2015 Water Heater Regulation - NAECA - Rheem Water Heaters

NAECA 2015 Regulations

Rheem has been achieving higher standards in home comfort for nearly 90 years, so we're more than prepared to meet and exceed new national energy-efficiency requirements for residential water heaters. Powered by our innovative Rheem 360°+1 product design philosophy, we continue to develop advanced solutions that align with homeowners' unique lifestyles and budgets, as well as the highest standards in energy-saving design.

NAECA | National Appliance Energy Conservation Act

Enacted in 1975, NAECA creates uniform efficiency standards for certain household appliances, including refrigerators, dishwashers, clothes washers, clothes dryers and water heaters.

New NAECA Standards

The U.S. Department of Energy (DOE), as part of the National Appliance Energy Conservation Act (NAECA), issued Final Rule energy efficiency mandates in April 2010. While these mandates only apply to products manufactured for sale in the U.S., Canada will soon implement similar increases in efficiency standards. These far-reaching new requirements will have important impacts on water heating manufacturers, distributors, contractors and homeowners.

The Energy Factor

In order to effectively reduce home appliance energy use, conserve more natural resources and generate significant energy cost savings for homeowners, NAECA periodically requires higher energy efficiencies—as measured by Energy Factor or EF ratings—on almost all residential gas, electric, oil and tankless gas water heaters.

These higher energy efficiencies are based on the Energy Factor, or EF, of the unit, which indicates overall water heating efficiency by measuring how much of the energy delivered to the water heater from your power source is actually used to heat your water. The higher the EF, the more efficiently the water heater converts your power into hot water while reducing losses—and the more money you save on overall energy costs.
