SUPPLEMENTARY INFORMATION :

A. Bccnc,nouoo

Development of test procedures is one

discrete part of the energy eorlservation

program for appliances. Even when preomulgateci, final test procedures will not

of themselves require L--sting to be conducted. They will merely establish standLrd methods for testing when testing vs

otherwise required by the Act itself or by

regulations implementing other harts of

the program. For example, the Federal

"Prude Comnnission h -j. exercising

its appliance energy efficiency labelling;

c.•utho city regarding a par; titular appliance type, may well require the application of substemetially less tiwm.n all of the

finel t_nst procedures applicable to that,

further proposal of Subpart C will be

necessary in order to meet the requirements of section 325 (a) (1) of the Act as

amended by section 161 of the Energy

Conservation and Production Act (Pub.

L.94-385)

Subpo.vt A, r. previously proposed

19;.77, - 14, 1976; 42 FR 15 33,

March 22, lu'77), contained definitions in

proposed section 430.2, some of which are

applicable to the test procedures for

"Basic model" 2 subparagraph (5) applyirlg speci_rcally to water heaters, by

r"propc _rig the definition of "electric

of "water heater," "gas water heater,"

and "oil .v.iter heater,"

By notice issued July 22, 1973 (:4

31237, July 27, 1076), FEA proposed ^an

amendment to proposed Part 430 to add

a Subpart B which would contain the appliance test procedures-required to be

prescribed by section 323 of the Act.

The notice issued July 22 described the

requirements of section 323 and set forth

proposed test procedures for room air

conditioners. A further notice issued

March 21, 1977 (42 FR 16311, March 30,

"+_977) solicited comments with respect to

a clarification of the provision concerning the number of units to be tested. By

notice issued March 17, 1977 (42 F.R

15423, March 22, 1977) FEA proposed an

amendment setting forth proposed test

procedures for dishwashers. Test procedures for several other products are in

the process of being proposed at this

time.

Section 323(a) (2) of the Act requires

FEA to direct the National Bureau of

Standards Act (NBS) to develop for 13

types of covered products test procedures

for the determination of the estimated

annual operating costs and at least one

other useful measure of energy consumption which FEA determines is likely to assist consumers in making purchasing

decisions. Pursuant to the Act, ERA directed NBS to develop test procedures

for FEA's use in prescribing test procedures under the Act. As part of this

undertaking, IBS was required to evaluate existing test procedures for measuring energy consumption of water heaters.

NBS has transmitted ta FEA a test

procedures review document which reviewed existing test procedures for measuring energy consuunption for water

heaters and recomrmencled test procedures. Copies of this review document

will be made available for inspection by

Interested persons as provided for later

in this notice.

Under the Department of Commerce

Voluntary Labelling Prog- a r1, proposed

test procedures and labeling procedures

for water heaters were published as Voluntary Specification No. 5-75 on August

14, 1975. A final specification was prepared In December 1975. Final publication of these voluntary proced was

withheld upon enactment (- A k

These test methods were ueveiuf..d at

S with cooperation from ti , Gas

Appliance Manufacturers Association.

These tests are based on the American

NL-J'Pior,<,.l Standards (ANSI) Z21.10.1 a

c._pected generally to reduce the testing

B. !fE,%WRT_S OF ENERGY CONSUMPTION

The Act requires F'EA to prescribe test

»rocedures for the deterrnination of estimated annual operating costs and at

least one other useful measure of energy

oonsiunption which the administrator

determines is likely to assist consumers

in conking purchasing decisions. The estimated annual operating cost, proposed

for both electric water heaters and gas or

oil water heaters in s 430.22(e) (1), is

based upon daily energy consumption, a

representative average use cycle of 365

days (representing the total number of,

Jays in a year) and representative aver

age unit energy costs.

Also proposed (§ 430.22(c' (2) ) as test

procedures for the determination of

other measures of energy consumption

which are likely to assist consumers in,

making purchasing decisions are test

procedures regarding the energy factor

for water heaters. The energy factor is

defined as the daily water heating energy

to the daily energy consumption. The

daily seater heating energy represent,

the heat content of the average amount

of water provided by the water heater

per day. Among other possible applications, the energy factor may be used by

FEA to determine the efficiency of hot

water heaters for the purposes of the

efficiency improvement program described by section 325 of the Act.

An additional proposed ineasus'e

(§ 430.22(e) (3)) that is likely to assist

consumers in making purchasing decisions is the hot water supply rating

which is a measure of the amount of

water that can be supplied by the water

heater in a given period of time.

