6311(1);
(ii) That has a rated storage volume of less than 20 gallons; and
(iii) For which there is no federal test method applicable to that
type of water heater.
(c) The test method for hot water dispensers is as follows:
(i) Connect the hot water dispenser to a water supply, a power
supply, and a means of measuring energy use. Fill the hot water
dispenser with water and apply the power supply. Control the ambient
temperature in the laboratory at 77°F ± 7°F throughout the test.
(ii) Let the unit operate in standby mode for at least two complete
cycles of thermostat operation, with the thermostat set to 150°F ± 10°F
as described in (c)(iii) of this subsection.
(iii) If the thermostat is adjustable, set it to produce water at
150°F ± 10°F, determined by discharging five oz. of water into an
insulated cup immediately after a thermostat cut out, then measuring
its temperature.
(iv) If the thermostat is adjustable, and the temperature is not
within the tolerance shown in (c)(ii) of this subsection, readjust the
thermostat and allow it to operate in standby mode for two cycles,
measuring the discharge temperature immediately after the second cut
out, as described in (c)(iii) of this subsection.
(v) After the thermostat has been properly adjusted, allow the unit
to operate in standby mode for a minimum of two cycles, then measure
the electricity used (in Wh) during the next twenty-four hours (plus
time for first cut out after twenty-four hours). Begin measuring
electricity usage immediately after a thermostat cut out, and end just
after the first thermostat cut out after twenty-four hours. The total
length of the test will be somewhat longer than twenty-four hours,
depending on the first cut out after twenty-four hours. Divide the
measured electricity used (in Wh) by the time (in hours), to obtain the
standby loss (in watts).
(vi) Record the water temperature measured in (c)(iv) of this
subsection and the standby loss calculated in (c)(v) of this
subsection.
(d) The test method for minitank electric water heaters is as
follows:
(i) Storage tank volume. Determine the storage capacity of the
water heater, in gallons, by subtracting the weight of the empty water
heater from the weight of the water heater when completely filled with
water (with all air eliminated and line pressure applied) and dividing
the resulting net weight by the density of water at the measured
temperature.
V = Wf - Wtρ
Where:
V = the storage capacity in gallons
Wf = the weight of the water heater when full (lb)
Wt = the weight of the empty water heater (lb)
ρ = the density of the water (lb/gal)
(ii) Test set-up
(A) Insulate the water piping, including heat traps, if provided by
the manufacturer, for a length of four feet from the connection to the
appliance with material having a thermal resistance I value of not less
than 4°F x ft2 x hr/Btu. Ensure that the insulation does not contact
any water heater surface except at the location where the pipe
connections penetrate the appliance jacket.
(B) If the manufacturer has not provided a temperature and pressure
relief valve, one shall be installed and insulated.
(C) Maintain the temperature of the supply water at 70°F ± 2°F and
the pressure of the water supply between 40 psi and the maximum
pressure specified by the manufacturer. The accuracy of the pressure
measuring devices shall be within ± 1.0 pound per square inch. The
water heater shall be isolated by use of a shut off valve in the supply
line with an expansion tank installed in the supply line downstream of
the shut off valve. There shall be no shut off means between the
expansion tank and the appliance inlet.
(D) Before starting testing of the water heater, the setting of the
thermostat shall first be obtained by supplying the water in the system
at 70°F ± 2°F and then noting the maximum mean temperature of the water
after the thermostat shuts off the electric supply to be 142°F ± 8°F.
(E) For measuring the energy consumption, instrumentation shall be
installed which measures within ± 2 percent. Voltage shall be within
± 10 percent of the rated voltage.
(F) Three or more temperature sensing means shall be installed
inside the storage tank on the vertical center of each of three or more
non overlapping sections of approximately equal volume from the top to
the bottom of the tank. Each temperature sensing means is to be
located as far as possible from any heat source or other irregularity,
anodic protective device, or water tank or flue wall. The anodic
protective device shall be removed in order to install the temperature
sensing means, and testing shall be carried out with the device
removed. If the temperature sensing means cannot be installed as
specified, placement of the temperature sensing means shall be made at
the discretion of the testing agency so that comparable water
temperature measurements are obtained. A temperature sensing means,
shielded against direct radiation and positioned at the vertical
midpoint of a tank type water heater at a perpendicular distance of
approximately twenty-four inches from the surface of the jacket, shall
be installed in the test room.
(G) The ambient air temperature of the test room shall be
maintained at 75°F ± 10°F. The ambient temperature shall not vary more
than ± 7.0°F from the average during the test, temperature readings
being taken at fifteen-minute intervals and averaged at the end of the
test.
(iii) Standby loss. Fill the water heater with water. Turn on the
electric power to the water heater. After the first cut out, allow the
water heater to remain in the standby mode until the next cut out. At
this time, record the time, ambient temperature, and begin measuring
the electric consumption. Record the maximum mean tank temperature
that occurs after cut out. Record the mean tank temperature and the
ambient air temperature at the end of the first fifteen-minute interval
and at the end of each subsequent fifteen-minute interval. The
duration of this test shall be until the first cut out that occurs
after twenty-four hours. Immediately after the conclusion of the test,
record the total electrical energy consumption, the final ambient air
temperature, and the time duration of the standby loss test (t) in
hours rounded to the nearest one hundredth of an hour and the maximum
mean tank temperature that occurs after cut out. Calculate the average
of the recorded values of the mean tank temperatures and of the ambient
air temperatures taken at the end of each time interval, including the
initial and final values. Determine the difference (ΔT3) between these
two averages by subtracting the latter from the former, and the
differences (ΔT4) between the final and initial mean tank temperatures
by subtracting the latter from the former.
Determine the standby loss (W) using the formula:
W = S x K x V (ΔT1) / (3412 Btu/kWh)
Where:
ΔT1 = 70°F, the nominal difference between mean tank temperature and
the average ambient air temperature
S = standby loss, hr-1
K = 8.25 Btu per gallon °F, the nominal specific heat of water
V = tank capacity expressed in gallons
3412 = conversion factor from kWh to Btu/hr

residential pool pumps, and portable electric spas:
