The upcoming revision to the
National Appliance Energy
Conservation Act, otherwise
known as NAECA, will
impact the design of most
new water heaters.
APRIL
16
2015
The U.S. Department of Energy (DOE) regulates
minimum energy efficiency requirements for water
heaters. The first set of regulations—known as
the National Appliance Energy Conservation Act
(NAECA)—were created in 1990 and later updated
in 2004 to the current standards. A new update to
the rules for increasing minimum energy efficiency
standards was enacted in 2010 and goes into effect
on April 16, 2015.
At American, we are already preparing the
necessary design changes to our line of
residential water heaters. But as someone
in the building community, you need to
understand how these changes will impact
your designs and plans, too.
These design changes will require that most
residential water heaters under 55 gallons of
capacity produced after April 16, 2015, to be larger
in size. Therefore, they will require more installation

space in both single-family and multi-family housing.
Most water heaters under 55 gallons will grow by
approximately 2” in height and diameter. Units over
55 gallons will require even more drastic changes.

learn more about the upcoming changes and our
recommendations to meet the future challenges.
