CERTIFICATION AND APPROVALS

UL – UL-174 applies to Residential Electric Water Heaters

The following paragraph describes the relationship between ASHRAE, NAECA and the

Department of Energy’s ENERGY FACTOR as it relates to the residential electric product lime.

All of the RELIANCE residential electric water heaters meet this code.

The American Society of Heating, Refrigeration and Air Conditioning Engineer (ASHRAE)

guidelines follow the National Appliance Energy Conservationist Act (NAECA). NAECA follows

the Department of Energy (DOE) test procedures of the 1990 code of federal regulation, title 10,

part 430 (64) which establishes minimum Energy Factors (EF) for water heaters of 12 kilowatts

or less and a storage capacity of at least 20, but not more than 120 gallons.

Formula (as of January 2004) -The minimum EF allowed = .97 - .00132 x V (volume of storage)

Example (EES-52; 50 gal. x .00132 = .066 Then .97 - .066 = .904 minimum allowable energy

factor).
