Saving Money by Saving Energy
Depending upon utility rates, pool characteristics, and equipment selected,
it is possible to recoup the premium cost of an upgrade from a standard pump
to an energy efficient pump in the first year of operation.
For example, a system featuring an energy efficient high performance pump
drawing 5.34 amps at 230 volts where the local utility rate is $0.12 per kWh
will cost you approximately $1.78 over a 12 hour period per day. A standard
pump drawing 7.0 amps will cost you approximately $2.32 per day or an
extra $197 annually!
I have a 1 hp pump, low back pressure system, 100 gpm flow, running about 7 amps at 240 volts = 1.7kw. @ $0.129 = 22 cents per hour to run. I run 6 hours per day which is right around 1.5 turns. The cost is $1.32/day. I also run 1/2 hp pool cleaner for 2 hours per day. figure it costs about 11 cents per hour, 2 hours per day. My total daily cost is $1.54 or about $45 per month.
