Saving Money, The Old Way
Single speed pump: inexpensive to install, but costly to operate. How costly? A single speed 2hp Wisperflow pump costs $1134 to install and $1200 a year for electricity (assumes a 6 hours a day filtration time). This means that the cheap way costs a a total of $2334 for the first year and $1200 for each year after that.
Saving Money, The New Way
Multi-speed pump: more to install, but economical to operate. A variable speed pump runs between $1750-$1850 installed and programmed (after Edison rebate), but costs only around $175-$400 a year to operate. This could easily save up to $1000 a year on your electricity bill.
With an initial cost of $1715 and an annual energy cost of $200, the first year's total would be $1950. This is less money than the single speed pump, meaning that a multi-speed pump can pay for itself in about a year.
When considering a pump, usage cost is more important than initial expense because it recurs every year. Over a course of five years, the multi-speed option will save the average home owner about $4000.
Why slower is better: When a pump runs at one-half the normal speed it uses only one-eighth of the energy. When a pump runs at one-third the normal speed, it uses only one-twenty-seventh of the energy.
These savings allow for longer run times. Less stagnant water, more consistent chemical levels, and a substantially lower utility bill.

Variable Speed Benefits
- Saves money -- year after year
- Saves equipment -- decreased water velocity results in less wear and tear on heaters, cleaners, and filter grids
- Better filtration -- slower filtration traps finer particles in with less pass through
- All day economical circulation -- no stagnant water in the hot afternoon
- Better for salt chlorinators -- salt systems only work when the pump runs
- Better for ozonators -- ozonators only work when the pump runs
