2015 NAECA Standards for Gas & Electric Residential Tankless Water Heaters

The U.S. Department of Energy has increased the energy factor requirements for residential water heaters effective April 16th, 2015 through the National Appliance Energy Conservation Act (NAECA). This update of regulations will affect all manufacturers selling residential water heaters in the U.S. Residential water heaters include storage type units that store heated water in an insulated tank and instantaneous type units that heat water on demand.

These standards do not apply to electric water heaters under 20 gallons or instantaneous electric water heaters 2 gallons and above.