FEA recognizes that there may be additional useful measures of energy corisurnption for water heaters other than

the measures described above. Accordingly, today's proposal, in proposed

§ 430.22(e) (4), provides for other useful measures which the Administrator

determines, are likely to assist consumers

i?1 making purchasing decisions. These

measures, however, must be derived from

the application of the uniform test

method proposed today as Appendix E to

Subpart B. Water heater manufacturers

would, if required, only have to perform

various computations while still applying

only the same test method contained In

Appendix: B. For example, if the AdFEDERAL REGISTER, VOL. 42, NO. 81-WEDNESDAY, APRIL 27, 1977

home usage, as measured by utility companies In various parts of the United

States.

The total energy consumption calculated for the water heater system is

based on the use of 64.3 gallons per day

and a 90° F temperature rise. These

numbers are used as the reference.

traps installed In the piping system.

Piping losses are included In the calculated energy and are accounted for in

the coeifcfents used (i.e., the 61.3 gadIons per day and 90° F rise). The baseline water heating system configuration

is essentially a water heater without an

integral heat trap, and with a piping

system characterized by vertical pipe

risers from the cold water inlet and hot

water outlet of the water heater. U11inspl ateci pip ug fosse; ccci be reduced by

,using a heat trap on both the inlet and

NBS have shown that a 12 watt savings

can be obtained by a heat trap on the

inlet side (cold water pipe) and 16 watts

on the outlet side (hot water pipe). The

heat trap reduces piping losses by preventing hot water movement out of the

v-Ler he-ter which then cools and return,; through the pipe to the w ester

D. REPRESENTATIVE Av.:ACL-USE CYCLE

Section 323 (b) (2) (42 U.S.C. 6293(b)

(2)) of the Act provides that test procedures for determining estimated annual

operating costs of any covered product

shall be 'calculated from iiic rrurements

Cl e _ergy is is C,. lel}rcscncatiie av r

age-use cycle as determined by the Adnir t.•ator) and from representative

average unit costs (as provided by the

Administrator) needed to operate such

product during such c cic. lEA has de=

termined that the representative avere-use cycle for water heaters is 365

days per year, since water heaters typically are used every day of the year.

Typical, or standard, values for the

representative average volume of hot

n'ater usage and temperature rise occurring in producing hot water also are

necessary elements in the estimated annual operating cost and the energy factor of ter heaters. FEA is using 64.3

gallons per day and 90 F temperature

rise for these two values, respectively,

in the test procedures proposed today.

The 90° P temperature rise represents

the national average inlet water temperature: for the U.S. of 55° F and the

usual factory thermostate setting of

145° F. Normally, at the factory, gas and

oil water heater thermostats are set at

140° F and electric water heater

thermostats are set at 150° F. The 64.3

gallons per day of hot water was

derived from information obtained

from a, survey conducted by NBS, of

a number of gas and electric utility

companies regarding hot water energy

usage data. Data supporting these usage

conditions are available in the NBS test

procedure review document as provided

for later in this notice.

FDA. in ends to develop representative

average unit costs of energy needed to,

calculate the annual operating cost for

the representative average use cycle and

to provide this, information to manulecturers and the FCC on or before- the

effective date of test procedures for water heaters.

E. NUMBER OF UNITS To BE TESTED

'Proposed § 430.23 (e) v, ould provide for

sampling of each basic model to be tested

when testing of water heaters is required

by the Act or by program regulations of

H. ENVIRONMENTAL AND INFLATIONARY

RsvIEw

As required by section 7(c) (2) of the

Federal Energy Administration Act of

1(;74 (Pub. L. 93-275 ), a copy of this

notice has been submitted to the Administrator of the Environmental Protection

Agency for his comments concerning the

impact of this proposal on the quality

of the environment. The Administrator

has no comments.

The National Environmental Policy

Act of 1969 requires FEA to assess the

environmental impacts of any proposal

by the Agency for "mtlajor Federal actions

significantly affecting the quality of the

human environment." Since test procedures tinder the conservation program

for appliances will be used only to stanclardize the measurement of energy usage

and will not ifert the qufiitity or distribution of energy usage, FEA has determined that the action of prescribing

test procedures, by itself, will not result

in any environmental impacts. On this

basis, PEA has determined that, with

respect to prescribing test procedures

under the conservation program for appliances, no environmental impact statement is required.

The proposal has been reviewed in accordance with Executive Order 11821 as

amended by Executive Order 11949, and

O Circular No. A-107 and has been

determined not to be a major proposal

requiring evaluation of its economic impact as provided for therein
