HEAT PUMP ENERGY
SAVINGS
Heat pumps save more on operating costs during the
heating cycle than heat/cool models. The table below
shows that the higher initial cost of purchasing a heat
pump is quickly made up in lower operating costs.
Use the map to identify the climate zone’s designated
number. Reading down the left--hand column of the
table, select the cost/kWh rate in this zone that most
closely approximates
your local
rate. The
approximated savings and payback period is found at
the intersection of your zone/rate line and the desired
Btuh Cooling Capacity column. Exact savings are
determined by lifestyle, local electrical rates, and
climatic conditions.
For more precise energy savings in your geographical
location, go to www.lodgingAC.com to use Carrier’s
energy calculator.
