Heat pumps save more on operat-
ing 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 approxi-
mates your local rate. The approxi-
mated 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.
