GE is introducing a water heater to meet the new
2009 DOE ENERGY STAR
®
standards for heat-pump
water heaters. Energy Factor = 2.35 EF*
Designed to use approximately half
the energy and save $320 per year.*
Standard 50 gallon electric water
heater uses ~ 4880 kWh per year.
GE’s new water heater uses ~ 1856
kWh per year.
* Energy Star requirement is 2.0 EF or higher
* Based on 10.65 cents per kWh.

Condenser
The condenser is
wrapped around
the tank, foamed
between the tank
and the outside
cabinet.
The condenser is
non-replaceable.

Installation – Condensate Drain
The 6’ main condensate drain
hose is pre-attached. The 3”
overflow tube is connected
during installation.
Easy to miss location of recessed
nozzle for main drain hose.
6’ main drain hose should be
directed towards suitable floor
drain.
Condensate water volume is
equivalent to a small
dehumidifier or 4000 BTU air
conditioner.

Modes of Operation
eHeat Mode – most energy efficient mode - uses only the sealed system. The
time required to heat water is longer, but should be adequate for normal
demand households. It will take 3-4 hours to initially heat a tank to 120F at
room temperature (4-6 hours in a colder room). Approximately one hour to
reheat from a 10 gallon flow.
Hybrid Mode – combines the energy efficiency of eHeat with the recovery
speed and power of the electric elements. The control automatically uses
efficient eHeat unless the majority of hot water is consumed.
Standard Electric Mode – uses the upper and lower heating elements to heat
the water. Heats water the fastest, but is the least energy efficient mode.
High Demand Mode – use this mode if your household has higher than
average water usage. The control will automatically use efficient eHeat if
water usage is normal, but when demand is higher, then standard electric
will be used.
26
Three Heat Sources
The water heater has 3 heat sources:
1. Upper heating element
2. Lower heating element
3. Condenser
Only ONE heating source can be on
at a time.
The upper heating element has
priority. If a large temperature
increase is required, the upper
element is used (except in eHeat).
The lower element and condenser
are both considered “lower” heat
sources.
27
Mini-Manual
The mini-manual is taped to the inside of the front cover.
Four Phillips screws (2 on each side) hold the covers together.
28
Cover Installation
The covers have a lip that fits into a groove in the base. When
reinstalling, use the filter to hold the rear cover in place.
29
Sensors
The water heater has five
sensors.
Four of the sensors provide
the control with sealed
system information.
The T2 sensor provides info
on the tank temperature.
All sensors have a negative
coefficient resistance.
As the temperature
increases, the resistance
value decreases.
