How To Calculate Pool Heating Costs
When You Use The SolarAttic PCS1 or PCS2

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

swimming pool heater that coverts hot attic air into swimming pool heat.

A.

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

__________

B.

Kilowatt Rating of SolarAttic PCS1/PCS2 Heater

.396/.660

Alternate KW Rating Approach PCS1/PCS2
Heater Full Load Amperage rating = 1.8 Amps/6.0 Amps
Heater Voltage rating = 220 Volts/ 110 Volts
Multiply amps times volts and divide by 1000 for KW

SolarAttic PCS1= 1.8 amps x 220 volts = 396 watts
396 watts ÷ 1000 = .396 KW or 660 ÷ 1000 = .660 KW

C.

Hours per day heater is used (MAXIMUM)

10

D.

Daily Operating Cost = (A x B x C)

__________

Example: 10 hours per day is typical run time
.09/kw x .396 kw heater x 10 hrs/day = $.35/day

E.

Days in the month heater is used

__________

F.

Monthly Operating Cost = (D x E)

__________

Example:
.35 x 30 days per month = $10.50

Operating the SolarAttic™ PCS1 swimming pool heater only involves the small amount of
energy required to operate the PCS1’s fan motor. A small electrical consumption can be attributed
to the solar controller, but like solar panel systems this is an insignificant amount of electricity. The

PCS2 was designed to have extra static pressure handling capabilities for use with ducts or other
heat enhancing apparatus. Full load amperage is 6.0 amps reflecting the 1/2 hp motor used in the
PCS2 vs. the 1/4 hp motor used in the PCS1. The motor will only use the amount of current it needs
and the PCS2 is expected to operate only slightly higher as the PCS1 ($15/mo vs. $10/mo).
