How To Calculate Pool Heating Costs
When You Use A Pool Heat Pump

This is a cost estimating template. Simply fill in the appropriate numbers and perform the

simple calculations shown. This template will help you to determine the cost of operating a heat

pump designed to heat swimming pools.

A.

Cost Per Kilowatt of Electricity
Note: Call your electric company for your rate

__________

B.

Kilowatt Rating of Heat Pump Heater
Note: Look on Heat Pump Name Plate

__________

Alternate KW Rating Approach
Heater Amperage rating = _______Amps
Heater Voltage rating = _______ Volts
Multiply amps times volts and divide by 1000 for KW

Example: 12 amps x 220 volts = 2640 watts
2640 watts ÷ 1000 = 2.64 KW

C.

Hours per day heater is used

__________

D.

Daily Operating Cost = (A x B x C)

__________

Example:
.09/kw x 2.64 kw heater x 10 hrs/day = $2.37/day

E.

Days in the month heater is used

__________

F.

Monthly Operating Cost = (D x E)

__________

Example:
2.37 x 30 days per month = $71.10

The above example calculations are for a very a small heat pump. Many heat pumps my be
twice as expensive to operate. Note also the high maintenance cost that can arise if the CFC
chemical system in the heat pump fails. Order or download free our special report “How To
