About the water temperature setting.
GEAppliances.com
The temperature of the water in the water heater can
be regulated by adjusting the temperature setting up
or down using arrow keys on the control panel.
Safety, energy conservation and hot water
capacity are factors to be considered when
selecting the water temperature setting of the
water heater. To comply with safety regulations,
the water temperature setpoint is factory set at
120°F (49°C). This is the recommended starting
temperature setting. nOTE: GE GeoSpring™ Hybrid
Water heater’s energy savings claims are based
on a 135°F (57°C) temperature setting because,
according to uS dept of Energy, the average
residential water heater in the uS is set at 135°F
(57°C). Therefore, the water temperature setpoint
can be raised from the factory setting of 120°F to
135°F (49°C to 57°C) without sacrificing the claimed
energy savings. If a lower temperature setting
than 135°F (57°C) is used, slightly greater savings in
energy and operating costs may be achieved.
If more hot water capacity is desired, increasing
the temperature from 120°F to 135°F (49°C to 57°C)
will enable the same tank of hot water to last about
25% longer because more cold water is mixed in at
the shower or faucet.
Adjust the water temperature setpoint as needed,
always being aware of scald risk.
Water temperatures above 125°F (52°C) can cause
severe burns or death from scalding. Be sure
to read and follow the warnings outlined in this
manual and on the label on the water heater. This
label is located on the water heater near the upper
element access panel.
Mixing valves for reducing point-of-use water
temperature by mixing hot and cold water in
branch water lines are available. Contact a licensed
plumber or the local plumbing authority for further
information.
The chart below may be used as a guide in
determining the proper water temperature for your
home.
DANGER:
There is a hot water scald
potential if the water temperature is set too high.
Households with small children, disabled, or elderly
persons may require a 120°F (49°C) or lower
thermostat setting to prevent contact with HOT water.
Time/Temperature Relationship in Scalds
Temperature Time to Produce a Serious Burn
120°F (49°C) More than 5 minutes
125°F (52°C) 1-1/2 to 2 minutes
130°F (54°C) About 30 seconds
135°F (57°C) About 10 seconds
140°F (60°C) Less than 5 seconds
145°F (63°C) Less than 3 seconds
150°F (66°C) About 1-1/2 seconds
155°F (68°C) About 1 second

To Adjust the Temperature
Press the UP or DOWN arrow on the control panel
key pad. You will be asked to press the ENTER
key to acknowledge that increasing temperature
increases scald risk. Then the temperature can
be increased or decreased by pressing the UP
or DOWN arrows. After the desired temperature
setting has been achieved, you can press ENTER
to accept or simply walk away. (After 3 seconds
of no key presses, the control will accept the new
temperature setting.)
DANGER:
There is a Hot Water SCALD
Potential if the water temperature is set too high.
120°F (49°C) is the recommended starting point for
water temperature setting, but it can be adjusted
to any temperature between 100°F and 140°F
(38°C and 60°C).
