-capacity residential and standard gas and electric water heaters. Most standard water heaters will undergo some changes to meet the new minimum efficiency levels, such as added insulation. At Rheem, we have about 40 residential products in our current product portfolio that already comply with the new minimum standards. Our wholesale and contractor customers have likely worked with many of these models. Popular models, such as the following, are NAECA-compliant: The Rheem Prestige™ Series Hybrid Electric Heat Pump Water Heater. With an EF of 2.45, this is the most efficient water heater that Rheem has ever developed. Available in a 50- gal., capacity model, the Prestige Series Hybrid model features a full-color, backlit touchscreen that provides homeowner service alerts as well as detailed diagnostic information for the contractor. It also is compatible with the Rheem EcoNet WiFi module and app. The Them EcoNet app is available at the Apple iTunes or Google Play stores. The Rheem Prestige Series highefficiency condensing power direct vent water heater. This water heater has one of the highest Efs for a residential, tank-type gas water heater (0.82 EF). It has the industry’s best first hour rating of 93 gal., and a recovery rate of 48.5 gal., and it’s also the first water heater to employ high-efficiency condensing technology in a residential tank design.

This is the company’s most efficient tankless water heater to date . Operating at 94% thermal efficiency, this unit vents with PVC piping, making installation faster, easier and cost-effective. Rheem also offers this product in indoor and outdoor models so contractors can recommend the best model for their customer’s needs. The Rheem Classic Plus™ XR90 Extreme Recovery Gas Water Heater. The 29-gal., Rheem XR90 Extreme Recovery gas model heats water faster than a standard 50-gal., gas water heater. What’s more, it has a first hour rating of 90 gal. The small tank size lends itself well to installations since it can fit in some spaces that can’t accommodate larger models.
