With a W.I.S.E. loan, it’s easy to fi nance high-effi
ciency heat pump systems and other qualifying
energy effi ciency improvements!
Any residential customer who receives electric
service from an OMPA member city is eligible for a
Qualifi ed residential customers can receive a below-market
interest rate for either an unsecured loan or a
home equity loan for energy effi ciency improvements.
Examples of qualifying measures include new heat
pumps and air conditioners, extra insulation, storm/
thermal windows and doors, caulking, weather-stripping,
programmable thermostats, ceiling fans,
attic ventilation fans, etc.
W.I.S.E. loan fi nancing is available through the
Bank of Oklahoma (BOK) for amounts ranging from
$1,000 to $100,000, depending on whether applying
for an unsecured personal loan or a home equity loan.
Repayment schedules are 36 months to 15 years,
again dependent upon the type of loan requested and
the loan amount. The fi nancing covers everything
needed for proper installation and operation of the
• No down payment is required
• Quick application turn-around
• Below-market rates
• Fixed rate for the life of the loan

Heat pumps provide both heating and cooling
capabilities in one system, using refrigeration
equipment to supply warm air in the winter and cool air
in the summer.
Electric heat pumps do not burn fuel to make heat. Instead
they move existing heat from one place to another. In the
winter, the unit takes heat from outside and pumps it into
your building. In the summer, it takes heat from inside
and pumps it outside, just like a central air conditioning
unit. Heat pumps have a higher overall effi ciency rating
than other systems, because they move heat rather than
We encourage our residential and commercial customers,
HVAC contractors and builders to purchase and install
one of three types of heat pumps:
* Geothermal (ground-source) heat pump (GHP)
* Air-source heat pump (ASHP)
* Dual-fuel heat pump (DFHP)
Geothermal heat pumps typically use water (or
antifreeze) circulated through looped pipe buried in the
ground to heat and cool. In the winter the liquid absorbs
the earth’s heat and in the summer the heat is removed
from the building and transferred to the earth.
The effi ciency of air-source heat pumps falls during
extremely cold weather and backup heating is usually
needed. Air-source heat pumps often use electric strip
heating for backup. Dual-fuel heat pumps are air-source
heat pumps that use a gas or propane furnace as
backup heating. Dual-fuel systems take advantage of the
effi ciencies of both units.
Replacing your current heating and cooling system with
a heat pump or high-effi ciency air-conditioner may cost
more up front, but you will see savings on your heating
and cooling costs year round!
Still need another good reason to install a heat pump
or high-effi ciency air conditioner? If you install an
approved unit you could be eligible for a rebate and/or a
Customer/location must receive electric service
from an OMPA member city that participates in the
WISE Rebate Program.
Residential (single-family and multi-family) and
commercial/industrial customers/locations qualify.
Each customer/location can only qualify once for
these rebates, unless
- signifi cant building additions cause the
installation of additional heat pumps or air
- at least ten years have elapsed since the
previous rebate award
Mobile homes do not qualify (with rare
Electric heat pumps and/or air conditioners must
- be permanently installed split or single-packaged
units (window units do not qualify)
- be certifi ed by the Air Conditioning, Heating
and Refrigeration Institute (AHRI) - see
www.ahridirectory.org for certifi ed equipment
- meet the program’s minimum effi ciency standards
DFHP installations must also meet the following
-an outdoor thermostat must ensure that, under
normal operating conditions, the electric heat
pump heats the house whenever the outdoor air
temperature is above 40°F.
-the indoor thermostat must be wired so that, when
outdoor temperatures exceed 40°F, the auxiliary
heat source will operate only when the indoor
thermostat is manually set on the
“emergency heat” setting.
GHP installations must have an operating desuperheater
installed (in most cases).
GHPs installed with gas (natural gas or propane) backup
heating systems will not qualify for the GHP rebate but
will qualify for the DFHP rebate.
*Until March 2012, an additional rebate of $1,000/ton is
available for qualifying GHP systems- ask about the OCP
