Energy-Efficiency

Single speed pump: inexpensive to install, but costly to operate. How costly?  A single speed 2hp Wisperflow pump costs $1049 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 $2249 for the first year.

Multi speed pump: more to install, but economical to operate.  A Pentair 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 off your electricity bill.

With an initial cost of $1750 and an annual energy cost of $200, the first year total would be $1950. This is less money than the single speed pump, meaning that a multispeed pump can pay for itself in about a year. 

What to think long term?  Usage cost is more important than initial expense because it recurs every year.  Over a course of five years, the multispeed option will save an 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
  
• Decreased  water velocity results in less wear and tear on heaters, cleaners, and filter grids
• Better filtration -- slower filtration traps finer particles in the filter 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
