Enacted in 1975, the National Appliance Energy Conservation Act (NAECA) creates uniform efficiency standards for household appliances, including refrigerators, dishwashers, clothes washers, clothes dryers and water heaters.
Residential water heaters manufactured after April 16, 2015 must meet the minimum efficiency standards mandated by NAECA. This will result in $63 billion in energy savings over the next 30 years and a reduction in CO2 emissions of 172.5 million metric tons – that's equal to taking 33.8 million automobiles off our streets!
